How do I add gravity to my object, and how do I fix my network problem?

Questions & Answers
1

Hello,

I am trying to create a small game, to start with, in Unity3D. This is supposed to be a basic game that works over a network. So far, I have my network working, and I had it where one player could see another player moving, and vice versa.
Here are my problems:

  1. I don’t know how to add gravity to my cube (player). Using Rigidbody has not worked, because it’s caused my cube to fly all over the screen.
  2. I don’t know how to fix the problem I am having with my network. At the moment, when one player moves his or her character, it actually moves the other player’s character, and vice versa.

You can view [this YouTube video][1] to see my problems in action.

Also, when I add gravity to the player/character in another test game (not the one in the video), it tips over based on the slope of the terrain. I want the character (which is a 2x1x1 cube) to stand upright, regardless of the terrain setting.

Here is some code from the game that is shown in the video:

Movement.js Code:

var speed:float = 0.2;
var rotateSpeed:float = 5;

function Start(){
	if(!networkView.isMine)
	{	
		enabled = false;
	}
}

function Update(){
		if(Input.GetKey(KeyCode.UpArrow))
		{
			transform.Translate(Vector3.forward * speed);
		}
		if(Input.GetKey(KeyCode.DownArrow))
		{
			transform.Translate(Vector3.back * speed);
		}
		if(Input.GetKey(KeyCode.RightArrow))
		{
			transform.Rotate(Vector3.up * rotateSpeed, Space.World);
		}
		if(Input.GetKey(KeyCode.LeftArrow))
		{
			transform.Rotate(Vector3.down * rotateSpeed, Space.World);
		}
}

NetworkManagerScript.js Code:

var playerPrefab:GameObject;
var spawnObject:Transform;

var gameName:String = "CJay7_Test";

private var refreshing:boolean;
private var hostData:HostData[];

private var buttonX:float;
private var buttonY:float;
private var buttonWidth:float;
private var buttonHeight:float;

function Start(){
	buttonX = Screen.width * 0.05;
	buttonY = Screen.width * 0.05;
	buttonWidth = Screen.width * 0.15;
	buttonHeight = Screen.width * 0.15;
}

function startServer(){
	Network.InitializeServer(32, 25001, !Network.HavePublicAddress);
	MasterServer.RegisterHost(gameName, "Test Game", "I am creating a test game from a tutorial. 'http://vimeo.com/33996023#'");
}

function refreshHostList() {
	MasterServer.RequestHostList(gameName);
	refreshing = true;
}

function Update(){
	if (refreshing)
	{
		if (MasterServer.PollHostList().Length > 0)
		{
			refreshing = false;
			Debug.Log(MasterServer.PollHostList().Length);
			hostData = MasterServer.PollHostList();
		}
	}
}

function spawnCharacter(){
	Network.Instantiate(playerPrefab, spawnObject.position, Quaternion.identity, 0);
}

//MESSAGES
function OnServerInitialized(){
	Debug.Log("Server Initialized");
	spawnCharacter();
}

function OnConnectedToServer(){
	spawnCharacter();
}

function OnMasterServerEvent(mse:MasterServerEvent){
	if (mse == MasterServerEvent.RegistrationSucceeded)
	{
		Debug.Log("Registration Succeeded");
	}
}

//GUI
function OnGUI(){
	if(!Network.isClient && !Network.isServer){
		if (GUI.Button(Rect(buttonX, buttonY, buttonWidth, buttonHeight), "Start Server"))
		{
			Debug.Log("Starting Server");
			startServer();
		}

		if (GUI.Button(Rect(buttonX, buttonY * 1.2 + buttonHeight, buttonWidth, buttonHeight), "Refresh Hosts"))
		{
			Debug.Log("Refreshing");
			refreshHostList();
		}
		
		if (HostData)
		{
			for (var i:int = 0; i < hostData.length; i++)
			{
				if(GUI.Button(Rect(buttonX * 2 + buttonWidth, buttonY * 1.2 + (buttonHeight * i), buttonWidth * 3, buttonHeight * .5), hostData*.gameName))*

  •  		{*

_ Network.Connect(hostData*);_

I have solved both of my issues. I will try to remember to post my solutions tomorrow.
