Looking up Terrain material

#1 The following is what I use for projectile damage by material where rInfo has information on whatever the projectile has just collided with:-

TerrainBlock* tBlock = static_cast<TerrainBlock*>(rInfo.object);

               
S32 mapIndex = tBlock->getTerrainMapIndex(rInfo.point);
if (mapIndex != -1) 
   {
   MaterialPropertyMap* pMatMap = static_cast<MaterialPropertyMap*>(Sim::findObject("MaterialPropertyMap"));
   const MaterialPropertyMap::MapEntry* pEntry = pMatMap->getMapEntryFromIndex(mapIndex);
   if(pEntry)
      {
          mMaterialHitType = pEntry->matType;
          mMaterialHitFlags = pEntry->matFlags;
      }
   }

mMaterialHitType and mMaterialHitFlags are my own additions but the method to get the information should be apparent

#2 Ok, I tried to incorporate the code to fit my need, but the pEntry->matType and pEntry->matFlags are always the same.

TerrainBlock* tBlock = static_cast<TerrainBlock*>(wheel->surface.object);               

S32 mapIndex = tBlock->getTerrainMapIndex(wheel->data->pos);
if (mapIndex != -1)
	{   
	MaterialPropertyMap* pMatMap = static_cast<MaterialPropertyMap*>(Sim::findObject("MaterialPropertyMap"));
	const MaterialPropertyMap::MapEntry* pEntry = pMatMap->getMapEntryFromIndex(mapIndex);   
	if(pEntry)      
	{          
	 	mMaterialHitType = pEntry->matType;          
		mMaterialHitFlags = pEntry->matFlags;      
	}   
}

Can I do like this or do I have to use the rInfo?

I found a part in wheeledVehicle.cc, the part under RayInfo rInfo; which I logged and it also returns the same
value wherever I go: (rInfo.material = 3.43597e+0C)


Actually, the stock code seems to support what I am looking for by looking at the comments, but it always finds the default value.
This is found im wheeledVehicle.cc:

TerrainBlock* tBlock = static_cast<TerrainBlock*>(wheel->surface.object);
          S32 mapIndex = tBlock->mMPMIndex[0];
			
            // Override the dust color with the material property
            const MaterialPropertyMap::MapEntry* pEntry;
            if (matMap && mapIndex != -1 &&
                  (pEntry = matMap->getMapEntryFromIndex(mapIndex)) != 0)

Also, I checked the code in player.cc which tries to set the color for footpuffs, but the puffs are always the same color because useEmitterColors = false in the player.cs. If set to true, particles gets white and totally opaque.

In my last attempt I at least managed to read the color values from the propertyMap.cs.
I suspect there is something else to be done to be able to read/update the materials.

This tread seems to very interesting, but didn't give me an exact answer to my problem.

Any ideas? Anything script-related maybe?

#3 There is fixes for both vehicles and the player search the forum a little more !

#4 Yes, this "fix" sounds like the remedy to me. Not sure why it should be a fix, it's in the engine and should work right off...
Have I had better C++ skills I wouldn't have to dig around GG forums this much.
Gues I'll have to do some more diggin'.

Keyword suggestions anyone?
Tried these: particles, material, texture, terrain, color, emitter, index

This thread sounds like the way to go:

I'ts a bit more work than I expected, but it would be good to have it working. The implementation of the original code seems be non-working and there doesn't seem to be a quick fix to repair it...
I was kind of hoping for "change this line in xx.cc and then this line in yy.cc and you're set".

@Bill L
Where the threads you saw the "quick fix"-type or more an explanation of what to look for?

#6 Now THIS looks promising!
Seems like I will get my hinds dirty tonight!
Thanks Billy L!
