unity2d导入psb文件注意事项

一、前言

导入psb多个图层是方便制作2d骨骼动画

二、设置psb文件锚点

导入psb文件的时候默认的锚点一般都不是我们想要的位置，人物朝左、朝右旋转的时候会出现人物移动很多位置，可以手动设置锚点到我们需要的位置。

三、unity导入psb文件报错

今天开始我的unity导入psb文件就一直报这个错，之前都没问题，重新unity和重启电脑都没用
吐槽

很难在百度找到答案？所以大家是怎样找答案的？求指导。。。

3.2 解决办法

在你的unity项目的任意一个位置创建一个名为的 C# 脚本FixPSDImporter并将其粘贴到其中并修复！

public static class FixPSDImporter
    {
        [UnityEditor.InitializeOnLoadMethod]
        public static void ResetPSDImporterFoldout()
        {
            UnityEditor.EditorPrefs.DeleteKey("PSDImporterEditor.m_PlatformSettingsFoldout");
        }
    }

3.3 后续

嗯，我发现在一个项目创建了这个文件，其他的项目也没报错了，很完美。
