Top-down-Rpg-Start-kit插件的使用与二次开发

这几天都在说仙剑Demo，为啥突然讲Top-down-Rpg-Start-kit，因为Top-down-Rpg-Start-kit是个非常完整的动作游戏插件，根据其完整文档可以快速开发单机的rpg游戏，我们做的Demo是回合制的，但这个插件的交易系统，状态机，背包系统，小地图系统做的非常好，我们的demo后面的几个系统都使用了Top-down-Rpg-Start-kit的插件源码，利用别人的成熟代码，来完善自己的游戏快速开发，这是我多年的一个开发习惯，废话不说，我们开始，不过开篇可能有些奇怪，因为这个文档我是去年12月份写的，当时是在学习Top-down-Rpg-Start-kit的插件并且整合游戏的任务系统，但后来发现Top-down-Rpg-Start-kit1.2自己加入了任务系统，并且我的实验项目也基本完成所以停了下来，后来开发仙剑的Demo，所以这个文档上面的源码与Top-down-Rpg-Start-kit1.0的源码有很多地方不太一样，不过具体修改的源码我会帖出来，并且写详细的中文注释。我们开始

这一篇的篇幅都是在讲我整喝一个任务系统到这个插件的全过程，因为直接看估计很难看得懂，所以后面我会提供完整的整合任务系统的工程文件，所以到时候再看把，建议大家跳过这一篇，直接看下一篇，等到我提供的工程文件放出来，大家在回来看，否则估计会有很多小伙伴骂我。这个任务系统需要的源码包下载地址密码wjd3，这个包复制进下载的Top-down-Rpg-Start-kit1.0，然后按照最后Hierarchy设置，完整的工程文件因为太大，所以以后有时间放上来。

先上一张插件的logo，新建建立新文件夹，存放修改后的模型元件，代码，资源

建立人物模型组件

1.添加模型（模型要包括动作）到Hierarchy窗口

2．添加角色控制脚本到模型上

3.把人物模型层layer和标签tag改为player

任务系统开发

playerBase.cs修改

     if(globalPrefabs== null){//globalPrefabs=GameObject.FindGameObjectWithTag("GameMaster").GetComponent<GlobalPrefabs>();           }OptionsMenuGUI.cs      //gameSettings=GameObject.FindGameObjectWithTag("GameMaster").GetComponent<GameSettings>();MyGUI.cs      //DisplayPlayerVitalsAndExp(); 

制作一个用于测试的敌人修改中的预制件

注意上面的PlayerNew.cs是我们后加的，源码

运行后的效果

EnemyController.cs中添加

monsterDeadAI中的nameOfMobToSend暂时测试直接写入，后面会改为通用。

杀怪任务修改完毕。。。。。。。。。。。。。。。。。。。。

在EnemyController中添加    privateMonsterAI Monsterai;

在void Start () {}中添加 Monsterai=this.GetComponent<MonsterAI>();

void MonsterDeadAI(){}中修改代码为

string nameOfMobToSend=Monsterai.NameOfMob;

Messenger<string>.Broadcast("MonsterKilled",nameOfMobToSend);

注释掉void Update (){}中的

//         floatcurHealth = GetComponent<Health>().CurrentHealth;

//        

//         if(curHealth<= 0 ){

//              MonsterHealth= 0;

//              isDead= true;

//         }

//  

修改PlayerBase中LevelUpAnimation方法，确保只有一种升级

看看player.QuestsInProgress[i].nameOfMobThatDropsItem这个东东的值是什么，

一口气贴了这么多东西，其实这是我一周时间写的代码和调试信息，而且用到的类也是一个成熟的任务系统，我只是做了整合，

虽然贴出了代码，但说实话，就这么看，估计没人看得懂，而且任务系统还包括一段存储的部分，所以我建议这一篇大家先跳过吧，过段时间我整理一下代码，把整个工程文件发出来，否则这篇真的没法看了。建议大家跳过直接看下一篇。

注意要看上面提供了需要的代码包和任务Npc预制件。
