I'm also experiencing this problem, how did you solve it?

yunli97 commented 2 months ago

imageSo that's the problem here. Here's the modification.

tomasky commented 2 months ago

this Code is not working now no errors report and game exit ! this line cause:

    auto gameObject = BNM::Class("UnityEngine", "GameObject").CreateNewObjectParameters();

:

struct MyClass : public BNM::UnityEngine::MonoBehaviour {
    BNM_CustomClass(MyClass, BNM::CompileTimeClassBuilder("","MyClass").Build(), BNM::CompileTimeClassBuilder("UnityEngine","MonoBehaviour").Build(), {});

    void Update() {
        LOGI("Call Update");
    }

    BNM_CustomMethod(Update, false, BNM::GetType<void>(), "Update");
};

BNM::Method<void*> addComponent;
BNM::Method<void> dontDestroyOnLoad;

void *AttachComponent() {
    auto gameObject = BNM::Class("UnityEngine", "GameObject").CreateNewObjectParameters();
    addComponent[gameObject](MyClass::BNMCustomClass.type);
    dontDestroyOnLoad(gameObject);
    return gameObject;
}

void OnLoad() {
    addComponent = BNM::Class("UnityEngine", "GameObject").GetMethod("AddComponent", {"componentType"});
    dontDestroyOnLoad = BNM::Class("UnityEngine", "Object").GetMethod("DontDestroyOnLoad");

    auto r = AttachComponent();
}

@solomode0001 @yunli97 can you test the BNM lastest version with the example? ,
