I am making a metroidvania game and i want to limit how many times the player can jump before colliding. my code is bellow:

extends KinematicBody2D

const GRAVITY = 10 # in pixels
const JUMP = 250 # start speed px/s
const SPEED = 200 # px/s

var velocity = Vector2.ZERO # (0,0)

func _ready():

func _on_Timer_timeout():
    print(str($Timer.wait_time) + " second(s) finished")

func _physics_process(delta):

    # if no keyboard input for left/right then x speed is 0
    velocity.x = 0 
        velocity.x = SPEED
        velocity.x = -SPEED

    velocity.y += GRAVITY

    if (Input.is_action_just_pressed("jump")):
        velocity.y -= 250

    velocity = move_and_slide(velocity)

Well, you can have for example

var jumps_available := 2

at the top of your code, then simply

# _physics_process
if Input.is_action_just_pressed("jump") and jumps_available > 0:
    velocity.y -= 250
    jumps_available -= 1

along with some kind of reset condition, such as

# _physics_process
if is_on_floor():
    jumps_available = 2

and that should give a rudimentary kind of double-jump functionality.

will floor count as any surface?

I don't know, it depends on how you move your character and stuff. If you want to reset on more than just hitting the floor, you can add or change the conditions.

the code doesn't work when on a tilemap? how should i fix this?

I don't know, I don't know what your code looks like at the moment. If your tilemap has colliders, then chances are you aren't moving your character in a way that's compatible with is_on_floor.

do you want me to send my code?
