@idk-my-name Time to make a complete client in a client I guess

However, is this for 1.12 forge since IGenericEvent isn't in forge 1.8.9 classloader? I don't know anything about forge modding.

[idk my name]

@czechhek I've been using 1.12 Forge API, but I don't think that it would be that hard to remake register function from 1.8.9 forge (btw i'll do this in 15 min, wait)

[idk my name]

@czechhek 1.8.9 Forge's EventBus is more simple, take a look: https://github.com/MinecraftForge/MinecraftForge/blob/d06e0ad71b8471923cc809dde58251de8299a143/src/main/java/net/minecraftforge/fml/common/eventhandler/EventBus.java#L97

1.8.9 version (?):

function register(eventClass, listener) {
    //we are making reflected event bus to access private fields & methods
    adaptedBus = new Reflector(MinecraftForge.EVENT_BUS);

    //getting an actual mod container (it seems that activeModContainer() returns null in LiquidBounce so we are checking for null & redefining to minecraft mod container)
    activeModContainer = Loader.instance().activeModContainer();
    !activeModContainer && (activeModContainer = Loader.instance().getMinecraftModContainer());

    //https://github.com/MinecraftForge/MinecraftForge/blob/d06e0ad71b8471923cc809dde58251de8299a143/src/main/java/net/minecraftforge/fml/common/eventhandler/EventBus.java#L58
    adaptedBus.listenerOwners.put(listener, activeModContainer);

    ctr = eventClass.getConstructor();
    ctr.setAccessible(true);

    EVENT = ctr.newInstance();

    //don't remove this line because event won't call without it
    asm = new ASMEventHandler(listener, getMethod(listener, "invoke"), activeModContainer);

    //registering a new listener
    EVENT.getListenerList().register(adaptedBus.busID, EventPriority.NORMAL, listener);

    others = adaptedBus.listeners.get(listener);
    if (!others) {
        others = new ArrayList();
        adaptedBus.listeners.put(listener, others);
    }
    others.add(asm)
}
