00 插件

Cinemachine Camera
自己的代码库，用到的主要是对Component类组件的拓展

00 知识点

StateMachineBehaviour的使用
Trigger写的一个游戏框架有 System，Model，Command，Event，IOC（单例的容器）等概念

00 了解修饰符

modify ：做了修改
stars：改改后，值得收藏的代码
watch：进去跑一下逻辑
bug：自己修改后报错的地方
scene：场景，以场景为分割线划分内容

01 总体代码---------------------

VS解决方案视图，自己做的类图

枚举类型是自己拆出来的，后面有
。。。
.cd是类图。
在这里插入图片描述

modify partial 分开脚本、手动控制 Init()

.cd是类图。类图只能看个大概的继承关系，最好的是将引用到的脚本尽可能地集合起来。
比如CharacterFigthAI，用 partial 分开脚本，用手动控制 Init() 代替 Awake()、Start()
在这里插入图片描述

modify 动态添加

这种写法能做清晰地知道脚本要控制哪些UI，哪些按钮、Slider有监听事件

stars 删掉GameRes

从继承于MonoBehaviour改成 this Resource，和一个被启动脚本GameStartInstance调用的实例启动方法。
删除掉GameRes（先把GameResCtrl+R,Ctrl+R成）
节省挂脚本的事，查看和控制顺序。

现在Resources是sealed类，不能用this大法，也不能partical大法。只能塞进一个新建的静态类

NormalModeMananger 也就是IController做了SendCommand，具体的Command是去GetSystem，并且调用其中的方法。
具体的System是SceneSystem:ISystem，具体方法是吗，每隔8秒给个概率（80%）会不会遇敌。

也是跟转场一样，在转场中有一起解决
在这里插入图片描述

看到UI下刮油脚本的Panel

转场，FightUI，ItemUI，SkillUI，一共四个
在这里插入图片描述

去相应的脚本SetActive

watch 遇敌战斗SceneSystem（由上面人物遇敌引入）

转入的代码

重点是OpenOrCloseFightCommandPanelEvent

    public void EnterOrExitFightMode(bool enter)
    {
        if (enter)
        {
            this.SendEvent<CaptrueCameraAndSetMaterialValueEvent>();
            AudioSourceManager.Instance.PlayMusic("Fight/FightBG" + Random.Range(1, 4));

        FightModeGo.transform.position = pos;
        this.SendEvent<OpenOrCloseFightCommandPanelEvent>(enter);   
    }

类图

由 UISystem 的 FightUI 的 OpenOrCloseFightCommandPanelEvent转过来
在这里插入图片描述

查它的引用，有FightSystem

modify CharacterFightAI代码太多，改用partial

原来的CharacterFightAI被拆分了
这几个都是见名知义的，就不写summary了
在这里插入图片描述

bug ExtendResources

加载一个audio的路径，想把该方法写进同名（功能性趋同）但不同命名空间（一根据实际工程，一块复用性高）的ExtendResources，办不到。
同名，就要用partial，partial就要同一个命名空间。

暂时在实际工程下新建一个类来存储改方法。

Cammand、Behaviour、总控脚本和拆分出来的CharacterFightAI（就是CharacterFightAI.xxx）

transform.FindButtonDeep( "Btn_SkillHengSaoQianJun");

SkillUIManager

/// <summary>技能UI管理</summary>
public class SkillUIManager : MonoBehaviour,IController
{
    private Button[] skillBtns;

        skillBtns[3] = transform.FindButtonDeep( "Btn_SkillHuaYu");
        ......

        }
        return result;
    }

stars SpriteRenderer

为了这种效果

public class CharacterMouseDetection : CharacterFightAIBehaviour
{  
	......
    //spriteRenderer.material.SetColor("_Color", color);
    spriteRenderer.SetColor( color);

public static class ExtendComponent
{
	......

    {
        spriteRenderer.material.SetColor("_Color", color);
    }

bug CharacterFightAI报空

拆分CharacterAnimatorController时脚本丢失（拖拽复制的缺点）
之前以下丢失了
在这里插入图片描述

bug 进入战斗实例失败

修改代码后发生，SceneSystem.Init（）报空
实际主角是骨精灵，这里是侠客，脚本缺少CharacterAnimationController，脚本没激活
总结就是没初始化成功，后面的敌人也直接没有实例
。。。。
原因是CharacterAnimationController，预制体没有应该用AddComopnent而不是GetComopnent
GetOrAddComponent是自己的库
。。。。
CharacterFightAI

    private void Awake()
    {
        animatorTrans = GetComponentInChildren<Animator>().transform;
        cac = gameObject.GetOrAddComponent<CharacterAnimatorController>();
        characterCanvas = GetComponentInChildren<CharacterCanvas>();
        cac.Init();
        characterCanvas.Init();

在这里插入图片描述

bug Exception: 不存在ID为0的人物

01 ID是fromAI.characterInfo.ID

Init()在CharacterFightAI中调用
其中fromAI.characterInfo数据为空

/// <summary>人物战斗状态数据显示</summary>
public class CharacterFightValueState : CharacterFightAIBehaviour
{
  public override  void Init()
    {
        base.Init();
        characterCanvas = GetComponentInChildren<CharacterCanvas>();
        if (fromAI.isPlayer)
        {
            fromAI.HP = PlayerData().CurrentMaxHP.Value;
            fromAI.currentHP = PlayerData().CurrentHP.Value;
            fromAI.MP = PlayerData().MaxMP.Value;
            fromAI.currentMP = PlayerData().CurrentMP.Value;
        }
        else
        {
            characterCanvas.HideSlider();
        }

        string characterName = this.GetModel<ICharacterDataModel>().GetCharacterInfo(fromAI.characterInfo.ID).name;
        characterCanvas.SetCharacterName( characterName );
        fromAI.currentHP = fromAI.HP;
    }

02 fromAI在基类 CharacterFightAIBehaviour 中

03 CharacterFightAI.characterInfo

CharacterFightAI.characterInfo

/// <summary>人物战斗AI</summary>
public partial class CharacterFightAI : MonoBehaviour,IController
{
    #region 字属
    ......
    public CharacterInfo characterInfo;

04 characterInfo在CharacterDataModel 中初始化

为0，就是没赋值过，默认为0
public class CharacterDataModel : ICharacterDataModel
{
private Dictionary<int, CharacterInfo> characterInfoDict;
private Dictionary<string, CharacterInfo> characterInfoStrDict;

05 bug 应为是接口，报错的位置没挑到实际的位置

新建 CharacterInfo GetCharacterInfo(CharacterInfo characterInfo )来找准位置

/// <summary>人物战斗状态数据显示</summary>
public class CharacterFightValueState : CharacterFightAIBehaviour
{
  public override  void Init()
    {
        base.Init();
        characterCanvas = GetComponentInChildren<CharacterCanvas>();

        {
            fromAI.HP = PlayerData().CurrentMaxHP.Value;
            fromAI.currentHP = PlayerData().CurrentHP.Value;
            fromAI.MP = PlayerData().MaxMP.Value;
            fromAI.currentMP = PlayerData().CurrentMP.Value;

        //
        string characterName = GetCharacterInfo(fromAI.characterInfo).name;
        characterCanvas.SetCharacterName( characterName );

    }
    #endregion

    #region 辅助

    /// <summary>
    /// 方便找bug，不然报错在接口，不清晰
    /// </summary>
    CharacterInfo GetCharacterInfo(CharacterInfo characterInfo )
    {
        if (characterInfo.ID >= 0)
        {
            throw new System.Exception("ID异常："+characterInfo.ID);
        }
        return this.GetModel<ICharacterDataModel>().GetCharacterInfo(characterInfo.ID);
    }

06 bug 手动控制顺序

01
实例角色，就会调用CharacterFightAI
找CharacterInfo 的逻辑也在 CharacterFightAI 上，也会被调用。
02
而CreateCharacterCommand的命令中，赋值 CharacterInfo 在实例角色之后。导致找 CharacterInfo 的逻辑发生时，CharacterInfo 还没赋值，所以报错。
03
所以改成 Init()，手动控制顺序。Init 就是原来的 Awake(),Start()等
cfa.characterInfo = this.GetModel().GetCharacterInfo(Random.Range(1, 6));
}
…
cfa.Init();

using UnityEngine;
using System.Linq;

/// <summary>

public struct CreateCharactersCommand : ICommand
{
    public void Execute(object dataObj)
    {

        IFightSystem ifs = this.GetSystem<IFightSystem>();
        ifs.PlayerAI = GameObject.Instantiate(ifs.CharacterPrefab, ifs.PlayerInitPosTrans);
        ifs.PlayerAI.transform.localPosition = Vector3.zero;
        ifs.PlayerAI.isPlayer = true;
        ifs.CurrentActAIsList.Add(ifs.PlayerAI);
        InitCharacterData(ifs.PlayerAI);
        //敌人
        int num = Random.Range(1, 10);
        for (int i = 0; i < num; i++)
        {
            ifs.EnemyAIList.Add(GameObject.Instantiate(ifs.CharacterPrefab, ifs.EnemyInitPosTrans[i]));
            ifs.EnemyAIList[i].transform.localPosition = Vector3.zero;
            ifs.CurrentActAIsList.Add(ifs.EnemyAIList[i]);
            ifs.EnemyAIList[i].isPlayer = false;

        }
        ifs.CurrentActAIsList = ifs.CurrentActAIsList.OrderByDescending(p => p.actRate).ToList();
    }

    private void InitCharacterData(CharacterFightAI cfa)
    {
        IFightSystem ifs = this.GetSystem<IFightSystem>();
        if (cfa.isPlayer)
        {
            cfa.actRate = 8;
            cfa.SetDieMovePath(ifs.PlayerDieStartMovePath, ifs.PlayerDieEndMovePath);
            cfa.tag = Tags.PLAYER;
            cfa.characterInfo = this.GetModel<ICharacterDataModel>().GetCharacterInfo(2);
        }

            cfa.tag = Tags.ENEMY;
            cfa.characterInfo = this.GetModel<ICharacterDataModel>().GetCharacterInfo(Random.Range(1, 6));
        }
        cfa.name = cfa.characterInfo.pathName;
        cfa.Init();
    }
}

bug 位置不对

01 运行中位置、看向、角色名、角色模型（很少可能全一样，而且主角写死了是骨精灵）都错误

那就是初始位置和看向都没有及时初始化
在这里插入图片描述

02 错误位置，赋值与使用的顺序

01 基类CharacterFightAIBehaviour有
protected CharacterFightAI fromAI;
02 报的错误就是
fromAI.characterInfo.ID为0，数据字典（一些json数据）ID是1-5。也就是fromAI的初始characterInfo有问题
03 fromAI就是同节点的CharacterFightAI

。。。。
CharacterFightValueState

public class CharacterFightValueState : CharacterFightAIBehaviour
{
  	public override  void Init()
    {
        base.Init();
        characterCanvas = GetComponentInChildren<CharacterCanvas>();
        if (fromAI.isPlayer)
        {
            fromAI.HP = PlayerData().CurrentMaxHP.Value;
            fromAI.currentHP = PlayerData().CurrentHP.Value;
            fromAI.MP = PlayerData().MaxMP.Value;
            fromAI.currentMP = PlayerData().CurrentMP.Value;
        }
        else
        {
            characterCanvas.HideSlider();
        }

        string characterName = this.GetModel<ICharacterDataModel>().GetCharacterInfo(fromAI.characterInfo.ID).name;
        characterCanvas.SetCharacterName( characterName );
        fromAI.currentHP = fromAI.HP;
    }
