 public float speed = 6.0F;    public float jumpSpeed = 8.0F;    public float gravity = 20.0F;    private Vector3 moveDirection = Vector3.zero;

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

上面是官方給出的例子，由於檢測移動是只能在地面上才能用，所以要將檢測移動的代碼移出至判定外。 但是將判定位移移出後Y軸將會一直為0，所以需要定義一個變數用來計算當前Y軸方向速度。

 

修改後代碼：

 

 public float speed = 6.0F;    public float jumpSpeed = 8.0F;    public float gravity = 20.0F;
　　 public float verVel  = 0;                    //vertical velocity    private Vector3 moveDirection = Vector3.zero;

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

 　　　　 moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
　　　　  moveDirection = transform.TransformDirection(moveDirection);
        moveDirection *= speed;
        if (controller.isGrounded) {        　　if (Input.GetButton("Jump"))               moveDirection.y = jumpSpeed;                    }
        verVel = -= gravity * Time.deltaTime;        moveDirection.y = verVel;        controller.Move(moveDirection * Time.deltaTime);    }
