Thread: Java 'tag' variables for synching with a server.

Hi all,

I'm still in the stages of learning Java, and I'm constantly finding new challenges to improve my skills

Anyway, I'm trying to achieve something of which I'm not quite sure if it can be done.
It is for a simple online game, in which the player constantly sends it's position to the server.
No problems there, everything works fine, however I was thinking of a system that would make my life easier, so I made a new class:

public class OnlineObject {

Each object that is in synch with the server extends this class.
Now what I'm trying to do is create a system that automatically sends all the variables to the server that needs to be synched.
However I have no idea how to find out what variables an object has, and how to make a system that only sends certain variables of that object.

I really hope that somebody could point me in the right direction.
If my problem isn't clear please ask, I found it really hard to put my thoughts on paper, so I understand if it comes accross as a bit 'blurry'.

Look at the Observer/Observable and Callback design patterns to see if those suit your needs.

Maybe this will help you.
