SFML三维鼠标簿

第2版：我解决了大部分问题，但有一点让我很烦恼。当光标到达屏幕边缘并被拉到另一侧时，相机会抖动，这将不起作用。有人能看到如何阻止这种情况吗？

    bool attention = true;
    Vector2 p, mousePos;
    private float MOUSE_SENSITIVITY = 4.0f;
    private void OnMouseMove(object sender, MouseMoveEventArgs e)

        float DeltX = 0, DeltY = 0;
        int border = 2;
        Console.WriteLine(attention + "");
        if (attention == true)
        {
            p.X = e.X;
            p.Y = e.Y;
            DeltX = (float)(mousePos.X - e.X) / MOUSE_SENSITIVITY;
            DeltY = (float)(mousePos.Y - e.Y) / MOUSE_SENSITIVITY;
        }
        else
        {
            mousePos = p;
        }
        attention = true;

            attention = false;

        }

        Cam.RotateY(DeltX);
        Cam.RotateX(DeltY);

        mousePos = p;
    }
