The sorian PA AI thread

For PlanetHighestEnemyArmyThreat is it possible this could blind the AI to certain threats? For example, the highest enemy threat is a player with an all land army, and the second highest threat has an all air army, would that mean the AI would see the skies as being safe using the following test?

Code:

{
                  "test_type":"PlanetHighestEnemyArmyThreatRatio",
                  "string0":"Air",
                  "string1":"AntiAir",
                  "compare0":">",
                  "value0":0.9
               }

Or is it using the highest enemy threat value for the string being checked against?

Running a local server the SIM speed suddenly tanked, then after a short while it fixed itself. Happened around the time one AI fired the unit cannon. Also, this error appeared in the log just after the SIM speed returned to normal.

[23:02:22.047] ERROR Attempted to create a search space with a ground last voxel not owned by this nav world!

What's the format of a SpawnablePlanetCount test? My assumption is:

Code:

               {
                  "test_type":"SpawnablePlanetCount",
                  "compare0":"",
                  "value0":
               },

Also, is PlanetWithoutPresence a planet without the AI, or a planet without anyone?

At which stage is this an active base:

1. Orbital fabber arrives and queues a teleporter build
2. Teleporter construction begins
3. Teleporter completed
4. Units arrive through teleporter
5. Fabber arrives through teleporter
6. Fabber queues a build
7. Fabber starts build
8. Fabber completes build

I'm guessing somewhere from 1-3 as the AI seems to create bases for any and all build locations.

DistFromNearestEnemyThreat doesn't count the Commander. Does this mean it's not a part of any threat calculations? It would certainly explain a lot of the AI bomber behaviour around bases.

For planets where it knows where the enemy base ahead of time it should set this value at the start of the game.

I don't think SpawnablePlanetCount works, Sorian. I've setup an AI with only one thing it can build

Code:

{
   "build_list":[
      {
         "name":"Basic Air Factory",
         "to_build":"BasicAirFactory",
         "instance_count":-1,
         "priority":376,
         "builders":[
            "Commander"
         ],
         "build_conditions":[
            [             
               {
                  "test_type":"UnitCountOnPlanet",
                  "unit_type_string0":"Factory & Air",
                  "compare0":"<",
                  "value0":1
               },
               {
                  "test_type":"SpawnablePlanetCount",
                  "compare0":"<",
                  "value0":2
               },
               {
                  "test_type":"CanFindPlaceToBuild",
                  "string0":"BasicAirFactory"
               }
            ]
         ],
         "placement_rules":{
            "buffer":3
         }
      }
   ]
}

Without SpawnablePlanetCount it works fine, but with the check the AI does nothing. Change the check to >= 0 and it works again. Tested on Styx.

If an AI is set to idle does that mean it's not counted as a threat?

Positive. Take out the SpawnablePlanetCount block, or set it to >= 0 (but < 2 or = 1 don't) and it works fine. I was using it to test DistFromNearestEnemyThreat earlier by having the commander build an air factory which spams Fireflies, then having the commander build different structures depending on the DistFromNearestEnemyThreat value.

Oh sure, but I needed an idea as to what 300 units of distance actually equates to in-game. I might do something similar in the future to try and figure out how many points of threat different units represent.

D'oh! Thanks, Sorian. Sorry to waste your time on that one

The AI prioritises resources over the Commander with its SXX, even when there's no anti-orbital threat.

Are ships included in the AntiSurface threat count?
