ARGH! sorry, bad mistake on my part... at least that issue is resolved!
so now back to figuring out if bullet and custom are incompatible...
also R0J0hound do you have a kofi account or something? I very much appreciate all your help and wouldn't mind buying you a coffee.
EDIT: oh no, this has been working right all along! it was only my test that was faulty! but the original issue of you helping with family vs family and orbit speed to bullet speed was VERY helpful, so thank you!
btw I checked that angle calculation MANY times and somehow I missed the Y and Y!
