The _MOUSEWHEEL function returns an INTEGER value which can be negative or positive or 0.
Syntax: scroll% = _MOUSEWHEEL
- Positive values represent how many "clicks" the mouse wheel has been moved down.
- Negative values represent how many "clicks" the mouse wheel has been moved up.
- Return values are relative to the last time _MOUSEINPUT was used, so if no movement on the wheel has occurred since the last time, _MOUSEWHEEL returns 0.
