Just click the green flag, and the test will start. To run another test, click the green flag again. Also works for New Scratchers.
This project detects whether or not your device is connected to the internet, no cloud variables used. Also works for New Scratchers. This project uses a new feature found only in Scratch 3.0: the Google Translate extension. The project would automatically generate a random string and send it to the translation server. If the translation gives an empty value, the player is offline. If the translation returns a non-empty value, the player is online. Use with credit. Idea and everything else made by me.
