[Solved] Block Ids


Science!

Recommended Posts

I have an object that needs to store a block and an item in nbt. After a little bit of looking, I saw that both the Item and Block classes have a method to get an integer id for an item or block respectively, and to get the item or block back from that integer id. What I want to know is, is there a reason for me not to use these? I know that these days ids are dynamically allocated somehow or other, and what I'm worried about is the same id not always pointing to the same item/block. I'm *guessing* they probably won't change if the mods installed stay the same, but I'm particularly worried about what happens if the mods are updated, or another mod is added.

ID's don't change per world.

So if you have to store something in one world that will never need to interact with another world, use block and item IDs.

 

The preferable method, however, is to get the names of Items and Blocks from the Item and Block registries respectively.

BEFORE ASKING FOR HELP READ THE EAQ!

 

I'll help if I can. Apologies if I do something obviously stupid. :D

 

If you don't know basic Java yet, go and follow these tutorials.

When you say 'world', do you mean world as in the class World, ie each dimension is its own world, or world as in one server's instance of minecraft, complete with all dimensions? And yeah, I might just go with the names. I just figured if there weren't any downsides to the integer ids they'd save a tiny bit of memory vs the String names.

(That's why I think its more accurate to refer to it as a "save" or "world save")

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.
