Cocos2d-x genie collision detection (method 2)

Change the UPDATE function of "Cocos2d-x sprite collision detection (method 1.

Use the sprite boundingbox function to obtain the direct sprite boundbox. You do not need to calculate the size of the sprite rectangle by yourself. It is also more precise than the limit. Then, call intersectsrect to calculate whether there is an intersection between the two sprite rectangles.

Code:

Void helloworld: Update (float delta) {// return to the sprite border box ccrect CR1 = SP1-> boundingbox (); ccrect Cr2 = SP2-> boundingbox (); if (cr1.intersectsrect (CR2) // whether there is an intersection {cclog ("is conllision... ");} elsecclog (" is't conllision... ");}
