Goal Oriented Action Planning (or any ai system at all)

#1

Hello, I’m here to ask if anyone has made a GOAP open-source or has any material or “tutorial” to give me a reference on enemy systems. I want to improve on my AI in my boss fighting game and I dont want enemies to have a behavior that they dont move despite having a target, or that they spam moves while moving forward. I want smart enemies that calculate their target’s potential move combos and predict their moment (which is what I currently got in targets) and use states to tell the enemy what to do during this state. I just need reference material and I can go all by myself. Any help is appreciated

I found this article on Medium about “Goal-Oriented-Action-Planning”. It’s in C# but he explains it well.

Hope this helps!

Oh, it certainly gave me an idea in the midst of reading. though this is merely an idea, what are yer thoughts?

local c = {}
c.Check = function(victim, boss)
    local state = boss:GetState() -- ex: attacking
    local victState = victim:GetState() -- ex: regenerating
    local outsideVars = {
        Distance
        BossHealth
        PredictedCombo
        Invulnerable
    }
    if outsideVars.VictimInvulnerable and state == "Attacking" then
        boss:SetState(Magnitude >= boss.WalkSpeed*5 and "FindNewEnemy" or "RunAway")
    end

    if victState == "Regenerating" and not outsideVars.VictimInvulnerable and state ~= "Attacking" or outsideVars.Invulnerable then
        boss:SetState("Attacking")
    end
end)

Yeah, I would say that is a pretty good idea. Making “GOAP” is a pain to do but will be worth it in the end!

Happy Coding!
