Thank you GreyGhost, this is most helpful! Now I also understand block directions (I found some examples where integers were just hardcoded and wondered what meant what). Thank you!

So this problem persists and I really am extremely puzzled. Here's some code I have @SubscribeEvent public void eventChunkLoad(ChunkEvent.Load event) { Chunk chunk = event.getChunk(); if (chunk == null) { sink.debug("Chunk is null"); return; } if (!chunk.isChunkLoaded) { sink.debug("Chunk " + chunk.xPosition + " / " + chunk.zPosition + " is not loaded (" + chunk.worldObj.getChunkProvider().getLoadedChunkCount() + " loaded chunks)"); return; } And my log shows this: DEBUG: WorldLoad 0 DEBUG: Chunk 12 / 13 is not loaded (1 loaded chunks) DEBUG: Chunk 7 / 16 is not loaded (2 loaded chunks) DEBUG: Chunk 7 / 15 is not loaded (3 loaded chunks) DEBUG: Chunk 7 / 14 is not loaded (4 loaded chunks) DEBUG: Chunk 7 / 13 is not loaded (5 loaded chunks) DEBUG: Chunk 7 / 12 is not loaded (6 loaded chunks) DEBUG: Chunk 7 / 11 is not loaded (7 loaded chunks) DEBUG: Chunk 7 / 10 is not loaded (8 loaded chunks) DEBUG: Chunk 7 / 9 is not loaded (9 loaded chunks) DEBUG: Chunk 7 / 8 is not loaded (10 loaded chunks) DEBUG: Chunk 6 / 16 is not loaded (11 loaded chunks) DEBUG: Chunk 6 / 15 is not loaded (12 loaded chunks) DEBUG: Chunk 6 / 14 is not loaded (13 loaded chunks) DEBUG: Chunk 6 / 13 is not loaded (14 loaded chunks) So apparently the events fire whenever a chunk is loaded, but within that event I cannot access the chunk data (not loaded). The chunk provider however seems to think that all these chunks are loaded (and it increases nicely the loaded chunk count). Does anyone have an idea what might be going on here? As said before, when I test from Eclipse on a SP server this problem is not existent at all! Any help greatly appreciated, Henrik

Ok, I first thought that passing a Chunk instance to my handler class would be sufficient. I get the Chunk from the OnChunLoad() event. I retrieve it from chunk using event.getChunk(). Not sure where I get the world from (chunk has a chunk.worldObj instance, is that what you meant?). Cheers, Henrik

Aaaaah okay, I was so stuck within searching for a method of the Block class because it said there were methods in the docs. WIth your hint I looked in the Chunk class (of which I extract my block) and sure enough, there is Chunk.getBlockMetadata(x, y, z) which I think does what I want! Thank you very much for the pointer, I was completely blind :-) I would also like to know what the daylight light value of that block is and Chunk seems to offer that, too: Chunk.getBlockLightValue() - but it takes 4 parameters which are undocumented (they're only named p_76629_1_ through p_76629_4_). Is there any way to find out more documentation of this method? If I could find out where the docs to stuff like this is I'd have to ask fewer dumb questions :-) Thank you again so much! Cheers, Henrik

Hey forum, so another newbie question from me: How does one get the metadata from a block object? I've read the tutorial and it says The problem is, I don't have the world, so I can't use getBlockMetadata. And I can't find a single method of the "many methods" that would return the metadata value. I get the ID by using Block's static method Block.getIdFromBlock(b), but there's no Block.getMetadataFromBlock() equivalent. If you could help me out, that'd be awesome. Thanks a lot! Cheers Henrik

Hey forum, so I'm writing my first mod and ran into another problem: I subscibe to eventChunkLoad and determine the surface of the chunks that I get. This works brilliantly in singleplayer (!event.world.isRemote). I can access and dump the data I need for my mod. Then I built a production JAR using "gradlew build", placed it in my MinecraftForge mods/ directory and tried the exact same thing with an MP server. There, it doesn't work, however: eventChunkLoad() gets called, and event.chunk() yields a non-null chunk, but chunk.isChunkLoaded is always false and the chunk doesn't contain any data. If someone could hint me as to what I'm doing wrong I'd greatly appreciate it. Cheers, Henrik

Thank you so much! Have an awesome day, Henrik

Aaaah! I see! Hadn't thought of that at all, thank you a lot. So since I don't want to dev on my remote server, how can I generate a JAR that I can include with my (production) Minecraft installation and drop into the mods/ directory of it? Cheers, Henrik

Hi forum, I'm getting started with Forge modding and want to start something minimap-like to check out the capabilities of Forge. I've already set up a basic skeleton that calls a hook when a Chunk is loaded (which looks very good so far to me!). That's pretty much what I wanted. But it only works when I do singleplayer. As soon as I try to connect to a MP server, it instantly crashes the game: [23:26:49] [Client thread/INFO] [FML]: Holder lookups applied Starting up SoundSystem...
