Detect Touch in cocos2d-x V3.7?

Hi! So how to detect a touch in v3?
And why didn’t the developers just keep the old simple detection from v2? shouldnt that be very simple, like in v2?
Thanks!<#3
Btw, if u know something about OpenGL, please take a look at this: Went from V2 to V3.7 ported OpenGL code and got errors and questions now? Error: Failed to make complete framer buffer object 0x8CD9
Thanks again!
