xlua-C#代码访问lua的变量和函数
C#代码如何访问lua代码中数据呢？主要基本数据类型、table以及function函数等。lua代码脚本如下
--Lua全局变量
--[[基本数据类型]]--
Num = 100;
Name = 'Hello';
IsOk = true;
--[]--
example_table={
id = 'W',
age = 10,
sex = 0,
1,--多余变量1
2,--多余变量2
setSex = function(self,sexValue)
sex = sexValue;
end,
getSex = function()
return sex;
end
}
example_table2={
id = 102,
num = 25,
vip = 3
}
example_table3 = {
1,
2,
3
}
--[[函数function]]--
function Method1()
print('=====lua method1=====');
end
function Method2(a,b)
print('=====lua method2=====');
c = a+b;
a=a+2;
b=3;
return c,a,b;
end
function Method3()
print('=====lua method3=====');
return Method1;
end
