Hi this is Vee

I thought timerbased was this
if timer() > oldtimer + 25
runGame()
oldtimer = timer()
endif
However I just found thats not how its done.
Also i'm not using the right way of doing it, but its not working.
The balls don't even move. lol
So here is my code

+ Code Snippet


function ControlBalls()
elapsedTime=(timer()-startTime)/1000
for i = 0 to 9


   ball(i).X = ball(i).X +ball(i).VelX*elapsedTime
   ball(i).Z = ball(i).Z +ball(i).VelZ*elapsedTime

  position object ball(i).ObjNum,ball(i).X,0,ball(i).Z
next i

startTime = timer()

endfunction

Either way works. The method IanM mentioned in that thread is to prevent integer rollover which would mess up the timing in a program. Using the first method rollover would take running your program for 23 days straight. Using the second method (IanM's method) rollover would take running your program for 47 days straight.

+ Code Snippet

` Set the first timer
Oldtimer1=timer()
` Set the startime for the second timer
StartTime=timer()
` Set the second timer
Oldtimer2=timer()-StartTime
do

 ` Check if the first or second timer is up
 if timer()>Oldtimer1+1000 or timer()-StartTime>Oldtimer2+1000
  ` Show the timers
  print "Timer() = "+str$(timer())
  print "Oldtimer1 = "+str$(Oldtimer1)
  print "Oldtimer2 = "+str$(Oldtimer2)
  runGame()
  ` Reset the first timer
  Oldtimer1=timer()
  ` Reset the second timer
  Oldtimer2=timer()-StartTime
 endif

loop


function runGame()
 print "Another second gone by."
 print ""
endfunction

Try making ElapsedTime into a float variable and changing /1000 to /1000.0. This way you are dealing with floats which can have decimals and not integers which can't. Or try any of the other posted suggestions
