Using the GMK with the BG Cliff Kit

This for those of you that own both the GMK and are using the Physics pack and also own the BG Cliff Kit. You have probably noticed the new physics objects do not react to the cliffs. Here is a couple of small changes to each to make it all work. Yes, I asked both Yuri and Konrad Kiss for permission to release this.

Lets start with the GMK code.
In tsSTatic.h at the bottom where you added the other code for the Physics Pack right after

Vector<U32> mIndexBuffer;

add:

void prepGMKCollision();

Now in tsStatic.cpp at about line 125, change all of this:

//.logicking >> 
   //create physic object
   Physics* physics = Physics::getPhysics(isServerObject());
   if(physics)
   {
	   mPhysPolyList = new ConcretePolyList();
	   Box3F box = getWorldBox();
	   bool res =  buildPolyList(mPhysPolyList, box, SphereF());

	   if(res && mPhysPolyList->mPolyList.size()>0)
	   {
		   for(U32 i = 0; i < mPhysPolyList->mPolyList.size() ; i++)
		   {
			   ConcretePolyList::Poly& poly = mPhysPolyList->mPolyList[i];
			   for (int i = 0;i<poly.vertexCount-2;i++)
			   {
				   mIndexBuffer.push_back(mPhysPolyList->mIndexList[poly.vertexStart]);
				   mIndexBuffer.push_back(mPhysPolyList->mIndexList[poly.vertexStart+i+2]);
				   mIndexBuffer.push_back(mPhysPolyList->mIndexList[poly.vertexStart+i+1]);
			   }
		   }

		   Point3F* vBuffer = mPhysPolyList->mVertexList.address();
		   int  	vNum = mPhysPolyList->mVertexList.size();
		   U32*		iBuffer = mIndexBuffer.address();
		   int  	iNum = mIndexBuffer.size();

		   mPhysGeom = physics->createPhysShape(vBuffer, vNum, sizeof(Point3F), iBuffer, iNum,3*sizeof(U32));
	   }
   }
   //.logicking <<

   addToScene();

   return true;
}

to this:

prepGMKCollision();

   addToScene();

   return true;
}

void TSStatic::prepGMKCollision()
{
   //.logicking >> 
   //create physic object
   Physics* physics = Physics::getPhysics(isServerObject());
   if(physics)
   {
	   mPhysPolyList = new ConcretePolyList();
	   Box3F box = getWorldBox();
	   bool res =  buildPolyList(mPhysPolyList, box, SphereF());

	   if(res && mPhysPolyList->mPolyList.size()>0)
	   {
		   for(U32 i = 0; i < mPhysPolyList->mPolyList.size() ; i++)
		   {
			   ConcretePolyList::Poly& poly = mPhysPolyList->mPolyList[i];
			   for (int i = 0;i<poly.vertexCount-2;i++)
			   {
				   mIndexBuffer.push_back(mPhysPolyList->mIndexList[poly.vertexStart]);
				   mIndexBuffer.push_back(mPhysPolyList->mIndexList[poly.vertexStart+i+2]);
				   mIndexBuffer.push_back(mPhysPolyList->mIndexList[poly.vertexStart+i+1]);
			   }
		   }

		   Point3F* vBuffer = mPhysPolyList->mVertexList.address();
		   int  	vNum = mPhysPolyList->mVertexList.size();
		   U32*		iBuffer = mIndexBuffer.address();
		   int  	iNum = mIndexBuffer.size();

		   mPhysGeom = physics->createPhysShape(vBuffer, vNum, sizeof(Point3F), iBuffer, iNum,3*sizeof(U32));
	   }
   }
   //.logicking <<
}

OK now onto the additions for the Cliff Kit.
In fxBGCliffReplicator.cpp around line 693, right after:

mCurrentShapeCount = mReplicatedShapes.size();

add this:

for(U32 i = 0; i < mReplicatedShapes.size(); i++)
	{
		TSStatic * replicatedStatic = dynamic_cast<TSStatic*>(mReplicatedShapes[i]);
		if(replicatedStatic)
		{
			replicatedStatic->prepGMKCollision();
		}
	}

Then in tsBGCliffStatic.cpp around line 138, right after:

addToScene();

add this:

TSStatic * cliffStatic = dynamic_cast<TSStatic*>(this);
	if(cliffStatic)
	{
		cliffStatic->prepGMKCollision();
	}

You have to do both because if you choose to only make one cliff, or replicate the cliffs, makes a difference on which of those two additions will be needed.

Well that's it, pretty simple stuff but after doing a clean and compile you should see GMK Physics pack object collisions with BG Cliffs.
