Trying to make my character jump

So basically I’m using a super cool tutorial to make my first game and they said to use the template godot gives for movement and its this:

extends CharacterBody2D

const SPEED = 300.0
const JUMP_VELOCITY = -400.0
@onready var sprite_2d = $Sprite2D

Get the gravity from the project settings to be synced with RigidBody nodes.

var gravity = ProjectSettings.get_setting(“physics/2d/default_gravity”)

func _physics_process(delta):
# Add the gravity.
if not is_on_floor():
velocity.y += gravity * delta

# Handle jump.
if Input.is_action_just_pressed("ui_accept") and is_on_floor():
	velocity.y = JUMP_VELOCITY

# Get the input direction and handle the movement/deceleration.
# As good practice, you should replace UI actions with custom gameplay actions.
var direction = Input.get_axis("ui_left", "ui_right")
if direction:
	velocity.x = direction * SPEED
	velocity.x = move_toward(velocity.x, 0, SPEED)


var isLeft = velocity.x < 0
sprite_2d.flip_h = isLeft

And the problem is that when I play my character It wont jump but it works for the guy in the vid and no one is complaining in the comments. This is a pretty recent video. My initial thought was that at the beginning I didn’t click mobile to make the project by accident but I didn’t think it would matter but I’m doubting myself so could anyone pls help :slight_smile:

why your jump velocity is -400? it must be positive.

and set velocity.y -= gravity * delta under if not is_on_floor():

Could you try printing something under the velocity.y = JUMP_VELOCITY line to see if that code executes or not when you try to jump?
