Player falling through the floor
I have started a new Unity project and created a player with PlayerController script.
When I hit play, my player starts falling through the floor and after a few seconds it teleports up, to where it started falling. The floor, has a box collider and my player has a capsule collider and a rigidbody (both colliders have the isTrigger boolean set to false and they are both in the Default layer). I am using the same controller script I always use in my projects (unless I made a mistake and can't find it).
Here's that script:
public class PlayerController : MonoBehaviour
{
public Rigidbody playerRigidbody;
public Camera playerCamera;
public float speed = 3f;
public float mouseSensitivity = 5f;
public Vector3 cameraOffset = Vector3.zero;
private Vector3 playerPosition = Vector3.zero;
private Vector3 playerRotation = Vector3.zero;
private Vector3 cameraRotation = Vector3.zero;
void Start()
{
playerRigidbody = GetComponent<Rigidbody>();
playerPosition = playerRigidbody.position;
playerRotation = playerRigidbody.rotation.eulerAngles;
cameraRotation = playerCamera.transform.localEulerAngles;
}
void Update()
{
CalculateMovement();
playerCamera.transform.position = playerRigidbody.position + cameraOffset;
}
void FixedUpdate()
{
playerRigidbody.MovePosition(playerPosition);
playerRigidbody.MoveRotation(Quaternion.Euler(playerRotation));
playerCamera.transform.localEulerAngles = cameraRotation;
}
void CalculateMovement()
{
Vector3 xVel = transform.right * Input.GetAxis("Horizontal");
Vector3 zVel = transform.forward * Input.GetAxis("Vertical");
playerPosition += (xVel + zVel) * speed * Time.fixedDeltaTime;
Debug.Log((xVel + zVel) * speed * Time.fixedDeltaTime);
float xRot = -Input.GetAxis("Mouse Y");
float yRot = Input.GetAxis("Mouse X");
playerRotation += new Vector3(0f, yRot, 0f) * mouseSensitivity;
cameraRotation += new Vector3(xRot, yRot, 0f) * mouseSensitivity;
}
}
As you can see I've included a Debug.Log(), but it always prints 0.0 on the y axis.
EDIT:
I have removed the PlayerCotroller and the falling is not happening anymore, so there's something wrong with it.
I would be very happy if you'd help me find the error.
The slow movement downward was due to gravity, but it wasn't able to build up since you were using moveposition each frame without accounting for it. I prefer just setting the rigidbody.velocity directly. Hope this helps.

cameraRotation += new Vector3(xRot, yRot, 0f) * mouseSensitivity;
}
void FixedUpdate() {
float yVel = playerRigidbody.velocity.y;
playerRigidbody.velocity = (xVel + zVel) * speed + Vector3.up * yVel;
playerRigidbody.MoveRotation(Quaternion.Euler(playerRotation));
playerCamera.transform.localEulerAngles = cameraRotation;
}
}
