To use, u need to replace the usernames in the project. In beta right now. Basically, if you see an unedited copy of your game (something really annoying), just play the copy of the game on your spare. It will refuse to work. Note: uses cloud vars. I didn’t make this to protect my work, but did it so I could make anti-piracy screens, just for fun.
To make the protection worthwhile (stricter protection [doing so may contradict community guidelines. Do at your risk]), add a bunch of random stuff in the “corrupt” sprite to make it take forever to load and to make it hard to find the copy protection code. Also, make the sprite handle something like jumping or how chests open or something so they can’t just delete the sprite.
