Sometimes, raiders dig at your walls. Sometimes, raiders attack your walls. They do this to avoid coming into your beautifully engineered, meticulously constructed killbox. How could they!
Well, the bad news is, you CAN’T stop them. The good news, however, is that you CAN prepare for them! In this episode of RimWorld Science we examine exactly how sappers decide where to invade your base. This starts with a little discussion of pathfinding. Pathfinding work by trying to find a ‘cheap’ path to where a pawn is going. Normal pawns give walls an infinite cost, so they never path through them. Sappers’ pathfinding gives walls a much smaller cost, so they WILL path through them. But they also give defenses a HIGHER cost, so sappers will aim to path AROUND your defenses, including your lovely killbox.
By figuring out just what sappers are trying to avoid, though, we can prepare ourselves for them. We ask: Will sappers path to avoid turrets, deadfall traps, and bombs (IEDs)? The answers, it turns out, are Yes, No, and No. So we can design a base defense that exploits this fact!

One thing I have noticed about sappers is their X-ray vision! If you have a mountain barrier shielding you they will often attack what seems to be a random part of it... and they 'uncover' a hidden area which means they are a LOT closer to your inner area than you had expected. Damn cheats! :)

That's a good point. The pathfinding algorithm just scores the path -- it doesn't bother to check whether the raider has any way to *know* about it. (The same way the raider *knows* to path around your turrets even if those turrets are hidden behind a wall.)

Just to follow up a year later, I only recently purchased the game. The sapper omniscience is still there and is a bit unfair. I had one break down an untouched compact steel deposit. It was a weak spot in my already weak defense line, but the sapper should not have had any way to know that I had mined it out from my side.

@alespetranek8487 5 жыл бұрын

I had recently a sapper raid. Half of my people were on a trip outside of the base. They started diging through a mountain where it was thinner. Folks in the base were kinda shit fighters, my best pawns were on the way home. So i started building granite walls, to buy time, while the raiders digged from the other side. Everytime they dug deeper, there was new wall waiting. Eventually they gave up, even before my fighters could get back home.

Initial thought... Do doors count as blocking the turret's value the same way that walls do? If yes, you should be able to bait them into a killzone with turrets behind a "wall" of doors. Then set the doors to hold open and have a pawn run through them. Also would depend on if the sappers recalculate their path after certain events.

@BjornStrongndarm 7 жыл бұрын

+Eric Larkin Ooh, I likes the cut of your jib, sir! I didn't think to test doors, but now I wish I had. As for pathing: They will wander and then repath after being hurt. But (a) the turrets can maybe take them down while wandering, and (b) if they're close enough to their destination it might not be worth it to them to path back outside of the turret. It might not work, but it's definitely worth checking out.

I used a strategy that I've actually never seen anyone use by exploiting artillery shell placement for chain bombing. Maybe you could look into the mechanics of it since I didnt fully test it out. I had a huge kill box at the front of my base (wait for it...) BUT I built a thin wall at the back of my base with a huge pathway for sappers that wanted to sneak in. Along that hallway I placed 1 artillery shell every here and there just so they would chain explode. You can place only 1 artillery per square by making it a deposit with highest priority and then forbidding that same square just so your colonist will place the next shell in another deposit instead of stacking 25. By the end of that pathway (closest to my base) I have an explosive trap that will trigger the chain explosions. By the time a raider steps on that one, all the others are already inside and along the pathway and 100% of them die EVERY time (given you have a long enough hallway). It requires a lot of micromanaging to build but once done you dont need to lift a finger to defeat the entire raid lol. Its too funny too watch them get obliterated by one wrong step xD

BUT: If someone of a faction has walked into a trap, the faction will try to avoid that place the next time they raid you. So after they have found a trap, it will be caclulated for the paths cost.

@BjornStrongndarm 7 жыл бұрын

Right, I had forgotten about that. A bit of googling tells me the following: (1) If some members of a raid survive a raid, any traps that raid triggered will be remembered. (2) The memory will last for 3600000 ticks, which is one in-game year. So the strategy I suggested can have problems. But I don't know they're going to be all that bad. First, notice that in the smallish raid I spawned, no more than half the traps were sprung. (And I used sandstone traps, which are low output -- if I had used something strong like steel, probably fewer would have sprung b/c people would have died faster.) So the same faction with a similar sized raid *and* spawning on the same side of the map can still path to the same trap area; they'll just hit different traps. Plus, the odds of getting two (or more) sappers, within a year from each other, all spawning on the same side of the base, are pretty low. You can also make the system safer by using more trapping/shooting spots -- maybe two a side instead of one, with some on either side of the killbox. It gets expensive, but I think that's just the game balance. As you get richer / more likely to get sapped, you have to spend more resources preparing for it.

Nice. I took this idea, and made a longer kill box right next to my standard one. The only difference is this one has no turrets, and is capped of on the outside end with walls. Then i placed some turrets around the base with exception of the line going down that hall and then and then right to my apartment building. So, normal raiders go into the normal killbox, and die. Sappers pop the wall 4 squares away, and go down the turretless kill hallway then leads to the houses but ultimately still ends in death. Because it is right next to the standard killbox, my guys can just change position in a few seconds. Hasn't had a problem yet.

@TheBooyaah 5 жыл бұрын

I’ve figured out some effective ways to counter sappers. One of the best strategies was using a base design where normal raids would enter through one of 3 sides (top / left / right), and a sapper raid would only come through the bottom (which was a small kill box). The reason behind why this works is because all my bedrooms are central, and for a sapper to cut through my walls - it’s considered too expensive due to my defences. So they come through the bottom. You can keep an auto door open on the bottom as well - and when a raid occurs, if it’s a normal raid you can shut the door, or if it’s a sapper raid you leave it and they come through bottom. The bottom kill box is still very effective, just not as lethal as the defence system defending the top / left / right

@FoldAPieceOfWater 7 жыл бұрын

I assume the avoidance of turrets is also a factor when they drop in from the sky, since it seems like they always find the most awkward spot to drop in with no turret coverage. I don't know how I feel about it, just like with turrets they can't see behind walls, yet still path around. The best solution would seem that a system would be implemented where survivors would tell their faction where the turrets (and maybe even dead fall traps) were last spotted, and future attacks of that faction would now avoid that spot. So basically, to defend effectively, you'd have to rearrange your defences multiple times, or make sure there aren't any survivors and perhaps a trade-off, for sending prisoners back to their faction in exchange for good will. As it is now, I kinda feel it's a bit bs, and also think they should try to avoid deadfall traps to the extend just mentioned. It would also be interesting to know if Infestations also avoid turrets when spawning.

Great videos. I'd love to see one on raid size/frequency/composition. I know wealth affects size but it would be nice to know how much building wealth affects this versus item wealth (if there is a difference). I'd also like to know if the composition of the raids is influenced by any factors. By composition, I mean what gear the raiders carry, mech versus pirate raids, etc. There may not be any factors that affect frequency other than the storyteller, but this would be nice to know. I also have a couple of questions regarding things you've already covered: How are infestation affected by roof types? If I remove a thin rock roof can they still spawn on that tile? Regarding cover, when standing behind a wall, what is the shooting angle reduced to?

@BjornStrongndarm 7 жыл бұрын

Hmm, good questions about raids -- probably they would require a code dive, though! I suspect there are too many variables to figure out by just running tests. (Still, doesn't mean I can't do some research.) Also, I think if you're *behind* a wall it doesn't affect your shooting angle at all -- it's when there's *another* wall that gets in the way that you have a problem. Like, when you have: XO X Where X = pawn and O = wall, there's no shooting penalty. But if you have X O X then sometimes you can't hit. (Although the details of this are fuzzy, and now that I'm typing this out, this seems not 100% right either. NEED MORE EXPERIMENTS!) On the infestations: They can't spawn at all unless they're under a thick roof (overhead mountain). If there were a way to remove thick roof you could stop infestations, but you can't, at least not without dev tools.

I’ve noticed a silly thing about sappers. When they try to blow up things, they don’t account for friendly fire. I had a little gap in defenses in my colony, and for some reason (I don’t remember) I’ve decided to build a snaky corridor with doors in random places. Sometimes, when sappers target this corridor, the sapper will walk inside to attack one of the doors, but since there are a lot of turns he has to stay close to that door and will literally blow himself up. I haven’t yet tried to abuse that fact, but there might be a good strategy.

I had a sapper event as my last raid on base builder; Phoebe Chillax, in alpha 17, shortly before I launched all 14 of my colonists. I just had the master/masters draft and run out towards where the sappers had started from and where they were going to. I let the grenader take out the wall, and then released my swarm of boars, muffalos, alpacas, pigs, cows, chickens, and even three elephants. The main, large swarm didn't even make it to the hole in the wall as some alpacas, boars, pigs, and my pregnant elephant sacrificed themselves soon enough, I captured three downed prisoners, and I think buried four corpses. A little while later, after I had launched, I accepted a refuge who turned out to be incapable of violence. The remnants of my previous swarm (and some infants) took out a larger raiding party than the one above, and only like one or two of the raiders were heading towards my killbox where the main group of animals were waiting for them. I'm new to Rimworld, but my opinion goes that animal handling makes for an underrated defensive strategy and can prove rather powerful (you don't have to hunt for fine meals afterwards, everyone can practice medicine, your colonists might not suffer any damage, and I would guess that more raiders just end up downed for more potential captures/conversions). Even more so with fast animal swarms like boars or powerful animals like cougars, bears, muffalos, elephants, rhinos, and I wouldn't even underrate alpacas. You might only need special zones during the raid for the animals, and perhaps you have the potential to defend all corners of the map without walls. Though, manhunter animal packs would make for my biggest worry, but a killbox can take care of that.

I found animal swarms extremely good at stopping manhunter packs to. Also boomrats can be good for triggering infestation honeypots; just keep an animal area in reserve and use it to direct a few rats into the honeypot, insects down/kill the rats and the fires incinerate the bugs.

How does doors effect the walls. Do they alter the cost for stalkers? would 20 doors be as good as 20 thick walls?

@davidbass6780 4 жыл бұрын

So you could effectively trick the AI into going for the stronger defended areas by using wooden walls and having your colonists blow them up as soon as the enemies are close enough for you to feel like it'd be most effective? Using IEDs for example to get the turrets line of sight and to blow up any that try to retreat once walls destroyed?

Big groups of sappers will struggle big time vs spaced wall lines, they tend to take cover once they break walls and hey end up hitting each other with the grenades, sometimes to the point they run back home on without you intervining. Once they break through couple of wall lines outside there would be 1-2 rangers and 2-3 mlee guys easy to be killed by your group.

i was messing around and i hit on an idea: sappers do not avoid turrets blocked by walls, but do sappers avoid turrets blacked by doors? i'm trying out a new kill box built around the idea that you build a wall of doors with turrets spaced out every other spot behind them. when the raiders get into range i step some of my colonists into the doorways directly in front of the turrets, the rest of my colonists use the unopened doors as cover and shoot through opened ones.

Interesting, i hear about killboxes but with my base i build a perimiter wall with embrasures, bags, put turrets on all corners to give me some coverage and then i mass turrets around the entire base at chokepoints between buildings, to cover certain areas etc, and as a result i never get sappers yet instead i get very large raids that swarm my turrets and simply overpower them, and its at that point that i have to rely on mortars to damage enough raiders so they will flee as my 25 colonists in pa cant take out 500 raiders.

@cthulhu6095 7 жыл бұрын

A strategy I use is unclaim home areas from my outside walls and it appears they avoid anything not claimed by me, so long as they have a way to get into my base through tunnels and such. Maybe look into that?

Hmm, interesting thought. But they will dig through unclaimed walls that are in their way -- I've seen them dig through an Ancient Danger, which is unclaimed...

one thing about the traps/bombs is the AI cant see them unless their faction has previously triggered that trap/bomb so eventually the traps/bombs might become effective as deterrents

Yeah, people have pointed that out before. May need to rethink. (If you put the traps in a checkerboard pattern, it helps -- they CAN avoid the traps, they just won't unless they remember they're there.

@doctito2623 3 жыл бұрын

the question is what happens if the turrets are behind doors, better said behind open doors istead of walls. does it count as a wall and so the turret doesnt count against cost of traspassing. that would be nice for the killbox with turrets.

@BjornStrongndarm 6 жыл бұрын

They might path to it. If it's the only owned bed, they will. But I think they choose their pathing object as soon as they spawn in, so if you change bed ownership after they show up to get them to come to your killbox, it might not work.

I noticed something really odd in A15. Sappers didn't try to go through walls with different types of materials. So I had 1 layer of wood surrounding my base immediately followed by 1 layer of Granite. Sometimes they would throw at the granite, but after the granite blew up, they would give up on the wall. They wouldn't go through the wood. I haven't tried this on A16.

@BjornStrongndarm 7 жыл бұрын

Hmm, I didn't try layering. That might do interesting things with their algorithms. I did try just making a big wall out of different kinds of materials all around, and they didn't seem to show a preference for which kind of wall they wanted to come to.

Its easy to make it so they cant avoid traps such as mines you just build a straight line of mines around your base and watch them eat dirt as they splode from walking in to them.
