Hello all together,
i will be happy if someone helps. What is a good method to play sounds exactly, in equal intervals. Values up to 0.1 seconds are ok for me. At this moment i work with timer() to control the intervals. Is timer() or getmilliseconds() the better way? Or is it equal?
To control the sounds, i use the following lines:

timea# = timer()
if mb1 = 1 and getspritecollision
flag = 1
timeb#=timer()
endif

if flag = 1 and soundplaying = 0 and timea#>timeb#+0.2
playsound (1,70)
soundplaying=1
endif
if flag = 1 and soundplaying = 1 and timea#>timeb#+0.4
playsound (2,70)
soundplaying=2
endif

And so on. Is this a good method or is there an easier or better way? Thank you for your help.

Using Timer() is fine, they both should be equal. However, Timer() uses floating pointer numbers which will loose accuracy the longer the program is running. But it shouldn't be a problem under normal usage.

You can reset the timer at regular intervals to maintain accuracy.

If all you want is to repeat the same sequence of sounds every n milliseconds, then by far the best solution is using some audio-software to create that pattern and save it as a single sound file. Then you'll trigger this sound file (and stop it) whenever you like. This is by far the best solution.

If you still want to try it "the hard and imperfect way" you could use

do
if timer*1000>"n"
"perform this operation"
reset timer
loop

This should do the operation close to every "n" milliseconds if I am not mistaken.

Thank you for your answers. All post´s have give me some ideas to test. At the moment if i use intervalls with 0.2 it sounds good enough.

Since you're only concerned about tenths of seconds(.1), and not milliseconds(.001) I wouldn't think you would have a problem.

Are you noticing something wrong?
