Hi all,
I’m reading the physics.addBody() function in the Docs and it states:
“Each body element may have its own physical properties, and the body element index is reported as part of each collision event – so it is possible to detect which part of a complex body was involved in a collision.”
What code do we use to return the Body Element Index of a complex body during a collision for example?
Cheers,

For anyone looking for a solution to this, I found that event.otherElement (likewise event.selfElement) will return number which is the index of the bodies on the collided object.
Perhaps I was reading the documentation wrong, but it stated this the code would be event.element1, event.element2 here: http://docs.coronalabs.com/api/event/collision/element1.html
API perhaps needs updating?
I hope this helps.

Hi Michael,
I looked at the docs, and it appears that the notation varies depending if you’re using a global (Runtime) collision listener, or local (table) collision listeners attached to each object. The Runtime method uses the “element1/element2” event, and the local method uses the “selfElement/otherElement” event.
If you find that this is otherwise (not true), please let me know and I’ll investigate if the docs need to be changed.
Thanks!

Hi Brent,
Thanks for the reply. You’re absolutely right. Runtime collision events use event.element1 / event.element2, and local (table) collision listeners use event.selfElement / event.otherElement listeners to return the objects index number. Perhaps I miss understood the short explanation under the Overview paragraph.
Nevertheless, figured it out. Hope this helps others in the right direction.
