Good Clock Program

Startup Code

shell.run("monitor","right","clock")

Clock Code

term.clear()
term.setCursorPos(1,1)
z=true
while true do
shell.run"time"
sleep(0.75)
term.setCursorPos(1,1)
term.clear()
end

this is a pretty good clock and it auto-updates its self when you log off and back on

Although (No offence) this program is practically completely useless, you could improve it by removing some of the clutter.

while true do term.clear() term.setCursorPos(1,1) shell.run("/rom/programs/time") sleep(0.75) end

Also why is z even declared? I can't see where you use it.

just a pointer, you could do

while true do
term.redirect(peripheral.wrap(side))
shell.run("clear")
shell.run("time")
sleep(1)
end

Edit: Why do you declare z and call term.clear and term.setCursorPos at the start why not move them to the top of your while loop

Don't put a redirect in a while loop without balancing it with a restore.

It WOULD be pretty funny to see someone trying to debug that one… "I've run term.restore() 500 times and it's STILL stuck on the monitor!"

There was a thread in AaP about that I little while ago that I helped with, multiple redirects but only one restore. One of my old programs also had that edge case where it would occasionally get stuck on a monitor too.

I wrote a pretty simple clock program free for anyone to use, please give comments on where i can reduce code.

local time = os.time()
local moniter = peripheral.wrap('side')
local function getTime()
   moniter.clear()
   moniter.setCursorPos(1, 1)
   moniter.write(textutils.formatTime(time, bTwentyFourHour))
   sleep(0.75)
end
while true do
   getTime()
end

errr getTime is just writing the same thing over and over move time = os.time() into your function

so something like this?

local moniter = peripheral.wrap('side')
local function getTime()
   time = os.time()
   moniter.clear()
   moniter.setCursorPos(1, 1)
   moniter.write(textutils.formatTime(time, bTwentyFourHour))
   sleep(0.75)
end
while true do
   getTime()
end

Hello guys, here is my attempt to code another clock program.
Please tell me what you think about since I'm kind of new to lua therefore any advice/criticism is welcome.

function showTime (display)
  display = display or term
  while true do
	local timer = os.startTimer(1)
	local event, id = os.pullEvent("timer")
	if id == timer then
	  display.clear()
	  display.setCursorPos(1, 1)
	  display.write(textutils.formatTime(os.time(), true))
	end
  end
end

I know this is an old thread but this was my attempt at a clock for a single monitor, no terminal redirects either.</p>

side = ...
print(side)
mon = peripheral.wrap(side)
mon.clear()
while true do
  os.startTimer(1)
  local event = os.pullEvent("timer")
  mon.clear()
  mon.setCursorPos(1,3)
  mon.write(textutils.formatTime(os.time()),true)
end

I just saved that as clock, called it with &amp;quot;clock top&amp;quot; and it runs on the top monitor. Presumably would work with network attached monitor too


EDIT: Anyone else had issues with the comments suddenly deciding to be posted as plain text HTML?

Like 6677, I know this is an old thread but I've made my own clock for my server spawn and I'm happy to share it with you :)/>

m = peripheral.wrap("side")
m.clear()
m.setTextScale(2)
m.setTextColor(colors.red)
function updateClock(m)
  while true do
	mcT = os.time()
	m.setCursorPos(1,5)
	m.clearLine()
	m.setCursorPos(6,5)
	m.write(textutils.formatTime(mcT))
	m.setCursorPos(1,2)
	m.clearLine()
	m.setCursorPos(3,2)
	m.write("Jour "..os.day())
	sleep(0.1)
  end
end
updateClock(m)

Just in case, you need to replace "side" at lign 1 by the side where your monitor is AND you need to have Advanced stuffs (Computer, Monitor)

PS: I use a 3x2 monitor but you can have a smaller one or a bigger one, just check for "text size" at lign 3, "text color" at lign 4 and "text placment" at lign 10 and 14 :)/>
