Mouse scrolling

Post by Eamonn »

Is it possible to add mouse scrolling in LÖVE? I don't believe I've ever seen it done, so I'm wondering if it's possible and how to do it?

How can I tell if the user is scrolling with the mouse wheel?

Thanks! :D

Sure, why not?

love.keypressed gets called every time your scroll wheel "clicks", with "wu" for up and "wd" for down.

Yes. Mousepressed, not Keypressed. It sends an event for every tick of the scroll. On OS X it even has the inertia.

Use the "wu" and "wd" as the buttons being clicked.

Hat Cat uses mouse scrolling for zooming in and out.

update? I think it works differently now. I set up a test to change the background color in love.mousepressed, and it doesn't trigger when I scroll my mouse wheel.

Yeah. 0.10.0 changed it to have its own callback. Also I think buttons are numbers now instead of letters for "l" and "r".

When in doubt, check the Wiki.
