So I want to deny all mob spawns, so that i can add in specific mobs to each biome.

I've already tried handling this event.

 

@SubscribeEvent

public void onCheckSpawn(LivingSpawnEvent.CheckSpawn event)

{

event.setResult(Result.DENY);

}

 

but it doesn't work, am i missing something?

i want to avoid despawning if possible and just deny the spawn from occurring in the first place.

 

Not that I know of, you can look at how Minecraft does it with the difficulties.

 

The only way (complex) I can think of right now is EntityJoinWorldEvent. You can check for mobs and cancel the event.

Does any know how the LivingSpawnEvent.CheckEvent actually works, in the code it has this

 

    /**

    * Fires before mob spawn events.

    *

    * Result is significant:

    *    DEFAULT: use vanilla spawn rules

    *    ALLOW:  allow the spawn

    *    DENY:    deny the spawn

    *

    */

 

sounds like what I'm after but it doesn't work, as in mobs continue to spawn like normal, is this a bug, or am i using it wrong?

println confirms that it is being called, but it doesn't deny any spawns.

 

 

How have you been registering it?

 

Show me you main class.

just like this, not sure if that's the correct event bus?

 

@EventHandler

public void init(FMLInitializationEvent event)

{ 

        MinecraftForge.EVENT_BUS.register(new NGUEventHandler());

}

That's exactly the problem, wrong event bus.

The event is an FML event.

 

You should use:

FMLCommonHandler.instance().bus().register(Object obj);

 

#obj = your event handler class.

ok so now i have this in the main class file

 

@EventHandler

public void init(FMLInitializationEvent event)

{ 

    MinecraftForge.EVENT_BUS.register(new NGUEventHandler());

    FMLCommonHandler.instance().bus().register(new NGUFMLHandler());

}

 

and this in a new class file.

 

public class NGUFMLHandler {

 

@SubscribeEvent

public void onLivingSpawnCheckSpawn(LivingSpawnEvent.CheckSpawn event)

{

System.out.println("denied");

event.setResult(Result.DENY);

}

 

problem is it never gets called!

Tell me why the heck you didn't remove:

MinecraftForge.EVENT_BUS.register(new NGUEventHandler());

 

I usually post my events on postInit(FMLPostInitializationEvent event)

because i have other events handled there, but i tried commenting it out anyway and posting the event to postInit, preInit and load, none of which were being called.

 

looks like i'll just have to use the EntityJoinWorldEvent and cancel it when necessary.

I have never done that before.

I usually do seperate event classes if it uses another bus.

Try and seperate them apart.

This is a server side only, MinecraftForge.EVENT_BUS event.

Make sure there is nothing related to client side on your event listener.
