Help with editing fossil_mound.lua

[nextwebber1]

This isn't really a question about modding... But I didn't know where to put it. Sorry. So, me and my friends have always wanted to fight the Ancient Fuelweaver on the surface. But we've just never been able to find a way to do that. But recently, I finally ran into a post talking about how to edit fossil_mound.lua to make it possible to fight the Ancient Fuelweaver on the surface. But the thing is, I have a few questions. 1: If I edit the .lua file, will my game become unplayable and/or will crash everytime? (Really don't know about that, sorry i'm new here ;-;) 2: How do I edit my fossil_mound.lua file to add this in it? 

local G = GLOBAL
if G.TheNet:GetIsServer() then
    local ATRIUM_RANGE = 8.5
    
    local function ActiveStargate(gate)
        return gate:IsWaitingForStalker()
    end
    
    local function IsNearAtrium(inst, other)
        local stargate = inst.components.entitytracker:GetEntity("stargate")
        return stargate ~= nil and stargate:HasTag("intense")
    end
    
    AddPrefabPostInit("fossil_stalker", function(inst)
        local function ItemTradeTest(inst, item, giver)
            if item == nil or item.prefab ~= "shadowheart" or giver == nil or giver.components.areaaware == nil then
                return false
            elseif inst.form ~= 1 then
                return false, "WRONGSHADOWFORM"
            elseif giver.components.areaaware:CurrentlyInTag("Atrium") and (G.FindEntity(inst, ATRIUM_RANGE, ActiveStargate, {"stargate"}) == nil or G.GetClosestInstWithTag("stalker", inst, 40) ~= nil) then
                return false, "CANTSHADOWREVIVE"
            end
            return true
        end
        
        local function OnAccept(inst, giver, item)
            if item.prefab == "shadowheart" then
                local stalker
                local stargate = G.FindEntity(inst, ATRIUM_RANGE, ActiveStargate, {"stargate"})
                if stargate ~= nil then
                    stalker = G.SpawnPrefab("stalker_atrium")
                    stalker.components.entitytracker:TrackEntity("stargate", stargate)
                    stargate:TrackStalker(stalker)
                else
                    stalker = G.SpawnPrefab("stalker")
                end
                local x, y, z = inst.Transform:GetWorldPosition()
                local rot = inst.Transform:GetRotation()
                inst:Remove()
                
                stalker.Transform:SetPosition(x, y, z)
                stalker.Transform:SetRotation(rot)
                stalker.sg:GoToState("resurrect")
                
                giver.components.sanity:DoDelta(TUNING.REVIVE_SHADOW_SANITY_PENALTY)
            end
        end
        inst.components.trader.onaccept = OnAccept
        inst.components.trader:SetAbleToAcceptTest(ItemTradeTest)
    end)
end

I know how to find and open the fossil_mound.lua file, but I don't know what to do next. I've tried deleting some parts of the file and replace them with the above, only for my game to keep crashing once I open it, so I always restored the file to its original state. I do have Notepad++. Oh, and this is what the original fossil_mound.lua file looks like: 

local assets =
{
    Asset("ANIM", "anim/fossil_stalker.zip"),
}

    "fossil_piece",
    "collapse_small",
    "stalker",
    "stalker_forest",
    "stalker_atrium",
}

local NUM_FORMS = 3
local MAX_MOUND_SIZE = 8
local MOUND_WRONG_START_SIZE = 5
local ATRIUM_RANGE = 8.5

local function ActiveStargate(gate)
    return gate:IsWaitingForStalker()
end

local function ItemTradeTest(inst, item, giver)
    if item == nil or item.prefab ~= "shadowheart" or
        giver == nil or giver.components.areaaware == nil then
        return false
    elseif inst.form ~= 1 then
        return false, "WRONGSHADOWFORM"
    elseif not TheWorld.state.isnight then
        return false, "CANTSHADOWREVIVE"
    elseif giver.components.areaaware:CurrentlyInTag("Atrium")
        and (   FindEntity(inst, ATRIUM_RANGE, ActiveStargate, { "stargate" }) == nil or
                GetClosestInstWithTag("stalker", inst, 40) ~= nil   ) then
        return false, "CANTSHADOWREVIVE"
    end

    return true
end

local function OnAccept(inst, giver, item)
    if item.prefab == "shadowheart" then
        local stalker

            if stargate ~= nil then

                -- override the spawn point so stalker stays around the gate
                stalker.components.entitytracker:TrackEntity("stargate", stargate)
                stargate:TrackStalker(stalker)
            else
                --should not be possible
                stalker = SpawnPrefab("stalker")

Soooo what do I need to do to make this work? What part of the original fossil_mound.lua file do I need to replace with the edited stuff? I know, I might sound dumb for making this post and it's not even about modding, but I'm new here and I need some help. ;-;

Stop stop stop. You don't edit the game files. That WILL mess up your game.

The code you have there (in the first block) is code for a mod.You make a new mod, put that code in your modmain.lua file, and set up your modinfo.lua file, and your preview image, and upload the mod. Can't comment on the code, because I never tried anything like this.

Find one of your simplest mods in your "mods" folder in your game files. I can recommend to copy a mod like "Quick Pick", since its files are very simple. Make a copy of that folder. Give it a name saying in few words what the mod is.

- Edit the modinfo.lua and set: all_clients_require_mod = true
- Also change the name, description, author and version number (just put in "0.1" or something).
- Get the TexTool (version 1.4.1) from here.
- Make a new PNG image (logo) for your mod. Make the image 128x128 pixels.
- Open TexCreator.exe and create a tex file from your image file.
- Replace the "preview.tex" file with the one you just made.
- Open the modmain.lua and delete everything in it. Paste in the code you have in your first block.
- Test the mod locally, to make sure there are no bugs.
- Get the "Don't Starve Mod Tools" on Steam and run it. Remember to change the game to "Don't Starve Together".
- Select the folder with your mod in it, and click on the button to upload the mod.
- Then move the folder you made out of the "mods" folder, since you will be downloading the mod from the workshop next.

If all goes well, your mod should appear on the Workshop, so you and your friend can both subscribe to it.
