Unity 代碼生成動畫控制器

　　最近項目中有大量的動畫需要在unity中查看，自己一個個托太麻煩，寫了段代碼自動生成。

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

public class Spader : Editor
{
    // 遞歸的遍歷獲取path下的fbx文件
    static List<string> RecursiveGetFiles(string path)
    {
        var ls = new List<string>();
        var dirs = Directory.GetDirectories(path);
        foreach (var d in dirs)
            ls.AddRange(RecursiveGetFiles(d));

        ls.AddRange(Directory.GetFiles(path, "*.fbx"));
        return ls;
    }

    [MenuItem("Animator/Create Animator Controller")]
    static void CreateController()
    {
        // Creates the controller
        var controller = AnimatorController.CreateAnimatorControllerAtPath("Assets/Model/Motion.controller");

        // Get all anim file
        var path = Application.dataPath + "/Resources/";
        var allFiles = RecursiveGetFiles(path);
        var allClips = new List<AnimationClip>();
        foreach (var f in allFiles)
        {
            var fPath = f.Substring(Application.dataPath.Length);
            var fbx = AssetDatabase.LoadAllAssetsAtPath("Assets" + fPath);
            foreach (var ob in fbx)
            {
                if(ob.GetType() == typeof(AnimationClip))
                    if(! ob.name.StartsWith("__preview"))
                        allClips.Add(ob as AnimationClip);
            }
        }

        allClips.Sort((x, y)=> {
            if (x.name == "Idle01")
                return -1;
            else
                return 0;
        });
        
        // Add parameters
        foreach (var clip in allClips)
            controller.AddParameter(clip.name, AnimatorControllerParameterType.Trigger);

        // Add states and transitions
        var rootStateMachine = controller.layers[0].stateMachine;
        foreach (var clip in allClips)
        {
            var state = rootStateMachine.AddState(clip.name);
            state.motion = clip;

            var transition = rootStateMachine.AddAnyStateTransition(state);
            transition.AddCondition(AnimatorConditionMode.If, 0.0f, clip.name);
            transition.canTransitionToSelf = false;

            if (clip.name == "Idle01")
                transition.canTransitionToSelf = true;
        }
    }
}
