Hi, the server that I am a mod on right now has a staff list board, the code used for it now is this.


local tText = {
"---Owner---",
"name",
" ",
"---Administrator---",
"name",
" ",
"---Moderators---",
"name",
"name",
"name",
"name",
"name",
"name",
"name",
"name"

}
local sSide = "left"
local nTextSize = 1
local function printCenter(mon, t)
local w, h = mon.getSize()
local y = math.floor((h / 2) - (#t / 2)) - 1
for i, line in ipairs(t) do
local x = math.floor((w / 2) - (#line / 2))
mon.setCursorPos(x, y + i)
mon.write(line)
end
end
local mon = peripheral.wrap(sSide)
mon.setTextScale(nTextSize)
printCenter(mon, tText)

Problem is now, I need to add a couple more people, but the list is too long and it cuts off some of it. So I was thinking of maybe making 2 separate columns for the moderators list, but I really don't know how to.

I could offer a suggestion on how to do this, but it wouldn't be using tables is that ok?

Not really sure what you mean but I am using a big monitor attached to a computer, there is also no http enabled.

Tables are really the best way to go about this. What this program does is write all of the items in tText until it reaches then bottom of the screen, whereupon it adds 20 to the xValue which it is writing at and resets the yValue to 1.


local monitor = peripheral.wrap("left")
local yValue = 1
local xValue = 1
local xSize, ySize = monitor.getSize()
local function writeAt(text)
  monitor.setCursorPos(xValue, yValue)
  monitor.write(text)
  if yValue == ySize then
	 yValue = 1
	 xValue = xValue + 20
  else
	 yValue = yValue + 1
  end
end
for i=1, #tText do
  writeAt(tText[i])
end

Edit: Added monitor support and moved the next column over more.

Sure. You want it centered in the column I'm guessing? Try this.


local monitor = peripheral.wrap("left")
local xSize, ySize = monitor.getSize()
local xValue = 0
local yValue = 1


local function writeAt(text)
  monitor.setCursorPos((10+xValue)/2-(#text/2), yValue) --Half of the column size + the starting xValue - half of the text length
  monitor.write(text)
  if yValue == ySize then
         yValue = 1
         xValue = xValue + 20
  else
         yValue = yValue + 1
  end
end

for i=1, #tText do
  writeAt(tText[i])
end
end

If the monitor is big enough then change the monitor.setCursorPos() to this:

monitor.setCursorPos( (xSize - #text)/2, yValue)

That won't print it centered in the column though, just centered in the xSize area. And I think you messed up a bit with the #text - xSize part because the length of text will always be shorter than xSize, meaning that you'd have a negative number.

function cPrint( text )
	    -- prints in the centre of the current line.
	    -- Z is just their to stop errors
	    local z,y = term.getCursorPos()
	    local x,z = term.getSize()
	    local textL = string.len(text)
	    local xCor = x/2 - textL/2
	    term.setCursorPos(xCor, y)
	    print(text)
end

This is what I use to have the text begin from the centre…. Taken from my GUI functions

Could you tell me what is on line 42? I just tried the code and it works fine for me. Just in case the code in the code box code box got fudged somehow, here it is again.


local yValue = 1
local xValue = 1
local xSize, ySize = term.getSize()
local function writeAt(text)
  term.setCursorPos((10+xValue)/2-(#text/2), yValue)
  term.write(text)

end

You have a similar problem to the one Remix had; you're still printing from the center of the page, not the column.

Ahh. Now looking at the code I see that extra end there. Yeah remove that and it should be good to go.

Ok, it is now showing like this.

Now, how do I move the whole thing to the middle now?

Well, he asked how to center the code so I showed him how to center it on the screen, but like I said, if the monitor is big enough.

Edit: Just saw your post now, change


term.setCursorPos((10+xValue)/2-(#text/2), yValue)

to

term.setCursorPos((xSize - #text)/2, yValue)

Okay I'm confused now. I thought that there were too many entries for it all to fit on one line. The issue with just printing it centered is that if it continues onto the next line, some text will be overwritten.

Edit: OP's problem is solved so nevermind

That was the main issue, but I put your code in and it worked, but it was not centered.

Yes my code centres it as you wanted… Just now do cPrint("NAME < FEW SPACES> NAME") You can make it appear like coloums by just putting spaces….
