在Java（Android）中libgdx只需觸摸即可繪制/渲染動畫

Question

在Java（Android）libgdx繪制/渲染動畫時，只需觸摸它，它將顯示動畫中的特定幀。 問題是，當我觸摸屏幕時，它只會將動畫渲染一秒鍾。

   //@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

第二個參數getKeyFrame（..）啟用循環動畫​​是否循環。 設置為true。 為什么不使用animation.getKeyFrame(stateTime)而不是animation.getKeyFrame (float stateTime, boolean looping) 。 確保使用Animation.PlayMode循環。

 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謝謝先生，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));
       }
