What is the GetPlayerFromCharacter Function?

Can you guys tell me in a full explanation what this means? I looked on the Roblox Wiki and it still doesn't make sense to me. Thanks.

The GetPlayerFromCharacter function "returns the Player associated with the given character, or nil if the character is not controlled by a player"

If you have a player's character model (the physical model), you can find the corresponding Player instance for that character (the object in the Players service which has GUIs and the StarterGear and PlayerPack).

The essential is that it "undoes" player.Character, that is,

game.Players:GetPlayerFromCharacter( player.Character ) is player.

Because it returns nil (as opposed to erroring) you can also use this to determine if a given model is actually a ROBLOX player rather than something else in, for example, a Touched event:

view source
01-- Example touched event to give a player a weapon
02function onTouch(hit)
03    if hit.Parent then
04        local player = game.Players:GetPlayerFromCharacter(hit.Parent);
05        if player then
06            game.ReplicatedStorage.Weapon:Clone().Parent = player.PlayerPack;
07        end
08    end
09end
10somepart.Touched:connect(onTouch);

What do you mean by onTouch(hit)? What is the hit for? notes4u99 65 — 10y

That was just an example... For `Touched` event functions, the parameter is called `hit ` by most people. I'm not really sure why. It's the parameter referring to what object touched `somepart` in this case BlueTaslem 18071 — 10y

Thanks. I just got one more question. When you say "if hit.Parent then", what is the parent for? I know what it is but i'm just confused on how you used it. Sorry for asking so many questions. I'm a somewhat-new person to scripting and just started learning a couple days ago. notes4u99 65 — 10y

1) `Parent` is the container of an instance. So, for a brick, its parent will usually be the model that contains it. 2) `if (something) then` can be used to make sure `(something)` exists (if it's `nil`, the condition fails). 3) Putting these together, this makes sure that `hit.Parent` exists before continuing (`hit.Parent` can be `nil` from bullets that get deleted upon contact with something) BlueTaslem 18071 — 10y
