MCreator 2023.3 - Minecraft 1.20.1, item properties, NeoForge & Quilt support, tooltips and much more!

MCreator 2023.3 update is here, adding support for Minecraft 1.20.1, item properties, NeoForge and QuiltMC modding APIs, and many more new features. Check it out!

Minecraft 1.20.1

The first new feature of this update is support for Minecraft 1.20.1, meaning we now support the latest 1.20.x Minecraft release fully. We made sure to cover all things and update datalists that may have missing items from the new update.

Item properties

Probably the biggest feature of this update is item properties. With item properties, one can make a single item have multiple textures and/or models depending on the item state. It can be a vanilla state such as damage level, trim type, cooldown, and more, or a custom state defined with a client-side procedure.

If you are unsure what this means, you can see this feature in practice in the video below, where we created item that changes color depending on the weather in the world.

NeoForge & QuiltMC support

This update introduces readiness for two new modding APIs, namely NeoForge and QuiltMC. Readiness means support for them is not out-of-the-box, but MCreator can support plugins adding those modding APIs, similar to eg. Spigot or Fabric.

The new workspace dialog will now look like you can see in the picture below, with two additional selectors for the workspace type. By the way, our contributor Goldorion already made a NeoForge plugin, so make sure to check it out!

Damage source changes

This update also introduces some damage source changes. Damage source is now a dependency that can be used in existing procedure blocks related to the damage source. Existing procedure setups will be automatically converted to the new system.

Dimension igniter special info

This one is a bit smaller feature, but could be a nice touch to quite some dimension-related mods. You can now define special information for the custom dimension portal igniter item.

GUI tooltip component

We did not stop adding new GUI components. This time, we are introducing the tooltip GUI component. It is specified as a square region. When hovered over this region, a fixed text or text provided by a procedure is shown in the custom Minecraft GUI.

New feature blocks

The feature mod element is being actively developed. Part of this are weighted list providers, that allow one to provide a randomized choice with weighted probability. One can now provide a random blockstate, block, or integer property of a blockstate.

Some new advanced procedure blocks were added too. One of them is a block that allows one to specify additional placement parameters per feature. This goes hand in hand with the random feature from the list procedure block, so one can have different types of placements randomized. A random patch of the feature type procedure block has also been added, improving options for vegetation features that can now be generated in vanilla-like patches.

New global procedure triggers

Two new global procedure triggers have been added: entity blocks with a shield and entity uses a totem. Both are cancellable, meaning one can alter the behavior of shields and totems using them.

GUI slot ID dependency

GUI slot procedure triggers now pass slot ID as a dependency. This is very important as now one does not need to have different procedures for different slot IDs that are similar, but different so each slot calls the right one. Instead, one can now make a single procedure that is called by all related/similar slots and only slot ID dependency is checked in the said procedure. Advanced but handy feature :)

Added new int dependency to MCreator custom GUI slot UI components

Broader tag and wildcard support

Many will love this one. Many new mod element parameters now support tags and wildcard items (e.g. any dye, any stone, any glass color, ...), including repair items for custom armor and tool mod elements, blocks affected by parameter of special tools, replacement blocks for custom ore generation in block mod element, and compatible items list for custom enchantments.

Support for tags and wildcard selectors on more locations in the MCreator Minecraft mod maker software

Release notes

  • On stopped using triggers were removed from music disc and tool mod element as they do not work with those item types

Yes, finally 2023.3!!
That GUI Tooltip is interesting and made me need that feature lol, but tysm for this feature, I was currently working on GUI.
Great work you guys! :D

Awesome as usual! This will give us a load of immersive item ideas.
Another probably late question about entities: since 1.20.1 includes the camel entity, will there be some form (obv. no mod element feature, but wiht a bit of custom code) of support to allow multiple riders on a living entity? I'v long been trying to do something like this for my custom mounts but for now there didn't seem to be any good option since this feature was limited to tile entities, if I remeber correctly.

Amazing Update!! Excited to make some new trims!! :D
