3,553,244 | 0 | Android OpenGL ES and 2D <p>Well, here's my request. I don't know OpenGL already, and I'm not willing to learn it, I want to learn OpenGL ES directly since I'm targeting my development to android, however. I want to learn OpenGL ES in order to develop my <em>2D</em> games. I chose it for performances purpose (since basic SurfaceView drawing isn't that efficient when it comes to RT games). My question is: where to start? I've spent over a month browsing Google and reading/trying some tutorials/examples I've found anywhere but to be honest, it didn't help much and this is for two reasons:</p> <ol> <li>Almost <em>all</em> the articles/tutorials I've came across are 3D related (I only want to learn how to do my 2D Sprites drawing)</li> <li>There's no base to start from since all the articles targets a specific things like: "How to draw a triangle (with vertices)", "How to create a Mesh"... etc.</li> </ol> <p>I've tried to read some source code too (ex.: replica island) but the codes are too complicated and contains a lot of things that aren't necessary; result: I get lost among 100 .java files with weird class names and stuff.</p> <p>I guess there's no course like the one I'm looking for, but I'll be very glad if somebody could give me some guidelines and some <em>links</em> maybe to learn what I'm up to (only OpenGL ES 2D Sprites rendering! nothing 3D).</p> |

12,724,893 | 0 | Android AndEngine : sprite.detachSelf() doesnt remove the sprite <p>I'm creating small balloon game. where balloons pop up randomly and disappear after a little while.

37,094,776 | 0 | <p>There is a major flaw in your design. The error is obvious. In this line</p> <pre><code>final helpers helpers = new helpers(); </code></pre> <p>you are trying to create an object of an activity which is a very very bad practice. You cannot simply create an object of an activity like this. All Activities in Android must go through the Activity lifecycle so that they have a valid context attached to them. In this case a valid context is not attached to the helper instance. So as a result the line </p> <pre><code>SharedPreferences sharedPref = this.getPreferences(Context.MODE_PRIVATE); </code></pre> <p>causes a null pointer as 'this' is null. (Why? Because this refers to the context which has not yet been created as the activity is not started using startActivity(intent))</p> <p><em>Another thing though this is not an error, you must use activity names starting with an upper case letter. It is the convention followed and will make your code more readable. Your code is pretty confusing due to the weird use of upper and lower case names. You declare your class with a lower case letter while at some places the variables are upper case. which causes confusion. The rule is that classes, interfaces, etc should start with upper case letters and variables as lower case.</em></p> <p>So in this case what do you do?</p> <p>You never start your Helper activity and I think you do not need to show it to the user. That is it needs to do some work without user interaction. You should make it a service. And then start it using <code>startService(intent).</code>Or you may also create it as a Java class, depends on your use case. </p> <p>Edit: By the way I answered <a href="http://stackoverflow.com/questions/37092965/android-calling-intentservice-class-from-a-service-class/37096620#37096620">another</a> similar question having the same problem but involving services later today. </p> |

Once done zooming, using graphic context take the frame size of the bounding view, and take the image with that. Eg Uiview contains scroll view which has the zoomed image. So the scrollview zooms and so does your image, now take the frame size of your bounding UIview, and create an image context out of it and then save that as a new image. Tell me if that makes sense.</p> <p>Cheers :)</p> |

40,384,206 | 0 | <p>I found a solution! Thanks largely to <a href="https://turbofuture.com/computers/Creating-Dynamic-Charts-using-the-OFFSET-function-and-Named-Ranges-in-Excel-2007-and-Excel-2010" rel="nofollow noreferrer">this page</a>. Here's what I did:</p> <p>I created made a named range using this formula: <code>=OFFSET(Report!$B$1,1,0,COUNTIF(Report!$B$2:$B$30,"<>-"),1)</code></p> <p>For that to work, I had to change all the empty cells to output <code>"-"</code> when empty in stead of <code>""</code>. I couldn't get <code>COUNTIF</code> to accept <code>"<>"""</code> or <code>"<>"</code> or any other weird tricks I tried. Using <code>"-"</code> was easier.</p> <p>That makes a dynamic named range that changes size as I put data into the sheet. I named a similar range for everything I'm trying to chart (Approved Status, Call Ready, Not Ready). The chart was able to accept those names and now it's dynamically sized. If I only have three agents on the sheet, it shows three huge bars. With twenty, it shows twenty bars (exactly what I was looking for).</p> <p>One other tip: I changed my first row to output <code>""</code> when empty, so that <code>COUNTIF(Report!$B$2:$B$30,"<>-")</code> always returns at least 1 (otherwise you get annoying errors because you have a named range referencing a 0-length array).</p> |

23,432,284 | 0 | <p>Well, you can check if a variable is an array or string using instanceOf or typeOf or .constuctor: See here <a href="http://tobyho.com/2011/01/28/checking-types-in-javascript/" rel="nofollow">http://tobyho.com/2011/01/28/checking-types-in-javascript/</a> </p> <pre><code> if(myVariable instanceOf Array){ //multi select } else if(myVariable.constructor === String){ //single select } </code></pre> <hr> <p>or you can simply convert your string to an array and check the length of the array.</p> <pre><code> $scope.myVariable = $scope.myPreviousVar.split(','); // or however you want to delimit this if($scope.myVariable.length === 1){ //single select } else if($scope.myVariable.length > 1){ //multi select } </code></pre> |
