Improve 2 touches

Open VAdaihiep opened this issue 11 years ago • 5 comments

Hi growingdever, Thanks for your code, it's so cool. I think cocoa should add it in next version of Cocos2dx.

But it had a small issue: When touch 2 points NOT at the same time, the layer will be jerked.

I read your code and know the reason is: In ccTouchesMoved, prevPosTouch2 will not right if touch2 LATER than touch1.

The solution is:

  1. Add (after line 166 in PanZoomLayer.cpp): if (prevPosTouch2.x < 1 || prevPosTouch2.y < 1) { return; }
  2. Remove line if( _isHolding ) return; in ccTouchesEnded Then it works fine.

Please reply me if this modify have many negatively affected.
