Cocos2d-x genie listens to click events

Http://labs.easymobi.cn /? P = 5167

The implementation process implements the cctouchdelegate interface, adds a listener when entering, removes the listener when exit and destructor, and converts the touch coordinate to the relative sprite coordinate when you click, if it is within the genie range, the response will be clicked. I personally think it is too complicated to refer to the examples in the previous two articles. So it seems easier to understand it with a slight modification.

Pianotile. h
