I am currently working on my character's movement in Unity3D. I managed to make him move relatively to the mouse cursor. I set a slope limit of 45°, which does not allow the character to walk up the mountains with higher degrees. But he can still jump them up.

How do I manage to make him slide down again when he jumped at places with too high slope?

Thanks in advance.

edit: Code snippet of my basic movement. using UnityEngine; using System.Collections;

public class BasicMovement : MonoBehaviour {
    private float speed;
    private float jumpSpeed;
    private float gravity;
    private float slopeLimit;
    private Vector3 moveDirection = Vector3.zero;

    void Start() 
    {
        PlayerSettings settings = GetComponent<PlayerSettings>();
        speed = settings.GetSpeed();
        jumpSpeed = settings.GetJumpSpeed();
        gravity = settings.GetGravity();
        slopeLimit = settings.GetSlopeLimit();
    }

    void Update() {
        CharacterController controller = GetComponent<CharacterController>();
        controller.slopeLimit = slopeLimit;

        if (controller.isGrounded) {
            moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
            moveDirection = transform.TransformDirection(moveDirection);
            moveDirection *= speed;

            if (Input.GetButton("Jump")) {
                moveDirection.y = jumpSpeed;
            }

        }
        moveDirection.y -= gravity * Time.deltaTime;
        controller.Move(moveDirection * Time.deltaTime);
    }
}
