How do I get and/or use cloud variables? I heard of them on the scratch wiki when I searched how to make a multiplayer game but I don't know to get them or use them…

They're just like normal variables, except that everyone can give them information and access their information. So if when I'm using your project, I set the cloud variable to “10” or something, it'll become “10” for you too. This is why they are used for multiplayer, because they are the only way for a project to send information between Scratchers.

To get one, go to make a normal variable, but click the checkbox that says ‘cloud variable’.

Use them for high scores! Well at least, that's a popular use for them!
