The character refuses to jump; how do I solve the problem? Here the code:

extends CharacterBody2D

const SPEED = 300.0
var JUMP_VELOCITY = 350.0
var movedir = Vector2(0, 0)
var gravity = ProjectSettings.get_setting(“physics/2d/default_gravity”)

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

func movement(d):
movedir = Vector2.ZERO #pour ne pas que le personnage continue de bouger
if Input.is_action_pressed(“left”):
movedir.x = -1
if Input.is_action_pressed(“right”):
movedir.x = 1
if Input.is_action_pressed(“jump”) and is_on_floor():
velocity.y = JUMP_VELOCITY
if Input.is_action_pressed(“down”):
movedir.y = 1

if Input.is_action_pressed("left") and Input.is_action_pressed("right"):
	movedir.x = 0
	
if Input.is_action_pressed("up") and Input.is_action_pressed("down"):
	movedir.y = 0

move_and_collide(movedir.normalized() * SPEED * d)

Up is negative y direction.

Also, velocity will only have effect if you use move_and_slide()

3

so what can I do ?

It’s either:

var JUMP_VELOCITY = -350.0
---
velocity.y = JUMP_VELOCITY

or

var JUMP_VELOCITY = 350.0
---
velocity.y = -JUMP_VELOCITY

And call move_and_slide()

I tried but it dosn’t work

Can you show us your modified code? And please format it properly, there’s an explanation on how to do so here:

extends CharacterBody2D

const SPEED = 300.0
var JUMP_VELOCITY = -350.0
velocity.y = JUMP_VELOCITY

Here the code and how can I reduce this ?

var movedir = Vector2(0, 0)
var gravity = ProjectSettings.get_setting(“physics/2d/default_gravity”)

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

func move_and_slide
movedir = Vector2.ZERO #pour ne pas que le personnage continue de bouger
if Input.is_action_pressed(“left”):
velocity.x = -1
if Input.is_action_pressed(“right”):
velocity.x = 1
if Input.is_action_pressed(“jump”) and is_on_floor():
velocity.y = -JUMP_VELOCITY
if Input.is_action_pressed(“down”):
velocity.y = 1

if Input.is_action_pressed("left") and Input.is_action_pressed("right"):
	velocity.x = 0
	
if Input.is_action_pressed("jump") and Input.is_action_pressed("down"):
	velocity.y = 0

move_and_collide(movedir.normalized() * SPEED * d)

Please check the guide I gave you so you know how to format your code properly, you did not.

I’m new you know I tried it and it didn’t work so I went back.

10

Please click on the guide and expand the section called “Format your code” and follow it’s steps.

11

I don’t see the format your code in the godot doc

12

It’s not in the godot docs. I sent you a link in the above post called “Posting guidelines in help channel”, please click it to open it.

14

You still aren’t calling move_and_slide, you should replace your move_and_collide with it and remove the function arguments.

15

I change this now

'I tried but for no reason it doesn’t want to format the code
