Is it possible to detect whether the mouse wheel is scroll up or down?
You can use the MouseWheelDelta() expression on native platform, it doesn’t work in HTML5.
To use it, just go to Other->Compare two expressions and enter
Expression 1
MouseWheelDelta()
Sign of test
Expression 2
enter 1 to check if mouse is scroll up or -1 to check if mouse is scroll down
Don’t use equal for that, just compare with 0 because it can be greater than 1 or less than -1.
I thought the expression return 1 and -1 only depends on the direction of scroll.
I mean I tried and doesn’t seem to effect how many times I scroll up or down the expression always returns 1 or -1
What am I missing?
EDIT://
Ah I see. I have just tried < 0 and > 0 and sometime it does return 2 and -2 but since every scroll is count, 99.9% of the times it end up with 1 and -1, so it should be not a problem unless you really do want to scroll the wheel only a single time each time
Thanks guys!
