Rotating hitboxes [HELP WANTED!]

[Rusty-Box]

Something that would be really benefitial is having rotateable hitboxes (for mechanics like swimming, swinging on ropes, rotating platforms etc.).

If you know how to do it in C++ we would be thankful for your help and support!

Ping to our known coders, in case one of you has some knowledge to share - @tobbi @HybridDog @Zwatotem

What about going straight for convex polygons? Since this is an occasion for changes, maybe do it right away, and not rise similar issue in a couple months? I mean, if you can't really predict any usecase for polygon hitboxes, then we'll stay with rectangles, but otherwise I think it's worth it.

@Zwatotem What would be the benefits we get through polygon hitboxes compared to rectangles?

[Zwatotem]

I think some larger creatures object like bosses could be better modeled. Although in most cases I can think of they would require concave polygons, some things (like a large snowball featured rarely in bonus levels) gain on this undoubtly.

Although in most cases I can think of they would require concave polygons […]

That's probably not a problem because often those concave polygons can be decomposed into smaller convex polygons.

A polygon could be used for this spike, but it would break backwards-compatibility. I'm sometimes wondering how it is possible to get hurt by this almost 60 degree spike.

Not strictly related to polygon hitboxes, but these single sided spike tiles will hurt you from any angle. You can jump and hit your head on the wood block part of this spike and it'll hit you. On top of this spikes aren't solid blocks which is odd.
