I have a really hard time trying to fix this. I basically generate a structure in the world with a custom IWorldGenerator. Sometimes it happens when the structure is generated, it gets cut off at chunk borders.

I tried to force-load the chunks the structure is being built into, but this doesn't work either.

 

I will be grateful for any hint / advice for solving this.

 

Here's a screenshot of how the structure gets cut off:

Here's the IWorldGenerator class:

And here's the actual class where the structure gen is happening:

I have this exact same problem and still have not found a perfect solution.

 

I was able to ameliorate it somewhat, however, by doing my generation on the final PopulateChunkEvents that post every time: GLOWSTONE for the Nether, and ICE for the overworld. LAKE actually is posted last, but it's not posted for every chunk.

 

If you want, you can see what I did here.

 

It's far from perfect, and in fact some of my secret rooms do still get chopped up by chunk borders; if your structure is less than 16x16 in area, as a last resort you can make sure it only ever generates in the center of a chunk; again, not ideal, but it should work.

 

Let me know if you ever come up with a better solution! This problem has been haunting me for months >.<

I've never noticed an event like this existed... It is actually a better solution, since dungeons themselves get also generated "at population".

I will tinker with it and observe the results, Thanks!

So it seems the events fixed my problem, awesome!

Also I actually found the "true-last" event fired during population: PopulateChunkEvent.Post, but note that this is fired in the EVENT_BUS and not in the TERRAIN_GEN_BUS! I don't know if it's still the case in 1.7, though.

 

So here's my modified code:

WorldGenerator (it's now completely event-driven, IMO it's better than the IWorldProvider):

And this is the Common Proxy, where I basically register the generator:

Thanks again, coolAlias for the tip!
