this is my c++ code:

class Base {
public:
    Base() {
        _refCount = 1;
        cout << "Base Create" << endl;
    }

    void addRef() {
        _refCount++;
    }

    void release() {
        _refCount--;
        if (_refCount == 0) {
            delete this;
        }
    }

    void reciever(asIScriptObject *obj) {
        cout << "???" << endl;
        man = obj;
    }

    void active() {
        cout << "??Active" << endl;
        cout << (man == 0) << endl;
        cout << "??Active" << endl;
    }

private:
    int _refCount;
    asIScriptObject *man;
};

Base *Base_Factory() {
    return new Base();
}
......
//---------------------------------------------------------
    scriptEngine->RegisterObjectType("Base", 0, asOBJ_REF);
    scriptEngine->RegisterObjectBehaviour("Base",asBEHAVE_FACTORY, "Base@ f()", asFUNCTION(Base_Factory), asCALL_CDECL);
    scriptEngine->RegisterObjectBehaviour("Base", asBEHAVE_ADDREF, "void f()", asMETHOD(Base, addRef), asCALL_THISCALL);
    scriptEngine->RegisterObjectBehaviour("Base", asBEHAVE_RELEASE, "void f()", asMETHOD(Base, release), asCALL_THISCALL);

    //---------------------------------------------------------
    CScriptBuilder builder;
    r = builder.StartNewModule(scriptEngine, "MyModule");

    int isOK = builder.AddSectionFromFile("init.as");
    asIObjectType *type = scriptEngine->GetObjectTypeByName("Human");
    cout << "type == " << (type == 0) << endl;

    //r = builder.AddSectionFromFile("test.as");

    r = builder.BuildModule();
  
    scriptEngine->RegisterObjectMethod("Base", "void reciever(Human @in)", asMETHOD(Base, reciever), asCALL_THISCALL);
    scriptEngine->RegisterObjectMethod("Base", "void active()", asMETHOD(Base, active), asCALL_THISCALL);
........

and in my init.as script code:

class Human {
	Human(){}
}

but it is still report a error:

Failed in call to function 'RegisterObjectMethod' with 'Base' and 'void reciever(Human @in)' (code: -10)

why ? may it must to reciever a interface nor a script class?

thanks

but there are something like this in the angelScript mannual:

Of course, since the class is declared in the script it isn't possible to know the type before the script is compiled.

but I can't work it successfully

is this because of angelScript does not support reciever a script class thich declared in the as script file?

well thanks

but is this means before we register the reciever function

we can add a new section from file A or memory(string)

so that engine can pass the script code and know the script class declared in file A

and when we register the reciever function the engine had know the script class type

I have try this but it not work

it's so strange>>>right?

thanks

I have learned a lot
