Game Time

[Allanon]

I am wondering in games such as Unreal, SimCity and others like that, how do the programmers do the time. I mean like in Tetris I assume that a timer would triker then their would be code in that timer that would move the blocks. So what do Unreal, Simcity do. Is it a timer or something else

Thanks

They probably use a gameloop instead of a timer, that is a serie of operations like rendering, keyboard and mouse input, processing all the data needed under a cycle, which repeats on until the game is ended. Timing is then achieved with using for instance Gettickcount api.

Yep, id have to agree with kadaman,
they dont use a timer, they use a loop untill something breaks the loop, but there is also a timere so that the game doesnt take too lonad and to keep track of playing time.

UT has a logger, which logs gane events into a temp file, you can save that log file and look at it.

Do While Not isEventTriggered
  ''some hundreds of lines of code....
  If event == eventTrigger Then
    isEventTriggered = True
  End If
  ''etc... some other bunch of code
  If timeGetTime(now) >= maxTime Then
    isEventTriggered = True
  End If
  ''guess whats next
  ''yup!! u guessed right (more code)

Loop

what i just wrote is not even anywhere near what ut uses,
it is just a sketch of what most devlopers do to keep track of game play... and to have a game that doesnt end as soon as it draws one pixel on the screen.

that would suck.
but this is one way you can do in vb.
