gregweng
- After consulting gfx team, now there is a clear concept about how to output TraceLogger data to frontend via WebSocket.
- Done to know how devs log things in JS engine with Tracelogger. Most of them use AutoTraceLog to log method start and end.
- Read through how tracelogger log out...a simple fwrite. I suspect this will make some performance if it really write to file directly and in the synchronous way
- Studying LayerScopeWebSocketManager to see how output log to WebSocket in our engine
