Integrate with 3rd Lua Library

Standard slua release doesn't contains any 3rd Lua library(like protobuf, lpeg etc), if you want to use this library, can visit this forked repo https://github.com/luzexi/slua, it focus slua on integrate with other 3rd library.

Use SLua without Unity3D

You can use slua without Unity3D dependency, it call slua-standalone. Useful for C# server development. Find it on https://www.nuget.org/packages/slua-standalone , and it's maintained by https://github.com/mr-kelly/slua.

Framework with slua

You can use this framework to start your project.

This repo https://github.com/lwkl/xproject universal loading framework using slua load lua byte code in all platform.

This repo http://linkcloud.github.io/ poker game using slua.

This repo https://github.com/mr-kelly/KSFramework based on slua for hot reloadable asset bundle framework.

This repo https://github.com/lulersoft/ME_SLua based on slua for simple game framework.

This repo https://github.com/yaukeywang/2DPlatformer-SLua demonstrate 2DPlatformer game using slua.

This repo https://github.com/tenvick/hugula demonstrate Tetris game using slua.

Help

See inner demo for help or Document (in chinese).

Important

For running demo sucessful, you should generate lua wrap file by your self:

Click menu, SLua->All->Make generate all wrap file for your version of unity.

Had tested for Unity4.6.1/4.6.2/4.6.3/5.0/5.1/5.2/5.3/5.4/5.5

Main feature

• static code generating, no reflection, no extra gc alloc, very fast
• remote debugger
• full support iOS/iOS64, support il2cpp
• above 90% UnityEngine interface exported ( remove flash, platform dependented interface )
• 100% UnityEngine.UI interface ( require Unity4.6+ )
• support standalone mode in .net framework/mono without Unity3D
• support UnityEvent/UnityAction for event callback via lua function
• support delegate via lua function (include iOS)
• support yield call
• support custom class exported
• support extension method
• export enum as integer
• return array as lua table
• using raw luajit, can be replaced with lua5.3/lua5.1

Usage

copy Assets/Plugins Assets/Slua to your $Project$/Assets folder, you will see Slua menu,

click Unity->Make UnityEngine, regenerate UnityEngine interface for lua

click Unity->Make UI, regenerate UnityEngine.UI interface for lua

click Custom->Make, generate custom class interface for lua

Clear custom, delete all generated custom interface

Slua/LuaObject contain pre-generated file for exported interface.

Precompiled slua library in Plugins only included x86(32bit)/macosx(32bit)/iOS(armv7,armv7s,arm64)/Android(armv7-a) platform using luajit, you should compile other platform/lua5.1/luajit by yourself, see build.txt for help.

Usage at a glance

-- import
import "UnityEngine"

function main()

	-- create gameobject
	local cube = GameObject.CreatePrimitive(UnityEngine.PrimitiveType.Cube)

	-- find gameobject
	local go = GameObject.Find("Canvas/Button")
	
	-- get component by type name
	local btn = go:GetComponent("Button")
	
	-- get out parameter
	local ok,hitinfo = Physics.Raycast(Vector3(0,0,0),Vector3(0,0,1),Slua.out)
	print("Physics Hitinfo",ok,hitinfo)
	
	-- foreach enumeratable object
	for t in Slua.iter(Canvas.transform) do
		print("foreach transorm",t)
	end
	
	-- add event listener
	btn.onClick:AddListener(function()
		local go = GameObject.Find("Canvas/Text")
		local label = go:GetComponent("Text")
		label.text="hello world"
	end)
	
	-- use vector3
	local pos = Vector3(10,10,10)+Vector3(1,1,1)
	cube.transform.position = pos
	
	-- use coroutine
	local c=coroutine.create(function()
		print "coroutine start"

		Yield(WaitForSeconds(2))
		print "coroutine WaitForSeconds 2"

		local www = WWW("http://www.sineysoft.com")
		Yield(www)
		print(#Slua.ToString(www.bytes))
	end)
	coroutine.resume(c)

	-- add delegate
	Deleg.daction = {"+=",self.actionD} --it's ok for iOS
	
	-- remove delegate
	Deleg.daction = {"-=",self.actionD} --it's ok for iOS
	
	-- set delegate
	Deleg.daction = function() print("callback") end --it's ok for iOS
	
	-- remove all
	Deleg.daction = nil
end

Export custom class

add CustomLuaClass attribute to your custom class, waiting for compile completed, click "SLua->Custom->Make", you will get interface file for lua.

[CustomLuaClass]
public class HelloWorld   {

}

Benchmark

compared with ulua/raw mono.

with luajit

unit is secend, run 200k times / test, more smarller more better.
