Post by: Hotshot on March 16, 2007

Code: [Select]

Graphics 640,480,16,2

Time=MilliSecs()
Repeat

Should work, dunno I don't have Blitz on this computer :D

Code: [Select]

Graphics 640,480,16,2
SetBuffer BackBuffer()

Time=MilliSecs()
Repeat

Text 0,0,MilliSecs()-time
Flip
Cls
Until (MilliSecs() - Time) >= 20000 ; 20 seconds

@Hotshot you just got the < the wrong way round ;)

Code: [Select]

Graphics 640,480,16,2
SetBuffer BackBuffer()

Time=MilliSecs()
Repeat
Text 0,0,time
Until MilliSecs() > Time + 20000 ; 20 seconds

I nearly got it right but thank for helping and also I put
delay(1000) to slow the timer down.

that great

cheers

When you put your delay of 1000 in you will slow your whole program down..


There is also a problem with the code you and paul posted, you won't be able to see the timer because you never cleared the screen...

Use this instead; (not tested but if I don't know how to write a blitz program by now I should be ashamed :P )

Code: [Select]

;----------------
; Open Screen;
;----------------

Graphics 640,480,16,2
SetBuffer BackBuffer()

Global Time=MilliSecs()

;----------------
; Main Loop Repeats until 20 seconds is over or escape pressed.
;----------------

Repeat

clock()
Flip
Cls

Until (MilliSecs() - Time) >= 20000 Or KeyDown(1)

;----------------
; Display How Many Seconds Have Passed.
;----------------


Function clock()
elapsed = (MilliSecs()-time) /1000
Text 0,0,elapsed
End Function

Damn shockwave beat me to it....

And yeah, if you are using delay(1000), then it will also delay the rest of your program so you will only get 1 frame per second.

By dividing the time by 1000, you can chop off the milliseconds :)

Thanks :)

Lol, sorry Mike. I didn't realise you were replying to him.
Let's hope that Hotshot saw the code otherwise he will have an intro with an.. erm.. Choppy frame rate ;)
