\$\begingroup\$

In my cocos2d app I am trying to determine when a CCSprite is touched Here is what I have:

-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event{ NSMutableArray *targetsToDelete = [[NSMutableArray alloc] init]; for (CCSprite *target in _targets) { CGRect targetRect = CGRectMake(target.position.x - (target.contentSize.width/2), target.position.y - (target.contentSize.height/2), 27, 40); CGPoint touchLocation = [self convertTouchToNodeSpace:touch]; if (CGRectContainsPoint(targetRect, touchLocation)) { NSLog(@"Moo cheese!"); } } return YES; }

For some reason it does not work. Can someone help me?

  • \$\begingroup\$ try to rewrite this code using the syntax of objective-c. I do not write code to objective-c (write only in C + + and Java), I can only read it. mSprites is a vector whose elements are CCSprites. Try it, it should not be difficult. \$\endgroup\$ Commented Jul 7, 2012 at 16:03
