将animator改为animation
最近由于项目需要，要将以前实现ui动画的animator全部改为animation组件。
思路：（1）获取目标路径内的所有object路径，在场景内生成ui预制体，查找并替换所有animator为animation，删除原prefab，由场景内的gameobject在原文件位置生成同名预制体，保存。
（2）由于animator使用的animationclip的legacy属性为false，不能再animation上使用，又由于手动在debug界面上修改此值，运行一次后会还原，故将所有animationclip使用代码复制一份并设置legacy，删除原clip并在原文件位置保存。
以下为代码：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO;
using UnityEditor;
public class Animator2Animation : MonoBehaviour {
// Use this for initialization
void Start () {
Invoke("ChangeClipForAnimation", 3);
}
///
/// 将目录内所有的animationClip复制一份，将其legacy设置为true，保存同名clip并删除旧的animationclip
///
public void ChangeClipForAnimation()
{
print("change Clip start !!!");
//获取所有object的路径
string[] allPath = Directory.GetFiles(Application.dataPath + "/animator2animation", "*", SearchOption.AllDirectories);
//循环遍历每一个路径，单独加载
foreach (string strobjPath in allPath)
{
if (strobjPath.EndsWith(".anim"))
{
//替换路径中的反斜杠为正斜杠
string strTempPath = strobjPath.Replace(@"\", "/");
//截取我们需要的路径
strTempPath = strTempPath.Substring(strTempPath.IndexOf("Assets"));
//根据路径加载资源
Object obj = AssetDatabase.LoadAssetAtPath(@strTempPath, typeof(Object));
AnimationClip clip = obj as AnimationClip;
AnimationClip newclip = new AnimationClip();
newclip.name = clip.name;
newclip.legacy = true;
AnimationClipSettings clipSetting = AnimationUtility.GetAnimationClipSettings(clip);//获取AnimationClipSettings
AnimationUtility.SetAnimationClipSettings(newclip, clipSetting);//设置新clip的AnimationClipSettings
newclip.frameRate = clip.frameRate;//设置新clip的帧率
EditorCurveBinding[] curveBindings = AnimationUtility.GetCurveBindings(clip);//获取clip的curveBinds
for (int i = 0; i < curveBindings.Length; i++)
{
AnimationUtility.SetEditorCurve(newclip, curveBindings[i], AnimationUtility.GetEditorCurve(clip, curveBindings[i]));//设置新clip的curve
}
GameObject.DestroyImmediate(clip, true);
strTempPath = strTempPath.Substring(0, strTempPath.LastIndexOf('/'));
AssetDatabase.CreateAsset(newclip, strTempPath + "/" + newclip.name + ".anim");
}
}
print("change clip over!!!");
}
