Need help with a timer for my game

def seconds_minutes_string(seconds_elapsed)
return '0:00'

end

#It has to have total elapsed time starting at 0:00.

Code:

def seconds_minutes_string(seconds_elapsed)
   return '0.00'
end

Has the same effect as

Code:

SMS = '0.00'

On top of that, it seems (from the absolutely minimal amount of information you provide) that you wish to manage time through string manipulation. Ruby has a very rich set of time functionalities wrapped up in the Time object. Consider the following:

Code:

t = Time.now  # => Tue Nov 17 10:11:18 -0500 2009
# wait a bit
u = Time.now  # => Tue Nov 17 10:11:54 -0500 2009
u - t  # => 35.672565
(u - t).to_s  # => "35.672565"

You can use TIme objects as 'first-class' objects so to speak; they can be added, subtracted, etc...

Not exactly what i am looking for

Thanks for the help but i am trying to make a timer that starts at zero and until the game ends the timer will stop.

Here is a little more information.
I need positive integer of seconds, returns a digital clock string showing the minutes and seconds. Ex.78 seconds will return 1:18

I have no clue on how to do it.

Code:

#!/usr/bin/env ruby

def show_timer(seconds)
    start = Time.now
    while seconds > 0
        elapsed  = (Time.now - start).to_i
        $stderr.puts "Elapsed: %02d:%02d" % [elapsed/60,elapsed%60]
        $stderr.puts "Remain : %02d:%02d" % [seconds/60,seconds%60]
        sleep 1
        seconds -= 1
    end
end

show_timer 20

That should give you a starting point on managing time. It's minimal in that it only handles minutes and seconds; it can double report the times due to truncation to Integer; it is blocking because it sleeps in between reports; and so on.
The output of the above is something like:

Code:

Elapsed: 00:00
Remain : 00:20
Elapsed: 00:01
Remain : 00:19
...
Elapsed: 00:18
Remain : 00:02
Elapsed: 00:19
Remain : 00:01

Found a new way thanks for the jump start

def seconds_minutes_string(seconds_elapsed)
if seconds_elapsed >= 60
minutes = (seconds_elapsed / 60).to_s
return minutes
else
return seconds_elapsed.to_s
end
end
