我在使用Unity Unity 2022.1.24f1和WebGL的生产环境中遇到了一个调试问题。当异常发生时,我得到了一个不可读的堆栈跟踪。如下所示:

我无法为生产环境启用调试符号模式,有没有算法可以将此堆栈跟踪转换为真实的的方法名称?
我发现Library\Bee\artifacts\WebGL\il2cppOutput\cpp\Symbols\MethodMap.tsv文件包含我的应用程序中的所有方法名称,但我没有发现这些方法名称/其序列号与stacktrace中的编号之间的任何关系。

slmsl1lt

slmsl1lt1#

tsv包含了c#和c函数之间的关系,这是编译到WASM的第一步,第二步在build目录中创建一个文件. symbols.json(对于Unity 2021和更新版本,在旧版本中它有一个不同的名称)它包含了c和wasm函数之间的关系,但是要得到这个文件,您需要将“发布设置”中的“调试符号”设置为“外部”值。
