1st 2025.1 snapshot - Minecraft 1.21.4 support

1st 2025.1 snapshot - Minecraft 1.21.4 support

The first snapshot of the year 2025 is here. We are entering it strong with support for the latest Minecraft version and many new interesting features!

3 Minecraft versions?

As we often do when porting to a new Minecraft version, the 1st MCreator 2025.1 snapshot supports Minecraft 1.20.1, Minecraft 1.21.1, and Minecraft 1.21.4 at the same time. In the next snapshots and in the full release, we will only support two versions.

Minecraft 1.21.4 tags warning

Starting Minecraft 1.21.4, tags are much more sensitive. Referencing tags that don't exist in your workspace (e.g. from external mods) will cause the game to crash. Similarly, tags that reference elements from another mod and if those elements don't exist, such tag will not load. In practice, this means that mods may need to have the mod your mod is extending present in the development environment too. To do that, you can put additional mods into run/mods folder.

What about Minecraft 1.20.1?

Full versions of MCreator only support two versions. This time, we have decided to drop support for 1.20.1 in the full release. While the snapshot still supports it, the full release won't.

The reason for this is that later versions contain functionality and systems that allow us to add new features that won't work in 1.20.1. This means such features can't be added until we don't drop the support for older versions. Another reason is that we can't fully properly maintain that many versions at once with the current developer resources.

The good news for all modders who want to stay on 1.20.1 is that we will provide an official plugin for Minecraft 1.20.1 for MCreator 2025.1!

I think I know how to make a boat...
Make an Entity with a Boat Model and make it rideable
but This may cause Gradle error
So add BOATS

I'm not seeing the bugfix for the render thread problem that is happing with Forge mod and not seeing forge being updated for the newest minecraft version it's been four updates now that forge can only be use for 1.20.1 version, AND don't give me that silly reason that's it's the plugin problem, I'm making a mod for a person that only uses json/lava models not geckolib so don't give me that silly reason

Can you add that when you create a Wood pack it already has the crafting table recipe? and also that in the pack creates a door and a trapdoor too?

Thank you for keeping Mcreator 1.20.1 Forge!
Plz keep updating that plugin for versions past this.

Also, add more tags like (iron replacements, diamond replacements, custom sticks) and whatnot.

This may be hard, but I STRONGLY suggest you add the agility to change dimension height and depth(It's possible, but you've gotta do some code digging), and also an easier way to get silk touch. (It's frustrating to make a loot table every time I want silk touch)

They could've add like overwriting vanilla things e.g items, biomes, entity, blocks, etc. I thought 2025.1 might contain it but no

You can overwrite many things already using tags and global procedure triggers.

Btw there is no need to guess what certain version will contain as you can always monitor changelog (https://mcreator.net/changelog) to see what we are working on ;)

I don't know if I should leave this on the github page or here, my mod works fine in this snapshot on the 1.21.1 version but when converting it to 1.21.4 I get the code too large error will the way the code gets handled change in the full release so 1.21.4 can handle as many modded items as 1.21.1 or will I have to split my mod in 2 for future versions?

Now we need updates for the bedrock side of things! Like creating functions, changing textures and other stuff that we should be able to do.
