My character walks down the slope slower than it should

Continuing the discussion from Character bouncing when moving down a slope:

Question

It walks up the slope at the intended speed of 250, but when it goes down it’s slower than that. Here’s the code:

extends CharacterBody2D


const SPEED = 250.0
# var speed_multiplier = 1.0
const JUMP_VELOCITY = 400.0
# var jump_velocity_multiplier = 1.0


func _physics_process(delta) -> void:
	
	# Gravity.
	if not is_on_floor():
		velocity += get_gravity() * delta
	
	# Walking.
	var walk_input = Input.get_axis("ui_left", "ui_right")
	if is_on_floor():
		velocity = velocity.move_toward(get_floor_normal().rotated(deg_to_rad(90)) * walk_input * SPEED, delta * 720)
	
	else:
		velocity.x = move_toward(velocity.x, walk_input * SPEED, delta * 360)
	
	# Jumping.
	if Input.is_action_pressed("ui_accept") and is_on_floor():
		velocity += (Vector2.UP + get_floor_normal()) / 2 * JUMP_VELOCITY
	
	move_and_slide()
	print(velocity.length())

Any ideas how to fix it? The floor is a Polygon2D if that matters. Thanks!

Don’t know if it has anything to do with your problem. But gravity only affects the .y part of velocity.
So velocity.y += get_gravity() * delta.

Do you have “Constant Speed” checked on your CharacterBody2D?

[pedka]

get_gravity() returns a vector

[pedka]

what do you mean by that? doesnt the last line of my script do that?

[gertkeno]

It’s a property of CharacterBody2D, by default it is off, when on the player will move up and down slopes at the same speed as flat ground.

Like @gertkeno said, there’s some settings you can play with that will alter this behavior under the Floor section. What you’re saying sounds like the opposite problem. You should go down faster on slopes, not slower if Constant Speed is checked. I recommend playing with the Max Angle and Snap Length values.

works like a charm, and i dont even need that whole get_floor_normal().rotated(deg_to_rad(90) transformation. it just works out of the box with velocity = Vector2.RIGHT * walk_input * SPEED
