contactCallback with any body

Hallo all,

I have the following problem:

When an enemy shoots an bullet and the bullet hits any body, then I need to play a sound and the bullet shall disappear. I have several types of Bodies like houses, trees, cases etc.
The long-winded way would be: set material pairs with bullet and houses, bullet and trees, bullet and cases. Then create the contactcallback(including userbegin, process etc) for each pair.
Now my question is: Is there a way to call one contactcallback, regardless of which body is collided with the bullet, so that I can play the sound and let the bullet dissapear.

thanks in advance.

Then use for all your bodys the same function for callback.

Hm, is there not an faster way? I have ca. 20 different body types and this means, that I have to spezify 20 material pairs; bullet with houses, bullet with trees and call the same contact callback function. But if there is no other possibility, then I'll do it that way.

thanks.

Maybe you can use a switch in your type of body and use the sound as you want for each body...

yeah, basically you could assign the same material to all of those if you wanted to and the same material pair,...then you could just check which bodies collided in the callback
