I would like to have a program which scrolls the words "Tickets Here!" in black font over a white background, with a font size that can be seen well, but isn't too big for the screen (because scale 1 won't cut it). The screen itself is three advanced monitors, connected horizontally. I would like the text to scroll off screen, with a delay of a second or so before you see it scroll again. ..You can edit this time if you want if you think a better delay time would be nicer.
I know enough about computercraft to do nearly everything above except for timing the scrolling.

Please post your current code.

I would rather "borrow" a code from here, since I'm sure 90%+ of the people here could do it to my simple preferences above in a minute flat. The way I did it was messy, so I would much prefer cleaner code since I'm a bit of a perfectionist.

We don't do that in Ask a Pro. Moved to General.

I'm in an exceptionally giving mood today, so I made this for you. However because I like to go above and beyond, I've added quite a few features…
FeaturesSpoiler
- Multiple monitor support
- Multi-sized monitor support (each monitor displays the scroll appropriate for it's size)
- Determines best scale for each monitor
- Automatically detects all connected monitors (including networked peripherals)
- If a monitor is resized will check if it can resize the text (may cause monitors to pause scrolling for a second or so)
- Detects when new monitors are attached to computer or network (may cause monitors to pause scrolling for a second or so)
- Detects removal of monitors on computer or network (may cause monitors to pause scrolling for a second or so)
- Can change the speed at which the text moves (`moveFreq` variable at the top)
- Can change the text displayed on the monitors (`msg` variable at the top)
- Text is black on white background on all monitors
Spoiler
Uncommented (Deployment)
Commented (For Your Learning)Spoiler
Forgot a feature you requested, just added it
EDIT 2: Adding updated screenshot

local monitorSide = "left"
local pos = 6 --I don't know what number this should be
local ts = 2
local TextScale(ts) --Setting it to a unvaraibled number vaule (like 2, using brackets or an equal sign) gives me a nil value error for some reason
mon = peripheral.wrap(monitorSide)
term.setBackgroundColor (colors.white)
term.setTextColor (colors.black)
term.clear()
--Deleted the part of the code involved in scrolling because if was an incorrect infinite loop.

Make sure you read the commented version of my program! It will really help you with your programming!

[macro]Thank you[/macro]
I understand it better now, but much of what you posted was too much for me (such as adding monitors even though I'm only using a 3x1x1 advanced monitor in a small area above a doorway.) :)/> (You really didn't have to go all out, since the aim was for a simple go-right-and-loop sign. :P/>)
I had to set the starting cursor position at one pos. beyond the length of the monitor (from the right) so it would start off screen, and set the left-most value at a pos where the sentence goes completely off screen heading left. After that, I just set the loop-back value to the right-most pos, so it wold loop. I think i am still having trouble with the scale size, even though I used term.TextScale.

There is no `term.TextScale` … it is a function that is on the monitor object, and it is `[monitorObj].setTextScale( [scale] )` where [monitorObj] the the peripheral.wrap of the monitor, and [scale] is the scale you wish to set.

Thanks again. I didn't think using …peripheral.wrap("<side>").setTextScale(<scale>) was going to work initially due to the fact that I clearly didn't know it had to be used together.
