Question

我的游戏中有两个滑块，它们分别旋转和缩放+定位玩家精灵。

左滑块旋转精灵和正确的比例+以一定的速度移动玩家

我已添加了MultiTouch扩展程序

问题在于;

当我首先触摸左滑块（先旋转）然后触摸第二个（即右滑块）时，一切都很完美。但是，当我先触摸右侧滑块，然后触摸左侧时，会发生旋转，但是在视觉上看不到旋转。

可能是什么问题？如果需要，请分享代码

ONAREATOUCHED的旋转滑动代码

    @Override
   public boolean onAreaTouched(TouchEvent touchEvent,float pTouchAreaLocalX,float pTouchAreaLocalY) {

        mPlayer.clearRotationModifiers();
        float currentRotationValue;

        if(touchEvent.isActionDown())
        {

            //gesture detector enabled for rotation slider only
            mGestureDetector.onTouchEvent(touchEvent.getMotionEvent());

            this.LastPositionTouched=touchEvent.getMotionEvent().getY();
            currentRotationValue=this.CalculateCurrentCalibratedValue(pTouchAreaLocalY);



            mPlayer.MakeRotation(currentRotationValue);
            mPlayer.pressedPlayerActionOnRotation=1; //press started
        }
        if( touchEvent.isActionMove() )
        {


            this.DistanceConveredSinceLastDownEvent=touchEvent.getMotionEvent().getY()-this.LastPositionTouched;

            if( Math.abs(this.DistanceConveredSinceLastDownEvent) > HUDBar.minScrollDistanceCovered ){

                    mPlayer.pressedPlayerActionOnRotation=1;
                    currentRotationValue=this.CalculateCurrentCalibratedValue(pTouchAreaLocalY);                                
                    mPlayer.MakeRotation(currentRotationValue);
                }
            this.LastPositionTouched=touchEvent.getMotionEvent().getY();

        }
        if(touchEvent.isActionUp())
        {
            this.LastPositionTouched=0;
            MainActivity.this.mPlayer.pressedPlayerActionOnRotation=0; //pressing stopped
            mPlayer.resetRotation(-90); 
            //----reset debug variables-----
        }
        return true;
    }
};

我正在使用GestureListener的onLongPress for Rotation Slider并为深度滑块编写自定义onLOngPress，因为手势监听器不支持MultiTouch。我在玩家精灵上执行onLongPress，OnScroll事件

我找到了解决问题的方法

我正在清除touchevent上的所有先前的旋转修改器

我仅在有效事件上清除了旋转修改器。它开始工作。

也许对其他人也有用。

AndEngine：旋转修改器在MultiTouch中无法用于第二根手指
