this is a small question, but i want to know how to override the original turtle.forward() with a turtle.forward that will act like this


turtle.forward(2)

will go forward 2

[AfterLifeLochie]

local turtleForward = turtle.forward

turtle.forward = function(times)
  for i=1, times do
   turtleForward()
  end
end

Easy. Use this:

oldFor = turtle.forward

turtle.forward = function(iSteps)
  local i = 0
  for i = 1, iSteps do
	oldFor()
  end
end




--Your code here


turtle.forward = oldFor

Should work. I think.


However, this only works on a per-program basis. If you want it to work on a computer, leave off the las line, and put it in startup.

Or the metatable way (cause they're awesome!)

turtle.forward = setmetatable({forward = turtle.forward}, {__call = function(self, n)
    for i = 1, n do
      self.forward()
    end
  end
})
