UnityWebGL调研(3) 项目打包

2023-11-16

之前单独打包项目中用到的插件的Demo场景都没有问题，开始尝试打包项目参加，结果有问题。

打包能够成功，但是运行有问题，提示中找不到问题所在。

然后这个是新项目，考虑用Unity2019.2.1f打包看看。

和之前一样，逐个打包插件的Demo，都可以，然后加上整个项目，不行。然后一点一点的减少文件，还是不行，最后发现空的项目也不行。新建了一个全新的项目也不行。

错误是：

查到的解决方法有

1.用Administrator启动unity

--不行

2.修改emscripten.config里面的stack_size，加大

--以及是8192了

3.打包目录放到项目同级文件夹不要放到里面

--同事发现的，他可以，我不行。他的是2019.2.0f

---------------------------------------------------------------------------------

今天出差，在一台新笔记本上安装2019.2.1f，不能打包。正好让我看看一个asm2wasm.exe的文件被360删除了，加到信任中也不会恢复，没找到恢复的选项，重装了unity，结果可以打包了。tmd，居然是这个原因，浪费了我2天时间！

应该是之前在公司安装unity2019时把杀毒软件关了，因为破解程序会被识别为病毒删除掉，然后打包测试，然后什么时候把电脑重启了，那个asm2wasm.exe就被杀毒软件删了，不知道是不是打包过程中删的，没注意到。

unity也不提示一下缺少这个exe，要不是今天看到了，不就永远不知道这个原因吗！

----------------------------------------------
项目打包时的另一个问题，经过排查，发现是wcf自动生成的Reference.cs的问题。

通信部分采用webapi，因为客户端服务端的类要一致，而现有的项目的类已经有很多了，在客户端这边重新整理工作量很大，就直接把wcf的类拿来用。另外，之前发现，webgl时类定位放到dll里面会导致json反序列化失败，得不到数据。而直接把类定位代码放到unity项目中则不会有这个问题，采用的方式时把wcf生成的Refrence.cs拿到项目中的方式。

其实之前2017.3.1时，这样时能打包的。只是打包项目场景后运行时出现了其他问题，而改为2019.2时，这个不能打包了。

但是这个确实挺可疑的。

处理方式：

1.把服务端的类定义代码拷贝到unity中，理论上可行的。但是结果发现命名空间不一致，导致需要修改大量的代码（999+个错误)。

2.处理Refrence.cs，将System.ServiceModel.dll相关的代码去掉。

在我这里其实就是把接口定位代码去掉： ILocationService，ILocationServiceChannel，LocationServiceClient。

最开始时打算把[System.ServiceModel......]注释掉的，后来想到直接把接口定位都注释到就好了，这里我需要的也只有类的定义。

--------------------------------------------

还是Refrence.cs的问题，单独测试没问题，加载正式项目时，发现这个文件被识别为“杂项文件”，也就是说，这个文件不被包含在项目中。

感觉这个using有点奇怪，改到外面去，可以包括在项目中了。

然后再改回原来那样，还是再项目中，不知道怎么回事。

反正这样一个过程。

这个“杂项文件”导致的问题就是，项目中的脚本找不到Refrence.cs里面的类了。

----------------------------------

项目文件基本都放进去，修改好后，能够打包出一个东西了，但是为了能够发现打包后的问题，要打包“”Development Build“”。

结果出现错误：

通过老方法，一个一个打包，发现是插件UniversalMediaPlayer导致的，或者说包括UniversalMediaPlayer的话，会出这个问题，但是不知道其它是否有插件也会导致这个问题。继续看看是UniversalMediaPlayer里面的哪个导致的。

发现直接就是UniversalMediaPlayer.cs导致的，至于是里面的什么代码，估计也就是使用UMP的dll的那部分了。

啊，说起来我这个插件是1.1版本的，它反正不支持Webgl，换成新版本的试试。

---------好吧，结果发现2.0.3也不行，单独一个插件一个项目，打包Development Build也是出问题。

先确认大部分功能的可行性，可以先把UMP插件去掉，并且把相关使用代码注释掉。

结论来看，这样子确实能够打包成功，Development模式。

------------------------------------------------------------------

之前大体的打包问题解决了，项目确实能够打包运行了，接下来修改具体功能问题。

改着，改着，改好了要打包测试，发现又不能打包了。

新建独立项目又能打包，而且Reimport All也不行。

重新创建一个项目，慢慢把东西拷贝进去，结果到最后，可以。

奇怪。

在打包一下两个场景的情况试试。
