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

I have my algorithms & data structures course (including geometry algorithms) semester ahead, so I don't know. I'd probably be able to do something with rectangles, but no physics.

[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.

[Alzter]

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.

Do you really think priority urgent is necessary here?

[Rusty-Box]

Not anymore really. While I'd still consider it urgend to have it for stuff like swimming and, which has rotating sprites, we have functional alternative for the time being. So yes and no.

[tobbi]

Better?

Tbh i feel like swimming with a rotating hitbox would be very annoying.

Don't know how since the hitbox will match Tux's actual sprite so it is even more predicatable when you get hit or not

I guess for me it depends how Tux reacts when he turns around and his hitbox crashes into a wall.
