Introduction

The Cloud Variable Extension helps you share data between different users in the same PictoBlox project. It lets you store values like scores, usernames, or game data in the cloud and update them in real time. When one user changes a value, everyone connected can see the update instantly.

You can easily connect your project to a server, create cloud variables, set or delete values, and check who is connected using simple blocks. Special event blocks let projects react when a user connects, disconnects, or receives new data.

This extension can be used for building multiplayer games, team projects, live quizzes, and collaborative experiments.

What is a Cloud Variable?

A cloud variable is a special kind of variable that stores information online in the PictoBlox “cloud”. These variables are updated on the server side in real time, with little to no delay in project events.
