场景转换：
var screenbutton: boolean;
function Start(){
DontDestroyOnLoad(this);
screenbutton = true;
}
function Update () {
if(Input.GetKeyDown(KeyCode.Escape)){
screenbutton = true;
}
}
function OnGUI(){
if(screenbutton==true)
if(GUI.Button(Rect(Screen.width/2-380,Screen.height/2-190,60,50),"Scene1")){
print("You click Scene1");
Application.LoadLevel (1);
screenbutton = false;
}else if(GUI.Button(Rect(Screen.width/2-380,Screen.height/2-130,60,50),"Scene2")){
print("You click Scene2");
Application.LoadLevel (2);
screenbutton = false;
}else if( GUI.Button(Rect(Screen.width/2-375,Screen.height/2-0,50,50),"Quit")){
print("You click Quit");
Application.Quit();
}
}
心得：
场景转换时，这个程序贴在按钮界面场景中。在Build Setting（导出）（在File下）菜单中加入所需场景。

0为按钮界面。可以无限增加场景。
}else if(GUI.Button(Rect(Screen.width/2-380,Screen.height/2-130,60,50),"Scene2")){
print("You click Scene2");
Application.LoadLevel (2);
screenbutton = false;
复制此段程序并做修改。

运动控制键：上下左右
var TankSpeed:int = 20;
function Update () {
if(Input.GetKey(KeyCode.W)){
print("go");
transform.Translate(Vector3.forward * Time.deltaTime * TankSpeed);
}else if(Input.GetKey(KeyCode.S)){
print("go back");
transform.Translate(Vector3.forward * Time.deltaTime * -TankSpeed);
}else if(Input.GetKey(KeyCode.A)){
print("turn left");
transform.Rotate(Vector3.up * Time.deltaTime * -TankSpeed);
}else if(Input.GetKey(KeyCode.D)){
print("turn right");
transform.Rotate(Vector3.up * Time.deltaTime * TankSpeed);
}
}
需要放在第一视角的物体或者摄像机上。

加天空背景：
菜单栏Component下的Rendering下的Skybox。将他加在所需场景的摄像机上，选择所需的天空。运行时自然出现。

各种按钮汇总：

鼠标碰触后显示说明文字。
function OnGUI () {
GUI.Button (Rect (0, 0, 100, 20), GUIContent ("Click me", "This is the tooltip"));
GUI.Label (Rect (0, 40, 100, 40), GUI.tooltip);
}

多项选择，以上都选择。
var allOptions = true;
var extended1 = true;
var extended2 = true;
function OnGUI () {
allOptions = GUI.Toggle (Rect (0,120,150,20), allOptions, "Edit All Options");
GUI.enabled = allOptions;
extended1 = GUI.Toggle (Rect (20,70,130,20), extended1,
"Extended Option 1");
extended2 = GUI.Toggle (Rect (20,90,130,20), extended2,
"Extended Option 2");
GUI.enabled = true;
if (GUI.Button (Rect (0, 160, 150, 20), "Ok"));
print ("user clicked ok");
}

鼠标碰触第一个按钮有解释，鼠标碰触第三个对话框有解释。碰第二个没有解释。
function OnGUI () {
GUI.Box (Rect (5, 300, 110, 75), GUIContent ("Box", "This box has a tooltip"));
GUI.Button (Rect (10, 230, 100, 20), "No tooltip here");
GUI.Button (Rect (10, 200, 100, 20),
GUIContent ("I have a tooltip", "The button overrides the box"));
GUI.Label (Rect (10,260,100,40), GUI.tooltip);
}

半透明，说明性文字对话框。无选择。
function Update () {
}
function OnGUI () {
GUI.BeginGroup (new Rect (Screen.width / 2 - 400, Screen.height / 2 - 300, 800, 600));
GUI.Box (new Rect (0,0,800,600),"This box is now centered! - here you would put your main menu");
GUI.EndGroup ();
}

滚动条，选择按钮。可以放多个按钮并且节省位置。
function Update () {
}
var scrollPosition = Vector2.zero;
function OnGUI () {
scrollPosition = GUI.BeginScrollView (Rect (10,400,100,100),
scrollPosition, Rect (0, 0, 220, 200));
GUI.Button (Rect (0,0,100,20), "Top-left");
GUI.Button (Rect (120,0,100,20), "Top-right");
GUI.Button (Rect (0,180,100,20), "Bottom-left");
GUI.Button (Rect (120,180,100,20), "Bottom-right");
GUI.EndScrollView ();
}

循环的字幕。
var letterPause = 0.2;//定义每个字出现的时间间隔
var sound : AudioClip;//打字机的声音
private var word;//存储你打字机效果想要输出的字的变量
private var Text : String = "My name is Ray Yang.Keep it in your heart!";//你希望打字机效果输出的字

function Start () {
word = Text;//把你输出的字先赋值给word
Text = "";//把你要显示的字先抹除，以便你可以在最初显示的时候显示为空，当然你也可以加上其他字，让他先显示，打字机效果打的字会显示在这个后面
yield WaitForSeconds (2);
TypeText ();
}
function OnGUI () {
GUI.Label (Rect(150,15,250,25),"Please answer my question,who am I?");
GUI.Box (Rect(150,40,250,25),Text);
}
function TypeText () {
for (var letter in word.ToCharArray()) {//做一个循环，定义一个变量letter逐次等于word中的每一个字符
Text += letter;//把这些字赋值给Text
if (sound)//控制声音，出现一个字，发一个声音
audio.PlayOneShot (sound);
yield WaitForSeconds (letterPause);
}
}
function Update () {
if(Text == word){
Text="";
TypeText();
}
}

主板游戏系列程序：
CameraMoveRotate（第一视角界面场景自控程序）
使用时点击鼠标右键可以自由转换视角。同时点击AWSD键可以控制前进后退，向左向右。C#程序。
using UnityEngine;
using System.Collections;

/// MouseLook rotates the transform based on the mouse delta.
/// Minimum and Maximum values can be used to constrain the possible rotation

/// To make an FPS style character:
/// - Create a capsule.
/// - Add a rigid body to the capsule
/// - Add the MouseLook script to the capsule.
/// -> Set the mouse look to use LookX. (You want to only turn character but not tilt it)
/// - Add FPSWalker script to the capsule

/// - Create a camera. Make the camera a child of the capsule. Reset it's transform.
/// - Add a MouseLook script to the camera.
/// -> Set the mouse look to use LookY. (You want the camera to tilt up and down like a head. The character already turns.)
