[Help Wanted] Want to make it so butterflies don't run away from the player.

[Error_iD10t]

As the title says I've been trying to figure how this could be achievable--at least with the limited amount of knowledge I have with Lua since this is my first modding project. I've been mainly learning programming off of the simple crash courses and reading the game scripts themselves. I know in Wormwood's skill tree his Bee Kind skill does the exact thing that I'm looking for, however I don't see it anywhere when I look in the files so I'm kind of clueless. Would really appreciate the help!

[Baguettes]

Apparently Wormwood's checks will only see if his skill is activated and prevents butterflies from flying away from him, no tags involved.. This is stored inside a butterfly's brain file, so that's a bit beyond my knowledge.

I do not really see any possible solutions to this myself. Hopefully others can help, though.

AddGlobalClassPostConstruct("behaviours/runaway", "RunAway", function(self)
    local _shouldrunfn = self.shouldrunfn or function() return true end
    function self.shouldrunfn(hunter, inst)
        if inst.prefab == "butterfly" and hunter:HasTag("player") then
            return false
        else
            return _shouldrunfn(hunter, inst)
        end
    end
end)

AddBrainPostInit("butterflybrain", function(brain) --print(brain) if u need to debug
	local runaway
	for i,node in ipairs(brain.bt.root.children) do
		if node.name == "RunAway" then
			runaway = node
			break
		end
	end
	if not runaway then
		print("[butterflybrain] Couldn't find the 'RunAway' behaviour in this brain!")
		return
	else
		runaway.hunternotags = runaway.hunternotags or {}
		table.insert(runaway.hunternotags, "butterflywhisperer")
	end
end)

Anything with the "butterflywhisperer" tag will not have the butterfly run away

Both of these work really well! Thanks a bunch for the help I would've no idea what to do otherwise.
