ANDENGINE Old [初始屏幕錯誤]

我是Andengine的初學者，所以我帶GLSE1練習我的第一個遊戲代碼。我試圖顯示一個啓動畫面，但它總是在「紋理」（不能實例化類型紋理）和「createFromAsset」中顯示錯誤。ANDENGINE Old [初始屏幕錯誤]

我對下面的啓動畫面的完整代碼：

    @Override 
    public Engine onLoadEngine() { 
    this.mCamera = new Camera(0, 0, CAMERA_WIDTH,CAMERA_HEIGHT); 
    return new Engine(new EngineOptions(true, ScreenOrientation.LANDSCAPE, new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT), this.mCamera)); 
    } 
    @Override 
    public void onLoadResources() { 
    this.mTexture = new Texture(512, 512,TextureOptions.BILINEAR_PREMULTIPLYALPHA); 
    this.mSplashTextureRegion = TextureRegionFactory.createFromAsset(this.mTexture,this, "gfx/Splashscreen.png", 0, 0); 
    this.mEngine.getTextureManager().loadTexture(this.mTexture); 
    } 
    @Override 
    public Scene onLoadScene() { 
    this.mEngine.registerUpdateHandler(new FPSLogger()); 
    final Scene scene = new Scene(1); 
    /* Center the splash on the camera. */ 
    final int centerX = (CAMERA_WIDTH - this.mSplashTextureRegion.getWidth())/2; 
    final int centerY = (CAMERA_HEIGHT - this.mSplashTextureRegion.getHeight())/2; 
    /* Create the sprite and add it to the scene. */ 
    final Sprite splash = new Sprite(centerX, centerY, this.mSplashTextureRegion); 
    scene.getLastChild().attachChild(splash); 
    return scene; 
    } 
    @Override 
    public void onLoadComplete() { 
    } 
    } 
    enter code here

幫我做的第一步

你說錯了什麼？ – pskink

在「紋理」（無法實例化紋理類型）中，行：this.mTexture = new Texture（512,512，TextureOptions.BILINEAR_PREMULTIPLYALPHA）; –

也許您正在使用尺寸大於紋理中提及的寬度和高度的圖像。檢查圖像的寬度和高度，嘗試增加紋理的寬度和高度，並檢查是否正常工作 OR 試試你的紋理改變BitmapTextureAtlas和嘗試這個

私人BitmapTextureAtlas mtexture; private TextureRegion mregion;

mtexture = new BitmapTextureAtlas(1024, 512, TextureOptions.BILINEAR_PREMULTIPLYALPHA);  
mregion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(mtexture, getApplicationContext(), "Splashscreen.png",0,0); 
getEngine().getTextureManager().loadTexture(mtexture);

首先，改變GLES2 - 中心定位，如果你還處於起步階段。

然後：

mTexture = new BitmapTextureAtlas(getTextureManager(), 256, 256, TextureOptions.DEFAULT); 
mSplashTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(yourTexture, this, "gfx/Splashscreen.png"", 0, 0); 
mTexture.load();

然後：

最終的Sprite飛濺=新的Sprite（的centerX，centerY，this.mSplashTextureRegion，mEngine.getVertexBufferObjectManager（））; scene.getLastChild（）。attachChild（splash）;

爲什麼你將它附加到最後一個子實體？
