Thanks!
And I just meant that looking at the manual's scripting section, some posts here in the forum, and an external scripting tutorial (I think written by FredRichi, thanks!) helped me to figure out how it would probably work. The example I found only used four frames in the reload state, so I wasn't sure if that was a fixed number. But yeah it's not really spelled out in the manual.
Thanks for the help! I'm gonna try creating a weapon from scratch!
