[1.14.4] Checking for specific blocks in loaded chunks


Recommended Posts

Does the block have a tile entity? Is it a block of your mod?

I'm just trying to grab the coords of normal vanilla block, for example iron ore or stone blocks. It's not for modded blocks.


I'm guessing I'd have to iterate through a chunk for that specific block, but I just don't know if that's possible / how I'd begin something like that.

You will have to search through the entirety of the chunk, which is slow.

About 600,000 nanos (provided you do literally nothing else but look, doing more can use up as much as another 600,000 nanos) and you only need to do it once per chunk after its generated. Player placed blocks you can acquired at the time it happens.


I would recommend using the Custom Ore Gen CogOreGenEvent (which is called after COG does its stuff, which is pretty much guaranteed to run Actually Last, though there are a handful of mods that go later) to do it, but that hasn't updated past 1.12 yet.


Or if you're thinking of doing it as a map, you pretty much scan the chunk when the map already does its thing to find out what color to draw. I've done that before too.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.


Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.


DO NOT PM ME WITH PROBLEMS. No help will be given.

What are you trying to achieve?

My plan was to make a VERY simplistic X-RAY mod. I do not intend to use it outside of this project or publish it at all, I just wanted to see how they worked programatically.

Most X-Ray mods work like the resource packs do. They just don't render the blocks that are not whitelisted. Do what you will with that information. They don't scan each chunk.


I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect.

Forge and vanilla BlockState generator.
