Exercise 1 Bonus

Wait(Delay(1))
local AllPlayers = worldInfo:GetAllPlayersInRange(worldInfo,100000)
for i = 1, #AllPlayers, 1 do
  AllPlayers[i]:DropDead(0,0,0)
end

or

Wait(Delay(1))
local AllPlayers = worldInfo:GetAllPlayersInRange(worldInfo,100000)
for _,player in pairs(AllPlayers) do
  player:DropDead(0,0,0)
end

Note: the 'pairs' function is used to iterate over the key-value pairs of a table. Here '_' is used as a dummy variable for a key (number) which I don't need, and the value is put into 'player'.
