Closures · Function

checkcaller

Returns whether the current function was called by the executor.

function checkcaller(): booleanbooleantrue if the current caller is executor-owned, false otherwise.

Usage

Security guard

hookfunction(game.Workspace.FindFirstChild, newcclosure(function(self, name, recursive)
	if checkcaller() then
		print("Executor called FindFirstChild for:", name)
	end
	return hookfunction_original(self, name, recursive)
end))

Synopsis

Overview

Returns true when the current thread was spawned by the executor, false when it was spawned by a game script. Internally it reads the thread's identity level to make the distinction.

Typical pattern

The most common use is inside hooked functions. Let game-side calls pass through unmodified while applying custom logic only when the executor is the caller:

hookfunction(target, newcclosure(function(...)
  if not checkcaller() then
    return old(...) -- game called it, pass through
  end
  -- executor called it, do custom logic
end))
