Wouldn’t it be more flexible if you allowed both a number *or* a function pointer as the third template parameter to CNetVariable? This way, you could have fine control over how/when updates to the variable get propagated over the network.

But I wanted to have network variables in a much simpler class, where I can use ints and floats the same way I would normally do. So I can use ++ and -= and assign/comparison signs on them. That’s why I made it separate from my usual network object class.

Andrew: Ah of course, I remember Source having that. I’ll check it out.

Blacksheepboy: I don’t know what I would use it for, in-game c++ parser for scripts?

Softpedia and sourceforge nabbed copies of his latest version:

Although I lack all means, all skills to use this product, it still fascinates me. What I did do that introduced me to the project was help design the simple icons. If ever you are curious, and have the spare time (maybe during a lull in the Link Dead production), look into the product behind http//www.lrstar.org. You did mention something about compilers, and this fella behind lrstar has been working solo on this project for the last 32 years.

Once again, this stuff is way beyond me, but from what I’ve seen, this guy is dedicated to making it “the best in the world”. You might be interested.

Maybe check out how Source SDK does it?

– A SendTable member
– A Serialize method (public access to sendtable)
– A Deserialize method (public access to sendtable)
– An entity ID

To begin with, I use an entity dictionary (“edict”) to properly identify and construct specific network classes across the network. I’ve implemented this using self-registering template factories (if you want a code sample, I’ll cook something up later), which in the end serve to identify classes by an 8-bit integer. (I.e., I can do something like CPlayer::GetEdict() and receive “0”, and do CEdict::CreateInstance(0) and receive a new CPlayer instance.) This is mainly used for construction across the network.

To uniquely identify different entities, they all have a entity/instance ID – all instances have a globally unique 16-bit integer.

Since all network entities have a sendtable class, I can define certain variables for which to provide network serialization in the appropriate constructor.

Upon serialization of the CSendTable, only variables which needs to be sent are serialized – this allows for delta updates, updates ever X seconds. It could all be specialized and customized thanks to the fact that there is a base network variable class.

A short example:

What about ID’s how does the client know what actual variable it should update?
