"wantsFullUpdate" & full/half "EntityDescription" about realtimemultiplayernodejs HOT 2 OPEN

Hi morfeus87,

Thank you - and please be sure to make an official fork and put any changes you've made updating the code back into the stream.

I will look at your question in a little more detail later, but yes that should be possible in the framework in fact if you look at the DemoBox2D you can see how I approach this.

The gist of it is that, the framework will automatically call 'createEntityFromDesc' (which you should overwrite for your specific game) on the client side, when it comes across an entity it didn't have in the last frame. On the server side whatever information included it will be passed.

So what I would do - create for your game a GameEntity subclass that is 'smart' about it's first call to 'constructEntityDescription' with a firstUpdate flag or something that only publishes those extra details once.....

From a performance point of view, don't do anything 'too javascripty' such as removing and deleting and recreating the prototype chain after the first update, as this will most likely remove the function as a candidate for optimization by V8...
This talk explains what i mean http://www.youtube.com/watch?v=XAqIpGU8ZZk - lots of good info in there for creating a js multiplayer engine running on v8

I have already created a subclass "PlayerEntity" extending "GameEntity" that has inside a method "constructEntityDescription" as your commented example in "GameEntity".

But the method "constructEntityDescription" is not only called on the server?
Calling this method the first time I set the flag "firstUpdate" to false on this entity, but then the next client will not receive the full version of the entity description. I'm wrong?
I do not understand :(

ps: I had already watched the video on youtube and found it really interesting, along with almost all other Google Video Team and GDC12 video.
Unfortunately, there is already Ammo.js doing 'too much javascript'

ps2: my changes seem fairly home-made even if they are working. However if you want I can make a official fork.

Thank you for your attention!
