MCreator 2023.2 - Minecraft 1.19.4 and more

The second update of the year is here, adding support for Minecraft 1.19.4 and many new features, while not forgetting to fix all reported bugs too. Read on!

Minecraft 1.19.4

The first new feature of this update is support for Minecraft 1.19.4, meaning we now support the latest 1.19.x Minecraft release fully with an improved code generator to make the generated code as clean as possible.

Villager professions

This is a big one. Requested for quite a while now, finally coming to reality. Option to make custom villager professions, defining their profession block, hat style, sound, name, and trades they offer.

Apple Silicon support

This one may not be important to everyone, but all users of Apple Silicion powered Apple devices will now be able to fully benefit from the performance of their CPU by running MCreator natively supporting AArch64 ARM64 architecture.

New worldgen features

The feature mod element introduced in MCreator 2023.1 has also received some new features. One of them is a custom geode feature, allowing one to place custom-define geodes anywhere in the world, as specified by the placement configuration.

This one may not be that shiny at the first glance, but even more useful. One can now define any configuration of ore generation. This allows one to expand basic ore generation defined in custom block mod elements to a much more complex and refined ore generation configurations with targets depending on block type, weighted randomized choices, and much more.

Speaking of randomized choices, we are also introducing new weighted list providers for heights and integers. This allows one to generate features with eg. different sizes or locations, depending on the weighted randomized chance.

VCS (remote workspace) plugin

As announced on our social channels, VCS has been moved to a community plugin. The reason for this move is as this feature is not the main feature of MCreator and was thus not really improved as much as we would want it to be due to the limited resources of maintainers. Now being a community plugin, it will be able to evolve and get new features and fixes much faster and will be able to grow a better community of users that actively use this feature.

Bounding box from JSON model utility

We are adding a button to generate the bounding box definition from a block JSON model, allowing one to define the bounding box of custom models much faster than manually entering each box.

Optional dimension portal igniter item

You can now optionally enable not just portal, but also portal igniter. This allows one to add portal igniter functionality to one of the existing items and at the same time disable the default igniter which is not needed in such cases.

New custom range melee attack AI task

One may be interested in having entities perform melee attacks out of the default bounding box of the entity. To achieve this, a new AI task was added that can be used to specify a custom melee attack range that can be larger than the bounding box of the entity itself, allowing for a wider variety of attack options.

Improved min and max value selectors

Places in the UI where minimal and maximal values could be set were not validated in all cases, allowing one to enter a smaller maximal value than the minimal value, possibly introducing bugs or Minecraft game crashes. We have replaced all those cases with improved selectors that prevent one from entering such invalid combinations and also improve the process of changing the value range.

Living entity step height functionality

MCreator now supports specifying the step height of custom living entities. At the same time, we have also added procedure blocks to get and set the step height of any entity, allowing one to modify existing entities or change the step height on the fly depending on custom entity logic too.

Procedure improvements

We have added side indicators to all procedure blocks needing them. These indicators (icons on the right side of the procedure block) show on what side they can run on, as some procedure blocks only work on eg. clients, and some procedures only run on the server side and do nothing when executed from a client-side-only procedure trigger.

We did not forget to include some new procedure blocks either. You can see some of the new procedure blocks in the image below. These include procedure blocks to check if there is a village at a given location, a raid happening at the location, procedure blocks to check the spawn coordinates of a specific player, and more.

New texture editor randomizer presets

This one is not that major, but is really useful. We have added new generator templates to the texture maker template generator. One can now quickly generate and prototype new block, ore, and gem textures that can be then used as a base or inspiration for new mod elements.

Release notes

• Vanilla creative tabs differ slightly between generator versions but target Minecraft 1.19.4 with namings
