How To Make a Custom Boot Screen

Hello and welcome to this topic. I'll be showing you how to make a custom boot screen.

Here is the code:

term.clear()
term.setCursorPos(1,1)
print("Computer ID: " .. os.getComputerID())
print("Welcome back, <YourNameHere>!")
print("---------------------------------------------------")

So what this does is clear your screen, and set the cursor position at the top left corner. Then it prints your Computer ID which can be used for rednet purposes I believe. After that it prints a simple welcome message. Finally, it makes a line thing for looks so it looks nice. =P Thats pretty much it!

thank god you didnt put any fake loading screens

Don't hate.

Not much of a tutorial and more of a snippet of code, but not bad for someone new to the mod.

im complimenting him

I have a Hello program that I put on most of my computers that just outputs basic ID information. Two additional things that it does is print out the label, and if it's a turtle it prints out the fuel level.

print("My Computer ID is "..os.getComputerID())
print("My Name is "..os.getComputerLabel())
if turtle then
print("My Fuel level is "..turtle.getFuelLevel())
end

Fake loading screens are indeed lame. there are too many 'loading bar apis' that are just full of sleep commands, so annoying, actually I think I've still got the only real-time loading bar api.

About those nasty progress bars… Even my OS, Backslash uses a "loading progress bar" or whatever, but it's because of the 136 kilobytes of code to load - Anyways, it only lasts for 0.3 seconds or so…

But come on! Found this a bit ago:

print("Loading...")
sleep(0.5)
print("Loaded")

Tableflipped when read that two days ago…

Exactly thats what I'm talking about. Ok if you genuinely have stuff to load, then use a loading bar to show your progress, but never have a fake bar or use sleeps in the process.

If you really really want a want an progress bar you dont have anything to load use sleep that lasts for max 0.5 seconds. But I hate those too.. Just because it just doesnt have a purpose

OK, but don't dare term.write("Loading") then…

Now quit this argument about fake progress bars cuz Lqyqd's gonna kick our a**…

… thats not really a boot loading screen, and most people already know how to do term.clear() … but I think how do to a real loading screen it would be
Feel free to correct me on what ever I did wrong, but I'm pretty sure this would be a real boot screen…

function boot_logo()
  term.clear()
  local boot = {
	term.setBackgroundColor(colors.blue),
sleep(5)
  }
  for i = 1, #boot do
	while false do
print(" ")
break
end
  end
  print("Loading CraftOS, please wait...")
  term.setCursorPos(1,19)
  textutils.slowPrint("_-_-/>_-_-/>_-_-/>_-_-/>_-_-/>_-_-/>_-_-/>_-_")
end
boot_logo()

No boot screen should ever have sleep in it. It just wastes the users' time. If you genuinely have stuff to load, let it load, but don't use sleep.
