Use the Timer() command:
Sync On : Sync Rate 0
start# = Timer()
delay = 1000
timeallowed = 60
Do
Cls
countdown# = Timer()
If countdown# - start# >= delay
delay = delay + 1000
EndIf
Print (timeallowed - Int((countdown# - start#)/1000));" Seconds remaining..."
If (timeallowed - Int((countdown# - start#)/1000)) <= 0
Cls
Print "Game Over..."
Print "Press Any Key To Exit."
Wait Key
End
EndIf
Sync
Loop
And just change the value of
delay for different count-down values, eg, for a five second count-down, have
delay = 5000.
Also to change the start amount of the count-down, change
timeallowed to whatever you want...
Hope I Helped...
