Can scratch cloud variables save across computers? For example, if I save the cloud variable as 10, then log in from a different computer will that variable save from that other computer?
Answer:
Explanation:
Scratch cloud variables are a feature in Scratch, a visual programming language, that allows for saving and sharing data across different projects and even across different computers. Once a variable is saved as a cloud variable, it can be accessed from any other project that has been shared with the same Scratch account.
If you set the value of a cloud variable to 10 on one computer, and then log in to Scratch from a different computer using the same Scratch account, you will be able to access the variable and its value (10) from that other computer.
It is important to note that the cloud variable feature is only available for Scratch accounts with a login, if you don't have a Scratch account, you won't be able to use this feature.
It's also good to keep in mind that if you set a variable as a cloud variable in a project, it will be accessible to anyone who has access to that project. So make sure you understand the sharing settings and permissions before using cloud variables in a project that contains sensitive information.
