Ok, added this mainly to stop using my fork and to try to use rapier default in godot-rapier. This way I hope to no longer need to maintain that and use this repo as it is. (if this gets merged) |

Fixed the doc test from CI. |

Should it be max(0.0) ?

(outside of this PR's scope) @sebcrozet why does this function takes u8 rather than CoefficientCombineRule ?

I think there is some use-case for this in godot but that would be worth clarifying by @Ughuuu.

I don’t think there is a particular reason for this.

Not sure about the godot use case, this is just the exact code they have right now, so for parity I have that. Their use case is that they also have negative coefficients, and use this with absorbent field.

Then they do abs here, so the negative one becomes positive:

Should i add a comment in code around that match explaining that the coefficient can be negative in some cases?

Yes ; you can add a link to this discussion so the reader knows where this comes from 👍
Godot documentation for rough and absorbent is also relevant: https://docs.godotengine.org/en/stable/classes/class_physicsmaterial.html#class-physicsmaterial

Thank you for this PR. Just a couple of clarifications needed and it’s good to go.
(Sorry for the delay for reviewing this.)
