Im trying to create a tile in godot (2d) that changes the CharacterBody2D's up_direction in gd script. the idea is to move the player towards either up/down/left/right using changed gravity once they touch the specific tile. The code currently works for up/down direction, but not for left/right. When the CharacterBody touches a wall to the left or the right, is_on_floor() will always be false (should be true), why is this the case?
player.gd:

const SPEED = 150.0
const JUMP_VELOCITY = -300.0
# const FLOOR_MAX_ANGLE = PI - PI/4
var gravity_dir = Vector2.DOWN

# var velocity = Vector2.ZERO
