so, i'm tying to make an interaction API for the advanced computer to make making thigns like buttons and centered text etc. a bit easier.
While creating a function for finding the center of the screen, i come across an issue.
I read up on the return statement to see if I was using it wrong and from what I could gather I was using it correctly.

Code:

function term.getCenter()
  local hscreenX = screenX / 2
  local hscreenY = screenY / 2
  do return hscreenX, hscreenY end
end

screenX and screenY are called earlier with

screenX, screenY = term.getSize()

When I test this function out, it returns Y as nil.

Code in test program:

local x, y = term.getCenter()

print(tostring(x))
print(tostring(y))

I placed your code in a test file:

screenX, screenY = term.getSize()

function term.getCenter()
  local hscreenX = screenX / 2
  local hscreenY = screenY / 2
  do return hscreenX, hscreenY end
end

local x, y = term.getCenter()

print(tostring(x))
print(tostring(y))

Exactly as you stated. I got two numbers.

But i didn't
I was supposed to but i only got 1 number, which was the X axis. I never got the Y axis one

edit: When I run it on a normal computer I get 26 then nil

So what in your code differs from the way mine is written?

[Hydrotronics]

the function and the program are in different programs. the function in .IAPI and the test program in test

[KingofGamesYami]

My new setup is:

api file

screenX, screenY = term.getSize()

function term.getCenter()
  local hscreenX = screenX / 2
  local hscreenY = screenY / 2
  do return hscreenX, hscreenY end
end

test file:

os.loadAPI( "api" )

local x, y = term.getCenter()

print(tostring(x))
print(tostring(y))

..still getting two numbers.

for some reason after renaming the function to term.getCentter() it worked...
why? XD

I now name it back and it works....
well this is interesting! case closed?
