LWJGL 2 Mouse doesnt give out dx/dy when grabbed

I currently am making a game with a FPS type interface. Mouse.setGrabbed(true) and i'm trying to use that but now Mouse.getDX() and Mouse.getDY() does not work anymore and return 0. How can I get the values while the mouse is grabbed?

Solution

  • According to the LWJGL 2 documentation, when grab is true, getX() and getY() will return the delta coordinate values for the mouse.
