Unity-odin-npbehave结合烟雨大佬的示例-续

本篇主要记录如何使用从ODIN导出的数据给Npbehave使用
注：烟雨大佬的MOBA Demo 是基于ET引擎的

开始

准备工作：1.下载好烟雨大佬的源码即可，也可以自行导入ODIN，自行导入NPBEHAVE

1.上文说到已经成功从ODIN可视化编辑器导出各种NP_NodeDataBase，所以我们需要加载导出数据，然后进行反序列化成我们想要的类实例。由于序列化使用的Mongo的BSON库，然后很多子类父类都需要导出，所以要将所有子类进行注册。

public Dictionary<long, NP_DataSupportor> NpRuntimeTreesDatas = new Dictionary<long, NP_DataSupportor>();

        public void Awake()
        {
            Type[] types = typeof (NodeType).Assembly.GetTypes();
            foreach (Type type in types)
            {
                if (!type.IsSubclassOf(typeof (NP_NodeDataBase)) && !type.IsSubclassOf(typeof (NP_ClassForStoreAction)) &&
                    !type.IsSubclassOf(typeof (SkillBaseNodeData)) && !type.IsSubclassOf(typeof (BuffDataBase)) &&
                    !type.IsSubclassOf(typeof (ListenBuffEventBase)))
                {
                    continue;
                }

                BsonClassMap.LookupClassMap(type);
            }

同时，将导出的文件进行反序列化生成我们需要得行为树节点数据：

DirectoryInfo directory = new DirectoryInfo(NPDataPath);
            FileInfo[] fileInfos = directory.GetFiles();

            foreach (var VARIABLE in fileInfos)
            {
                byte[] mfile = File.ReadAllBytes(VARIABLE.FullName);

                if (mfile.Length == 0) Log.Info("没有读取到文件");

                try
                {
                    NP_DataSupportor MnNpDataSupportor = BsonSerializer.Deserialize<NP_DataSupportor>(mfile);

                    Log.Info($"反序列化行为树:{VARIABLE.FullName}完成");

                    NpRuntimeTreesDatas.Add(MnNpDataSupportor.RootId, MnNpDataSupportor);
                }
                catch (Exception e)
                {
                    Console.WriteLine(e);
                    throw;
                }
            }

2.上面将所有行为树及其节点数据都准备好了，接下来就要用这些行为树节点数据，与NPBehave内的各种节点对应起来，生成真正的NPBehave节点。于是在NP_RuntimeTreeFactory类创建一个NPBehave树实例时，调用节点数据类的不同方法，生成对应的类，并将节点之间的关系通过linkedID进行连接。

NP_DataSupportor npDataSupportor = Game.Scene.GetComponent<NP_TreeDataRepository>().GetNP_TreeData_DeepCopy(NPDataId);

            long theRuntimeTreeID = IdGenerater.GenerateId();
            
            //Log.Info($"运行时id为{theRuntimeTreeID}");
            foreach (var VARIABLE in npDataSupportor.mNP_DataSupportorDic)
            {
                switch (VARIABLE.Value.NodeType)
                {
                    case NodeType.Task:
                        VARIABLE.Value.CreateTask(unit.Id, theRuntimeTreeID);
                        break;
                    case NodeType.Decorator:
                        VARIABLE.Value.CreateDecoratorNode(unit.Id, theRuntimeTreeID,
                            npDataSupportor.mNP_DataSupportorDic[VARIABLE.Value.linkedID[0]].NP_GetNode());
                        break;
                    case NodeType.Composite:
                        List<Node> temp = new List<Node>();
                        foreach (var VARIABLE1 in VARIABLE.Value.linkedID)
                        {
                            temp.Add(npDataSupportor.mNP_DataSupportorDic[VARIABLE1].NP_GetNode());
                        }

                        VARIABLE.Value.CreateComposite(temp.ToArray());
                        break;
                }
            }

3.创建NP_RuntimeTree，填入所有相关行为树数据

 public Root m_NPRuntimeTreeRootNode;

        /// <summary>
        /// 所归属的数据块
        /// </summary>
        public NP_DataSupportor m_BelongNP_DataSupportor;

        public void Awake(Root mRoot,NP_DataSupportor m_BelongNP_DataSupportor)
        {
            this.m_NPRuntimeTreeRootNode = mRoot;
            this.m_BelongNP_DataSupportor = m_BelongNP_DataSupportor;
        }

4.将生成好的行为树加入到行为树管理类中，同时把行为树数放入黑板中

            NP_RuntimeTree tempTree = ComponentFactory.CreateWithId<NP_RuntimeTree, Root, NP_DataSupportor>(theRuntimeTreeID,
                (Root) npDataSupportor.mNP_DataSupportorDic[npDataSupportor.RootId].NP_GetNode(), npDataSupportor);
            
            unit.GetComponent<NP_RuntimeTreeManager>().AddTree(tempTree.Id, npDataSupportor.RootId, tempTree);
            //把提前缓存的数据注入黑板
            unit.GetComponent<NP_InitCacheComponent>().AddCacheDatas2RuntimeTree(tempTree);

自此行为树已经建立好，将root节点start,整个行为树就托管给NPBehave开始跑了
