[Solved] Restrict survivor's ability to attack

[Goregonzola]

Hey-hey!

I'm looking for a bit of guidance about a perk-idea I have in mind. The main goal would be that my survivor could only be able to attack entities with the "hostile" tag.

The prohibition code will probably be one of these, but I'm not sure how the frame of the perk should look like:

Quote

inst.components.combat.canattack = false
inst.components.combat:SetTarget(nil)

Is this a simple local function I should create or something more complicated?

I can't really think of an example for this, as far as I know only non-playable creatures can sort targets.

Thanks in advance!

Cheers!

You should be able to do this via a stegraph, where you just cancel the attack if not target:HasTag("hostile")...

Or something like that. Sorry I can't help more, I'm at work lol.

I've tinkered it a bit, but I feel like I'm still very far from the solution. This is the best I came up with so far, but better programmers will just probably just whisper a "Huh, pathetic..." line in anime style:

Quote

local function moral(inst, data)
        if inst.prefab == "samjack" and data.target.components.combat then
            if (not data.target:HasTag("hostile")) then
                inst.components.combat.canattack = false
                inst.components.combat:SetTarget(nil)
            end
        end
    end

This doesn't do anything at the moment : (

Okay, I tried adapting some code from my own mod, you'll need to change hatkid to your character's prefab, and add some extra stuff yourself. It will also only work if you have movement prediction disabled on your client. I'll help you later with how to get it working with it, just figured you can test this from now.

Put this in your modmain

AddStategraphPostInit("wilson", function(sg)
    local _attack = sg.states["attack"]
    local _onenter = _attack.onenter
    _attack.onenter = function(inst,...)
        _onenter(inst,...)
        if inst.prefab == "hatkid" and inst.components.combat.target:HasTag("hostile") then
        -- code if hostile
        else
        --code if not hostile
        end
        return
        end
end)

do not do this

Okay, ignore my previous post, that doesn't work. I've got a a second one for you that doesn't require you to have special code in your characters prefab file, it just works with whatever if statement you want.

AddStategraphPostInit("wilson", function(sg)
	local _attack = sg.states["attack"] -- This specifies which state we're adding to
	local _onenter = _attack.onenter
	_attack.onenter = function(inst,...)
		_onenter(inst,...)
		if inst.prefab == "hatkid" and not inst.components.combat.target:HasTag("monster") then -- this runs if the thing your character is attacking doesn't have the tag "monster"
			inst:ClearBufferedAction() -- Cancel the attack before it hits.
			inst.sg:GoToState("idle", true) -- Go to idle state, technically redundant but it keeps things neat.
			inst.components.talker:Say(GetString(player, "ACTIONFAIL_GENERIC")) -- This will use the characters speech file for this line.
		end
		return
	end
end)

In this example, once you change the prefab name (I used Hat Kid to test it), the specified character will not be able to attack anything that doesn't have the monster tag.

@TheSkylarr It works like charm, many thanks <3

I had to replace this line

Quote

inst.components.talker:Say(GetString(player, "ACTIONFAIL_GENERIC"))

with

Quote

inst.components.talker:Say("I cannot do that.")

but otherwise it works as intended.

Understandable change there, glad I could help. Personally I like having all my speech lines in the speech files, but if works, it works. Good luck with your project.
