Here is a peculiar set of functions I created for making code that will almost never break in game. Basically it works by searching up the object you are looking for every time with a series of gates to make sure the code doesn't error and break. Here is how to use it:

1. Paste this set of code to the beginning of your script:

Code:

debugIndex = {}
function temp(type)
   local debug = Instance.new(type)
   debug.Parent = Workspace
   debug.Name = "debug " .. script.Name .. " " .. type
   debugIndex[#debugIndex + 1] = debug
   return debug
end
function find(path, type, start)
   if start == nil then start = game
   end
   local debug = temp(type)
   local Locate = start
   local a = 1
   for i = 1, #path do
      local temp = Locate:findFirstChild(path[i])
      if temp == nil then
         print("Failed to find " .. path[#path])
         return debug
      else
         Locate = temp
      end
      a = i
   end
   if a == #path then
      debug:Remove()
      return Locate
   else
      print("Failed to find " .. path[#path])
      return debug
   end
end
function cleardebug()
   for i = 1, #debugIndex do
      debugIndex[i]:Remove()
   end
end

2. Search for a value starting at game (as in game.Workspace) like this:

Code:

find({"Workspace","Brick"},"Part")

or starting at another part like this:

Code:

find({"Head","Face"},"Decal",Player)

3. Run this function every so often to get rid of the extra debugs

Code:

cleardebug()

Most average scripters won't need this, but for you few who have huge complex scripts, this could be really helpful in making your place impervious to breaking.
