@brief
|
|
Using this type of delegate results in two benefits:
|
|
- 1. You don't need to deal with CCSets, the dispatcher does the job of splitting
|
|
them. You get exactly one UITouch per call.
|
|
- 2. You can *claim* a UITouch by returning YES in ccTouchBegan. Updates of claimed
|
|
touches are sent only to the delegate(s) that claimed them. So if you get a move/
|
|
ended/canceled update you're sure it's your touch. This frees you from doing a
|
|
lot of checks when doing multi-touch.
|
|
|
|
(The name TargetedTouchDelegate relates to updates "targeting" their specific
|
|
handler, without bothering the other handlers.)
