Network.AllocateViewID

Description

Query for the next available network view ID number and allocate it (reserve).

This number can then be assigned to the network view of an instantiated object. The example below demonstrates a simple method to do this. Note that for this to work there must be a NetworkView attached to the object which has this script and it must have the script as its observed property. There must be a Cube prefab present also with a NetworkView which watches something (like the Transform of the Cube). The cubePrefab variable in the script must be set to that cube prefab. This is the simplest method of using AllocateViewID intelligently. This get more complicated if there were more than one NetworkView attached to the Cube which is to be instantiated.

var cubePrefab : Transform;

var nView: NetworkView;

function Start() {
	nView = GetComponent.<NetworkView>();
}

function OnGUI() {
	if (GUILayout.Button("SpawnBox")) {
		var viewID = Network.AllocateViewID();
		
		nView.RPC("SpawnBox", 
						RPCMode.AllBuffered, 
						viewID, 
						transform.position);	
	}
}

@RPC
function SpawnBox (viewID : NetworkViewID, location : Vector3) {
	// Instantate the prefab locally
	var clone : Transform;
	clone = Instantiate(cubePrefab, location, Quaternion.identity) as Transform;
	var nView : NetworkView;
	nView = clone.GetComponent.<NetworkView>();
	nView.viewID = viewID;
}
