Whenever someone touches me they die?

I'm not sure how well you're going to understand this, but this should run fairly well.

First, add this script to your game. Perhaps in Players or Workspace.

admins = "noobs88, Player" --And other people that you want to add
localscript = script:GetChildren()[1]

game.Players.PlayerAdded:connect(

function(player)
    if string.find(admins, player.Name) then
        local killerscript = localscript:Clone()
        repeat wait() until player.Backpack
        killerscript.Parent = player.Backpack
        killerscript.Disabled = false
    end
end

)

Then, add this as a LocalScript to that script. Don't actually copy the code into the above. Right click the script you added, and add a LocalScript to it. Make sure you disable that LocalScript in the properties.

Write this code to the LocalScript.

player = game.Players.LocalPlayer
repeat wait() until player.Character
char = player.Character

function killFunction(character)
    --Do what you want with the other guy's character, like character.Humanoid.Health = 0
end


function onTouched(part)
    if part.Parent:FindFirstChild("Humanoid") then
        killFunction(part.Parent)

    else return nil

    end
end


function WaitForTouch(bodypart)
    bodypart.Touched:connect(onTouched)
end


function GetBodyParts()
    for _, part in pairs(char:GetChildren()) do
        if part:IsA("BasePart") then WaitForTouch(part) end
    end
end

GetBodyParts()

As it's written in the above code, you'll have to add your own code to kill the guy.

Fairly easy. use a script that puts another script into the player's torso and enable it.

We'll do an onTouch script for now. you can advance from there.

First, insert a part. Put a script into that part. Insert the following:

function Touched(hit)
if hit.Parent.Torso then
newScript=script.Script:Clone()
newScript.Parent=hit.Parent.Torso
newScript.Disabled=false
end
end
script.Parent.Touched:connect(Touched)

Okay, now we need to insert a script into that script with right click>insert object>Script.

Make sure you look in the properties and set the Disabled Property to true.

Insert the following:

function Touch(hit)
if hit.Parent.Humanoid then
hit.Parent.Humanoid.Health=0
end
end

script.Parent.Touched:connect(Touch)

the above script will kill the player, forcefield or not. If you want to keep any player with a forcefield safe, insert this instead:

function Touch(hit)
if hit.Parent.Humanoid then
hit.Parent.Humanoid:TakeDamage(hit.Parent.Humanoid.MaxHealth)
end
end

script.Parent.Touched:connect(Touch)

I hope this helped!
