move_and_slide wall detection only works when pressing up against it

[Deltt]

I've switched to Jolt physics in my current project to test it out, and immediately noticed that is_on_wall_only() would not behave like it would in the default physics version. All Jolt 3D settings are left on default.

I'm using the method for wallsliding and walljumping in a 3D platformer, however it doesn't seem to trigger at all, unless my players velocity is constantly pushed toward the wall, and even then it seems to rapidly switch between returning true and false where as the in built physics would return true even while not giving any input/velocity other than downwards, given a perfectly vertical wall/surface.

I've been testing this using a copy of my current project with 0 changes made except switching to Jolt physics.

I'd be happy to share the project or give more information if that would be of any help.

Thank you for reporting this. I'm able to reproduce this discrepancy if I don't provide any velocity towards the wall, as you point out.

This looks to be a regression caused by #559, as reverting that change fixes this problem, but that of course reintroduces the issue that it was meant to fix, meaning ghost collisions.

I'll see what can be done to fix this while preserving that other fix.

If this helps in any way, fiddling around with the Resolver settings in the Jolt 3D settings and setting it to around 20% or lower will make it behave more consistently, but I assume it also should when left to the default value when it did in previous versions.

Sounds good. Thanks for investigating this issue :)

I am facing the exact same issue with CharacterBody3D nodes.
