SLua

Fastest lua binding via static code generation for Unity3D or mono

Changes compared to pangweiwei's version

The changes are mostly around readability, classes, variables, and functions now maintain more accurate and descriptive names. There are also a few small functionality changes that improve how the system is used.

This release also trims away some features that aren't specifically useful for Project Porcupine such as Android/IOS (and others) support, along with the removal of standalone functionality.

Main features

static code generation, 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 and Assets/Slua to your $Project$/Assets folder and let it compile
Click Slua/Unity/Make UnityEngine to regenerate the UnityEngine interface for lua
Click Slua/Unity/Make UI to regenerate the UnityEngine.UI interface for lua
Click Slua/Custom/Make to generate custom class interfaces for lua

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 the CustomLuaClass attribute to your custom class, then click SLua/Custom/Make and you will get interface file for lua.

[CustomLuaClass]
public class HelloWorld   {
    ...
