i did the nifskope changes gribb suggested and nothing happened. and then i noticed there's sections for mass and inertia, so i copied those over from a bottle -- the first clutter i found -- and now it works, although it pretends it's a bottle when sitting on the ground. but that's good enough to test and i can alter it later for better physics by copying something more like a giant metal box.
i'm currently trying to get my trap linkage script to properly notice traps, if i can't get my next idea to work, i'll post the esp and ask for some help there.
edit: yup, didn't work. forgot to put a readme in it, so here's the basics:
the game gives you a hidden perk that adds an activate choice to pressure plates, which adds a misc item pressure plate to your inventory and deletes the one you activated. the misc press plate has an activate script - which can be done after dropping - that either adds one to your inventory and deletes it or replaces it with APPressPlate activator. the AP plate has an activate script that is supposed to allow you to link it to a trap item, the only trap item i have is the rigged shotgun atm. the rigged shotguns can be made at a workbench with a scrap metal. when they're on the ground, you can activate them to pick them up, swap in the AP version of the activator, or leave it alone. the shotgun activator currently runs the normal script on activate to fire itself, or if you're the player activating it, brings up a msg menu asking you if you want to set it to link, pick it up, or leave it. setting it to link simply runs a line that adds itself to the formlist trapsobjectlist. so the order of operations is drop a plate, swap it for activator, drop a shotgun rig, swap it for activator, activate shotgun, activate plate and then the shotgun again. in theory this should work just fine. in practice, the plate's script isn't recognizing the shotgun rig as being in the list trapsobjectlist.
also, i added a workbench to the cell TestTraps, since that's where i'm doing all my testing.
edit: added current build to OP
re-edit: didn't scroll up far enough and thought this was the OP
perms: either a full fireworks display spelling out "Puppettron Made This" anytime a user accesses my content in-game, or just give me credit somewhere.
