MultiPlay Authenticator #

Authenticator lets the server check the player’s credentials before letting them join in. Along with the purpose of uniquely identifying them.

About Encryption.. #

Currently, there’s no encryption yet. So sending raw passwords is HIGHLY not recommended. Instead, use a one-time temporary code to authenticate would be a better practice.

Writing the authenticator #

1. Write the Authenticator #

You can easily create it using the script template “Multiplay Authenticator”

Create a new Script with the Template “Multiplay Authenticator”

The script will be like in the following:

extends Node

@export var auth: MPAuth

func _ready():
	auth.authenticate_function = _auth_check

func _auth_check(plr_id: int, credentials_data: Dictionary, handshake_data: Dictionary):
	# Return authentication data, otherwise if failed, return false.
	return {}

You can write your own authentication logic in the _auth_check function. If authentication is a success, return with dictionary. Otherwise, return boolean false.

The user data you return can be accessed later using mpp.auth_data

2. Create MPAuth and assign it. #

Second, Create MPAuth node as a child of MultiPlayCore like the following:

MPAuth

Then, assign MPAuth to your script, as the following:

MPAuth

And you’re done! Go ahead and test it!
