Hello I'm a new game dev trying to make a platformer with the typical dash mechanic my code has no errors but when playing, the dash just entirely does not work.
my code is below I'm sorry if I'm just missing something simple.

extends KinematicBody2D

const UP = Vector2(0, -1)
const GRAVITY = 22
const MAXFALLSPEED = 350
const MAXSPEED = 150
const JUMPFORCE = 420
const ACCEL = 100

#dashing var
var dashDirection = Vector2.ZERO
var canDash = false
var dashing = false
var velocity = Vector2()
var screen_size

var motion = Vector2()
var facing_right = true
var start_position = Vector2.ZERO
var facing


func _ready():
	start_position = position
	screen_size = get_viewport_rect().size
	
	
func _process(_delta):
	if position.y > 250:
		position = start_position
	$fps.text = str(Engine.get_frames_per_second())

func _physics_process(delta):
	
	dash()
	
	
	motion.y += GRAVITY
	if motion.y > MAXFALLSPEED:
		motion.y = MAXFALLSPEED
	
	if facing_right == true:
		$Sprite.scale.x = 1
	else:
		$Sprite.scale.x = -1
	
	motion.x = clamp(motion.x, -MAXSPEED, MAXSPEED)
	
	
	if Input.is_action_pressed("right"):
		motion.x += ACCEL
		facing_right = true
		$AnimationPlayer.play("Running")
	elif Input.is_action_pressed("left"):
		motion.x -= ACCEL
		facing_right = false
		$AnimationPlayer.play("Running")
	else:
		motion.x = lerp(motion.x,0,0.2)
		$AnimationPlayer.play("Idle")
	
	if is_on_floor():
		if Input.is_action_just_pressed("jump"):
			motion.y = -JUMPFORCE
	
	if !is_on_floor():
		if motion.y < 0:
			$AnimationPlayer.play("Jump")
		elif motion.y > 0:
			$AnimationPlayer.play("fall")
		
	motion = move_and_slide(motion, UP)


func respawn():
	position = start_position
	
	
func dash():
	if is_on_floor():
		canDash = true
		
	if Input.is_action_pressed("right"):
		dashDirection = Vector2(1,0)
	if Input.is_action_pressed("left"):
		dashDirection = Vector2(-1,0)
	
	
	
	if Input.is_action_just_pressed("dash") and canDash:
		velocity = dashDirection.normalized() * 100000
		canDash = false
		dashing = true
		yield(get_tree().create_timer(1), "timeout")
		dashing = false
		canDash = true

    WerdnaDev I think what's happening is your dash if statements are conflicting with each other because they are executing at the same time due to you calling the dash function, debug using print (canDash) you also don't need to use yield in Godot, there are timer nodes that are much less finnicky to get working and they have built in signals for what you're trying to do.

        Lethn thank you I will be trying this when I get home and will give you an update 👍

          Lethn hey i used print to debug and its printing what im asking it too but my character is still not dashing

              Megalomaniak i rewrote the code a bit and got the dash to semi work now no matter the value my player dashes very slightly extends KinematicBody2D

                WerdnaDev Please post what you did so that if anyone comes across this in the search they know what's going on, big pet peeve of mine lol.
