How do you work with DotNetGenericList?

[hntd187]

Hey Praydog,

Been working a lot with the framework and it all looks great. I'm trying to see the HP of the current enemies around me, but I can't seem to figure out the structure of the EnemyManager in app.ropeway.EnemyManager the enemy list is a DotNetGenericList, but I keep crashing RE2 trying to get some information about the elements. I can iterate over the data, and get their respective types, but it seems like it doesn't like trying to actually do anything with the app.ropeway.EnemyManager.RegisterEnemyInfo it just bombs. I can't find any other mods that work with the generic list and I don't know if you're still working on this project, but have you had any success working with this?

Hey. I haven't really worked on this project in a while, but I'd be glad to help.

I had the same problem when I was trying to port this project to DMC5, but never committed the fix. I've committed the change that should fix this. Let me know if there's anything else you need help with.

Thanks any improvements to the obj explorer is helpful. What I meant was I am developing my own mod https://github.com/hntd187/RE2-Mod-Framework/blob/master/src/Speedrun.cpp and I was trying to find enemy health but actually accessing this seems problematic and crashes a lot.

I get it similar to this

auto enemy_manager = globals.get<RopewayEnemyManager>("app.ropeway.EnemyManager");

but then reading it doesn't work. I was trying to read the enemy_manager->enemyList but reading into the actual list doesn't work. The resharper export marks it as a DotNetGenericList do you have any insight on reading this? Or if you know a better way to get the current enemy info I'm happy to use that instead, thanks a lot for the help

Here's a little example of how to get all the enemies' HP.

    auto enemy_manager = g_framework->getGlobals()->get<RopewayEnemyManager>("app.ropeway.EnemyManager");

    if (enemy_manager == nullptr) {
        return;
    }

    // Be sure to check for null pointers.
    // This is the active enemies list
    auto enemy_controllers = enemy_manager->enemyControllers;

    if (enemy_controllers == nullptr || enemy_controllers->data == nullptr) {
        return;
    }

    // numElements is the total allocated, not the actual number of elements, so there could be empty entries
    for (auto i = 0; i < enemy_controllers->data->numElements; ++i) {
        // app.ropeway.EnemyController
        auto enemy_controller = utility::REArray::getElement<RopewayEnemyController>(enemy_controllers->data, i);

        // Not valid.
        if (enemy_controller == nullptr) {
            break;
        }

        // May not be necessary, if the field is guaranteed to not be corrupted.
        if (!utility::REManagedObject::isManagedObject(enemy_controller)) {
            continue;
        }

        REBehavior* hitpoint_controller = nullptr;

        // Traverse the enemy controller's children to find the hitpoint controller
        for (auto component = enemy_controller->childComponent; component != nullptr && component != enemy_controller; component = component->childComponent) {
            if (utility::REManagedObject::isA(component, "app.ropeway.HitPointController")) {
                hitpoint_controller = (REBehavior*)component;
                break;
            }
        }

        if (hitpoint_controller == nullptr) {
            continue;
        }

        // Get the health
        auto health = utility::REManagedObject::getField<int32_t>(hitpoint_controller, "CurrentHitPoint");

        // Do whatever you wanted to do here.
    }

Interesting, I was doing something very similar to this, lemme try this and get back to you, thanks a lot for the help

Okay that works perfectly, I wonder what I was doing wrong here, but I think I wasn't traversing to the hit point controller correctly so thanks that helps a lot.
