is_on_floor confused with walls?

:bust_in_silhouette: Asked By Y_VRN

I’m just a new Godot user (been a few months but probably totaled about a few weeks) and I had a 3D character. It works fine (jumping had problems but not my first priority for now,) until I jump while touching walls. As I do so I would instead fly up real quick instead of jump.

With a bit of diagnosing I saw that is-on-floor would register walls as floors(?), thus returning true apparently. This already bugs me and I don’t know how to fix this. Please help me. Thanks in advance!

Is what you’re using as floor the same as the wall?

I had this same issue, my mistake was that I was passing a higher value to floor_max_angle in move_and_slide. That was the reason that walls were treated as floor.
Passing a lower value fixed it
