@Ruri As long as you’re making toy guns, that’s fine. I made this toy gun myself a while ago to play with my friends, and I even posted it on the forum.
@encephalon First, I studied different types of weapons, then I observed how various kinds of toy guns work. After looking around a bit and disassembling some toy guns, I created my own project from scratch.
Also, I don’t think anyone would block a project involving weapons if it’s for something like a video game concept design, as in this example.
