Move_and_slide() trying to get it to work in godot 4

[grand vale]

Maybe try doing knockback = get_real_velocity() at the end instead.

Just looking at the docs, I believe that should give you the right velocity you want. The velocity is more like the requested velocity, though it says it's modified by move_and_slide so I have no idea how this is actually supposed to be used. The documentation for this is pretty shoddy.

It just says the velocity is modified, but doesn't say in what way. get_real_velocity hints that the velocity property isn't what you think it should be.
