How to make the script say if the player is on a team then do a function? [UNSOLVED]

You have two functions of the same name. Assuming that you're unsure which function to use, I'd opt for the first one for simplification reasons, but it really doesn't make that much of a difference.

What you should be focusing on is the PlayerAdded/CharacterAdded anonymous function.

local groupId = 0
local tool = game.ServerStorage -- Tool

function onPlayerSpawned(player)
    if player:IsInGroup(groupId) then 
        tool:Clone().Parent = player.Backpack
    end
end

game.Players.PlayerAdded:connect(function(player)
    onPlayerSpawned(player)
    player.CharacterAdded:connect(function(character)
        onPlayerSpawned(game.Players:GetPlayerFromCharacter(character))
    end)
end)

:GetPlayerFromCharacter() gets the player instance from the character object.

The script is pretty much saying for every player that joins the game, do this to the player.

For every character that joins the workspace, do this to the player.

You could also add it to the player's StarterGear if you don't want the script to take up activity (the activity it takes up is pretty much insignificant, but oh well).

local groupId = 0
local tool = game.ServerStorage -- Tool

function onPlayerSpawned(player)
    if player:IsInGroup(groupId) then 
        tool:Clone().Parent = player.StarterGear
    end
end

game.Players.PlayerAdded:connect(function(player)
    onPlayerSpawned(player)
end)

Make sure that

• the script

  • is a server-sided script

  • is located in the Workspace or ServerScriptService

• the tool

  • is defined
