Touch Gestures?

I need to detect gestures on the "Controls" layer that overlays all other layers but I do not really know how to go about this, I am not using the new touch dispatcher yet but even so I have looked at the example and I do not see how that would give me gesture control. Basically there are objects that can be touched in the layer below the "Controls" layer, but the gesture should take priority and the touch should be ignored if a gesture is done instead.

Does anyone have any experience doing this?

So I know I can use touchBegan and touchEnded and compare the values to see which direction the finger was dragged but isn't this supported natively?

Thanks!

See the tests/TouchTest/ example, in particular the Paddle.m file.

Or see the cocos2d/menu.m file.

They are using the new touch dispatcher. It supports priority.

eg:
```
[[TouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:0 swallowsTouches:YES];
```

I looked at those demo's but I am unclear on what problem it is solving? I am sure it is clear what problem it is solving to seasoned cocos2d developers but I have only been using it for a month. Also I didn't see anything for detecting gesture movements?

Thanks! :)

i think Riq answered to this (about prioruty):

Basically there are objects that can be touched in the layer below the "Controls" layer, but the gesture should take priority and the touch should be ignored if a gesture is done instead.

As for the gestures, you have to do what you said before: "use touchBegan and touchEnded and compare the values to see which direction the finger was dragged" for something simple.
