java - 在 Java (Android) libgdx 中，触摸时绘制/渲染动画

Question

在 Java (Android) libgdx 中，当刚刚触摸时绘制/渲染动画，否则它将显示动画中的特定帧。问题是当我触摸屏幕时，它只会渲染一秒钟的动画。

   //@render   Spritebatch sb;

   if(Gdx.input.justTouched()){
        sb.draw((Texture) animation.getKeyFrame(timePassed,true), Gdx.graphics.getWidth() * 0.03f, Gdx.graphics.getHeight() * 0.03f, (Gdx.graphics.getWidth() * 1 / 6), (Gdx.graphics.getHeight() / 2) + (Gdx.graphics.getHeight() * 0.13f));
    }

    else{
        sb.draw(shot[1], Gdx.graphics.getWidth() * 0.03f, Gdx.graphics.getHeight() * 0.03f, (Gdx.graphics.getWidth() * 1 / 6), (Gdx.graphics.getHeight() / 2) + (Gdx.graphics.getHeight() * 0.13f));
    }

Answer 1

第二个参数 getKeyFrame(..) 启用循环，无论动画是否循环。设定为真。为什么不使用animation.getKeyFrame(stateTime)而不是animation.getKeyFrame(float stateTime, booleanlooping)。确保 Animation.PlayMode 已循环。

 if(!Gdx.input.justTouched()){
         sb.draw(shot[1], Gdx.graphics.getWidth() * 0.03f, Gdx.graphics.getHeight() * 0.03f, (Gdx.graphics.getWidth() * 1 / 6), (Gdx.graphics.getHeight() / 2) + (Gdx.graphics.getHeight() * 0.13f));
 }
 else{
       sb.draw((Texture) animation.getKeyFrame(timePassed,true), Gdx.graphics.getWidth() * 0.03f, Gdx.graphics.getHeight() * 0.03f, (Gdx.graphics.getWidth() * 1 / 6), (Gdx.graphics.getHeight() / 2) + (Gdx.graphics.getHeight() * 0.13f));
     }
