How to make character scare beefalo?

[. . .]

When my character becomes insane i'd like for it to make beefalo and possibly other animals to get scared off like a koalafant but when you hit them they fight back (if they could). So, does anyone know what I should do because I have no idea how I would go about this ... I would really appreciate if somebody can bestow their superior coding knowledge on me  & thanks for reading !

Anything that controls the AI of an entity will be messing with the brain of the entity.

A brain uses behaviours for mapping out responses to criteria.

 

In your case you will want to use AddBrainPostInit to edit the brain of whatever you want to be scared, and put in a RunAway node with its hunterparams checking for your character's prefab and sanity levels.

 

It sounds simple, but messing with premade brains can get pretty hairy, especially if you don't make assumptions about the layout of the brain beforehand for maximum mod compatibility.

I did something like this (it probably doesn't make sense, right?)...

local AddBrainPostInit = function(inst)
inst:ListenForEvent("goinsane", function(inst, data)
local brain = require "brains/houndbrainInsane"
end

I tried putting it in and out of the local master_postinit = function(inst) in my character prefab but it just crashed the game .

Do you think you can tell me the correct way to put AddBrainPostInit because I think I put it a very wrong way but don't know how to properly do it ... I would appreciate if you could tell me  & thanks for reading !

GLOBAL.require("behaviours/runaway")

local function AddBeefaloFear(self)
	-- Beefalo entity, tag they run away from, distance they see spooker, distance to which they run away
	local fear = GLOBAL.RunAway(self.inst, "sparkspooker", 6, 12)
	fear.parent = self.bt.root
	-- Insert fear right after ChaseAndAttack
	table.insert(self.bt.root.children, 5, fear)
end

AddBrainPostInit("beefalobrain", AddBeefaloFear)


local function ApplyFearTag(inst)
	inst:AddTag("sparkspooker")
end

local function RemoveFearTag(inst)
	inst:RemoveTag("sparkspooker")
end

local function AddBeefaloFearOnInsanity(inst)
	if inst.components.sanity then
		inst:ListenForEvent("goinsane", ApplyFearTag)
		inst:ListenForEvent("gosane", RemoveFearTag)
	end
end

AddPrefabPostInit("wilson", AddBeefaloFearOnInsanity)

Put all of this in modmain. Edit "wilson" to your character prefab. This adds a new behaviour to beefalo brains.

[CarlZalph]

AddBrainPostInit("beefalobrain",
    function(self)
        if(self.bt and self.bt.root and self.bt.root.children)
        then
            for k, v in ipairs(self.bt.root.children)
            do
                if(v.name=="ChaseAndAttack")
                then
                    GLOBAL.table.insert(self.bt.root.children, k+1,
                        GLOBAL.RunAway(self.inst, "yourcustomtag", 6, 12)
                    )
                    break
                end
            end
        end
    end
)
AddPrefabPostInit("waxwell",
    function(inst)
        if(inst.components and inst.components.sanity)
        then
            inst:ListenForEvent("goinsane",
                function(inst)
                    inst:AddTag("yourcustomtag")
                end
            )
            inst:ListenForEvent("gosane",
                function(inst)
                    inst:RemoveTag("yourcustomtag")
                end
            )
        end
    end
)

DarkXero beat me to the punch, but sleep and such.

 

Though I like my method of injecting into the brain table better as it allows for higher mod compatibility, following the koalaphant's order of RunAway node logic.

 

Not sure why DarkXero's requiring the behaviour, though- the patch applies fine without it on my end.
