Lua Profiler For Unity


Purpose

Unity + Lua script is now most popular incremental update frameWork for mobile game in China,However, since there haven't been good tool to monitor the cpu and memory usage of lua vm, lots of developers have no idea to optimize their code,so there are many potential risks in lua codes.
this tool is designed to support an easy-to-use profiler for unity that help finding bottleneck and make your game more fast and stable.

Test Demo

use administrator mode to run the link.bat

Use renderings

Deploy and Install

Lua Profiler For Unity supports XLua、SLua、ToLua and also a remote profiler tool so it supports Windows、Android、IOS On-device Profiler.

  • You must open two unity projects,one for game client ,one for editor server
  • Open LuaProfiler folder
  • Copy LuaProfilerClient folder to you game project content,if your C# Lua script is in Plugins folder,Copy LuaProfilerClient to Plugins.This Tool must make sure That code must in the same DLL which has C# lua codes.If you already import Mono.ceil library,delete LuaProfilerClient/Editor/Ceil
  • Use Unity5.6 or newer unity version to create a project, copy LuaProfilerServer to the project content

Datas Descriptions

Name Descriptions
Overview function name
totalLuaMemory The sum of all Lua GCs produced by this function If GC happens then the value will not be very accurate
self The amount of GC produced by the function itself,If the value is negative, the subfunction produces a GC
totalMonoMemory The sum of all Mono GCs produced by this function If GC happens then the value will not be very accurate
self The amount of GC produced by the function itself ,If the value is negative, the subfunction produces a GC
currentTime The time it takes for the function to run in current frame
averageTime Count the average value of the time spent on the function
totalTime All the time consumed by this function
LuaGC Lua GC generated by the current frame
MonoGC Mono GC generated by the current frame
totalCalls The number of runs of this function after the game starts
Calls The number of executions of the current frame of the function

Theory

It use mono.ceil's IL inject feature(also use in XLua),inject the profiler code to game code

Tutors

Config your client

Open windows by "Window->Lua Profiler Window", toggle profiler's feature and configure the server ip address.


Select the kind of code you want profiler,C# code color is green,and lua code color is blue.

Open server

Also open windows by "Window->Lua Profiler Window", then click OpenService,wait for client connects

Charts

  • Toggle LuaChart to open lua memory chart,line color is blue.
  • Toggle MonoChart to open mono memory chart,line color is green.
  • Toggle FpsChart to open fps chart,line color is orange.

Record mode

Click Record button, when game connect to server, toggle StartRecord to start or stop record.

Record button feature


  • drag slider to modify samples
  • click '<' 、 '>' to increase or discrease frames one by one
  • click '<<' 、 '>>' to fast locate the frames control by Capture Lua GC、Capture Mono GC、Frame Count
  • stop record and press left or right arrow keybord to increase or discrease frames one by one

On-device Profiler

Set macro USE_LUA_PROFILER to inject profiler code in you App.If you want to use luac code or luajit bytecode ,use InjectLua.exe in folder tools To inject the lua profiler code.

InjectLua.exe "inpath" "outpath"

Use Case
