Ugh, read THIS.

Now, for my own and other's sanity's sake, imma add the code tags myself before i take a look at it...

Vertical scrolling is actually very simple, since you can place the cursor offscreen.

function vertScroll(text)
  local termX,termY = term.getSize()
  local cursX,cursY = term.getCursorPos()
  local scrollLength = termX-cursX+1 -- calculate visible area
  for i = 1,#text+scrollLength do --loop the length of the text and the length of the visible area
	term.setCursorPos(cursX-#text+i-1,cursY)
	term.write(text)
	sleep(0.2) --scroll speed
  end
end

Working your color scheme into that however is gonna be a bit more complex, i should probably go test this code. gimme a few minutes here.
Edit: I'll add some comments and explainations tomorrow if you want.

function vertScroll(text)
  local termX,termY = term.getSize() -- get terminal size
  local cursX,cursY = term.getCursorPos() --get current cursor position, so it will print to wherever the cursor is currently located
  local scrollLength = termX-cursX+1 -- calculate visible area
  local writeText = string.rep(" ",scrollLength)..text -- pad the text to scroll with enough blank spaces to fill the visible area after the text has scrolled by, to clear it
  for i = 1,#text+scrollLength do --loop the length of the text and the length of the visible area
	term.setCursorPos(cursX-#writeText+i,cursY) --set the cursor offscreen by the length of the string we're scrolling, then subtract how many times we've scroll forward (i)
	local tLines = {} --table containing the strings seperated by color tags, and what color they should be
	for color, line in writeText:gmatch("&(%d)([^&]+)") do -- loop once for every color tag followed by a number (%d) then followed by anything that's not a colortag ([&^]+)
	  tLines[#tLines+1] = {
		string = line, --store the line to the table
		color = color --store the color to the table
	  }
	end
	for i=1,#tLines do --loop once for every entry of the table
	  term.setTextColor(2 ^ tLines[i].color) --set the color
	  term.write(tLines[i].string) --write the text
	end
	sleep(0.2) --pause between each scroll
  end
  term.setCursorPos(cursX,cursY) --return the cursor to it's original position
end

that would be nice thx

[CometWolf]

There, hopefully it's understandable Also i corrected a mistake i realized i made while i was optimizing the code earlier.

[ShadowCreeper559]

can u post the full script so i can copy and past plzz

[CometWolf]

That function is all you'll need.... Just redirect to the monitor like you're already doing, then loop your table through that function, like you're already doing.

[ShadowCreeper559]

i cant seam to get it to display the text

[theoriginalbit]

you know you could have simply asked the author of the script if he made a scrolling version of it (which he did btw).

[Lyqyd]

What have you tried to get it to "display the text"? Does it show any errors when you run the program? What does it do instead of displaying the text?

[CometWolf]

Realized i had to do some minor changes, because you're using hex color codes. Also, i had to remove the newline characters, since they just show up as question marks when you use write anyways.
If you really want multiple scrolling lines at the same time, it shoudl be pretty easily doable with the parallel api. I can show you if you need it.

ok so this works now but it prints the text over the last

[CometWolf]

So, you want this basically?

Well thats why when I wrote this code (link) for CraftAU I made it redirect — using term.redirect — the terminal to the monitor so I could use write not mon.write doing so meant that special characters like newlines and tabs are actually obeyed as opposed to printing ?...
You did vertical scrolling quite a difficult way, you basically reinvented the entire script as well as the wheel, all you needed to add was a term.scroll call with some minor extra logic.

[CometWolf]

Redirect is still possible to use with the function i posted. Just redirect then use function without passing an object, or pass term. term.scroll is horizon.... Oh wait, FUCK! I mixed up vertical and horizontal didn't i? The one i made goes sideways...

except that when you pass a monitor object it invokes mon.write which doesn't allow for special characters...

yeah you did.
