Hi
there is a bug in the system.
SoundService/BaseSoundSystem creates its unique instances without
leaving a reference as far as I can tell.
When we tell the sound to stop we don't know which sound to stop...

Here is a proposed fix to that:

Player>>beep: anObject
     "Play given sound or at least beep."
     | sound |
     anObject isString
         ifTrue: [sound _ SoundService default soundNamed: anObject.
             SoundPlayer playSound: sound.
             self costume
                 setProperty: #playingSound
                 toValue: sound. ]
         ifFalse: [SoundPlayer resumePlaying: anObject quickStart: true.
             self costume setProperty: #playingSound toValue: anObject]

Karl,

Thank you very much for your prompt answer.

I'm afraid however it is too much for my level of knowledge.

If I understand you correctly,  you are saying what I want to do  
cannot be done by a regular user.

Somehow someone has to modify the Etoys code and you feel I can do it??

Hi, Carlos and the etoys team.
Some times ago I made this project.

It seems empty but if you see the sound category there is a new tile playsoundUntilDone which dont play another sound
until the first one is finished.

In fact this project contains a changeset,(a modification of Etoys)

If this new tile is juged usefiull by the etoys tile, it could be part of a next update.

You can play with it then reload etoys to revert with standard etoys.
This more an example of adding new tiles fo advanced programmers or for testinng and updating etoys by the team.

If you save a project without the change but using the new tile, you have to load this project before your project.

Regards

Ps The strange name of the project is due to the way the xo attachs a file.

Many thanks to all that responded to my request for help.

This is really a worldwide community!

Each one of the responses received so far have taught me something  
interesting,  has given me a better insight into Etoys.

The original problem is however still unsolved.

I shared a project:

http://squeakland.org/showcase/project.jsp?id=7829

which is a translation of another project,  used in the Virgin Islands  
pilot project.

You may see one of the suggestions for improvements was to correct a  
problem:

If the user changes pages too fast, the sound in the new page starts,  
whether or not the sound on the previous page has ended.

We hear both,  one on top of the other.

Karl mentions the problem is the sound to be stopped cannot be easily  
identified.

My problem would be resolved if I could stop all sounds,  then I would  
have silence to start the sound for the new page.

The other answers bring very interesting possibilities which I was not  
aware of but, again,  I don't seem to be able to apply to the problem  
in front of me.

Thanks again,

Carlos Rabassa

Carlos,

you can make yourself a tile that stops all sounds.

1) make a new script, switch it to "textual" mode using its white menu button:




2) replace the "^self" line in the script with "SoundPlayer stopPlayingAll", then press Cmd-S to save it:




3) use the new tile in your own script:




Explanation:

"SoundPlayer stopPlayingAll" is an expression from the "Squeak" programming language underlying Etoys. By switching a script to "textual" mode you can enter arbitrary statements. This is useful to access functionality not provided by Etoys tiles directly.

Carlos,

I see you used the "start script" tile even for scripts that should only run once (and you pause the script after its first run). A much simpler and usually preferred way is to simply drop one script's tile from the viewer into another script.

Bert,

thank you very much.

Tried your solution.

It works perfectly.

Now I have to incorporate it to some projects.

Will let you know about my progress.

Thanks!!

Carlos
