So I exported my game to
android and jump button dont work
left and right work but jump not
I used touchscreen button and in action I used KEY_SPACE
heres code for player
extends CharacterBody2D

const SPEED = 300.0
const JUMP_VELOCITY = -400.0

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("KEY_SPACE") 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
else:
	velocity.x = move_toward(velocity.x, 0, SPEED)

move_and_slide()

func _on_fallzone_body_entered(body):
pass # Replace with function body.

func _on_fallzone_body_shape_entered(body_rid, body, body_shape_index, local_shape_index):
get_tree().change_scene_to_file("res://scene.tscn")
