 == Terrain Collision
 
-This tutorial expands the HelloTerrain tutorial and makes the terrain solid. You combine what you learned in <<jme3/beginner/hello_terrain#,Hello Terrain>> and <<jme3/beginner/hello_collision#,Hello Collision>> and add a CollisionShape to the terrain. The terrain's CollisionShape lets the first-person player (who is also a CollisionShape) collide with the terrain, i.e. walk on it and stand on it.
