Detecting touch on specific part of the skeleton

[aliHafizji]

I just started using Spine and ran into a few issues. I'm using cocos2d as my game engine.

• Is there a way to detect touch on a specific part of the skeleton. For eg: If I wanted to detect if the touch was only on the torso or the head. How would I go about doing that?
• Also is there a way to change the texture that is drawn on a bone at runtime. For eg If the user touches the torse change the texture to something else?

You can use RegionAttachment_updateQuad to get the vertices for a region attachment. You can then use a polygon-contains-point algorithm to determine if a point is inside the region attachment. You can iterate the slots on a skeleton or use the Skeleton_getAttachment* functions to get the region attachments. See CCSkeleton draw().

You can change the attachment using Skeleton_setAttachment.

FWIW, the forums are a better place for questions. :) The issue tracker is better for bugs and feature enhancements.
