Requesting groupIndex support for Box2D

As my game needs more than 16 different "collision types" I need to be able to use the groupIndex option that Box2D offers.

In return I will use a nice little OBEY Avatar. What do you say? :)

I thought the shapedata was (possibly) unique for each shape?

So you do this:

Code: Select all

    circle_shape:setData("Ball") -- Set a string userdata 
    world:setCallback(collision) 
then have this:

Code: Select all

 function collision(a, b, c) 
     if a == "Ball" then
         -- do something
     end
     if b == "Ball" then
         -- do something
     end
 end

counterfactual_jones: It's not about shapedata.
Take a look at 6.2.3. Filtering in the box2D manual for a description. :)

rude: What did you add? The support? The request to a todo? Tell me. :roll:
