我在游戏中有两个滑块，它们分别旋转和缩放播放器精灵的位置。AndEngine：旋转修饰符在MultiTouch中对于第二根手指不起作用
向左滑动旋转精灵 和右标+一些速度移动玩家
我已经包括了多点触控的扩展
的问题是;
当我先触摸左侧滑块（先旋转），然后再触摸右侧滑块时，一切正常。 但是，当我先触摸右侧滑块，然后再触摸左侧时，就会发生旋转，但旋转不会在视觉上看到。
可能是什么问题？ 如果需要生病份额代码
旋转滑块CODE FOR ONAREATOUCHED
@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;

};
DepthSlider代码使用GestureListener的onLongPress的旋转滑块
@Override
public boolean onAreaTouched(TouchEvent touchEvent,float pTouchAreaLocalX,float pTouchAreaLocalY)
{
float ScaleValue,StringLengthFactor,SpeedFactor;
//mPlayer.clearEntityModifiers();
if(touchEvent.isActionDown())
{
//for implementing custom longpress
this.isActionDownOccured=true;
//mPlayer.pressedTime=touchEvent.getMotionEvent().getEventTime();
this.initialTime=touchEvent.getMotionEvent().getDownTime();
this.pressedTime=this.initialTime;
/////////////////////////////////////////////
this.LastPositionTouched=touchEvent.getY();
//gesturedetector onDown motionevent passed in onLongPress
// mGestureDetector.onTouchEvent(touchEvent.getMotionEvent());
ScaleValue=this.CalculateCurrentCalibratedValue(pTouchAreaLocalY);
StringLengthFactor = ScaleValue * ScaleToStringLengthConversionFactor;
SpeedFactor = (ScaleValue>0) ? ScaleValue * ScaleToSpeedConversionFactor:0;
//---display local variables before set speed----------------
/*MainActivity.this.txtLoggingSpriteVariables.setText(
"TouchAreaLocalY: "+Float.toString(pTouchAreaLocalY)+
" Speed From:"+
Float.toString(MainActivity.this.mPlayer.getSpeed())+
" to: "+ Integer.toString(currentSpeedValue)
);
*/
mPlayer.setSpeedAndScaleInParallel(SpeedFactor, ScaleValue);
mPlayer.setDeltaStringLength(StringLengthFactor);
MainActivity.this.txtDepthLogger.setText("DepthSlider Down Event"+(MainActivity.this.MoveEventDepthSliderCount++)+"\n"+
"PointerCount "+touchEvent.getMotionEvent().getPointerCount()+" New Scale:" + mPlayer.getScaleX()+" \n " +
" New Speed: "+ mPlayer.getSpeed()
);
MainActivity.this.mPlayer.pressedPlayerActionOnDepth=1; //depth slider pressed
}
if(touchEvent.isActionMove())
{
this.DistanceConveredSinceLastDownEvent=touchEvent.getY()-this.LastPositionTouched;

IM和写定制onLOngPress深度滑块，因为手势监听器不支持MultiTouch。林表演onLongPress，对玩家精灵OnScroll事件
很难知道发生了什么事，却没有看你的代码，但你看过这个讨论吗？ http://www.andengine.org/forums/tutorials/problem-with-two-analog-sticks-t9567.html – 2013-02-19 00:01:51
是的，我读了那个链接。它与我的问题不同，即时设置场景中的HUD。不是现场的孩子。 – 2013-02-19 04:45:06
我已添加代码，请现在看看 – 2013-02-20 09:21:00
