MCreator 2022.1 - Full Minecraft 1.18.x support

MCreator 2022.1 is here. It fully supports Minecraft 1.18.x, while also adding new features like nether and cave biomes, custom villager trades, and more. Read on!

Minecraft 1.18.x support

The biggest change in this release is full and official Minecraft 1.18.x support for Java and Bedrock edition. The generator builds on 1.17.x generator and improves it, so the code of this generator will be even cleaner and more performant than before!

Nether biomes

One of the most requested features we have seen in the past year is now here. Support for nether biomes! With a single check on a checkbox, you can now make your biomes generate in nether alongside other nether biomes. See a demo below.

Cave biomes

And nether biomes were not enough for us. So we have also added support for custom overworld cave biomes. Below you can see a custom cave biome we added to the Minecraft.

New built-in entity models

We have extended our offering of built-in models with the following new models: cod, ocelot, piglin, salmon, witch.

Entity model conditions

Alongside new models, new entity model conditions were added that allow you to procedurally make the entity transparent and/or shake similar to how striders shake.

Custom villager trades

You can now define custom villager trades. You can define new trades per villager profession, define trade level, XP levels of the trade and advancing price multiplier.

New ore generation parameters

New Minecraft 1.18 features allow for different ore generation shapes and levels below 0. We have made sure to support that for custom mods too.

Context menu for project browser

Did you want to easily add new items to your project file structure? To make this possible, we have moved the toolbar of the project browser to the adaptive context menu that shows different entries depending on the element you have selected. It adds some new features too, as you can see in the video below.

Underwater block parameter

You can now separately define a block that generates below the water in custom biomes. Before, the block that generated there was the underground block, but you can now optionally define a more specific underwater block if desired.

Better procedure list selectors

Did you happen to get the "undefined" list entries bug in procedure element selectors, such as entities dropdown? Well, this bug is now fixed, but we have also improved the selection process to include a search bar and icons for custom elements. Check it out in action below!

Entity local variable and return type

We have added a new local variable type: entity. This variable type can also be used in return values and called from another procedure. This should make writing complex entity selection algorithms, for example, easier.

Some new randomizer procedure blocks

You wanted random in-range procedures more easily and we listened. Now you can generate numbers or integers in range with a single procedures block. We have also added procedure blocks to obtain a random item from the item tag or a random block from the block tag.

Release notes

• [FG 1.18.2] Biome spawning is now greatly affected by weight, height base and variation, temperature, and rainfall chance. Tinkering with these parameters to achieve a good generation will be needed by most of the mods 
• The food mod element was merged into the item mod element. Existing food mod elements will be converted to items automatically
• Block position x, y, and z blocks were removed as x, y, and z blocks act like those by default when appropriate
• Changed the format of ranged item projectile entity registry name
• Workspace encoding was changed from system default to UTF-8, so on some computers, non-standard characters may need to be re-entered where they broke
