What are the main triggers or stops for invasions?
« on: March 05, 2011, 04:33:12 pm »
I've been playing DF for quite a while, but for several games now I have been completely unable to lure invasions to my fortress.

What are the minimum pop/wealth levels at which goblin ambushes and invasions occur, and is there any information I can review that would indicate if they are too distant or extinct and will never come?

I like combat heavy games, but it's frustrating to play for 10+ hours only to slowly realize that you'll never be attacked, even though you've embarked in what appeared to be highly hostile areas. :P

Playing in .19 at the moment, so for all I know every goblin on the planet starved to death a century ago.

100 pop for all triggers. When embarking, hit tab until you see civilizations. Make sure it has goblins and that they are hostile.

I don't think that's right...

Sieges generally occur regarding wealth, and I think it's also related to an 80 population

Ambushes I'm not sure on, but I've had them with as low as 25 dwarves (Was churning out a fair bit of wealth)

Thieves/Snatchers happen once there's children or one lone item of decent value around. I get these with the initial 7

Big beasties won't come via the surface until you hit 80 population
They come by caverns anytime after they've been breached

I think what you mean is that the goblin civilization might very well be at Peace, but that doesn't mean they won't siege anyway. There's a red line that can appear next to a civilization that appears to mean that they really don't like you, in spite of any peace treaty.

I've got a theory that there are three triggers -- population, created wealth, and exported wealth -- and that you have to hit at least two of them for the sieges to start.

By the way, I design table top RPGs and other games. You can buy some.

From the "EVIL" entry in entity_default:

   [PROGRESS_TRIGGER_POPULATION:2]
   [PROGRESS_TRIGGER_PRODUCTION:2]
   [PROGRESS_TRIGGER_TRADE:2]
   [PROGRESS_TRIGGER_POP_SIEGE:3]
   [PROGRESS_TRIGGER_PROD_SIEGE:0]
   [PROGRESS_TRIGGER_TRADE_SIEGE:0]

The first 3 are ambush triggers; 20 pop, 10000 created wealth, 100 000 exported wealth.  The last 3 are siege triggers.  I believe the pop trigger is 80+, production and trade will not trigger sieges.  Changing any trigger to "1" should have them start ambushing or siegeing immediately.

Also, obviously, magma avalanches and tsunamis weren't exactly a contingency covered in the mission briefing.

I can assure you that Ardentdikes is not the first fortress to be flooded with magma. What's unusual is that we actually meant to flood it with magma.

That looks wrong... 10 000 created, and 100 000 exported? I somehow believe it should be the other way around, in which case they're the same requirements for getting a baron.

That can't be right. I get ambushes far earlier than barony.

Triggers are either/or. If you fulfill any one of them, a siege can happen. However, I think population is the bare minimum trigger.

I haven't been hit with sieges yet either, but I'm took special care to embark directly beside some gobbos this time around. I'm hoping this will help to bring additional trouble from them, and I also genned worlds until I got a "War" message with gobbos from the start instead of the dotted line for hostility. This is supposed to bring them on more quickly as well.
