Hello there!
I would like to share with you guys my library which I’m developing since cocos2d-x v2 (ofc not all the time :D)
I wan’t to give it time to grow up and i needed to test it in real world projects.
I would like to hear you comments 
Thx!
Also I can mention that my company is looking for cocos2d-x developers 
Recent update of syntax (example):
- Store bus
// store it in controller / singleton / std::sharted_ptr whenever you want
Dexode::EventBus bus;
- Define events
namespace Event // optional namespace
{
struct Gold
{
int goldReceived = 0;
};
struct OK {}; // Simple event when user press "OK" button
}
- Subscribe
// ...
bus.listen<Event::Gold>
([](const auto& event) // listen with lambda
{
std::cout << "I received gold: " << event.goldReceived << "!" << std::endl;
});
HudLayer* hudLayer;
// Hud layer will receive info about gold
bus.listen<Event::Gold>(std::bind(&HudLayer::onGoldReceived,hudLayer,std::placeholders::_1));
- Notify
//Inform listeners about event
bus.notify(Event::Gold{12}); // 1 way
bus.notify<Event::Gold>({12}); // 2 way
Event::Gold myGold{12};
bus.notify(myGold); // 3 way
Lambda listener:
struct SampleEvent {};
Dexode::EventBus bus;
//...
int token = bus.listen<SampleEvent>([](const SampleEvent& event) // register listener
{
});
//If we want unlisten exact listener we can use token for it
bus.unlistenAll(token);
Listener is identified by token. Token is returned from EventBus::listen methods.
We can register multiple listeners on one token:
Dexode::EventBus bus;
struct SampleEvent {};
//...
int token = bus.listen<SimpleEvent>([](const auto& event) // register listener
{
});
bus.listen<SimpleEvent>(token, [](const auto& event) // another listener
{
});
bus.unlistenAll(token);//Now those two lambdas will be removed from listeners
If you don’t want to handle manually with token you can use EventCollector class.
It is useful when we want to have multiple listeners in one class. So above example could look like this:
Dexode::EventBus bus;
struct SampleEvent {};
Dexode::EventCollector collector{&bus};
//...
collector.listen<SampleEvent>([](const SampleEvent& event) // register listener
{
});
collector.listen<SampleEvent>([](const SampleEvent& event) // another listener
{
});
collector.unlistenAll();//Now those two lambdas will be removed from listeners
Or as component of class:
class Example
{
public:
Example(const std::shared_ptr<Dexode::EventBus>& bus)
: _collector{bus}
{
_collector.listen<SimpleEvent>(std::bind(&Example::onEvent1, this, std::placeholders::_1));
_collector.listen<OtherEvent>(std::bind(&Example::onEvent2, this, std::placeholders::_1));
}
void onEvent1(const SimpleEvent& event)
{
}
void onEvent2(const OtherEvent& event)
{
}
private:
Dexode::EventCollector _collector;// use RAII
};
//EventCollector sample
std::shared_ptr<Dexode::EventBus> bus;
Example ex{bus};
//...
bus.notify<int>("event1", 2);
