Mod request: Tallbird friendly vs grass geckos.

[NamelessName]

Tallbirds are exterminating like 40% of grass geckos sometimes. How to make them friendly vs them? Someone who wants to make such a mod?

I took a look at it's prefab file and probably the only thing of interest it that is has a combat component. I'm pretty sure that tallbirds attack anything that gets close to their nests. The first thing I would think to do is to find some way of modifying some function in the combat component, probably a targeting system, to check if the one attacking is a tallbird and if the target is a grass gecko and then cancel the rest of the actions.

I think a good place to look for examples would be the eyeplant and wormwood. Eyeplants attack everyone except wormwood, so maybe there's a system of tags or a series of checks in one of the two files or component. Just whatever enemy/mob you can think of that has an exception (like webber and spiders)

Finally some help in this forum. Ok thanks man, I will take a look at the eyeplant and wormwood, thats a start.

I couldnt find where to edit the "tag" component...

[krylincy]

in the tallbird lua there is the function where it is decided to target or not 

local function IsValidTarget(guy)
        return not guy.components.health:IsDead()
            and inst.components.combat:CanTarget(guy)
            --smallbirds that aren't companions are parented
            --to other tallbirds, so don't target them!
            and (not inst:HasTag("smallbird") or inst:HasTag("companion"))
    end

So the quick and dirty fix for you could be to just add the smallbird tag to the grasgeckos

AddPrefabPostInit("grassgekko", function(inst) 
	inst:AddTag("smallbird")
end)

The correct way would be to rewrite this "IsValidTarget" function in the tallbird lua.

 

Not sure if removing the combat component may help but you can try it this way:

AddPrefabPostInit("grassgekko", function(inst)
	if inst.components ~= nil and inst.components.combat ~= nil then
		inst:RemoveComponent("combat") 
	end
end)

But I think this will also end up that nobody can kill them at all.

Thank you man for this very well written code. I added this into my mainmod.lua, however the first bit of code for smallbird, did not work at all (they still attack them). Its strange, I would have assumed it would work, so thats a shame.
The second code however did exactly what you said. So no one can attack them., but I dont want that (just tallbird). 

Is there any other piece of code you know would work? 

Either way, thanks so very much for your help. I learned a lot from just that small bit of code you gave me. This forum felt dead until you came around man.
