This is a guide on how to hide sprites. Hidden sprites are sprites that aren't on the sprite screen, but they are fully functionable. This can be good for sprites that you don't want people to see. The first step is to make the background black. (This is optional, but it helps.) It also helps if all the other sprites hidden. Then open up the paint editor. After that, a dot appears on the stage. (You may need to move the paint editor before you can see it.) Right click it, and click duplicate. Put it anywhere you want to. Select cancel on the Paint Editor. Double click it to access its script bar. Congratulations! You have made a hidden sprite!
