側面滾動雲彩

Question

我有從左到右滾動的雲層。我正在使用OrthographicCamera來做到這一點。我想知道，我將如何調整這些雲層以便讓它們朝着屏幕移動，而不是從左到右移動？我還可以使用Orthographic相機嗎？我將如何做到這一點？

我的代碼如下：

public void create() { 

     sky = new SkyFlux(); 

     //getting the height and width for setup purposes 
     float w = Gdx.graphics.getWidth(); 
     float h = Gdx.graphics.getHeight(); 

     //setting up camera and batch 
     camera = new OrthographicCamera(1, h/w); 

     //setting up sky 
     for(Texture texture:sky.getTexture()) 
      textures.add(texture); 

     //Adding the sky related sprites 
     for(Sprite sprite:sky.getSprite()) 
      skySprites.add(sprite); 
} 



public void render() { 

     //clearing everything out 
     Gdx.gl.glClearColor(1, 1, 1, 1); 
     Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT); 
     time += Gdx.graphics.getDeltaTime(); 
     if(time > 1.0f) 
      time = 0.0f; 

     float speed = 1.0f; 

     //Adjusting the speed of the sprites except the first sprite which is the base image. 
     for(int i=1;i<skySprites.size();i++) { 
      skySprites.get(i).setV(time+speed); 
      skySprites.get(i).setV2(time); 
      speed = speed+1.0f; 
     } 

     //setting up 
     batch.setProjectionMatrix(camera.combined); 

     //begging draw 
     batch.begin(); 

     //items to be drawn 
     //TODO: add other items to be drawn here 
     for(Sprite sprite:skySprites) 
      sprite.draw(batch); 


     //ending draw 
     batch.end(); 
}

正投影由定義的商店中沒有深度信息。你可以讓屏幕上出現雲彩的唯一方法是增加精靈尺寸 - 但我建議不要這樣做。

您應該使用非正交投影，並使用z軸。
