Yeah, i have copy paste you’re classdef, and i forget to replace this classdef without any ship, by mine (that same but with the ship ^^).

EDIT:
Oh, and i see you don’t use eAmiral in you’re classdef ? (For ship like SAJUUK (in my case anubisflagship for example)).

#22

is eAmiral a stock class in HWRM? I’m not aware of that

#23

Used in HW Classic, for Sajuuk and other Amiral ship, but doesn’t use in HWRM, so IA can’t build Sajuuk and other amiral ship.

EDIT :
The new error (after made lot of print to find the issue of other) :

 parameter: attempt to index a nil value
stack traceback:
   1:  function `CpuBuildSS_ProcessEachBuildShip' at line 61 [string ""]

Seems to have link with my Battlecruiser units :

ai_data[GOA_HATAK]=
	{
		Type="Ship",
		Require={CAPSHIPPRODUCTION,BATTLECRUISERIONWEAPONS},
		Upgrades={},
		UpgradeDemand=1,
		BuildShipChannel=0,
		BuildSubsystemChannel=1,
		UpgradeSubsystem=
		{
			{Num=0},
		},
		BasicDemand=0,
		UnitCap="Battlecruiser",
	}
#24

between line 60 and 61 of cpubildsubsystem.lua add print("Build ship is - "..buildShip). This is the “numbered” value of the ship that isn’t in ai_data or for which UpgradeDemand doesn’t appear in it’s ai_data.

You could try switching line 61 and 62 around.

[Edit]
I’m unsure of any proper way of getting the name of the ship, but you could try adding a new function

function getBuilderIndexPos(nShip)
  local nget = getn(squadclass[eBuilder])
  if (nget == 0) then
    print("No builders"); return
  end
  local npos = 0
  for i = 1,nget do
    npos = npos + 1
    if (squadclass[eBuilder][i]~= nil and squadclass[eBuilder][i]== nShip) then
      print("Builder at position "..npos)
      return
    end
  end
  print("Builder not found")
end

Then replace the earlier print function with print("Builder at pos - "..getBuilderIndexPos(buildShip))
Then in classdef.lua, find squadclass[eBuilder] and the ship should be at the position the print statement said. If all works, that unit is either not in ai_data, or it doesn’t include UpgradeDemand.

#25

Delete the whole “UpgradeSubsystem” thing if you don’t want to use this function

#26

It’s the mothership … But can’t build by the AI because it’s one ship don’t have build option in build.lua ^^

So, need to add to database the mothership ?
By the way, even if we have this error, AI build units and attack.

It’s more on Basicdemand value i need clarification. Higher value = more demand for AI (like : You need to build this when you can) or lower value ? :stuck_out_tongue: [Because i see, when all is 0, AI build the same number of Ressource collector / rafinery / corvette / fighter ]

#27

must be in build.lua, otherwise it is nil.

higher BasicDemand, the AI is more likely to build/research

#28

So mothership can’t build subsystem and that’s all … because i can’t add this ship in the build.lua, it’s the base ship added at the beginning …

#29

why not? you can restrict it, right?

#30

A restriction on unitcap, yeah. And the only ship can build mothership is the mothership … but can’t build with unitcap … Yeah i see… x)

#31

After Test, all seems to work but … When you have 3 different races AI, the game crash.

#32

that’s wired, any error report in the log file?
Does every single race’ ai run properly?

#33

single yes.

No Error on log. Crash for … nothing xD But crash on loading when load AI.

#34

I’ve loaded 7 races and it’s fine.
Files updated to 1.04, you may try again.
Please notice that the path for classdef.lua has changed.

#35

ok.

I will try that tomorrow :wink:

#36

I have update my file.

But, the AI don’t go harvest RU, only build and made “shopping” with a limited Credit Card :smile: It’s the first problem here … But i can launch more than 3 AI with 3 different race.

path for classdef.lua has changed, make sure you’ve load it correctly.

#38

Yeah i have already apply this change. Don’t worry about that ^^

Problem Solved … just edited the wrong file (file on my Dest’, and not the good file in ai xD )

:stuck_out_tongue_closed_eyes:

#39

Thanks a lot for this code, @HW_Lover! I’ve already implemented it in my mod for the next release (the source of the code will be listed in the mod description, of course).

@HW_Lover

There’s a bug reported by my players and that I reproduced: when the AI Script is turned on, trying to save the game lead to an immediate CTD (if I rename the ai folder as ai-old, it doesn’t crash) with the log saying:

parameter: invalid key for `next’
parameter: unable to recover; exiting

According to this (http://www.computercraft.info/forums2/index.php?/topic/11043-invalid-key-to-next/), it occurs when you add or remove a key from a table while iterating on it using next (e.g. in pairs()). Is there any way to fix this or is this an error from my implementation of the script?
