Hello all,
I used code of the textchat example which I rewrote for my own use.
What this does now:
It makes an sharedObject on connect of an client (if the so does not exist yet).
On update of the So all the clients which are connected recieve the updated So with no problem.
Now I’d like to make the sharedObjects persistant.
This is where i’m stuck now…
If I make the shared object persistant with the appInstance.getSharedObjects(true);
Then suddenly the connected clients doesnot recieve any updates anymore.
I read a lot posts about persistance but im still missing a piece of the puzzle.
My final goal is that i can store a few presets on the server and maintain and recall them anytime.
My So’s stores x and y coordinates, url’s, rotation information ect…
Can somebody shine his light on my code?
Thx in advance,
Marco
