I still don't know how to limit Hunders' effect to one per turn. I mean, Pahunder and Mahunder can swarm the field, on top of that Kagetogake effect is always activated.

i have a question: When i want to work with my own ai_tutorial.lua file and i want to work with a priority list then i have to make my own function PrioritySetup()?. When does the ai calls this function? Do i have to call this function at the start of the duel?

the "end" should be a "else".

if a then
  return b
else
  return c
end

if a then
  return b
end
return c

Mm!! If i remember correct on the past there is a program called Puzzle Editor by francot514 where you are able to make puzlzle duels but also this program have some tools about ai scripting and there is an option to allow you to change the ai name though i never test it and it seems at this moment this Puzzle Editor have not anymore any ai scripting tool!!:(

Added another chunk of information. Also, for anyone wanting to use the custom functions provided by the AI in their own AI: Instead of adding the required files one by one, you can just use this line:

require("ai.ai")

This links your AI file to the standard AI file, and in succession to all files the standard AI uses. Also, any function you don't add to your AI will be taken from the standard AI then. Don't feel like creating a new attack target logic? Just don't include an OnSelectBattleCommand function, it should use the one from the standard AI instead (there might be issues, because its partly handled in OnSelectCard, but I'm sure that can be sorted out).

Snarky, it seems like the require("ai.ai") doesn't handle the summoning of monsters from the Extra Deck.

So, let's say that I want to add some Xyz monsters like Shark Knight and Ragnazero. Obviously, the AI needs info like if I have a a SS monster, if it's in attack position, etc.

So, instead of adding all that info, what should I do?

OnSelectInit(...

  --handle all your own stuff

  local result = SummonExtraDeck(cards) -- function handling a lot of generic extra deck cards
  if result then 
    return result[1],result[2]
  end
  return COMMAND_TO_NEXT_PHASE,1
end

All extra deck summoning is handled in OnSelectInitCommand. So if you use a custom one here, you will override the default AI summoning logic for that.

You can try to call the generic extra deck summoning logic separately, within your own OnSelectInit function. Something like this:

OnSelectInit(...

  --handle all your own stuff

  local result = SummonExtraDeck(cards) -- function handling a lot of generic extra deck cards
  if result then 
    return result[1],result[2]
  end
  return COMMAND_TO_NEXT_PHASE,1
end

Unfortunately, the AI is not modular enough, that you can implement all the parts by themselves at will. Many extra deck monsters are spread throughout different files, lots of functions you might want to include instead of remaking are within the main functions you will automatically override, if you declare new ones. Honestly, I am not sure, how to handle this the best way.

Snarky, could you please tell me about this function? and if I understan correctly this language?

So, far I've managed to copy-paste the functions for Feral Imp and Shark Knight. But Shark K. randomly targets my monsters. I still need to figure out how it decides what monster will "absorb".

function SharkKnightTarget(cards,min)              -- pass the minTargets count as well, just to be on the safe side. 
  return BestTargets(cards,min,TARGET_OTHER)  --Remember, the detach part targets 2 cards
end

I have added my something like ai.decks.name in ai.lua.

    require("ai.decks.EmptyJar")

DECK_EMPTYJAR = NewDeck("Empty Jar",38699854,EmptyJarStartup)
