CharacterController makes player game object fall through generated terrain.
I have a player game object that uses CharacterController.
I generate my terrain from script when the scene is loaded (scene already has player game object)
Problem: Player GO falls through terrain while everything else stays on it.
other game objects with rigidbodies act as they should (colliding and bouncing on terrain, falling downhill slopes, etc.)
Every aspect of the terrain is complete, with a proper terrain collider and splatmaps/details. I also generate a navmesh and it works properly too (scripts generate stuff on random navmesh points, etc).
Further info:
The player GO is located where it is supposed to be, not intersecting the generated terrain's collider.
I tried both with player GO having a rigidbody ant not. (I know it's not supposed to have one anyway)
I tried in vain adding a capsule collider to a GO.
Player GO does not fall through the terrain if I have an existing terrain on the scene and modify it; instead of generating the asset in memory and adding it to the scene.
Can anyone give me some advice? I have searched all through and tried everything I could think of (short of changing the CharacterController with a RigidBody setup - which would be very, very, problematic at this point.)
I have debugged a lot more and came to the following conclusion: CharacterController does not collide with the generated terrain collider (`OnControllerColliderHit` is not called) but it collides with any pre-existing colliders in the scene (e.g. if I placed a plane under it). How can I get them to collide?
I figured this out, and in case anyone faces this issue, here is my fix/hack:
The problem was, for some reason, CharacterController did not register the TerrainCollider that I was creating through script. Since it was registering this if I used an existing terrain and modified it, it occurred to me that I should maybe try disabling and re-enabling the created TerrainCollider after I had finished with creating the terrain. It worked - CC now properly collides with TC and the player GO does not fall through. Simply:
_terrainCollider.enabled = false;
_terrainCollider.enabled = true;
Note that I believe this is a hack used as a workaround for a bug in the CharacterController. (or at least its integration with the TerrainCollider
