Does anyone have an idea why any creature spawned by this script shows up as "Friendly" on the unit list, even if it has been induced to attack a fort member?  I even manually set all of its enemy_status_cache values to -1, but it still insists on being Friendly.

[expwnent]

What unit flags does it have?

[Dirst]

What unit flags does it have?

Whatever the defaults are, since I don't know the flags at all.  I think I hear the sound of an impending facepalm on my part

marauder and active_invader are the most likely candidates if you want members of a siege. Wild animals should be hostile if you don't add them to your civ / group but there might be flags involved.

If you want a proper siege you'll have to do a custom lua script and do some stuff but I think that's only if you want them to be sort of "organized" and retreat under the right set of conditions.

I'm looking to spawn a wild animal.  The old spawn-unit scripts seemed to get that part right (if you ignore that it spawned lobotomized wild animals), but the way create-unit is working for me I get two zeros in the enemy_status_cache (which seem to represent the fort) and a Friendly designation that won't go away.  Spamming -1 onto every enemy_status_cache value for the new creature doesn't have an effect.

Enemy cache is not all powerful. It's a cache that is recalculated every so often. Check if the civ_id is -1 (if not set to -1).

The civ is already -1, which makes "Friendly" all the stranger.  I did wonder if "cache" meant that there is an "original" somewhere that could be manipulated directly.

Wasn't able to make wild animals via flags.  Even making them an invader or uninvited guest didn't seem to faze their friendly ways 

I hate to do it, but I'm going to have to roll back to using spawn-unit.

You may have already tried it, but have you made sure to set the training_level to 9 (WildUntamed)?

EDIT: Also, I think you need to give them a world_population_ref in unit.animal. I was able to turn tame pets into wild animals by setting

flags1.tame = false
training_level = 9
animal.population.region_x = 50
animal.population.region_y = 50

I just randomly chose the region numbers, just so it's something other than -1

[Dirst]

That's definitely worth trying.  I kept looking through HM-editor looking for differences between real wild animals and spawned ones, and all I could find was the animal population.  Didn't realize it was that easy to manipulate (had worries of a broken lookup pointer).

Thanks!

Yeah, I was fairly certain making something up for the population region would cause the game to freak out and do something weird, but it seemed to work fine, even on save/reload so I guess that the game really just looks to see if the animal belongs to a population outside of the fort.

[expwnent]

1. I think the above version didn't make it into r4. It's the most complete version I know of.

2. We will include it in the next version for sure.

3. I will also go back and tinker with it some more. It is probably still unstable.

[lethosor]

I added a nickname option to the one included in r4, by the way, so merging that would be good (since spawnunit depends on it).

Since I have very little experience with using DFHack for modding, I wanted to ask how to use this script so the unit is spawned by the use of an interaction and (if at all possible) be part of the group of whomever did the interaction (in case a sieger uses it).

Any answers would be deeply appreciated.

Bug in the latest lazynewb pack. You cannot delete trackstop conditions. Keeps prompting to delete the stop, but not the conditions in the stop. Seems to think it is one menu level higher.
