如何将基类也注册到lua中？

[ThisisGame]

#include <iostream>

#include <ScriptX/ScriptX.h>

using namespace script;

std::shared_ptr<script::ScriptEngine> createEngine() {
#if !defined(SCRIPTX_BACKEND_WEBASSEMBLY)
    return std::shared_ptr<script::ScriptEngine>{new script::ScriptEngineImpl(),
                                                 script::ScriptEngine::Deleter()};
#else
    return std::shared_ptr<script::ScriptEngine>{script::ScriptEngineImpl::instance(), [](void*) {}};
#endif
}

class Component:public script::ScriptClass{
public:
    using script::ScriptClass::ScriptClass;
    Component(): script::ScriptClass(script::ScriptClass::ConstructFromCpp<Component>{}) {}

    virtual void Awake(){
        std::cout<<"Component Awake"<<std::endl;
    };
};

class Camera:public Component,public script::ScriptClass//warning: direct base 'script::ScriptClass' inaccessible in 'Camera' due to ambiguity [-Winaccessible-base]
{
public:
    using script::ScriptClass::ScriptClass;//error: cannot inherit constructors from indirect base 'script::ScriptClass'
    Camera(): script::ScriptClass(script::ScriptClass::ConstructFromCpp<Camera>{}) {}

    void test_set(int a){
        std::cout<<a<<std::endl;
    }
};

int main() {
    auto engine = createEngine();
    script::EngineScope enter(engine.get());

    // 测试c++继承
    {
        const auto componentDefine =
                script::defineClass<Component>("Component")
                        .nameSpace("UnityEngine")
                        .constructor()
                        .instanceFunction("Awake", &Component::Awake)
                        .build();
        engine->registerNativeClass<Component>(componentDefine);

        const auto cameraDefine =
                script::defineClass<Camera>("Camera")
                        .nameSpace("UnityEngine")
                        .constructor()
                        .instanceFunction("test_set", &Camera::test_set)
                        .instanceFunction("Awake", &Camera::Awake)
                        .build();
        engine->registerNativeClass<Camera>(cameraDefine);
    }

    return 0;
}

提示错误

似乎你对C++不太熟悉，Component继承了ScriptClass，Camera继承了Component然后又继承了ScriptClass。

lua内部要继承的话，可以从纯Lua代码的metatable角度去实现继承，和继承普通的lua类一样

这……，我糊涂了，感谢大佬解答，c++确实用的不多。
测试了不用注册基类。
但是发现另外一个问题，还请大佬看看。

class Component{
public:
    Component(){}

    virtual void Awake(){
        std::cout<<"Component Awake"<<std::endl;
    };

    virtual void Update(){
        std::cout<<"Component Update"<<std::endl;
    };
};

class Camera:public Component,public script::ScriptClass
{
public:
    using script::ScriptClass::ScriptClass;
    Camera():Component(),script::ScriptClass(script::ScriptClass::ConstructFromCpp<Camera>{}) {}
};

int main() {
    auto engine = createEngine();
    script::EngineScope enter(engine.get());

    // 测试c++继承
    const auto cameraDefine =
            script::defineClass<Camera>("Camera")
                    .nameSpace("UnityEngine")
                    .constructor()
                    .build();
    engine->registerNativeClass<Camera>(cameraDefine);

    engine->eval(R"(
        local camera=UnityEngine.Camera()
    )");

    return 0;
}

测试环境：CLion+MinGW。
上面的代码会输出 Component Update，但是没有崩溃报错。

切换到CLion+VisualStudio 2019。
会有下面的崩溃。

建议看看函数注释和详细的项目文档吧

看一下你的这段代码

class Camera:public Component,public script::ScriptClass
{
public:
    using script::ScriptClass::ScriptClass;
    Camera():Component(),script::ScriptClass(script::ScriptClass::ConstructFromCpp<Camera>{}) {}
};

1. script::ScriptClass(script::ScriptClass::ConstructFromCpp<Camera>{})不是这么用的，文档里其实强调的很强烈了。
2. 单测代码里有这个场景 https://github.com/Tencent/ScriptX/blob/main/test/src/NativeTest.cc#L715
