游戏开发进行中UE5引擎打不开后续

游戏每次启动都有个问题：

之前我实现了插件里的接口，但是已启动，关于接口这一块的就消失了，有些函数还在但是却是自定义事件，不是接口里的，Class Settings里面也提了

然后我把他改成了新的character class，然后在c++的接口新增一个函数，然后无法编译：

无法编译的报错是  invalid path  ,invliad character之类的，百度之后说是项目里每次更新完要提交，猜测是git没有提交，ue项目是包含git信息的

之后ue像之前那样报错，后来经过摸索，发现可以从工程目录里的SaveGames，中看到Crashes，找到最近时间的这个，能看到日志

这个是插件里的成员需要初始化  改完之后依然无法启动报错变成了

,根据之前的经验我把策略变成了先把Default Spawn Pawn也就是BP_MyCharacter.uasset 拷贝出现，当前目录删除掉，这样子GameMode找不到默认Spawn类，但是可以启动

启动之后把他复制进来就行了
