[1.12.2] How to detect feature-gen

[DoctorLOGiQ]

Hey guys. So I have a query, which doesn't come without much code-digging prior to asking.

I'm looking for the best way to have my mod detect when an end gateway is spawned.

I have tried listening for the event

net.minecraftforge.event.ForgeEventFactory.onChunkPopulate(false, this, this.world, this.rand, x, z, false);

which is called right after

(new WorldGenEndGateway()).generate(this.world, this.rand, blockpos1);

in Vanilla's ChunkGeneratorEnd script... but my mod isn't detecting this event. I am using

@SubscribeEvent
public static void onChunkPopulate(PopulateChunkEvent.Post event)

to listen for the event, and I have tried annotating the class with

@Mod.EventBusSubscriber

and registering it with

MinecraftForge.EVENT_BUS.register(...)

but to no avail. Am I doing something wrong? How can I detect when the gateways are spawned, preferably with access to the generation code?

 

Many thanks.

Sure. This is the function. Upon testing, nothing happens, the System.out.println() doesn't even print. I have tested this by killing the Dragon. Each time a new end gateway is spawned, but nothing shows up in the console (and yes, I know Systmem.out.println() isn't the proper way to log, it's only temporary, and works with IDEA).

 

Function:

@SubscribeEvent
public static void onChunkPopulate(PopulateChunkEvent.Post event)
{
   System.out.println("End chunk population event");
   
   if (!event.getWorld().isRemote && event.getGen() instanceof ChunkGeneratorEnd)
   {
      World world = event.getWorld();
      ChunkGeneratorEnd generator = (ChunkGeneratorEnd) event.getGen();
      int chunkX = event.getChunkX(), chunkZ = event.getChunkZ();
      
      for (int x = 0; x < 16; x++)
      {
         for (int y = 8; y < 128; y++)
         {
            for (int z = 0; z < 16; z++)
            {
               if (world.getChunkFromChunkCoords(chunkX, chunkZ).getBlockState(new BlockPos(x, y, z)).getBlock() == Blocks.END_GATEWAY)
               {
                  System.out.println("Located gateway! Chunk X: " + chunkX + ", Chunk Z: " + chunkZ + ", Block X: " + x + ", Block Y: " + y + ", Block Z: " + z);
               }
            }
         }
      }
   }
}

 

Registration (during FMLInitializationEvent?

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

You shouldn't register the class to the event bus if you're already using the annotation and static method. Alternatively you should not make method static. I think your event handler registration isn't right.
