Question

在Java（Android）中，libgdx在触摸时绘制/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，它只会将动画渲染一秒钟。

   //@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（..）启用循环动画是否循环。设置为true。为什么不使用animation.getKeyFrame(stateTime)代替animation.getKeyFrame (float stateTime, boolean looping)。确保循环Animation.PlayMode。

 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));
     }

Answer 2

@AbhishekAryan谢谢先生，我得到了答案

 timePassed += Gdx.graphics.getDeltaTime();
    if(Gdx.input.justTouched() || touch==true){
        touch=true;
        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));
            if(animation.getKeyFrameIndex(timePassed) == 18){
                touch=false;
                timePassed=0;
            }
    }
    else if(touch == false){
        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));
       }

在Java（Android）中libgdx只需触摸即可绘制/渲染动画
