TGEA 1.03 Mounted Object Shadow Bug

#1 Interesting enough this has been a problem since back in TGE too.

What I have done is first check to see if the object is mounted to anything. If it is, do not render a shadow for that object as that object. That sounds confusing I know, let me explain. Each object is individually set to generate a shadow unless it is an shape image like a gun. Then it has its shadow generated when the object it is mounted to does. So what this first step does is just not generate the objects shadow yet.

Second I used a variation of the shape image shadow generation code to look for mounted objects in the normal seat nodes. I added a new variable to the shapebase code to allow you to only look in that area. Then I generate the objects shadow at the same time the main object and shape image shadows are being generated.

Here is my code. If you see anything wrong let me know.

In class ShapeBase : public GameBase right under the entry for MaxMountedImages, I added:

MaxMountedObjects = 4,  ///All other objects should be mounted images, only for mounted players in vehicles

Then right at the beginning of void ShapeBase::renderShadow(SceneState *state, RenderInst *ri), I added:

if(isMounted())
		return;

Finally, in void sgShadowProjector::sgRenderShadowBuffer(TSShapeInstance *shapeinstance) right after:

for(U32 i=0; i<ShapeBase::MaxMountedImages; i++)
	{
		TSShapeInstance *mountinst = shapebase->getImageShapeInstance(i);
		if(!mountinst)
			continue;

		MatrixF shapeworld;
		shapebase->getRenderImageTransform(i, &shapeworld);
		shapeworld.scale(sgParentObject->getScale());

		lightspace.mul(sgWorldToLightY, shapeworld);
      lightspace = shadowscale * lightspace;

		newmat.mul(proj, lightspace);
		sgRenderShape(mountinst, newmat, 0, newmat, -1);
	}

I added this:

for(U32 h=0; h<ShapeBase::MaxMountedObjects; h++)
	{
		ShapeBase *mountObj = shapebase->getMountedObject(h);
		TSShapeInstance *mountObject = dynamic_cast<TSShapeInstance *>(mountObj);
		if(!mountObject)
			continue;

		MatrixF shapeObjworld;
		mountObj->getRenderTransform();
		shapeObjworld.scale(sgParentObject->getScale());

		lightspace.mul(sgWorldToLightY, shapeObjworld);
		lightspace = shadowscale * lightspace;

		newmat.mul(proj, lightspace);
		sgRenderShape(mountObject, newmat, 0, newmat, -1);
	}
