Object with Character Controller falls through ground.

Question

I'm currently working on controls atm, and I have my object with a cc and my script (no rigid body). Every time I run it, however, the character just falls through the floor. The gravity is handled in the script. I have tried adding rigid bodies to the floor, the character, tried adding separate colliders, etc. and nothing works. Here is my code in case it helps. And no, none of the colliders on the floors are triggers.

 using UnityEngine;
 using System.Collections;

 public class CharacterController : MonoBehaviour {


 float mouseVertical = 0f;
 float vertVelocity = 0f;
 [SerializeField]
 float speed;

 [SerializeField]
 float sensitivity;

 [SerializeField]
 GameObject cam;

 CharacterController cc;

 // Use this for initialization
 void Start () {
     cc = GetComponent<CharacterController>();
     
 }
 
 // Update is called once per frame
 void Update () {
     moving();
     cameraController();
 }

 void moving()
 {
     float mouseHorizontal = Input.GetAxis("Mouse X");

     cc.transform.Rotate(0, mouseHorizontal*sensitivity, 0);

     float moveZ = Input.GetAxis("Vertical");
     float moveX= Input.GetAxis("Horizontal");

     vertVelocity += Physics.gravity.y * Time.deltaTime;

     Vector3 movement = new Vector3(moveX* speed, vertVelocity, moveZ * speed);

     cc.Move(movement * Time.deltaTime);

 }

 void cameraController()
 {
     mouseVertical -= Input.GetAxis("Mouse Y") * sensitivity;

     mouseVertical = Mathf.Clamp(mouseVertical, -90, 80);

     cam.transform.localRotation = Quaternion.Euler(mouseVertical, 0, 0);

     Debug.Log(cam.transform.rotation.x);
 }

}

I had the same problem, I had to use SimpleMove, instead of just Move, and actualy set it always moving, but with a speed of 0. but yes you need a rigidbody and character controller 'capsule' thing. And make sure capsule is just above floor just a tad.

A.) I know that the Character Controller collider is not starting in the floor. It is well above it. B.) I have already tried putting a Rigidbody on it, nothing happens.

Try putting this in the object:

 Vector3 move = new Vector3 (0, 0, 0); 
 gameObject.Simple$$anonymous$$ove (move * speed);

I know it sounds stupid, but just paste this in your update() and see if stops falling

You need to cancel your vertical velocity when your character controller collides below with the ground. Currently your vertical velocity is increasing without any condition and any limit. So even when you hit the ground and may be stopped for a sec. the velocity gets bigger and bigger until you simply teleport through the ground.

The Move method returns a CollisionFlags value to indicate where it collided.

There's a problem with rigidbody + character controller and using $$anonymous$$ove. Simple$$anonymous$$ove has to be called. $$anonymous$$y code doesn't call velocity at all, it only called $$anonymous$$ove, and character fell through floor every time. I threw in the Simple$$anonymous$$ove, and everything worked fine. :)
