Use a circle for the ball in Breakout #4324
Description
Once #3730 is merged, we should represent the ball as a circle, rather than a square. We can probably stick with the AABB collision though for simplicity.

I have a feeling that in practice, not doing proper circle-aabb collision would end up looking pretty janky, but I'd personally love to see that if it doesn't complicate the example too much.

as a side note, this could already be done by using a round image, like https://github.com/bevyengine/bevy/blob/main/assets/branding/icon.png

#3730 is merged so this is now quite easy :)

I made a PR pretty much exactly the same as the #4682, if there is no answer from the creator of that PR, I can submit mine if you wish.

Yes please @galkowskit :) Just link to the other PR and we'll credit you both.

So the obvious collision "corner case" is this sort of thing:

We could
I have a slight preference for 2 but it seems like fixing the collision code would be sort of involved, so I suppose I don't really mind 1.

I think it also touches the physics issue. There is a very rudimentary code for reflections.

Hi, I'm trying to make a (modified) billiards game and need to detect to collision between balls. I was wondering if there already exists an implementation within bevy or whether I should make my own (and if its good/suitable enough I can contribute it back to bevy?). I've never contributed before so I'm not sure how this works. Thank you!

Bevy currently only has Axis Aligned Bounding Box for collisions, which probably wouldn't work very well for billiard
