Temperature Traps; anyone made one?

[Sanaart]

So, hello! I've been thinking about this when playing in Tundra biomes where the cold could literally kill you, I wonder if anyone has actually made a successful heat or cold trap? I remember it being on the front page, but I've watched many a let's play and in my hundreds of hours of play time, I've never actually made one to help kill raiders. Since they always bash down doors, I didn't think it was doable. Can it be done?

The problem is getting an enclosed environment. I lined a stone hallway with wood walls and set incendiary IEDs. If even one tile is open to the outside, the room will never heat up. If I put a door (set to 'hold open') for them to enter through, they destroy it before it cud be closed on them. Getting a pawn to go around and build a wall in the opening can't work, because if there was a way around the hallway, the raiders wud use it. I admit to being fairly new to RimWorld and fairly dumb, but I just don't c a way to seal them in

I made an improvised temperature trap once when an infestation broke out in my freezer; I just turned the air coolers to max power.

lol u r too cool dude. get it? I did a similar thing where i had a pawn set the hive ablaze and close the door on the way out. This was in a bedroom near the center of a mountain stronghold, however. With vents. Turned out to b a bad decision for the colony as a whole. On the brightside, the bugs also died

I have theory crafted one, but I've never implemented it.

Recipe for baked Raider
Take a room, made of stone, not to large though.
Place stone doors front and rear.
Place something flammable, such as a bed inside the room (Originally the idea was to use a single tile crop field with an unroofed section which you close off as the raid starts. Maybe it can still be done, but I'd need to play about with the roofing mechanics. Its jsut Raiders seem to set crops on fire more consistently).
Place fuel sources inside the room.
Place low health item in the doorway that's set to "close", clothing is ideal.
Await raiders.

Raiders rush into the room, one will invariably set fire to the bed. This acts as your trigger. The fire would then spread to the item holding the door open. When this burns away the door should, theoretically close. Trapping the raiders inside with a huge fire.

As I said that's my Theory. No idea if it works. Never needed too try it out, as I just blow them up with HME.

We really need switches like in Gnomoria. If we had manual switches, pressure switches etc, then we could have raiders trap themselves.

I've only seen one working fire trap, and it was from a fairly old version, but I think the idea still works.  The key is finding a way to close the room. 

The one I saw had a small room full of wooden furniture to act as fuel attached to a long single tile tunnel, a stone door to stand in and throw molotovs, and a turn in the tunnel that allowed a colonist to stand inside the base diagonally connected to the tunnel. 

When raiders/animals came in, a colonist would walk up to the tunnel, build a wall diagonally, thus sealing the room.  Another colonist would toss a molotov onto the wooden fuel.  Then everything inside just died. 

Assuming diagonal building still works, this design should still work great. 

Theory crafting of other ways to seal the room is really what is needed to make temperature traps a reality. 

Diagonal building (safe)
Open Doors (hard to close, raiders destroy, not sure about animals)
Colonist builds and tries not to die (only works with really long rooms, multiple entrances and cover)
Overhead Mountain collapse via frag grenade destruction of supports (Fairly certain this can only seal the area containing the support, and probably crushes everything inside)

Any others I'm missing?

I saw that on YouTube recently, but can't find the video. The way he closed the tunnel was pretty ingenious.

I had a mountain fortress that had this long, tunnel-like back hallway (some raiders dug it out to enter my fortress from the rear). This back hallway led into a large chamber, so what I'd do is put wooden furniture in the large chamber, and as soon as the raiders entered this hallway I'd construct a wall segment behind them (I kept a storage zone of iron really close by the entry). Using another colonist, I'd light the wood furniture on fire wih a Molotov, then leave the room, lock the door and keep a repairer at it.

Most times I did this (I probably succeeded 3 or 4 times) I managed to incapacitate all raiders before the fire went out. One time, though, it actually burned hot enough to vaporize them.


Ps: this large chamber was initially constructed to burn up bugs, and did a great job of it. With bugs there's no furniture required, because you can light a hive and then the bugs will spread the fire around themselves.

so it's possible to use temp traps against raids effectively, but is it reasonable? It sounds too difficult to execute and too elaborate for anything but novelty use. But, I think impromptu heat trap is the safest way to deal with infestation. Like I said, a pawn set a hive on fire in his bedroom and the crickets cooked. I think the bed burned too, but we wouldn't even hav had to evacuate if i'd thot to block off the vents.
