Unity Xlua 之 Lua调用C#(四)

一.Lua和系统类，系统委托调用

publicstaticclassLesson10{[CSharpCallLua]privatestatic List<Type> allCSharpCallLuaList =newList<Type>(){typeof(UnityAction<float>)};[LuaCallCSharp]privatestatic List<Type> allLuaCallCSharpList =newList<Type>(){typeof(GameObject),typeof(Rigidbody),};}

复制代码

GameObject = CS.UnityEngine.GameObject
local sliderObj = GameObject.Find("Slider")local sliderComponent = sliderObj:GetComponent(typeof(CS.UnityEngine.UI.Slider))
sliderComponent.onValueChanged:AddListener(function(f)print(f)end)

复制代码

二.Lua调用携程

util =require("xlua.util")
GameObject = CS.UnityEngine.GameObject
WaitForSeconds = CS.UnityEngine.WaitForSeconds
local go =GameObject("Coroutine")local mono = go:AddComponent(typeof(CS.TestMono))
func =function()local a =0whiletruedoprint(a)
a = a +1
coroutine.yield(WaitForSeconds(0.5))if a >=10then
mono:StopCoroutine(b)endendend
b = mono:StartCoroutine(util.cs_generator(func))

复制代码

三.Lua调用泛型方法

publicclassLesson12{publicclassTestFather{}publicclassTestChild:TestFather, ITest
{}publicinterfaceITest{}publicvoidTestFun1<T>(T t1,T t2)where T : TestFather
{
Debug.Log("有参有约束");}publicvoidTestFun2<T>(T t1){
Debug.Log("有参无约束");}publicvoidTestFun3<T>()where T : TestFather
{
Debug.Log("无参有约束");}publicvoidTestFun4<T>(T t1)where T : ITest
{
Debug.Log("有参有接口约束");}}

复制代码

Lesson12 = CS.Lesson12
TestFather = Lesson12.TestFather
TestChild = Lesson12.TestChild
local l12 =Lesson12()local testFather =TestFather()local testChild =TestChild()
l12:TestFun1(testFather,testChild)
l12:TestFun1(testChild,testFather)--l12:TestFun2(testFather)--l12:TestFun2(testChild)local testFun2 = xlua.get_generic_method(CS.Lesson12,"TestFun2")local testFun2_R =testFun2(CS.System.Int32)testFun2_R(l12,123)local testFun3 = xlua.get_generic_method(CS.Lesson12,"TestFun3")local testFun3_R =testFun3(TestFather)testFun3_R(l12)local testFun4 = xlua.get_generic_method(CS.Lesson12,"TestFun4")local testFun4_R =testFun4(TestChild)testFun4_R(l12,testChild)

复制代码

print("*********Lua调用C# 泛型函数相关知识点***********")local obj = CS.Lesson12()local child = CS.Lesson12.TestChild()local father = CS.Lesson12.TestFather()--支持有约束有参数的泛型函数
obj:TestFun1(child, father)
obj:TestFun1(father, child)--lua中不支持没有约束的泛型函数--obj:TestFun2(child)--lua中不支持有约束但是没有参数的泛型函数--obj:TestFun3()--lua中不支持非class的约束--obj:TestFun4(child)--有一定的使用限制--Mono打包这种方式支持使用--il2cpp打包如果泛型参数是引用类型才可以使用--il2cpp打包如果泛型参数是值类型，除非C#那边已经调用过了同类型的泛型参数 lua中才能够被使用--补充知识让上面不支持使用的泛型函数变得能用--得到通用函数 --设置泛型类型再使用--xlua.get_generic_method(类, "函数名")local testFun2 = xlua.get_generic_method(CS.Lesson12,"TestFun2")local testFun2_R =testFun2(CS.System.Int32)--调用--成员方法第一个参数传调用函数的对象--静态方法不用传testFun2_R(obj,1)
