I'd like to use Biome Tweaker to have faction NPC's eventually spawn in different biomes even though I'm not having any of the structures actually spawn in my world. The problem is that I can see you are using tags on the entity object.

For example, the entity class for several different Faction NPC's is:

"net.shadowmage.ancientwarfare.npc.entity.faction.NpcFactionMountedSoldier"

And normally that is what I'd put into the code to spawn them . . .

But I'm pretty sure that is going to give me an error because the summon command for registry ID "ancientwarfarenpc:faction.cavalry" failed to return any unit. Instead, it gave me the error "unable to summon object".

So I can be pretty sure that:

"NPC.addSpawn("net.shadowmage.ancientwarfare.npc.entity.faction.NpcFactionMountedSoldier, "CREATURE", 8, 4, 8)

is also going to be wrong.

My question is if there actually is a way to reference these both for the summon command and for Biome Tweaker's code. I'm thinking that it's:

"net.shadowmage.ancientwarfare.npc.entity.faction.NpcFactionMountedSoldier.withTag({npcSubtype: "", faction: "buffloka", npcType: "faction.cavalry"})"

but I'd rather ask than put that into my code and have it error out on me. I know just enough here to try something and have it be really stupid . . . so it's best to just ask the expert . . . which would be the mod developer. lol

It could be really cool if I'm able to use biome tweaker to get them to spawn naturally and then use mob stages to have them appear at the right time . . . each in the proper biome xoltec in the jungle, bufloka on the plains, impi on the savanna . . . I really hope this works. The themed units look super cool.

I actually achieved what you are trying to do in 1.7, using JAS (Just Another Spawner) mod - patrols and invasion forces of mixed type AW NPC's by biome type - so as you say - Norska in snowlands etc, Zimba in Savanna. The problems I hit with this was that because under JAS the AW NPC's were classed as "creatures" to be spawned in daylight, they took over the spawn cap and eventually nothing else could spawn. Without attaching despawn tags to them all the biomes just became crowded out with AW NPC's - but I couldnt attach despawn tags to them without adversely affecting the AW NPC's in structures, which also despawned. So whilst "succcessful" in one way, it wasnt successful enough to be a viable option.

I'm not familiar with how Biome Tweaker works, so cant offer advice on that. However, AW does plan to do what you are suggesting eventually, npc raiders, and full scall siege invasions. But it wont be "soon".

So in JAS - these are examples of its 1.7 entries for the AW NPC names:

    "AncientWarfareNpc.viking.soldier": {
      "Weight-PassivePackMax-ChunkPackMin-ChunkPackMax": "0-4-0-4"
    },
    "AncientWarfareNpc.viking.soldier.elite": {
      "Weight-PassivePackMax-ChunkPackMin-ChunkPackMax": "0-4-0-4"

You can see its using the name of the mob - not the base entity name that you are quoting above
So if Biome Tweaker works the same way as JAS used to - thats what you need

So the AW NPC names are here:

Obviously, you dont need all of that name string for each entity. You probably just need - entity.ancientwarfarenpc.brigand.cavalry - for example. Not sure if any of this helps you, but if it does, could you let me know? And whether or not you get around the despawn problem I encountered before?

And just a word of warning - in the next update a lot of new factions get added and a lot of the above naming gets changed - so a lot of the work you do now on that list will need to be redone after the update.
