C++怎么与Lua进行交互_C++使用sol2或luabind库嵌入Lua脚本

#include <sol/sol.hpp><br>
#include <iostream>
<p>int main() {
sol::state lua;
lua.open_libraries(); // 打开标准库</p><pre class='brush:php;toolbar:false;'>// 绑定C++函数
lua["say_hello"] = []() {
    std::cout << "Hello from C++!\n";
};

// 定义变量
lua["value"] = 42;

// 执行Lua代码
lua.script(R"(
    print("Running Lua script")
    say_hello()
    print("Value is:", value)
)");

return 0;

struct MyClass {
    int x = 100;
<pre class='brush:php;toolbar:false;'>void set(int v) { x = v; }
int get() const { return x; }

#include <luabind/luabind.hpp>
<p>void greet() {
std::cout << "Hello from C++ via luabind\n";
}</p><p>int main() {
lua_State* L = luaL_newstate();
luaL_openlibs(L);</p><pre class='brush:php;toolbar:false;'>using namespace luabind;
open(L);

module(L) [
    def("greet", &greet),
    class_<MyClass>("MyClass")
        .def(constructor<>())
        .def("get", &MyClass::get)
        .def("set", &MyClass::set)
];

luaL_dostring(L, R"(
    greet()
    obj = MyClass()
    obj:set(99)
    print(obj:get())
)");

lua_close(L);
return 0;

find_package(Lua REQUIRED)
include_directories(${LUA_INCLUDE_DIR})
<p>add_executable(main main.cpp)
target_link_libraries(main ${LUA_LIBRARY})</p>
