Finding out which Newton Bodies collided?

[EvilTwin]

So I'm trying to code a "Blockbreaker" with Irrlicht and Newton, and I wanted to know if there is any way to know which two bodies collided in NewtonContactProcess callback.
For more detail: I'm trying to code the functionality to actually "break" the blocks...

In teh callback

Code: Select all

void UserContactCallback (const NewtonJoint* contactJoint, dFloat timestep, int threadIndex)
{
   const NewtonBody* body0 = NewtonJointGetBody0(contactJoint);
   const NewtonBody* body1 = NewtonJointGetBody1(contactJoint);

...
}

Wow, thanks!
Have read that callback somewhere in this forum already, but when I tried to research on Newton Wiki, I did only find NewtonContactBegin and NewtonContactProcess... someone seriously needs to update the "api database"-link on the left side of the wiki so it doesn't point to deprecated functions anymore or at least includes the new ones... pretty hard for newcomers to get familiar with the engine if there's (appearently) only old functions shown... is there help needed on the wiki? because I would like to help with that stuff, reorganizing and stuff... would allow me to get to know the engine quite thoroughly, you know?

Yes create an account and correct pages, this is the purpose of a wiki.

Some page related to newtoncontectbegin is admittedly from times of 1.53 but most of wiki is up to date, but with some searching you would find this page:

Wiki is still being written we will sort it out. And as with all wikis you are welcome to add your findings, comments & remarks to pages and help working on it.
