During a recent rewrite of the menu system, it occurred to me it would be nice to have a visual preview of the various animation easing curves available in the engine.

So I made a tool to do that. Pick an easing function, see the curve and an animation showing its effect on alpha, scale and position. 20 minutes, 150 lines of code.

This will make it much easier to pick the right function when creating new UI and in-game animations.

Luckily I’m done with the menus for now. If I ever need to add more polish, I might attach this new interface directly to the actual element being animated. That would make this a real WYSIWYG tool.
