Ok ive been messing around with making a new function that has named timers but it keeps throwing an error :l
heres the code:

Spoiler

fps = 20
function startTimer(name,time)
table.insert(timers,{name,time})
end
function updateTimers()
if #timers > 0 then
  for i = 1,#timers do
   timers[i].time = timers[i].time-(1/fps)
  end
end
end
function checkTimerOutput()
timersDone = {}
for i = 1,#timers do
  if timers[i].time <= 0 then --error here
   table.insert(timersDone,timers[i].name)
  end
end
if #timersDone > 0 then
  os.queueEvent("Timer",timersDone)
end
end
function main()
term.clear()
secretfunctionname:P.print(1,2,"hello","hi!","boom")
startTimer("ben",3)
event, name = os.pullEvent()
term.clear()
secretfunctionname:P.print(1,1,event,name)
loopBreaker = true
end
k = 0
function update()
k = k+1
checkTimerOutput()
updateTimers()
sleep(1/sky.clock.fps)
secretfunctionname:P.write(1,1,k)
end
while loopBreaker ~= true do
parallel.waitForAny(update,main)
end

I really dont know whats wrong

Can you please post the error too... Is it attempt to call nil?

[KaoS]

you are using the table "timers" when you have not defined it as a table. add

local timers={}

to the top of your code

[Exerro]

this isnt the whole code btw...im making a library thing like love2d and the table timers is defined at the top (forgot to add that into the code here)
all of the "clock" library is here:

Spoiler

local args = {...}
sky.clock = {}
sky.clock.fps = 20
sky.clock.timers = {}
function sky.clock.startTimer(name,time) -- wont work
table.insert(sky.clock.timers,{name,time})
end
function sky.clock.setFPS(fps)
sky.clock.fps = fps
end
function sky.clock.updateTimers() -- broken
if #sky.clock.timers > 0 then
  for i = 1,#sky.clock.timers do
   if sky.clock.timers[i].time ~= nil then
	sky.clock.timers[i].time = sky.clock.timers[i].time-(1/sky.clock.fps)
   end
  end
end
end
function sky.clock.checkTimerOutput() -- broken
sky.clock.timersDone = {}
for i = 1,#sky.clock.timers do
  if sky.clock.timers[i].time ~= nil and sky.clock.timers[i].time <= 0 then
   table.insert(sky.clock.timersDone,sky.clock.timers[i].name)
   sky.clock.timers[i] = nil
  end
end
if #sky.clock.timersDone > 0 then
  os.queueEvent("skyTimer",sky.clock.timersDone)
end
end

the error is something like attempt to compare nil with number

[KaoS]

we need the full code to assist you...

[Exerro]

all code here...the timer stuff is in BlueSky/clock.lua test.lua is where it runs BlueSky.lua is the code that puts it all together

We also would prefer to have the line number of the error. The error message should specify which string (file) cause the error on what line. A tip, [Bios]:666 (or whatever) is the clever program that notices your mistakes, it is not the source of the mistake.
