1st MCreator 2024.1 snapshot - Minecraft 1.20.4

MCreator fully supporting Minecraft 1.20.4 has arrived. Alongside the new Minecraft support, we improved performance and added new tag tools so make sure to check this snapshot out!

3 Minecraft versions?

As we did a few last times when porting to a new Minecraft version, MCreator 2024.1 snapshot supports Minecraft 1.19.4, Minecraft 1.20.1, and Minecraft 1.20.4 at the same time. In the next snapshots and in the full release, we will only cover two versions due to the high cost of maintenance of more than two generators.

What is NeoForge?

So you may have already noticed by now that the Minecraft 1.20.4 generator in this snapshot is not based on Minecraft Forge modding API, but on NeoForge modding API. In the past few months, a significant part of the Minecraft Forge team forked into a NeoForged project and they are now working on a new system that we have decided to adopt based on the public pointers regarding future adoption plans of other modders and Minecraft mod users, and on the improvements the project aims to introduce into the API.

Snapshot release notes

• Mod base files locking system was replaced with custom user code blocks. Existing code will have to be manually migrated to code blocks.
• Themes can now define images in either SVG (recommended for HiDPI and Retina screens) or PNG format. GIF format is no longer supported. Some icons were renamed and/or removed.
• Tags are now managed in a workspace tab. Existing tag mod elements will be converted to tag entries automatically.
• Deal custom damage procedure block was removed. Existing procedures will be converted to deal a generic-type damage. Custom damage types should be now used to provide custom damage messages.
• MCreator now requires plugins to specify the exact versions of the software they work with. Plugins need to specify the array of versions they support.
• Attack damage value was adjusted so UI and in-game values match for item and tool (sword, hoe, special, multitool) mod elements. Manual adjustments may be needed.
