stop a certain fork?

[gamer]

hi i just wanna ask if this is possible: lets say i got fork#1 and fork#2 going on at the sametime. let say both are music.playfileloop, is there anyway to stop fork #1 but hav #2 keep going? cuz i kno music.PlayFileStop stops everything

[guruguru]

First off... Music.PlayFileLoop is already a process-type, you don't need to put it in another process. But maybe for this you do...

Hmm... thats interesting. I don't find anything regarding stopping a process. If anybody knows, please let us now :p!

return

[guruguru]

Return? I don't believe that works. That is used for exiting functions/procedures and loops. I just tested it and its a no go.

An idea (not great but meh). If a user decides to stop on song, you stop all the songs, and then you start the songs that havent been stopped again. Just and idea...

lol dats no good either guru

1st off, what are u using process for? The odds are there is a better way to do it with out them unless you are doing somting realy advaced or odd.

Basilky turnings mutlyterading sucks so i do not know if they even put in a way of stoping a process.

but what you could do is somting like:

process:
if flag then
my code
end if
end process

where flag is a boolean var that is set to true to start and then u just turn it to flase to stop it. Kind of a cheap way of doing it but not much you can do if there is no stop comand for a fork and return dose not work.

P.S. if you got a loop in the process u whould have to add exit when not flag in the loop

trust me, return will automatically exit a process or procedure

straight from the turing manual:

Quote:

A return must not appear as a statement in (the outermost level of) a module, nor can it appear in a function.

so anything such as procedures and processes are fine, because they are not a function, or in the outermost level of a module.

code:

var num := 0 process Crap     loop         num += 1         put num         if num >= 100 then             return         end if     end loop end Crap fork Crap

Oh sorry my bad. I thought you meant to use use the fork outside of the process... like you fork it and then return... me so stupide . Asians way works well, except you may want a boolean instead of the counter. When the user types exit or something, than the boolean variables is put to true. The process has a little if statement that executes if the boolean is false.

code:

v var stopProcess : boolean := false process Crap     loop         % play the music         if stopProcess then             return         end if     end loop end Crap fork Crap if %test for user to say he wants to exit% then     stopProcess := true end if

Just a slight mod of AsianS's ingenious code .

ok i think return would be good
btw would it be like:

code:

process play Music.PlayFileLoop ("nameofsong.mp3") if flag then return end if end play

would it still work that way?? cuz it seems its just gonna stay at the Music.PlayFileLoop line forever without checking the flag
whereas in:

code:

process play loop if flag then return end if Music.PlayFile ("nameofsong.mp3") end loop

this would work for sure, but then again i cant use music.playfilestop (something like this command)

[guruguru]

Dam, I tried many versions and for the life of me I can not get it working .

I am lost now... I even tried Music.PlayFile and that dint work. Maybe someone else knows...

[Dan]

That is b/c Music.PlayFile is a bolcking fuction witch means it will not contion on with the code till it is done playing the song.

If you uses Music.PlayFileLoop insted you will not need a process and could stop it at any time in the programe with Music.PlayFileStop.

[guruguru]

We gots that... but he want to play multiple songs at the same time, and then stop a single one.

From Turing documentation...

Quote:

The Music.PlayFileStop procedure is used to to stop all music files currently playing.

That is where the problem resides...

[gamer]

yup, guru gets my point

I dont think that is posable in turing. When i tryed it whould stop playing the 1st song and then play the 2nd.

If you did get that working could u post the code i whould like to see it.

[guruguru]

Ok its not possible then... even HackerDan couldnt get it! :p
A thought just occured, why do you want two songs going at the same time? Is it just curiosity, or do you want to use it in a program? If the latter, can u explain why!?!?
