Infinite Terrain/Sprite Indexes... Finite Block IDs. Workaround?


Recommended Posts

Posted

Hello, I've been an aspiring modder for at least a month now, learning the ropes concept-by-concept.

 

Long story short, I've encountered this problem: I did the number-crunching and realized that, even with metadata-ing blocks, we can only load about 200-250 texture files if we assign all the block IDs to have one texture index per block's metadata value (4096/256 = 16, 16 x 16 = 256, less if we consider current vanilla Block/Item ID allocations). I know that MCForge is touted as having "Infinite Terrain/Sprite Indexes", but we're still limited by the ID arrays unless we go in the source code and mess with it. I don't want to do that, and would prefer a solution that doesn't make me have to do it.

 

The reason I'm having this problem is, to be truthful, I have a project in mind that uses more than 1,000 texture files, which is far and beyond the current capacity of the Block ID array. The blocks in mind will have no logic to them and are only intended for display. If anyone have any ideas to help me with this problem, it'd be greatly appreciated. :D I'm sure there's a possible solution and that I just haven't found it yet.

Hello,

I don't know if it is a good idea to use so many textures in any project. Say in OpenGL, there is only a finite number of texture units, which are used to sample texture data from memory. That means, in any given time only so many textures can be used by graphics card simultaneously, and any reassignment of them will change the state of graphics card, requiring synchronization/more cpu usage. In general, it is more efficient to use a small amount of big textures, than it is to use many small textures(see texture atlases)

Ah, that makes sense, thanks for that piece of info.  :)

 

Unfortunately, that wouldn't solve the primary issue, though that would help deal with a secondary one down the line. The real problem still stands in that eventually there's simply not enough Block ID array space to work with, not without going over Forge's head and modifying the array itself.

Redpower2 created by Eloraam has A LOT more than that, if you aren't familiar with the mod you really should before you set out to do something so massive, also it sounds like quite a huge leap as your first big modding project, maybe you should start simpler? ;)

 

In any case, in RP2 there is this saw which can cut any block into pieces, these can be set out into the world or cut into other pieces.

And you can do this for ANY kind of vanilla block + all the normal RP2 blocks!

Creating 43 different unique blocks for EACH normal block!!!

 

And then when you consider how many different blocks you can cut into these 43 different ways, the amount of BlockID's used should skyrocket! but no.. Eloraam uses only 1 block ID for ALL the 43*(number of cut able blocks)! One single bId for several hundreds of blocks. and also her mod is compatible with all other forge mods, so shes not ruining any base classes doing so, meaning it is possible for anyone to do it without modifying forge's base classes.

If you guys dont get it.. then well ya.. try harder...

    • im new to minecraft java modding and I am looking for some help on adding a custom dimension to minecraft java version 1.21.1   I haven't managed to find a good 1.21.1 minecraft dimension turtorial for intellij modding.  all I could find online is how to make the json files for the custom dimension but not how to setup the custom dimension in the game.    im using forge's recommended version for minecraft 1.21.1, any help would be appreciated
    • Thank you for the suggestion if figure that it should be able to support around 40 based on my previous experiences hosting but no one really seems to have a concrete way of figuring it out. You have been alot more helpful than most people and i will probably set up Linux tomorrow.
    • https://mclo.gs/e8nuqSA My friend and I are having the same issue with this pack. We're trying to play on BMC4 with a bunch of extra mods. The game loads up to 'mod gathering' and then crashes.

    • Graphics are irrelevant for a server. According to google, it should support 20-40. I literally asked it "how many players on a lightly modded minecraft server will a ryzen 5 2600 with 32GB ram support?" Maybe someone with some real world experience has further input. I can say without a doubt that if you run Linux as opposed to windows for the server operating system, you will get better performance and have more resources available to your server.
    • Could someone help me to figure out what's the problem?  I get this crash when I try to enter to a world in forge 1.12.2:  The game crashed: exception in server tick loop Error: java.lang.NullPointerException: Exception in server tick loop Error code: -1 here is the crash report crash-2025-07-15_20.44.02-server333.txt
