一、原理

通过配置表格,自动按设置起始帧和结束帧切割动画,

二、使用步骤

1.配置动画数据

?主要是一个fbx模型名字,用它来区分是那个fbx模型来切割动画的,动画名称:切割后的分段动画的名字,后面也可以填加是否循环,那些数据.

表咋填无所谓,只要在unity能读出来就行.

2.代码

using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEngine;

public class FbxSettingTool : EditorWindow
{
    static FbxSettingTool window;
    [@MenuItem("资源管理/切割动画")]
    private static void Init()
    {
        Rect wr = new Rect(0 , 0 , 400 , 400);
        window = (FbxSettingTool)EditorWindow.GetWindowWithRect(typeof(FbxSettingTool) , wr , false , "动画切割");
        window.Show();
    }
    private void OnGUI()
    {
        if (GUILayout.Button("切割动画设置"))
        {
            //通过Asset点击fbx模型,来读取资源
            Object[] importerObj = Selection.GetFiltered(typeof(Object) , SelectionMode.Assets);

            for (int j = 0; j < importerObj.Length; j++)
            {
                string name = importerObj[j].name;
                string path = AssetDatabase.GetAssetPath(importerObj[j]);
                ModelImporter import = AssetImporter.GetAtPath(path) as ModelImporter;
                //填的动画切割json数据
                List<donghuaJsonCfg> Cfg = donghuaJsonCfgHelper.instance.getJsonCfg(name);

                ArrayList clipsList = new ArrayList();
                for (int i = 0; i < Cfg.Count; i++)
                {
                    //创建分段动画
                    ModelImporterClipAnimation clipAnimation = new ModelImporterClipAnimation();
                    clipAnimation.name = Cfg[i]._name;
                    clipAnimation.firstFrame = Cfg[i].firstFrame;
                    clipAnimation.lastFrame = Cfg[i].lastFrame;
                    clipAnimation.loopPose = false;
                    clipsList.Add(clipAnimation);
                }

                import.clipAnimations = (ModelImporterClipAnimation[])clipsList.ToArray(typeof(ModelImporterClipAnimation));
                import.SaveAndReimport();
                //重新导入
                AssetDatabase.ImportAsset(path);
            }
            AssetDatabase.Refresh();
        }
    }
}
