libgdx不工作

Question

My animation is not working 2D动画，仅显示静态图片。我根据libgdx/wiki的例子做了一切。为什么它不起作用？

public class Thorns extends GameObject implements IGameObject { 

    Animation<TextureRegion> animation; 
    private static final int FRAME_COLS = 1, FRAME_ROWS = 2; 
    public Thorns(Texture texture, Body body) { 
     super(texture, body,false); 
     Texture walkSheet = new Texture("Thorns.png"); 
     TextureRegion[][] tmp = TextureRegion.split(walkSheet, 
      walkSheet.getWidth()/FRAME_COLS, 
      walkSheet.getHeight()/FRAME_ROWS); 

     TextureRegion[] walkFrames = new TextureRegion[FRAME_ROWS*FRAME_COLS]; 
     int index = 0; 
     for (int i = 0; i < FRAME_ROWS; i++) { 
      for (int j = 0; j < FRAME_COLS; j++) { 
       walkFrames[index++] = tmp[i][j]; 
      } 
     } 

     animation = new Animation<TextureRegion>(1.025f, walkFrames); 
    } 

    @Override 
    public void dispose() { 

    } 

    int stateTime; 

    @Override 
    public void draw(SpriteBatch spriteBatch) { 
     stateTime += Gdx.graphics.getDeltaTime(); 

     TextureRegion currentFrame = (TextureRegion) animation.getKeyFrame(stateTime, false); 

     spriteBatch.draw(currentFrame, body.getTransform().getPosition().x, body.getTransform().getPosition().y); 
     //drawSprite(spriteBatch); 

    } 
} 

动画不启动在所有

完全可能的动画正在运行，但你没有得到他的观点，因为你已经与帧持续时间1.025 sec两种帧动画。而你的动画运行无环。

尝试环Aniamation以便传递true如getKeyFrame (float stateTime, boolean looping)方法的第二个参数。

@Override 
public void draw(SpriteBatch spriteBatch) { 
    stateTime += Gdx.graphics.getDeltaTime(); 
    TextureRegion currentFrame = animation.getKeyFrame(stateTime, true); 
    spriteBatch.draw(currentFrame, body.getTransform().getPosition().x, body.getTransform().getPosition().y); 
} 

EDIT

变更数据的stateTime到float从int类型。
