Networked Variables

A wrapper for serialization of variables that are to be transmitted over the network stack.

Registering Variables

Variables are registered using the Register method. Pass in the name of the variable for the first parameter. Variables within variables can also be registered, delimited by a period (.) with a maximum depth of 3. Do not register a variable of Class type as that will result in a error. Instead make use of individually registering variables.

Sending and Recieving Changes

Using ScriptRPC, call Write on sending the RPC and Read on recieving the RPC.

Custom Types

Register a Type Converter to create a custom variable type that can be synchronized. Make sure to override the Read(Serializer) and Write(Serializer) methods so only your custom fields are sent, and not the class. Make sure to not set Class types to be synchronized as that will have undefined side effects.

Example

this just an example for arkensor, actual docs later

class DataClass
{
	float m_SomeVariable;
};

class SomeClass
{
	const static int RPC_ID = 1000000;

	private ref DataClass m_DataHolder = new DataClass();
	private int m_SomeIntVariable;

	private ref CF_NetworkedVariables m_NetworkVariables = new CF_NetworkedVariables(this);

	void SomeClass()
	{
		GetDayZGame().Event_OnRPC.Insert(OnRPC);

		m_NetworkVariables.Register("m_SomeIntVariable");
		m_NetworkVariables.Register("m_DataHolder.m_SomeVariable");
	}

	void OnVariablesSynchronized()
	{
		Print(m_SomeIntVariable);
		Print(m_DataHolder.m_SomeVariable);
	}

	void SetSynchDirty()
	{
		ScriptRPC ctx = new ScriptRPC();
		m_NetworkVariables.Write(ctx);
		ctx.Send(null, RPC_ID, true, null);
	}

	void OnRPC(PlayerIdentity sender, Object target, int rpc_type, ParamsReadContext ctx)
	{
		if (id != RPC_ID) return;
		m_NetworkVariables.Read(ctx);
		OnVariablesSynchronized();
	}
	
	void SetSomeClassFloatVariable(float newFloat)
	{
		m_DataHolder.m_SomeVariable = newFloat;

		SetSynchDirty();
	}
	
	void SetSomeIntVariable(int newNum)
	{
		m_SomeIntVariable = newNum;

		SetSynchDirty();
	}
};
