Materials problem

Postby Witek900 » Tue Jan 05, 2010 2:19 pm

I've created materials manager in my engine and it works OK. I can set collisions sound to each physics material etc. But now i want to make some materials no-collidable but i can't do this. I use NewtonOnAABBOverlap callback and return always 0, but all bodies still collide and dont have sounds, etc (made in NewtonContactsProcess). What's wrong? I also tried to disable all collisons by NewtonMaterialSetDefaultCollidable but it works exactly like with

NewtonOnAABBOverlap
{
return 0;
}

But for example NewtonMaterialSetDefaultElasticity ok.

It does not work. When apply this to each material pair:
Code: Select all
NewtonMaterialSetDefaultCollidable(NW, PhysicsMaterials[i]->GroupId, PhysicsMaterials[j]->GroupId, 0);

some materials collide and some no and collision callback doesn't work then.
Although,
Code: Select all
NewtonMaterialSetDefaultElasticity(NW, PhysicsMaterials[i]->GroupId, PhysicsMaterials[j]->GroupId, 1.0f);
works excelent.

Ha that may be, there are ton of Bugs in 2.15 because I build it with beta VS2010 and I made lots of refactoring according to VS recomendation and teh resutl is lot of bug.
mosutli because of VS do no liek Varible renaming and I use that a lot, su when I try to make fridnle to VS i added teh bugs.

Glad you foudn eth problem everyone should be in 2.16
