0 | Why is an empty Unity Iphone Build over 700 Megs? Is this Normal? So after 2 weeks of slaving over my first game I was finally done! I was entirely ecstatic....until I saw its file size. 770 Megabytes For a simple numbers game, that was way too much and I created an empty unity project as a test and that was also over 700 megs Why is an empty Iphone project this large? |
0 | Does Unity store temporary autosaves for scripts? If not, how do I avoid data corruption My PC lost power in the midst of a save(twice in a row) and I've lost my scene setup as well as a script(its contents actually). I would like to know if there are any fail safes for saving files. If not, how would I prevent future data loss corruption. |

0 | Shader that draws just vertex points The game I am developing is in unity and I want to make a shader which can be put on a mesh that only 'draws' color on each vertex point. I am not proficient with shaders, and out of all my searching I have come up empty handed I unfortunately don't even know how to look up this question (I seem to only find results about point clouds, which only serves to confuse and scare me more P). Any help or if you can point me in the right direction on what to search, I would be very much greatful. |

0 | Can a generic class inherit from MonoBehaviour? Expanding upon a previous tutorial, I am adapting a follow script to support multiple variations of a Bezier spline. Each spline variation uses a custom interface called IBezierInterface, and the follow script accesses the method GetPointOnCurve() to determine the correct position. In theory, this all seems very simple. However, I appear to be running in to some trouble. While I intend to pursue the general issues a bit more, myself, I realise that I may be shooting myself in the foot with the generic implementation. While I can find a lot of good examples demonstrating the correct use of generic types, I can not find anything that gives an example of a generic class that inherits from another class. For example, Microsoft documentation includes examples of inheritance as a restriction on the actual type, and an example of inheriting from a generic class but there are no examples of a generic class that inherits from a standard class. Unity documentation has even less examples, but none pertaining to my query. I am not getting errors but that is no guarantee against error. I can not conceive a good prototype model to test my theory, either, given the fact that I am fairly new to the concept of generic types. Given that I am specifically needing my class to be a MonoBehaviour can I make a custom generic class that inherits from MonoBehaviour, such as in my example? public class SplineWalker lt T gt MonoBehaviour where T IBezierInterface ... |

0 | Game is darker on build I've been recently doing test builds of my game. In Unity, I worked on baking the lighting to ensure everything looked fine. However, upon building, the game level becomes far darker and much of the lighting and baking is ineffective. Here is how the scene looks in the editor And here is how it looks in the built game It's much darker than intended. Here are my lighting settings which I've baked in Unity's Editor. These settings and lightmap parameters were designed to, at least in the editor, provide decent quality while making light bake times relatively quick. However, I've noticed that newer Unity's Lighting settings are way different now, so perhaps something is amiss here? I've been at my wits end trying to figure this out for the past while, but I can't figure out why this is happening or how to fix it. Any ideas? |
0 | Make Unity game using files directly from game directory For stats of enemies, and several other kinds of info, I've decided to use not inspector fields or hardcoded values, but to store values to some XML and other types of files, and read them from scripts, obtaining required values. And I want this files to stay in game folder, not packed to .assets file, because I'd like to have possibility to quickly modify this values without need to rebuild whole game. So, how can I mark asset in editor, that it should not be included to .assets, but stay in unchanged form in game folder? UPDATE I will slightly rephrase what I want to achieve. I need possibility to have file in game directory, so I can read it from game, and I'd like to have this possibility in both editor and built game. So, as for answer, I will also receive information about what folder is considered as game folder in editor. |
0 | Unity3D, how much code do you write? I'm curious to know the workflow when creating a game in Unity3D? Does it generate a lot of code for you? My understanding is that you describe the game in Unity and do scripting on the back end to do the logic. Kind of like you use Unity to describe the puppets and you use a scripting language as the puppet master. |

0 | Align spawned particle system I am working on a game in which tanks can shoot at each other. I intend to spawn a spark particle system (particles emit to Z) when a bullet hits a surface.

0 | How do I manually draw a part of a sprite sheet? I'm working in Unity, and I'm finding that the animator isn't working for what I'm trying to do, in my 2D game. I want to build a specific animation, using sprite sheets, and be able to reuse the same animation with other sprites that are the same size and dimensions by cells. After some research, I find that it is impossible. Instead, I'm trying to create my own animation script, but I don't understand how to tell Unity to draw only a section of the sprite. Something like in XNA, where you could render only a specific rectangle of a sprite using start and end coordinates. How do I manually draw a part of a sprite sheet? |
0 | Make the texture array node work with cubemaps? I am working on a procedural interior mapping shader in Unity's Shader Graph. Ideally, I'd like to feed it a set of cubemaps it can pick from semi randomly. However, it seems that by default the texture array asset one can provide to a graph does not support reading cubemaps. Does anyone have a way to use this, or perhaps a clever custom node or alternate texture mapping, so that I can read a number of cubemaps into the shader semi randomly? Preferably an arbitrary number, but even a fixed number would be somewhat of an improvement. |

0 | Unity associated game object is null when running I am just starting with Unity. I have two UI Text game objects, Atext and Btext. I have associated them by drag dropping with my PlayerController script public variables, say public Text atext and public Text btext. Before running, the Unity editor correctly shows that Atext and Btext are correctly associated with the public variables. When running with debug, I get a null reference exception with btext and even the Unity Editor shows the association as None (Text). After stopping, the association turns to Btext as it is supposed to be. The script is very simple and I don't set btext to null at any point. When I create a new UI Text object by duplicating Atext, it works correctly after associating it with some new variable. When I create a new UI Text object by Create UI Text, it doesnt work Might be a stupid question but what am I forgetting? Edit Here is the problem again with code Before running with debug, the editor shows PlayerController2 (Script) Script PlayerController2 Speed 7 Countboxref Countbox(Text) Winboxref Winbox (Text) Brokenboxref Text (Text) where Countbox, Winbox, and Text are Canvas UI Text objects which I have drag dropped into place. Winbox object has been created by duplicating it from Countbox, Text has been created by Create UI Text. enter using UnityEngine using UnityEngine.UI using System.Collections public class PlayerController2 MonoBehaviour public float speed public Text Countboxref public Text Winboxref public Text Brokenboxref private Rigidbody rb private int boxit void Start () Countboxref.text "count" Winboxref.text "winner" Brokenboxref.text "broken" When the program breaks on line Brokenboxref.text "broken , the editor shows Brokenboxref None (Text) and when the execution is stopped completely, it again returns to Brokenboxref Text (Text) Note 1 In this project, every Text object created with Create UI Text is broken. A new Text object works only when I select Countbox or Winbox and duplicate it. Thus it is not possible that the object would be explicitly destroyed in the code. I can create as many Text objects as I wish by copying (all don't work) and as many Text objects as I wish by duplicating (all will work). Note 2 when I create a new project from scratch, of course everything works as expected. I assume the project is somehow corrupted. Edit 2 No prefabs or such. Just the basic roll a ball tutorial. But this was my son's project so I am not sure what he has done when following the tutorial. Note 3 The problem went away when I deleted the Library folder and forced Unity to rebuild it. Don't know yet if I caused any other problems by doing that. I saw that somewhere as a suggestion for corrupted projects. I don't know if there is a proper way to refresh. Also, this project was originally started with Unity 4.6 and upgraded to 5.02 |
0 | Use constant force to hold something in position This may actually be more of a Physics.SE question but since im doing this in Unity I figured I'd ask here. I am playing around with the Constant Force component and have a sphere constrained with a linear configurable joint (y axis free). With one key I apply a force in one direction to get it moving, but then when i press another key, I want to stop it and hold exactly in place by using an opposite force. So even if some other rigid body hits the sphere, it wont move until I remove a force. Unfortunately, Unity doesnt allow more than one constant force on a gameobject (probably a good reason, not sure exactly) and I know if I do a net force, that it would just end up being 0, which would kind of work but the sphere would move if it gets hit. Another thing I tried was to take the spheres current force and constantly flip it from positive to negative every FixedUpdate but that didn't seem to work at all. I know the quick and easy way would be to just set velocity to zero, but I see tons of comments saying that modifying velocity directly breaks the physics, is bad form, etc. and I want to do this as properly as possible. The best way I can describe what I'm trying to do is like that science experiment where you take a ping pong ball and use a blower to push just enough air to counter gravity and the ball seems to hover in place. My only difference is that my constraint is side to side instead of up down. |

0 | Splitting a character model to ease animations I've recently been looking into animations within Unity, and came across the idea of splitting my humanoid character's object into two at the waistline. The Idea being that animations used for movement can be applied to the legs, without interfering with general upper body animations stances (and vice versa). Is this a viable option and would there be any adverse effects from doing this? Also, is there any real need? I've noticed Unity is quite flexible when it comes to animations, but am unsure whether unity would be able to handle this? My main issue is different weapon types, where I would like the hands in different idle positions, but without having to have 4 or 5 different running forward animations. |
0 | Unity3D Button Slicing Problem I'm having trouble getting my button to appear correctly, as you can see in the image below, the right and top sides are stretched out and not displaying properly. I cannot figure out if this is a problem with the image itself or something wrong in the way I'm setting up the button. Here are the settings in the inspector window Here is the original image UPDATE So everything looked fine when I just opened up Unity, so I tried to figure out what I did last time for it to make this switch. It happens when I build and export the scene to my Android device. |
0 | How to rotate a skybox cubemap using Unity Shadergraph Seyed Morteza Kamali solved his own problem of rotating a mesh cubemap with shadergraph here How can I rotate cubemap in shadergraph? However, I have a starry night cubemap inside my Skybox shader done in Unity Shader Graph, and as there is no way to directly attach a script to a Skybox material, I've been accessing the skybox material and the shader via external script. I've been using the Bolt visual scripting, and with this script, it is fairly easy to access other properties of the skybox but not the rotation (4x4 matrix). It is possible to access floats, vector2's, texture maps and even the Cubemap, but even if I have set the cubemap rotation, which to my knowledge has to be done with a Matrix 4, as an Exposed property, when trying to access it, e.g with FindPropertyIndex it gives the value 1, indicating that the property is not found. Edit ok, I found this in the Unity documentation Matrix parameters are not exposed in the material inspector, but can be set and queried with SetMatrix and GetMatrix from scripts. As far as I understand the documentation, the example assumes a mesh renderer, which the skybox doesn't have. Another idea would be to use 3 vectors, which could be exposed and then apply the rotation somehow to them at the same time, I did some tests in this, but all I managed to create was to distort the cubemap. Again I am not trying to rotate the entire skybox, but just a cubemap inside the skybox shader this would allow different rotations to daytime clouds and nighttime stars. Would be best if everything could be done inside ShaderGraph, with the speed and axis values published as properties. A custom function perhaps? I am using URP 7.2.0 and Unity 2019.3.0f6. |
0 | How do I safely change properties on my skybox? Usually in Unity, when your scripts make changes to something at runtime, those changes are not persisted back to design time. This is generally considered a good thing. But for whatever bizarre technical reason, this does not apply to shader properties on materials. If you change something while the game is running, it stays changed! Generally the way to get around this is with a MaterialPropertyBlock, which also helps avoid generating a lot of garbage. But MaterialPropertyBlocks work with Renderers, which leaves out one rather important material the skybox. Right now, I have code that says RenderSettings.skybox.SetFloat( quot PropName quot , value) , and it's incredibly aggravating because it always needs to be reset afterwards. RenderSettings doesn't have a SkyboxRenderer property that I can use in conjunction with a MaterialPropertyBlock, so how can I change shader settings on my skybox and make them not persist after I exit play mode? |

0 | Unity keeps reseting my Input Manager settings Basicaly, title. I want to change the second Horizontal entry in the Input Manager but when I do it won't save the changes afterwards. I rename the second Horizontal axis to "Strafe", and I'm reffering to it in the script like that, but when I run the game I get this error "Input Axis Strafe is not setup". This is because there's not input axis called "Strafe", because Unity just reset the default settings for some reason. There's no save button on this window, and I actually got it to save one time and it worked, but the next time it didn't and it reset the axis again! How can I avoid this? I set it up nicely Then it screws me over after running the game once |

By default, Unity's keyboard navigation for buttons seems to check for GetButton rather than GetButtonDown if a menu has 5 items and I hold the down arrow, it'll scroll very quickly to the bottom.

0 | Infinite 3D Cave in Unity A friend and I are hoping to make a game in Unity in which you fly through an infinite 3D cave that can twist and wind in any direction (though obviously not to the point that the turns are impossible to make). We were thinking about creating a number of tunnel "pieces" that each curve a certain amount, and spawning each at the end of the one that came before. But we have no idea how to make sure that the mouth of one tunnel piece always aligns perfectly (in both position and rotation) with the end of the previous one. Can anyone offer any advice on how to accomplish this? Are we even going about it in the right way, or is there a better way to procedurally generate the cave? Bonus points It'd be awesome if the cave could change in diameter and or shape as well, though that'd just be gravy. |
0 | (How exactly to use EventSystem?) Assigning string Name to UI Button in Unity without CrossPlatformInput? I'm trying to make a new game for Android. There is a Jump button i've added as UI button , this works fine as I have a method for Jump() which I can just add to the OnClick() method in the Button's Inspector tab. However, for my 'Pick Up' button I don't really want a method for pick up. I already have my item pickup handling code inside a OnTriggerEnter() method and what I was hoping to do was have an additional if condition into my code like if (Input.GetButtonDown("Pickup")) then it ok to pickup! This is how i did it in my other projects. But I had been importing the CrossPlatformInput namespace and then just copied and adapted the buttons from the Jump button that came as standard with that. So now, I can't see how to name my button as 'Pickup'. I tried looking at the code from CrossPlatformInput, it seems it takes the name you provide it, and passes it to VirtualInput (also in the CrossPlatformInput namespace), I couldnt see a copy of this class anywhere, it think its closed source maybe Of course, I could probably manually make a method to add to the OnClick() which just makes a bool true only when it's being clicked. But I feel like there must be a way to just add this UI button as 'Pickup' to the Input system (like you do with "Horizontal", "Vertical" or "Jump" for example). Again, I tried to read the docs, and also lots of forums and sites like this. I found that the EventSystem will (or should) have the part I need, but i am now stuck. I tried this EventSystem.current.currentSelectedGameObject.name ?????????? I read that will return the name of the most recent button pressed, but how would that method know that my new Button is called "Pickup", I dont see how I added it to that yet? Another reason why i'd like to do it this way is for Cross Platform compatibility. If I make it this way, I already now that there is a certain button on the keyboard mapped in Project Input to the same name (ie. "Pickup" Left Ctrl). And it seems cleaner to use the existing way of doing this if possible, im sure its just that I dont know how yet. Most options ive seen online involve the OnClick inspector function, or CrossPlatFormInput imported package. I hope this makes sense to someone, and that there is a way to do it. Thanks for any help as usual very much appreciated. |
0 | Is Apple Game Center Multiplayer Online? I'm trying to build a real time multiplayer game on Unity.

0 | Combining meshes up to certain sizes I have the following spritesheet for types of terrain, with a transparent background. To draw it on my map, I thought of doing one mesh per type, and then combine them. This is the code. This gave me at first quite good results. But then I started trying maps of bigger dimensions, and after a certain point (I think it was 49x49), I got suddenly different results. As you can see, at this point only seems to render 2 kinds of terrain, and the others have disappeared completely. Size is the only factor that was changed. Materials, Sprites, settings... everything else is completely the same. Why could this be happening? |

0 | Unity multiplayer (online) How to connect to a 'Client Host' without using Unity Paid Service I'm slightly annoyed with the official Unity guides here, because I have been following through some, and they have indeed helped me create a local network mulitplayer situation. However, at no point did they mention that using these methods (ie. UnityEngine.Networking NetworkManager NetworkManagerHUD NetworkIdentity) will require me to pay Unity for Pro, and a monthly server usage fee, if I wanted to play via internet. I've set up my own Rust server in the past and it was very simple. I just installed a Rust Dedicated Server on my desktop PC (which I have fibre internet connection) and ran the server. I could then have 20 people playing with me and we didn't notice any slow down or lag or any problems with it. (Rust is made in Unity I believe) I've tried searching lots on this matter, and there are many many differing voices of how I can do this (many out of date, and many explicitly stating its impossible without hiring a server) I disagree, and think I can make my desktop run the server, BUT I haven't a clue if I'm correct and also how I would be able to make it. Unity docs seem to be trying to hide this solution if it exists (perhaps I'm being paranoid). I have the NetworkManagerHUD all working and can play locally as I say. So, it appears that the NetworkManager allows a user to start my game in 'Client host' mode, it also allows another instance elsewhere to click "Connect Client" and has a space for IP address. Would I even need a dedicated server if a player has clicked to start as 'Client Host'? assuming I don't, how can I then connect to this host from another machine? Does typing the client hosts external IP allow this? Sadly, I don't have anybody to help me test this right now. If a dedicated server version is the preferable way to go, could anybody please help me in the direction of how to start creating this? For info The game at this stage is a very simple FPS shooter. The NetworkManager is assigning the 'isLocalPlayer' flag correctly to one instance of the player object. I see in the Editor Hierarchy that it is handling the game overall and has two player objects once I have logged in with two instances locally. |

So when i use MovePosition and MoveRotation, how do i rotate it based on the camera perspective mouse movement? I think the movement Vector is ok so i can simply rewrite the FixedUpdate to something like rigidbody.MovePosition(movement speed Time.deltaTime) but i am totally stuck on how to apply the camera rotation to my rigidbody to use it like void FixedUpdate() move the rigidbody rigidbody.MovePosition(movement moveSpeed Time.deltaTime) rotate the camera camera.transform.localRotation Quaternion.AngleAxis( mouseLook.y, Vector3.right) but how can i rotate the rigidbody based on the cameras rotation??? rigidbody.MoveRotation(?????)

For some reason, when I create two audio Sources in an object only the latest one is ever used, even if I explicitly keep objects separated, playing a clip on one or the other plays the clip on the last one that was created, furthermore, either this last one is not created in the right place or somehow messes with the rolloff rules because I can hear it all across my level, havign just one source works fine, but putting a second one on it causes shit to go batshit insane.

0 | How to achieve a dynamic soft see through hole effect in a wall with shaders? I'm looking for a way to create a dynamic soft see through hole effect for room walls. I know a few ways how to do it (for example multitexturing with second layer being the hole mask in screenspace), but all involve rendering walls with blending on which is too expensive for the mobile project I'm working on. Is there any way to do this without using blending on the whole geometry (the hole can appear in any place on any wall). Please see the attached image for a better illustration of the effect Also, I'm very open to any links to papers tutorials that might not be solving the exact problem but doing something close that might get me on the right tracks. Thank you! |

0 | Remove or skip splash screen from Unity Free Personal game binary for modding How can I modify a Unity game (Windows) binary to skip the 5 second Unity logo splash screen? I know how to mod game code using dnspy to modify Assembly CSharp.dll. I'm able to find isShowingSplashScreen but that appears to be irrelevant. I'm at a loss whether I can find the splash screen code in any .dll or if one would have to edit the game .exe or some other file. Looking at the game .exe in HxD (hex editor), I see multiple occurrences of unity SplashScreen but have no idea whether I can use this for anything. Background I'm modding a Unity game and I am not very good at it. I have to try a lot and start the game a lot. This means each time I test something, I lose five seconds because the game was made with the free Unity version. As a player I made no commitment to the Unity ToS. I also have no intent to distribute a modded file that removes the splash screen. However, I want to remove it during development. I am not asking how to remove the splash screen while building the game. I am not developing in Unity, I am modding a game made in Unity and I'm trying to streamline the process. I did see Unity remove logo in splash screen, Alternatives to remove Unity splash screen after developing a game with the free version?, Can I legally remove the default Unity splash screen by removing it from the APK?. They revolve around the question of removing the splash screen with intent to distribute, which is not the topic here. I had hesitations about asking this question, due to the answer being useful to developers willing to violate the ToS. However it seems on topic and legal. I would also argue that the solution to my problem is probably going to be too much effort for active game dev projects to bother using it (having to repeat the steps for each new update) and that quot bad apple quot devs would rather use pirated versions of Unity Pro. |
0 | Unity3d select empty gameobjects in scene I have a pathing system that I am creating in Unity. When you add nodes to denote the path, I create a empty GameObject and render it in OnGUI as a square. The problem that I have is clicking on the object in the scene view. I am trying to figure out what would be the best way to click the Node, so that I can move and rotate the Node. I had some ideas, like Creating a Cube or some other GameObject with a mesh, and change the layer to Node. Then make the camera cull out the Node layer. Only in editor mode, create a temp asset and delete it before runtime. Do a raycast and see what objects are near the click, then pick the closest one. I have a feeling that I am putting to much thought into it, and suggestions would be greatly appreciated!! |
0 | How does Unity Inspector handle values changing during play without any thread locks? First of all, I'm a Java coder. Usually, when you write a game, you run it on thread different than the UI one like pseudocode starts new Thread(new Runnable() Override public void run() while(someVolatileBoolean) input() physics() graphics() and then you declare some sort of listener for the input which usually works on application UI thread so you need to mark it as volatile, atomic or perform a basic synchro using the synchronized keyword (depending on the situation). Let's take a simple Unity script public class SomeMovementScript MonoBehaviour public Vector3 speed new Vector3(0.1f, 0, 0) void Update () this.transform.Translate(speed Time.deltaTime) If we then play the game, the object starts to move with speed 0.1f. Now, when the game is playing, we can change the speed variable through the inspector I thought from the UI coder point of view I'm changing a variable, which is being read each frame by the game thread. How does this happen, that I don't get some sort of ConcurrentModificationException if there's no visible synchronization at all. The variable is public, not being cached in any way. I know that this question should be asked on SO, but I thought that GD has more users specialized in Unity and it's mechanics. I came up with immutability. Variable is considered thread safe if it's state can't change. As components are immutable, and classes like Vector2 3 4 are immutable it would work. But... You can make your own class Serializable , mark their fields as public and the class is not thread safe but it is visible through the inspector. How does Unity Inspector perform these real time updates with all the classes you can think of? |

0 | Making object move in an angle I have a game with a beat em up perspective (think Final Fight, Streets of Rage) where movement is in X and Z. My movement logic consists of checking controller input of X axis for X movement and Y axis for Z movement. I use this logic to move enemy as well, using this method internal bool MoveTowardsPosition(Vector3 targetPosition) bool reachedPosition false bool reachedX false bool reachedZ false Determine x direction if (Mathf.Round(Mathf.Abs(targetPosition.x enemy.transform.position.x)) gt 0) if (targetPosition.x lt enemy.transform.position.x) Input.HorizontalMove 1 else Input.HorizontalMove 1 else reachedX true Determine z direction if (Mathf.Round(Mathf.Abs(targetPosition.z enemy.transform.position.z)) gt 0) if (targetPosition.z lt enemy.transform.position.z) Input.DepthMove 1 else Input.DepthMove 1 else reachedZ true if (reachedX amp amp reachedZ) reachedPosition true return reachedPosition So what happens here is that given a target position, I add to the HorizontalMove (X) and DepthMove (Z) until the enemy reaches the destination (these X and Z additions will be read on Update to do a transform.translate()). The enemy does move to the destination but in a unnatural path. So when Z is larger, it will reach the destination X first then traverse Z. So for example, X 2 and Z 5, it'll traverse with a path like this What I'm trying to do is for it to traverse a path like this I figured instead of adding fixed 1 1, I need to determine X and Z based on that angle but I'm lost on how to compute do it. Can you guys lend me a hand, please? |
0 | Rotate 3D object relative to the camera I really need the help of an expert. I'm trying to rotate an object in all 3 axes relative to the camera in response to the gamepad sticks. I have succeeded but with an unexpected error, depending on its orientation, the object can rotate in the opposite direction of the stick direction. For example, if the object is on its back, when I move the stick to the left the object rotates to the left. But, when the object is facing the camera, when I move the stick to the left the object rotates to the right. The same happens in all 3 axes, on each axis I have 180 degrees with the correct stick orientation and 180 degrees with inverted sticks. Also, both the camera and the object can freely move adding more complexity to this problem. I would like to find a way where the orientation of the rotation always follows the direction of the stick. This is solved with a minus sign applied to the angle according to the object orientation (relative to the camera) but I can't find out how.

0 | Unity C Input Buffering So, I've got a fighting game with some pretty tight input windows, and I'd like to buffer the inputs for a few frames. Basically, if the fighter is in the neutral state, pressing attack should lead into an attack. It uses Input.GetButtonDown("attack") to get the button, and if it detects a press, transitions into attacking state. Now, let's suppose the fighter has just landed, and ends up hitting "attack" a few frames before the land animation ends and he transitions back into neutral. As of right now, nothing would happen, since he's not in the neutral state where the check is, and when he enters the state, the button press is no longer happening. Is there a way to store inputs for a few frames, so that I can read a button press a few frames back? So, instead of using Input.GetButtonDown("attack"), it'd be something like InputBuffer.KeyBuffered("attack",12) to see if the button was pressed within 12 frames? The example above is just a bit of a simplification, I know for the above situation I could just use GetButton instead of GetButtonDown, but for a fighting game, you can imagine that the necessary inputs to buffer would get significantly more complicated. |

0 | Unlock levels using coins Unity I'm creating a game that has multiple levels. The first three levels are free but the others can be unlocked either using coins (collected during the game) or through IAP. For the coins, I'm using a binary formatter to store the number of coins.

For example, if a level requires 500 coins and the user has 600, then on clicking this button the level is unlocked and the total coins now available are 100. And if the number of coins are less than what is required to unlock a level then the user should not be able to unlock that level. I'm not sure how to implement this. |
