MAterial Mapping

Can someone tell me how to access the material mapping functions from script so I can get material specific information upon collision?

There's no built-in support for that, but it's very easy to add in the C++ source if you have the need. Look at dgl/materialPropertyMap.cc.

Well I am almost totally successful in my code except for one very big problem. Shoot a bullet at anything but the terrain and it does exactly what it should. Shoot at the terrain and the game crashes. I now where the problem stems from but I am not sure why. In projectile.cc in the proccesstick function I added this right before the oncollision and explode call:

MaterialPropertyMap* pMatMap = static_cast(Sim::findObject("MaterialPropertyMap"));

const MaterialPropertyMap::MapEntry* pEntry = pMatMap->getMapEntryFromIndex(rInfo.material);

pMatType = pEntry->matType;

I know this has been used before in other places but I dont under stand why the use of either a static_cast or dynamic_cast towards a terrain object crashes my system. As I said before it works perfectly with every other object type.

Well I got past that point. I will likely look at releasing this after I knock out some more bugs.
