Hello !
I wanted to add a air dash for my platform game but i'm struggling to add it.
I watch a lot of tutorial but i still can't understand why it is not working.

extends CharacterBody2D

#Movement
var speed = 200
var jump_speed = -400
var gravity = 1000
var friction = 0.5
var acceleration = 0.5

#Dash
var dash_force = 400
var can_dash = false
var dash = Input.is_action_just_pressed("dash")

func _physics_process(delta):
	#check if is on floor
	if !is_on_floor():
		friction = 0.1
		acceleration = 0.25
		can_dash = true
	else :
		can_dash = false
		friction = 0.5
		acceleration = 0.5
	
	#Movement
	velocity.y += gravity * delta
	var dir = Input.get_axis("move_left", "move_right")
	if dir != 0:
		velocity.x = lerp(velocity.x, dir * speed, acceleration)
	else:
		velocity.x = lerp(velocity.x, 0.0, friction)
	
	#Dash
	if dash and can_dash == true:
		velocity.x += dash_force
	
	move_and_slide()
	
	#Jump
	if Input.is_action_just_pressed("jump") and is_on_floor():
		velocity.y = jump_speed

Can you help me please ?

  • Screatch dat.
    I realized, you trigger dash but you never watch for if Input.is_action_just_pressed("dash")

    do something like this

    #Dash
var dash_force = 400
var can_dash = false
#var dash = Input.is_action_just_pressed("dash") < --- remove this
    	#Dash
	#if dash and can_dash == true: <-- remove this line
        if Input.is_action_just_pressed("dash") and can_dash == true
		velocity.x += dash_force

    how does it not work? what does it do when you dash? demo video?

      You can see in this video that it's not working, i'm pressing my dash button (shift) everytime i'm in the air.
      The windows size is 640x360 if it can help.

        TheMikega #Dash
        if dash and can_dash == true:
        velocity.x += dash_force

        put a print statement after this to see if when you press button this part of the code gets execute

        velocity.x += dash_force
print("Dashing: %s " % velocity.x)

        Then maybe make dash_force bigger number? like 4000

          Screatch dat.

            Thank you !
            It's working, I watched tutorial that used godot 3 and thought it will not change much between 2 different version.
            Guess I was wrong hehe.
