LimitFrameRate by PowerPC603
(Posted 23 years ago)
This code will dynamically delay the execution of your program to limit the framerate.
It is accurate within 1 FPS.
All you have to do, is adding one single function call at the top of your main loop:

LimitFrameRate()

That's all.
Don't forget to place the global variables at the very top of your program.

The default framerate is set to 50.
You can modify it this way:

LimitFrameRate(xxx)

Where xxx is the required framerate. 
Global FrameTime
Global Period

Function LimitFrameRate(FPS = 50)
	If FrameTime = 0 Then
		Period = 1000 / FPS
		FrameTime = MilliSecs()
	EndIf

	; Make sure the framerate isn't above the specified setting
	While (FrameTime + Period) > MilliSecs()
			Delay 1
	Wend
	FrameTime = MilliSecs()
End Function

how about:

FrameTime = CreateTimer(60)

;mainloop

while keyhit(1)=0

WaitTimer(FrameTime)
wend

shorter and simpler.
In the end both are bad, as they block the whole mainloop
Using timebased movement is far better
