godot 4.3

I was trying to make a momentum for a platformer but character will accel too fast and decel to fast Preformatted text

extends CharacterBody2D

@onready var animated_sprite_2d: AnimatedSprite2D = $AnimatedSprite2D

const MAX_SPEED = 200.0
const JUMP_VELOCITY = -230.0

#Jump counts
var jump_count = 0
var max_jumps = 2

var SPEED = 0.0
var acc = 2.5
var lastDirection: float
var Friction = 8
func get_input():
var direction = Input.get_axis(“Left”, “Right”)

calculate_speed(direction)
lastDirection = direction

if direction: 
	velocity.x = direction * SPEED
else:
	velocity.x = move_toward(velocity.x, 0, Friction * SPEED)

func _physics_process(delta: float) → void:
if not is_on_floor():
velocity += get_gravity() * delta

if Input.is_action_just_pressed("ui_accept") and jump_count < max_jumps:
	velocity.y = JUMP_VELOCITY
	jump_count += 1
	
	if is_on_floor():
		jump_count = 0
	
_set_animation()

move_and_slide()

get_input()

func _set_animation() → void:
if velocity.x < 0: animated_sprite_2d.flip_h = true
elif velocity.x > 0: animated_sprite_2d.flip_h = false

if velocity: animated_sprite_2d.play("move")

func calculate_speed(direction: float) → void:
if lastDirection == direction: SPEED += acc
else: SPEED = 0

if SPEED < 0:
	SPEED = 0
if SPEED > MAX_SPEED: SPEED = MAX_SPEED

Why don’t you just lower your acceleration and deceleration multipliers?
Sometimes you need to tweak the values until you find the correct ones.
You can use @export on variables to show them in the inspector and change them at runtime to find the correct numbers easier.

So just change the numbers on acceleration and friction?

You would probably have an easier time modifying velocity in a direction as you do without a direction. Both your acceleration and Friction variables are very low for the pixels per second units you should be using.

if direction:
	var target_speed: float = direction * MAX_SPEED
	velocity.x = move_toward(velocity.x, target_speed, accel * delta)
else:
	velocity.x = move_toward(velocity.x, 0, Friction * delta)
