cocos2d-x C++
#1

Hey
i try to find the best way to do this effect when you Zoom in/out with 2 fingers
is there any way in cocos2d-x 3.3 to do this ? or i need to port it from some iOS solution ?
(i didn’t found any …)

Cocos2d-x doesn’t implement the this function, and you should implement it by yourself.

Note that:
1.Judge it is a multiple touch or a single touch.
2.Change the anchor point real-time.
3.Set scale range.

at last, don’t forget to enable iOS multiple touch support.

[eaglView  setMultipleTouchEnabled:YES];

There has been discussion regarding XTLayer.

We used a modified version of: https://github.com/imadeveloper/cocos2dx_extension

Notice that the core team is thinking about it.
