I have created a site where users are able to scroll through a gallery using mouse scroll or arrow up/down. It is working like I want it to, and changing one image pr scroll
I ran into a similar problem with a "section-change" plugin that I created. I ended resolving it with an "animation" variable: the wheel action only works if this variable is set to 'false' and once this is triggered the variable switches to 'true', then I would switch the variable back to 'false' once the animation is completed. Hope this helps!
