I'm making a mod with randomly generated blocks, so I need them to be registered just before entering a world. This way I can use the world seed as the seed for my generation code. Otherwise block id's are going to get screwed up, especially with multiplayer worlds.

 

When are blocks registered, and is there any way for me to do this?

Would it be possible to do that? I mean, if that were the case, we wouldn't really have an issue with Block ID's at all. We could just have one Block class, and just modify it's properties to be any other block. I think I need them to be registered because they will be used in crafting recipes and such. I can't imagine being able to keep track of all the properties as they move around.

The goal is to add more ores by randomly generating the base values of the ore (Harvest level, name, resistance, the strength of tools and armor, etc.) and also giving them "magical" effects similar to ARPGs like Diablo and Torchlight. I can already take a lot of effects from potions and enchantments, but I also plan to add other effects which are still a little nebulous at the moment. I should be getting some people together to plan the effects and rarities out this week; I just started writing intial backend code yesterday.

 

I think I see what you're saying, I can use up a few IDs just for the things that need to be changed at registration, and I think the rest I can allow variation in the code. I just need to worry about how they are going to stack in inventory and stuff like that. Also, they probably won't show up in the creative menu, and giving yourself an item through commands would be totally random. But I think that that's a reasonable price to pay to not use an absurd amount of Block IDs.

 

Hopefully that explains a little bit about what I'm trying to do, I tend to ramble a lot when I explain things like this.

 

EDIT: Also, what exactly are NBT values? Is there somewhere I can go to learn more about how to use them in Minecraft? I've only just started modding Minecraft, so I'm still getting the hang of how things work.

NBTs are Minecraft's in-game storage format, and you can use a TileEntity (not sure about blocks) to save data directly to them. So you really only need one block, and all the properties can be set via NBT.

Protip: try and find answers yourself before asking on the forum.

It's pretty likely that there is an answer.

 

Was I helpful? Give me a thank you!

Tired of waiting for mods to port to bukkit?

use BukkitForge! (now with a working version of WorldEdit!)

      Anybody know how to make tiered block and items? Back then it was much easier. Read for more info

      By Azarsra · Posted

      Back then there was a number which determined the tier of an item and block. If the block tier is lower or equal to the item number, the block would be mined. this however, has changed and now it goes by "needs_netherite_tool" which is fine, until you realized that some mods had items and blocks that exceeded these values. You can make you own "needs_mod_tool" but I feel that this is more limiting(and just more work) than before. So is there anyway to use something similar to the old tier system while also still being compatible with a lot of other mod tools?

      My server only crashes with the Ticking entity error

      Well, when I log in to the server, sometimes within an hour, sometimes within a minute, the server closes and informs me that there was a Ticking entity error. Below is the crash report

      screen recording problems

      By sailed · Posted

      Try switching to Windowed or Borderless Window mode in Minecraft. These modes make it easier for the recorder to capture gameplay, as it still has access to the display without the game taking up all of the graphics resources.

      Forge 55.0 Minecraft 1.21.5

      By Jonathing · Posted

      Forge version: 55.0.0 Minecraft version: 1.21.5 Downloads: As this is the start of a new version, it is recommended that you check the downloads page and use the latest version to receive any bug fixes. Downloads page Intro: Good evening! Today, we have released our initial build of Forge 55.0 for Minecraft 1.21.5. 1.21.5 is the newest member of the 1.21 family of versions, which was released yesterday on March 25, 2025. As a reminder, the first minor (X.0) of a Forge version is a beta. Forge betas are marked as such on the bottom left of the title screen and are candidates for any breaking changes. Additionally, there are a couple of important things to note about this update, which I've made sure to mention in this post as well. Feel free to chat with us about bugs or these implementation changes on GitHub and in our Discord server. As always, we will continue to keep all versions of 1.21 and 1.20 in active support as covered by our tiered support policy. Cheers, happy modding, and good luck porting! Rendering Refactor For those who tuned in to Minecraft Live on March 22, 2025, you may already know that Mojang have announced their intention to bring their new Vibrant Visuals overhaul to Java in the future. They've taken the first steps toward this by refactoring how rendering pipelines and render types are handled internally. This has, in turn, made many of Forge's rendering APIs that have existed for years obsolete, as they (for the most part) can be done directly in vanilla. If there was a rendering API that was provided by Forge which you believe should be re-implemented, we're happy to discuss on GitHub through an issue or a pull request. Deprecation of weapon-like ToolActions In 1.21.5, Minecraft added new data components for defining the characteristics of weapons in data. This includes attack speed, block tags which define efficient blocks, and more. As such, we will begin marking our ToolActions solution for this as deprecated. ToolActions were originally added to address the problem of creating modded tools that needed to perform the same actions as vanilla tools. There are still a few tool actions that will continue to be used, such as the shears tool action for example. There are some existing Forge tool actions that are currently obsolete and have no effect given the way the new data components are implemented. We will continue to work on these deprecations and invite you to chat with us on GitHub or Discord if you have any questions.
