Need HELP to make Blunderbuss deal specific dmg vs mob has tag "animal" [SOLVED]

[Psychomaniac]

Hi guys, thank for coming here!

Ok! The thing is: I used a mod that bring Blunderbuss to DST. i want to made it deal 1000 dmg to mob that has tag "animal" so i can one shot them (for Hunting role play :D, only a few mob has tag animal: koalefant, beefalo, volt goat...).

In Blunderbuss.lua file, there are lines:

Spoiler

local function OnAttack(inst, attacker, target)
    print("OnAttack")
    if inst:HasTag("blunderbuss") then
        inst.components.inventory:RemoveItemBySlot(1)
        OnLoseAmmo(inst, attacker)
    end
    --spear.components.weapon:OnAttack(attacker, target, true)
end

Which i think made Blunderbuss remove ammo when fired a shot.

I then tried add these line into Blunderbuss.lua file:

Spoiler

local function onattackanimal(inst, attacker, target)
    if target:HasTag("animal") then
        inst.components.weapon:SetDamage(1000)
    else
        inst.components.weapon:SetDamage(damage)
    end
end

and this line under local function fn() section of Blunderbuss.lua file:

Spoiler

    inst.components.weapon:SetOnAttack(onattackanimal)

Log-in to the game: 

First shot on a beeffalo deal base dmg, but not consume the ammo like it should, 2nd shot deal 1000 dmg still not consume ammo and so on...

after a couple more shots the game crash.

Then i deleted all the code that i added and tried to improvise something like this (add a part of the code into the original "OnAttack"):

Spoiler

local function OnAttack(inst, attacker, target)
    print("OnAttack")
    if inst:HasTag("blunderbuss") then
        inst.components.inventory:RemoveItemBySlot(1)
        OnLoseAmmo(inst, attacker)
    end
    --spear.components.weapon:OnAttack(attacker, target, true)

    if target:HasTag("animal") then
        inst.components.weapon:SetDamage(1000)
    else
        inst.components.weapon:SetDamage(damage)
    end
end

Log-in to the game: 

Blunderbuss now function like normal (deal base dmg, consume ammo, like those extra code i added was nothing).

Please help if you can!!!

Thank for reading.

Doing something like this for a certain weapon can be tricky since weapon component, unlike combat component, doesn't have bonusdamagefn. But you can approach this problem in a different way. If you know every entity with the animal tag you can manually create a table with their prefabs and add a function to kill it if the weapon is a blunderbuss:

local table = { -- The table with prefabs of animals
	"beefalo",
	"koalafant",
	...
}

for k,v (table) do -- Loop for all the prefabs in the table
	AddPrefabPostInit(v, function(inst) -- Add prefab, 'v' being prefabs from the table
		local function OnAttacked(inst, weapon) -- OnAttacked function
    		if inst.components.health and weapon.prefab == "blunderbuss" then -- Check for health component and what is the weapons prefab
				inst.components.health:Kill() -- Kill, if all conditions are met
			end
		end

		inst:ListenForEvent("attacked", OnAttacked) -- Listen for event 'attacked'
	end)
end

 

This method will allow you to basically have full control over what entity is one-shot kill from the blunderbuss. Other way you can do it is by checking every prefab in the game with a 'for' loop and checking if it has the "animal" tag, then adding the function above. Of course this method is a bit less tidy and controllable.

The only other option you have is probably overriding the weapon component, adding some sort of bonusdamagefn, similar to the combat component, but that's a lot of work and I think there are better options.

Pretty sure the blunderbuss uses a projectile, which has an OnHitFn you can use.

Hi guys (@IThatGuyI, @penguin0616) !, first i want to thank you for taking your time to help me with my stuff.

The reason why i didn't post anything until now is because of my coding skill level is like next to zero, for that i can't make the magic happen (even how detail @IThatGuyI explain the code :D), and i don't want to trouble you guy more.

After many tries and fail, i'm kinda give up, then i went on Steam's Workshop (like i always do) search for items, or char that have items that deal extra dmg to a specific type of mob. After many hours, i found a few mods that does.

Then after a few hours digging, i finally cooked up some lines:

if (target:HasTag("animal") or target:HasTag("pig")) then	-- you can add more mob tag into the "()"
		target.components.combat:GetAttacked(attacker, 1000, inst)	-- 1000+ bonus damage
	end

Then i saw @penguin0616 mentioned OnHitFn, i then search for OnHit in blunderbuss.lua file, and did find one.

One more try doesn't hurt, i then added the new code in:

local function OnHit(inst, attacker, target, weapon)
    local impactfx = SpawnPrefab("impact")
    if impactfx and attacker then
        local follower = impactfx.entity:AddFollower()
        follower:FollowSymbol(target.GUID, target.components.combat.hiteffectsymbol, 0, 0, 0)
        impactfx:FacePoint(attacker.Transform:GetWorldPosition())
    end

	-- Deal extra dmg vs mobs have tag mentioned, you can add more mob tag into the "()"
	if (target:HasTag("animal") or target:HasTag("pig")) then
		target.components.combat:GetAttacked(attacker, 1000, inst)	-- 1000+ bonus damage
	end

    inst:Remove()
end

and it's worked . OMG     !!!

Again, thank you for your help, much appreciated. GG.
