How do I get input from the mouse wheel? For example, for zooming in an out of the map in a strategy game.
The "Wheel Up Button" in Input doesn't seem to work, unfortunately. My mouse scrolls smoothly with no buttons. I think what I need is an analog input rather than an on/off value.
I'm using Godot 3.0.5 and C# but it should be roughly the same for GDscript.
