Definition

INT[9] timer

Timer is a global variable, holding ten integers. Each frame a certain value is added to all of them. This value is the difference in time between the start of the last frame and the current frame, in 1/100 seconds.

So when all the timers are never altered, their values will be 1234 when the program has been running for about 12.34 seconds.

Examples

Display how long the program has been running

import "mod_timers"
import "mod_key"
import "mod_text"

Process Main()
Begin

    write_int(0,0,100,0,&timer[0]);

    Repeat
        frame;
    Until(key(_ESC))

End

Used in example: write_int(), key(), timer

This can be done more accurately with the use of frame_time, which is in milliseconds.

Let a process wait for a certain time by calling this function

Function int wait(int t)
Begin
    t += timer[0];
    While(timer[0]<t) frame; End
    return t-timer[0];
End

This can be done without a timer too, as is displayed here.
