[Bullet] move_and_slide_with_snap inconsistent is_on_floor

Godot version: 3.1 >

OS/device including version: Linux Manjaro

Issue description: I have a simple gridmap and kinematicbody, if my body stands exactly between 2 tiles with collision the is_on_floor() value jumps to True and False and makes the state inconsistent. If I'm on a tile (not near the edge) the is_on_floor() value is correct.

Steps to reproduce: Create gridmap with a simple cube (1x1x1) and collision. Create a map and set the kinematic body at (0, 0, 0).

Are you applying a downward force (like gravity) before calling is_on_floor?

[grevius5]

yes, I apply gravity to the velocity vector, but the problem was that I was using the FLOOR_VECTOR as (0, 1, 0) and the SNAP_VECTOR to (0, 1, 0), settings the snap vector y to negative value seems to work correctly. Now I have some problem with the wall collision if I have a velocity pointing a wall, move_and_slide_with_snap returns to me a velocity != 0 in the direction of the wall and not 0. An example velocity.x = -1 and I'm attached to a wall, move_and_slide return me -1 as x velocity and not 0

The snap thing sounds a bit like #34098?

Can be still reproduced in 3.2.4 beta 5, but occurs only when using Bullet Physics (default settings). Switching to Godot Physics 3D fixes the issue.

Is this still reproducible in 3.5 RC 1 or later? If so, could someone provide a minimal reproduction project to make this easier to test?
