Hello Rick and Vcard ,

Years ago I had a piano on blaxxun , shared .

Yesterday a friend asked me to get one for MixED .

I will add that one , not shared

http://mixed3d.free.fr/paintingweb/amir/galeriesamir/piano/pianoamir.wrl

then I went here on your forum to try a shared way ,

and I made that test

http://www.odisseia.univ-ab.pt/ABNet2/3dchat.aspx?x3durl=http://mixed3d.free.fr/paintingweb/amir/galeriesamir/piano/abnettestson.wrl


But with my wife on a second puter ,
it seems not working shared

Alain,

Your code looks ok. You might want to try copying the
file protos.wrl to your machine and changing your
extern definition. Sometimes the delay in loading extern protos
causes issues.

We can try it online and see what happens.

ah sorry , I didnt got your answer

I checked yesterday that I have the "notify me the answers" yes,

but it can"t be saved , the submit does nothing ..

it stays blank , so by default I guess that means "no" ...
humm

well ,

thanx ,

I hosted the protos for
http://mixed3d.free.fr/paintingweb/amir/galeriesamir/piano/abnettestson2.wrl


and I tested with my whife ,

http://www.odisseia.univ-ab.pt/ABNet2/3dchat.aspx?x3durl=http://mixed3d.free.fr/paintingweb/amir/galeriesamir/piano/abnettestson2.wrl

but same result ...


what is strange to me , as I was used to have that on blaxx ,

is that with the SharedZone of blaxx ,
normaly when you clik with that ROUTE ,
you get no event
( so no sound )


you get it only on the chat .

and here , cliking on the wrl I get the sound ..

normal ??

Hi,

Very nice piano Smile

Shared events in ABNet are similar to blaxx.
You only forgot to define ABNetZone

DEF ABNetZone ABNetZone { ...

The rest you did well Smile

Your example is working here:
http://vrmlworld.net/frameset.php?x3durl=http%3A%2F%2Fwww.odisseia.univ-ab.pt%2FABNet2%2Fdemos%2Fabnettestson2%2Fabnettestson.wrl&title=Alain+Shared+Sound

aaaaaaaaaaahh !! OKKKKKK !!!

I never thought it was necessary , btw it is not referenced ,

just

DEF SHARED_EV1 SharedEvent { name "se1" type "SFTime"

is ...


But OK , je te crois Smile

and I will test it with my wife Smile

on the other hand I still free strange that the wrl ( yours ) still plays the sound ( when not in chat )


But merci beaucoup ...

Yes the shared ABNet proto plays the animations in single mode too.
In blaxxun it was annoying to see the shared animations "broken" when the server was down, and it was often Sad
I think having the shared animations work even in single mode is better and more standard. Your world's behaviour is less dependent on this or that server. Don't you agree? Very Happy

Rick,

I was wondering if it were possible to add an SFNode event to SharedEvent or if is way to much work? lol

Just curious about this and i realize you are very busy these days so if that is too far out there then disregard my silliness. Razz

SFNode is possible, but really tricky to do.

Simply converting a node to a string doesn't work, I tried that. You have to read the contents of the different fields and make some ling string up bit by bit.

Best way for now is to send the node as a string, then use CreateVrmlFromString on the returned result.

I was talking with VC and we were discussing how cool it might be to be able to make a world using the drophandler proto from BM. That is the context in which i was inquiring about the sfnode sharedevent. The proto sends an SFNode event is why i was asking. I thought about the possibility of sending it as a string and then feeding the string back into the sfnode eventIn but man that could get lengthy lol. Maybe it's just one of those things that is pretty hard to do. lol
