Is there a way to not necessarily lock the mouse in the middle of the screen, but rather make sure that it stays within a small box in the middle and when it hits the edge will just go on the other side? And of course it only can do this while a boolean is said to be true. I checked old forums and I couldn’t find anything on it, also there are no libraries i could find either.

I cant lock it in the middle because I wouldn’t be able to calculate mouse movement… or would I? please help.

Use the Robot class. You should be able to find some relevant code in the old forum.

Or JOGL classes. Depends what renderer you’re using. Just found this searching on JOGL - [http://twicetwo.com/blog/processing/2016/03/01/processing-locking-the-mouse.html](http://twicetwo.com/blog/processing/2016/03/01/processing-locking-the-mouse.html)
