jump script not working

Question

Jump script is not working please help

script: extends KinematicBody2D

export var velocity = Vector2.ZERO
export var speed = Vector2(300.0,300.0)
export var gravity = 300.0
var Accel = 10
const UP = Vector2(0, -100)
const JUMP = -10

func _process(delta: float) -> void:

if Input.is_action_pressed("ui_right"):
    velocity.x += gravity * delta
    velocity.x = max(velocity.x , speed.x)
if Input.is_action_just_released("ui_right"):
    velocity.x = 0
if Input.is_action_pressed("ui_left"):
    velocity.x -= gravity * delta
if Input.is_action_just_released("ui_left"):
    velocity.x = 0

func physicsprocess(delta: float) -> void:
velocity.y = gravity
if Input.isactionjustpressed("uiup"):
velocity.y = -25

    velocity = move_and_slide(velocity,UP)

Comments

You should use func _input

Answer 1

An easy way to do jumping is to add "jump" to the input map then right this code:

func getdirection() -> Vector2:
-1.0 if Input.isactionjustpressed("jump") and isonfloor() else 1.0)
