There was a problem hiding this comment.
That condition should probably be in case there is no stairs ? otherwise we might end up intersecting with the stair. (and it might result in not going up the stair, or worse an infinite loop ?)
There was a problem hiding this comment.
indeed, but even with the reapply in the if !self.handle_stairs, reapplying the speed can be slightly flaky, especially in 3d
im turning the PR back into a draft and looking into it

reapply_lost_speed: boolto KinematicCharacterControllerWhen set to true, the velocity lost by sliding will be reapplied to the corrected direction
so the character moves at the same speed wether it's sliding or not
