copied!<p>I am really pulling my hairs our with this funny issue. I am doing my loadingscreen. The smallBox will move to right according to asset manager loading percentage. I received "FATAL EXCEPTION: GLThread 2967" when i try to setX() for my smallBox. I tried resize() but no luck, same error. I am not sure where i went wrong.</p> <p>Here is my code:</p> <pre><code>public class LoadingScreen extends AbstractScreen { private Image bigBox, smallBox; private Stage stage; float loadingPercent=0f; private SpriteBatch batch; private Texture loadingTexture; public LoadingScreen(game game) { super(game); // load asset here Gdx.app.log("gamelog", "assetManager.load()"); game.assetManager.load("img/loading.pack", TextureAtlas.class); game.assetManager.load("img/splash.pack", TextureAtlas.class); } @Override public void show() { stage = new Stage(); batch = new SpriteBatch(); loadingTexture = new Texture(Gdx.files.internal("img/loadingTexture.png")); loadingTexture.setFilter(TextureFilter.Linear, TextureFilter.Linear); TextureRegion bigBoxTr = new TextureRegion(loadingTexture, 0, 0, 800, 480); TextureRegion smallBoxTr = new TextureRegion(loadingTexture, 0, 790, 800, 110); Image bigBox = new Image(bigBoxTr); Image smallBox = new Image(smallBoxTr); smallBox.setX(-800); smallBox.setY(160); bigBox.setX(0); bigBox.setY(0); stage.addActor(bigBox); stage.addActor(smallBox); } @Override public void render(float delta) { // Clear the screen Gdx.gl.glClearColor(0f, 0f, 0f, 1f); Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); loadingPercent = Interpolation.linear.apply(loadingPercent, game.assetManager.getProgress(), 0.1f); Gdx.app.log("gamelog", "LoadingScreen: =" + (-800+(int)(loadingPercent*800*2)) + " getProgress" + game.assetManager.getProgress()); smallBox.setX(-800+(int)(loadingPercent*800*2)); //<------ problem point smallBox.invalidate(); if (game.assetManager.update()) { Gdx.app.log("gamelog", "LoadingScreen: before calling SplashScreen =" + (-800+(int)(loadingPercent*800*2)) + " getProgress" + game.assetManager.getProgress()); game.setScreen(new SplashScreen(game)); } stage.act(delta); stage.draw(); } </code></pre> <p>error log on LogCat</p> <pre><code>11-01 22:08:54.308: I/awesomegame(24701): LoadingScreen: =-800 getProgress0.0 11-01 22:08:54.318: D/memalloc(24701): /dev/pmem: Unmapping buffer base:0x51f68000 size:10297344 offset:9527296 11-01 22:08:54.328: W/dalvikvm(24701): threadid=11: thread exiting with uncaught exception (group=0x40c2ca68) 11-01 22:08:54.328: E/AndroidRuntime(24701): FATAL EXCEPTION: GLThread 2967 11-01 22:08:54.328: E/AndroidRuntime(24701): java.lang.NullPointerException 11-01 22:08:54.328: E/AndroidRuntime(24701): at com.example.awesomegame.screens.LoadingScreen.render(LoadingScreen.java:128) 11-01 22:08:54.328: E/AndroidRuntime(24701): at com.badlogic.gdx.Game.render(Game.java:46) 11-01 22:08:54.328: E/AndroidRuntime(24701): at com.example.awesomegame.somegame.render(somegame.java:25) 11-01 22:08:54.328: E/AndroidRuntime(24701): at com.badlogic.gdx.backends.android.AndroidGraphics.onDrawFrame(AndroidGraphics.java:487) 11-01 22:08:54.328: E/AndroidRuntime(24701): at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1463) 11-01 22:08:54.328: E/AndroidRuntime(24701): at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1217) </code></pre> <p>However, bigBox display correctly when i comment out line "smallBox.setX(-800+(int)(loadingPercent*800*2)); //<------ problem point".
