Okay first off thanks for looking at my post, okay I'm trying to avoid the "LONG" turtle commands for my programs so I decided to create functions insted, example:

function digforward()
turtle.dig
turtle.forward
turtle.digUp
end

Now I'm new to ComputerCraft and I cant understand why this wouldn't work...?

Heres my full code thats in my file currently and im getting the error: '=' expected on line 6.

function digforward()
	turtle.dig
	turtle.forward
	turtle.digUp
end
-- ******* end of basic moving functions ******* --

digforward()

All apis, requirres two () parantheses after the function.it tells you, that it think turtle.dig is a variable, but there is no variable in it..

Just remember the parantheses in the end of all your turtle commands.

Did you add the () to the end of each turtle command?

[De Tronazox]

Use () at the end:



function digforward()
turtle.dig()
turtle.forward()
turtle.digUp()
end

[De Tronazox]

The whole code done:

-- Written by Falco.

-- ******* basic moving functions ******* --
function forward()
        turtle.forward()
end

function turnleft()
        turtle.turnLeft()
end

function turnright()
        turtle.turnRight()
end

function digforward()
        turtle.dig()
        turtle.forward()
        turtle.digUp()
end
-- ******* end of basic moving functions ******* --

digforward()

If I'm not incorrect about this, then isn't almost everything a form of a variable?
For example

-- Tables
local myTable = {
  somthing = "nothing",
  someone = "noone",
}
local newTable = myTable

-- Variables
local myVariable = "foo"
local newVariable = myVariable

-- Functions
local function myFunc()
  print("good")
  print("morning")
  print("mr cucumber")
end
local newFunc = myFunc

-- A nice combination, tables + functions
local moves = {
  up = turtle.up
  down = turtle.down
  left = turtle.turnLeft
  right = turtle.turnRight
}

-- Playing though the table
for id,value in pairs(moves) do
  moves[id]()
end

In the example of tables + functions, you could maybe figure out that this is the same way the (for example turtle) functions are grouped.

[Goof]

yes it is, but in the way the OP did it it is not... because he didnt make any variable to that turtle command... he just forgot to make the two parantheses at the end ()

I poroly could tell you the answer,but my computer wont let me open the spoiler!

Or rather, Lua always expects you to do something with a variable. The default assumption is that you are going to assign it a value (from another variable, a function, or an operation). But you can also call them if they contain functions, which is what was intended in this case.

what browser are you using? it probably doesn't support the script used to open the spoiler

EDIT: they are using javascript and of course CSS. if your browser doesn't support those then I really don't know where you got that from

[ChunLing]

Well, most browsers allow for those to be disabled.
