CharacterControllerWaitForTerrainLoad script for those of you who do not use a rigid body but need a wait for terrain load script

[Cliff]

I don't use a rigidbody for my character controller as I use Game Creator 2 and mostly use the character controller for my player. I was running into issues where I needed a script to wait for the terrain to load, but using a character controller.

I'll share the script with those of you who may find it useful so you don't have to reinvent the wheel. I would have loved to find this script instead of taking the time to do it myself.

It seems to work for me, and hopefully it will for you too.

        void Start()

            if (TerrainLoaderManager.TerrainScenes.Count > 0)
            {
                m_watchedCharacterController = GetComponent<CharacterController>();

                // Find the relevant scene
                foreach (TerrainScene p in TerrainLoaderManager.TerrainScenes)
                {
                    if (p.m_bounds.Contains(transform.position))
                    {
                        m_terrainScene = p;

                    }
                }

                // No terrain scene found? Nothing to do then.
                if (m_terrainScene == null)
                {
                    Destroy(this);

                m_watchedCharacterController.enabled = false;
            }
            else
            {
