"""
Starting from step1, we just put an additional collision handler to take care to keep the avatar grounded. This will PUSH the avatar back as soon as hit geometry we settled to be a wall: in blender we modelled polygons to wrap around the little house and all around the terrain area so that this time the avatar, differently from step1, won't pass through the house and won't be able to leave the terrain perimeter anymore. I suggest you to open the blender source to find out what I'm talking about here.

#** This is our steering avatar - this time we use a little different setup, more close to real applications: we wrap either the avatar and its collision ray into another nodepath. This way we add lotta flexibility allowing us to make fancy things like you'll see below, to make the avatar rolling while steering, a thing not possible before and also to get rid of the global floorHandler.setOffset(1.0) shift, to set our avatar precisly placed above the surface.
