写在前面————
哈哈， 开始做关于脚本热更新的第一个例子了，鉴于本人还是个没毕业的学生，所以不足之处还希望大家包涵~~~~~~
注意：
1.本文章是用Space Shooter(Unity3d官方的小游戏)做的例子
2.Space Shooter源码和Scorpio-CSharp 的下载链接我会放在文章最后面
3.如有任何疑问，请加群245199668
正文
1.新建项目，把下载好的Space Shooter导入Unity中， 打开Done_Main场景，
2.下载Scorpio-CSharp，你会得到几个文件：Scorpio，ScorpioDemo，ScorpioExec，ScorpioMaker，ScorpioTest。把Scorpio整个文件夹复制到 Unity3d里（如果还不知道Scorpio-CSharp是什么或者是热更新是什么请点这里和这里）。
3.做一个底层。新建2个脚本，ActionManager和ScriptComponent。ActionManager主要是提供一些方法方便调用，而ScriptComponent是为了过渡C# 脚本，或者也可以说是从C#到Scorpio-CSharp的一个接口。而运行一个Scorpio-CSharp脚本需要压入程序集（PushAssembly）和导入类（import_type）
Singleton：方便全局调用
1 //单例模式
2 public abstract class Singleton<T> where T : class, new()
3 {
4 static T msInstance = null;
5 public static T Instance { get { return msInstance ?? (msInstance = new T()); } }
6 }
ActionManager：
1.它可以随时随地运行一个热更新脚本，但是该脚本挂载的ScriptComponent是摄像机的，也就是说this.gameObject获得的是摄像机的，OnTriggerEnter之类的函数也是摄像机。
2.它也可以通过RunScript运行指定物体上的热更新脚本
注意，所有的热更新脚本已通过ActionManager把常用类导入进去了且都放在了Resources文件夹下，通过Resources.Load读取。

ScriptComponent:
1 using UnityEngine;
2 using Scorpio;

4 public class ScriptComponent : MonoBehaviour
5 {
6 public Script script;
7 public ScriptTable scriptTable;
8
9 public void Init(Script source)
10 {
11 script = source;
12 scriptTable = source .GetGlobalTable ( );
13 scriptTable .SetValue ( "transform" , script .CreateUserdata ( this .transform ) );
14 scriptTable .SetValue ( "gameObject" , script .CreateUserdata ( this .gameObject ) );
15 OnStart ( );
16 }
17
18 void OnStart()
19 {
20 Call ( "Awake" );
21 }
22
23 void Start()
24 {
25 Call ( "Start" );
26 }
27
28 void Update()

31 }
32
33 void FixedUpdate()

38 void OnGUI ( )
39 {
40 Call ( "OnGUI" );
41 }
42
43 void OnCollisionEnter ( Collision otherCollider )
44 {
45 Call ( "OnCollisionEnter" , otherCollider );
46 }
47
48 void OnCollisionStay ( Collision otherCollider )
49 {
50 Call ( "OnCollisionStay" , otherCollider );
51 }
52
53 void OnCollisionExit ( Collision otherCollider )
54 {
55 Call ( "OnCollisionExit" , otherCollider );
56 }
57
58 void OnTriggerEnter ( Collider otherCollider )
59 {
60 Call ( "OnTriggerEnter" , otherCollider );
61 }
62
63 void OnTriggerStay ( Collider otherCollider )
64 {
65 Call ( "OnTriggerStay" , otherCollider );
66 }
67
68 void OnTriggerExit ( Collider otherCollider )
69 {
70 Call ( "OnTriggerStay" , otherCollider );
71 }
72
73 public void Call(string func, params object[] args)
74 {
75 if(scriptTable != null && scriptTable.HasValue(func))
76 {
77 ( ( ScriptFunction ) scriptTable .GetValue ( func ) ) .call ( args );
78 }
79 }
80 }
ImportType：
1 //UnityEngine
2 GameObject = import_type("UnityEngine.GameObject")
3 Object = import_type("UnityEngine.Object")
4 Mathf = import_type("UnityEngine.Mathf")
5 PrimitiveType = import_type("UnityEngine.PrimitiveType")
6 Resources = import_type("UnityEngine.Resources")
7 Debug = import_type("UnityEngine.Debug")
8 Transform = import_type("UnityEngine.Transform")
9 Vector2 = import_type("UnityEngine.Vector2")
10 Vector3 = import_type("UnityEngine.Vector3")
11 Vector4 = import_type("UnityEngine.Vector4")
12 Application = import_type("UnityEngine.Application")
13 Time = import_type("UnityEngine.Time")
14 Camera = import_type("UnityEngine.Camera")
15 LineRenderer = import_type("UnityEngine.LineRenderer")
16 Screen = import_type("UnityEngine.Screen")
17 SleepTimeout = import_type("UnityEngine.SleepTimeout")
18 Input = import_type("UnityEngine.Input")
19 SpriteRenderer = import_type("UnityEngine.SpriteRenderer")
20 KeyCode = import_type("UnityEngine.KeyCode")
21 Color = import_type("UnityEngine.Color")
22 Random = import_type("UnityEngine.Random")
23 Quaternion = import_type("UnityEngine.Quaternion")
24 Animator = import_type ("UnityEngine.Animator")
25 Renderer = import_type ("UnityEngine.Renderer")
26 Collision = import_type("UnityEngine.Collision")
27 AudioSource = import_type("UnityEngine.AudioSource")
28 Rigidbody = import_type("UnityEngine.Rigidbody")
29 //System
30 byte = import_type("System.byte")
31 int = import_type("System.Int32")
32 float = import_type("System.Single")
33 double = import_type("System.Double")
34 bool = import_type("System.Boolean")
35 string = import_type("System.string")
36
37 List = import_type("System.Collections.Generic.List`1")
38 ListInt = generic_type(List, int)
39 ListGameObject = generic_type(List, GameObject)
40
41 //Owner class
42 ActionScriptManager = import_type("ActionScriptManager")
43 ScriptComponent = import_type("ScriptComponent")
44 Script = import_type("Scorpio.Script")
4.修改Done_PlayerController成热更新脚本，在Done_GameController脚本的Start函数中加入下面代码，修改类Done_Boundary，加入构造函数。
1 ScriptComponent sc = GameObject.FindGameObjectWithTag("Player").AddComponent<ScriptComponent>();
2 Script s = new Script();
3 sc .Init ( s );
4 ActionScriptManager .Instance .SetScript ( s );
5 ActionScriptManager .Instance .RunScript ( s , "PlayerController" );
Done_PlayerController.txt:
1 var speed = 10;
2 var tilt = 5;
3 var boundary = Done_Boundary(-6, 6, -4, 8);
4 var shot;
5 var shotSpawn;
6 var fireRate = 0.25;
7 var nextFire = 0;
8 function Update ()
9 {
10 shot = Resources.Load("Done_Bolt");
11 shotSpawn = transform.FindChild("Shot Spawn");
12 if (Input.GetButton("Fire1") && Time.time > nextFire)
13 {
14 nextFire = Time.time + fireRate;
15 GameObject.Instantiate(shot, shotSpawn.position, shotSpawn.rotation);
16 gameObject.GetComponent(typeof(AudioSource)).Play ();
17 }
18 }
19 function FixedUpdate()
20 {
21 var moveHorizontal = Input.GetAxis ("Horizontal");
22 var moveVertical = Input.GetAxis ("Vertical");
23 var movement = Vector3 (moveHorizontal, 0.0, moveVertical);
24 gameObject.GetComponent(typeof (Rigidbody)).velocity = Vector3.op_Multiply(movement, speed);
25 gameObject.GetComponent(typeof(Rigidbody)).position = Vector3
26 (
27 Mathf.Clamp (gameObject.GetComponent(typeof(Rigidbody)).position.x, boundary.xMin, boundary.xMax),
28 0.0,
29 Mathf.Clamp (gameObject.GetComponent(typeof(Rigidbody)).position.z, boundary.zMin, boundary.zMax)
30 );
31 gameObject.GetComponent(typeof (Rigidbody)).rotation
32 = Quaternion.Euler(0, 0, gameObject.GetComponent(typeof (Rigidbody)).velocity.x * -tilt);
33 }
今天就先到这里了。。。

注意：
1.假如在热更新脚本里使用系统或者unity的类，需先把程序集压入到Script里面（俩个类在同意程序集只用压一次）， 然后再热更新脚本前头声明该类来自那个程序集（每个类都必须声明）。
如果说是自己写的类直接import_type和scriptTmp .PushAssembly ( GetType ( ) .Assembly );
例如（GameObject和Object在同一程序集里）：
scriptTmp .PushAssembly ( typeof ( Object ) .Assembly );
GameObject = import_type("UnityEngine.GameObject")
Object = import_type("UnityEngine.Object")
2.Scorpio-CSharp脚本类似js脚本，声明全部用var
3.默认数字为double和long，0为long,0.0为double
4.没有new关键字，类初始化可以直接GameObject()，不需要new
5.可以GetComponent(typeof(AudioSource))，不能GetComponent<AudioSource>()
6.没有重写+=,-=,/=,*=操作符，可以通过Vector3.op_Multiply（乘），Vector3.op_Addition（加）实现
7.热更新脚本没有继承mono使用创建和摧毁前得加上GameObject(GameObject.Destroy)
