I'm very very new to this .lua stuff... Well, I have no idea how, but I squashed some of MDC's gunship turret .lua, Mehman's U-Boat .lua, and the Base.rte train .lua into one file.
Guess what I'm making?
No? - Understandable... An AC-130-like gunship.
My problem is that the turret is behind the dropship, any special line or something I need to add to make it appear in-front of the gunship?

change the type of particle it is

craft draw in front of actors which draw in front of particles

basically.

What I'd suggest, if you have the knowhow to do the lua-offsets, is to make the turret the sprite of the actual acraft, and then have the main body be an attachable that has its position constantly updated.

Thanks Grif, I'll give it a go.

EDIT: Way to difficult for me, is there anything at all that appears infront of a dropship?

In addition, on a different topic: Is it possible to pick an actor/weapon sprite depending on which scene it's playing on. Say I made desert, arctic, and generic camo for a gun, and I loaded Tundra 1, could I make it choose the arctic sprite? Or have three differently sprited actors, and have it choose one?

Just checking, are we sure that it's the class type and not the atomgroup depths at work?

Yes you could, but you'd have to drop the gun for it to change. Have each different camo as a frame of the gun's sprite, then write some fancy Lua to check the scene name and switch to the relevant frame.

atomgroup depth affects physics; draw order is hardcoded by class

at least, such is the extent of my knowledge, and I promise it is based on practical experience.
