What's the best way to use GetCurrentRealTime() as a timer?

I was thinking that something like this would work...

Float fTime = Utility.GetCurrentRealTime()While fTime < (fTime + 5.0)	fTime = Utility.GetCurrentRealTime()EndWhile

...but the loop doesn't seem to end.

The loop never ends because every time you increase fTime, the (fTime + 5) increases by the same amount. Thus it's basically always checked for X to stop being < X + 5 which is impossible.

Before doing the while loop, create another variable and set it to the current time + 5, then check for that variable instead. See below for example:

Float fTime = Utility.GetCurrentRealTime()Float fTarget = (Utility.GetCurrentRealTime() + 5)While fTime < (fTarget)	fTime = Utility.GetCurrentRealTime()EndWhile

Also, since this will run every single tick, if you don't need it to be precise you should add a 'Utility.Wait(1.0)' after the line that updates fTime inside of the while. However, if this is literally a timer for 5 seconds don't do it. But if you were timing something like 3 minutes, you wouldn't need precision, and could save some on performance.
