I was reading the programming guide about touches. I saw that there are 2 different kinds. The game i want to make will probably use multi touching. The standard touch delegate is what I would use right? Where can i learn more in depth about it? I was at this page.

Look up UITouch in the Apple documentation for further information on touches.

Can you use UITouch with cocos2d?

Posted 1 year ago #

The methods cocos2d provides in the protocol pass a UITouch object as one of the parameters. I suggest looking at some example projects to see how touches are handled in a cocos2d application. It's not hard once you see how it works.

- (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event;
- (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event;
- (void)ccTouchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event;

Example

-(id)init
{
        if(self=[super init])
        {
            //Layer responds to touches
            self.isTouchEnabled = YES;
        }
        return self;
}

-(void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
        //One single touch
	UITouch *touch = [touches anyObject];

        //All active touches
        NSArray *touches = [touches allObjects];

        //The point at which a touch is within a view.
	CGPoint point = [touch locationInView: [touch view]];
}
