Mouse.WheelDelta will never be zero if the wheel was used ones. After that the value is 1 or -1. I think the WheelDelta should be reseted when the mouse wheel isn't used, so it's value is 0, instead of 1 or -1.
And how can I test if no mouse button is pressed? I am searching for something like
!Mouse.Pressed. At the moment I need to test if every button is not pressed:
!Mouse[MouseButton.Left] && !Mouse[MouseButton.Right] .... Or Am I missing something?
