在鼠标移动时隐藏和显示光标

Question

我希望在用户按下某个按钮时使鼠标不可见，而在用户移动鼠标时使光标可见。我已经完成了第一部分，但是我不知道如何跟踪鼠标的运动。我正在使用C＃。这是我的代码

void Update()
{


    if (characterController.isGrounded)
    {
        // We are grounded, so recalculate
        // move direction directly from axes
        moveDirection = new Vector2(Input.GetAxis("Horizontal"), 0.0f);
        moveDirection *= speed;

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

        if (Input.GetKey(KeyCode.W)) {
            moveDirection.y = jumpSpeed;
        }

        if (Input.GetKey(KeyCode.UpArrow)) {
            moveDirection.y = jumpSpeed;
        } else if (!characterController.isGrounded) {
            moveDirection.x = Input.GetAxis("Horizontal") * speed;
        }
    }

    if ((Input.GetKey(KeyCode.RightArrow) || Input.GetKey(KeyCode.LeftArrow) || Input.GetKey(KeyCode.D) || Input.GetKey(KeyCode.A) || Input.GetButton("Jump") || Input.GetKey(KeyCode.W) || Input.GetKey(KeyCode.UpArrow)) && Cursor.visible) {
        Cursor.visible = false;
    }


    // Apply gravity. Gravity is multiplied by deltaTime twice (once here, and once below
    // when the moveDirection is multiplied by deltaTime). This is because gravity should be applied
    // as an acceleration (ms^-2)
    moveDirection.y -= gravity * Time.deltaTime;

    // Move the controller
    characterController.Move(moveDirection * Time.deltaTime);

}
