Weapon trap "Needs item." [Fix found]
« on: February 23, 2015, 01:25:54 am »
I'm trying to make a trap corridor to quickly convert goblins into goblinite, but I keep getting hit with this frustrating message:


I've been getting this message every time I try to make a weapon trap (with two exceptions, as you can see) despite having plenty of both mechanisms and weapon components. Everything else in the "traps" category works properly, it's just the weapon traps that are causing me trouble.

Weapon traps are filled with weapons (up to 10 per trap, I believe), so you need to make weapons to be place into the traps. These can either be normal weapons (such as weapons captured from enemies), or dedicated trap component weapons (e.g. spiked balls and serrated discs).
Personally I use cage traps and menacing spike traps hooked up to a mine cart repeater.
Also, a single tile wide corridor makes it easier to kill the invaders off, since they are guaranteed to go from one trap to the next. The exception is the trade depot corridor, which is best made in a meandering fashion, since wagons can't cross traps.

Does your experience fit with this bug report?

If the reports are correct, this could make you entirely unable to build new weapon traps in this fort. Uploading your save and linking to it (after making sure it's not a hauling or burrows issue) could be helpful for Toady to track down and fix the issue.

do you have ranged weapons in the traps? it shouldn't be the problem, but t might be. Weapon traps with ranged weapons in them require ammo. It shouldn't give a needs item thing, but just check

That does seem pretty similar to what I'm having. When I get back home I'll upload the save and link it there. I've ruled out hauling and burrow issues. It sucks that I can't use weapon traps... Oh well. Spike traps it is.

Try removing bins from your weapons stockpile and trying again in a little bit.

I tried that and it worked. I've also made the changes to the hallway itself. I can't remember why I made it three tiles wide...

Reading his name would trigger it. Thinking of him would trigger it. No other circumstances would trigger it- it was strictly related to the concept of Bill Clinton entering the conscious mind.

True, but if you initially place a trade depot at the end of the corridor and then retrofit to have a separate trade depot entrance elsewhere, you end up with a 3 tile corridor that you typically trap. Happens to me in every fortress, since I start out building my trade depot in the courtyard the first year and then move it the second or third year to the end of a long serpentine tunnel with trap arrays.
