Unity3D 导入脚本のAnimation动画切割

• 为了让结构更加清晰，我把这几个需要导表的数据用类封装一下，这个类是一个AnimationClip需要的数据。
• clipST这个类只记录一个AnimationClip的数据，一个模型会有N个AnimationClip组成，所以还要有一个类（modelst)来封装这一堆AnimationClip。并且还要记录这堆AnimationClip是给哪个模型用的。
• 然后用一个List存储所有modelst。
• 最后我们用init（）方法，把美工提供的动作信息这些写入结构即可。
  

具体代码如下：

using UnityEngine;
using System.Collections;
using System.Collections.Generic;//自定义的动作配置表（用来预先配置各动作的动作名、起始帧、结束帧和是否循环。）
public static class AnimationClipConfig
{//是否已经初始化public static bool isInit = false;//模型动作配置表（只记录需要配置模型动作的模型）public static List modelList = new List();public static void init(){if (isInit)return;isInit = true;modelST tempModel = new modelST();//需要配置动作的模型名字tempModel.ModelName = "id_3000";//给该模型配置的动作（动作名、起始帧、结束帧、是否循环）tempModel.clipSTs = new clipST[]{new clipST("stand01" , 0, 60, true),         new clipST("stand02" , 143, 193, true),       new clipST("stand01_to_02" , 61, 100, false),  new clipST("stand02_to_01" , 120, 142, false),new clipST("shouji01" , 101, 119, false), new clipST("run01" , 253, 275, true),           new clipST("jump01" , 606, 626, false),       new clipST("jump01_01" , 627, 645, false),     new clipST("jump02" , 646, 663, false),       new clipST("jump02_01" , 664, 686, false),      new clipST("jump02_atk01" , 687, 714, false), new clipST("jump02_atk02" , 442, 456, false),   new clipST("1atk01" , 275, 285, false),       new clipST("1atk02" , 297, 317, false),         new clipST("1atk03" , 329, 349, false),    new clipST("1atk04_end" , 361, 381, false),  new clipST("1atk01_01" , 286, 296, false),      new clipST("1atk02_01" , 318, 328, false),       new clipST("1atk03_01" , 350, 360, false), new clipST("2atk01" , 382, 392, false),       new clipST("2atk02" , 404, 424, false),         new clipST("2atk03" , 436, 456, false),      new clipST("2atk04_end" , 468, 488, false), new clipST("2atk01_01" , 393, 403, false),      new clipST("2atk02_01" , 425, 435, false),       new clipST("2atk03_01" , 457, 467, false),  new clipST("3atk01" , 489, 499, false),       new clipST("3atk02" , 521, 541, false),         new clipST("3atk03" , 553, 573, false),       new clipST("3atk04_end" , 585, 605, false), new clipST("3atk01_01" , 500, 520, false),      new clipST("3atk02_01" , 542, 552, false),       new clipST("3atk03_01" , 574, 584, false),      new clipST("xl_atk01_01" , 194, 252 , false),      new clipST("xl_atk01_02" , 194, 252, true),new clipST("xl_atk01_03" , 194, 252, false),      new clipST("dead01" , 715, 745, false), };modelList.Add(tempModel);}#region ST//动作配置格式public class clipST{public string name;public int firstFrame;public int lastFrame;public bool isloop;public clipST(string _n,int _f,int _l,bool _i) {name = _n;firstFrame = _f;lastFrame = _l;isloop = _i;}}//模型动作表配置搁置public class modelST{public string ModelName;public clipST[] clipSTs;}#endregion
