How would i go about detecting a tool's owner?

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve? Keep it simple and clear!
   I’d like to simply detect the owner of a tool via script.

2. What is the issue? Include screenshots / videos if possible!
   I wanted to know if there was a simpler way to do it. For example:
   
   I have this script inside of a tool, and i wanted a way to detect the player that “owns” the item regardless of if it’s in the player’s backpack or in the player model.

3. What solutions have you tried so far? Did you look for solutions on the Developer Hub? (yes)
   The most reasonable way to go about doing it is by using

local Player

if Tool.Parent.Name == "Backpack" then
    Player = Tool.Parent.Parent
else
    Player = Players:GetPlayerFromCharacter(Tool.Parent)
end

However i was wondering if there was a simpler solution like Tool.Owner or something. If not i’ll just do the method shown above. Thanks!

Your method will work just fine.

Could do

Tool.Parent:IsA("Backpack")

if you are worried that someone named “Backpack” will join the game.

Having a player named “Backpack” break a bunch of games would be kinda funny tbh. While this wasn’t the original question, i will mention that there is already a player named “backpack”

But since they didn’t use an uppercase B at the start, now nobody else can take the name and this bug can never truly appear

As far as I know your method is fine. Script in tool, script is always with tool, script holds info on the tool owner, script finds tool owner once and never changes it.

If your game allows players to give tools to other players and you plan on running that owner check via a script in every tool, well I personally wouldn’t but I don’t know if it’s a bad idea or not.
The way I’d set it up is have scripts in every player that does owner checks (you could do it on the server too, but since your script is in the tool I assume doing the check on the client is fine) and the server stores info on who owns what, so that I can have a million tools and the ownership data is all in one place.

Maybe this?

local function GetToolOwner(tool)
if not tool:IsA("Tool") then return end
if tool.Parent:IsA("BackPack") then
     return tool.Parent.Parent
else
     return game.Players:WaitForChild(tool:FindFirstAncestorOfClass("Model").Name)
end

This will return a player instance that the tool is owned by. It may bug out if it is used on a tool that is not owned by any player.
