[1.8] FML event bus says class FMLEvent is not an event class

[jeffryfisher]

In my FML event handler class, I subscribe to an event:

  @SubscribeEvent
  public void onMissing(FMLMissingMappingsEvent e)

 

In my mod's postInit, I try to register the event handler class with FML:

  public void postInit(FMLPostInitializationEvent e) {
    super.postInit (e);
    classEventBusSubs eb = new classEventBusSubs ();
    classCommonBusSubs cb = new classCommonBusSubs ();

    MinecraftForge.EVENT_BUS.register (eb);             // All of my "listeners" are in class...EventSubs,
    FMLCommonHandler.instance ().bus ().register (cb);  // So register it on every bus until events are triggered
  }

 

But FML rejects its own event as an event:

[18:44:45] [Client thread/ERROR] [FML]: The following problems were captured during this phase

[18:44:45] [Client thread/ERROR] [FML]: Caught exception from jrfmoonsensor

java.lang.IllegalArgumentException: Method public void jrfmoonsensor.classCommonBusSubs.onMissing(net.minecraftforge.fml.common.event.FMLMissingMappingsEvent) has @SubscribeEvent annotation, but takes a argument that is not an Event class net.minecraftforge.fml.common.event.FMLMissingMappingsEvent

How can it not be an event class??? It's an extension of class FMLEvent! What part of "event" is not being communicated here?

I am still learning but I have never heard of onMissing() method for 1.8 in the API, maybe it has been depreciated? what are you trying to do?

There are two types of events in Forge:

• Events that extend

  FMLEvent

  and are handled by a method with the

  @Mod.EventHandler

  annotation in your

  @Mod

  class (e.g.

  FMLPreInitializationEvent

  ,

  FMLMissingMappingsEvent

  )
  

• Events that extend

  Event

  and are handled by a method with the

  @SubscribeEvent

  annotation in a class registered on the appropriate event bus (e.g.

  BlockEvent.HarvestDropsEvent

  ,

  PlayerEvent.ItemSmeltedEvent

  )
  

 

You're trying to handle an

FMLEvent

like it's an

Event

.

Aha... Coincidence (or confusion?) in naming. I guess I should move the handler to my main mod class (and change the annotation).

 

@statphantom: "onMissing" was just my own choice of method name (I had to call it something).
