MCreator 2020.4 - The big summer update

The big 2020.4 update is out! It adds a lot of important new features such as enchantments, conditions, entity inventories, and much more, including many big bug-fixes. Read on!

Enchantments

The top-voted feature in the tracker in the time of 2020.4 development is here. Enchantments. Define new enchantments and use them as modifiers for your procedures.

Conditions

A new mechanic was added to procedures. Conditions. Use procedures that return values to conditionally spawn structures, ores, entities, use portals and ranged items, and more.

One of the uses for conditions is AI tasks of custom living entities too. Use conditions to conditionally start or continue execution of specific AI tasks.

FE energy and fluid-tank support

Another important new feature is FE energy support. Make custom blocks energy containers and use many new procedures to manage energy of custom blocks and blocks of other mods. Compatible with other mods too. Fluid-tank support for blocks and procedures for this system were added too.

Dimension improvements

Duplicating portals and portals not working properly bugs were fixed. Now portals support teleportation of any entity in 1.15.2 and are much much faster. Check the video below for a demonstration.

Block bases

Two new block bases were added: doors and fence gates. If you want your doors to have iron-doors like logic, set their material to iron.

Entities with inventory

Another feature added in this release is entities with inventory support. One can now bind custom GUIs to entities and the items from GUI slots are bound to the internal inventory of your custom entity. Procedures to manage slots at specific IDs of the entity were added too. They support vanilla entities as well.

The entity in range procedure

Another important addition to MCreator with this update is support to get the nearest entity of selected type in a given range or test for its presence. You can convert entities to items now too, which is demonstrated below in the example below.

Player variables

Entity NBT is not synced to clients so player NBT could not be used in overlays. To overcome this problem, we added player variables that are synced to clients properly so you can use this new variable type to add things like custom hunger, mana or other properties to the players.

Biome entity spawning editor

Biome entity spawning editor now supports much more than just listing entities. Set spawning type, weight, and group sizes with the new improved editor.

Damaging items in crafting table

Custom items can now not just be set to stay in the crafting grid when crafting but can be specified to damage themselves when used in the crafting recipes too.

Light-emissive blocks

Option to enable light-emissive block rendering was added. Now you can make blocks that visually glow in the dark similar to the magma blocks in Minecraft.

UI improvements

UI received some refreshing changes. A new list view mode was added to the workspace browser. Biomes and living entites now have representative previews based on their colors in the mod elements list.

New previews were added to many drop-down selectors such as advancement selector, texture selectors for living entities, armor textures, bullet textures, and more were added.

Release notes

• Existing custom biomes might need to have custom colors cleared to use default colors
• Global variables are now only synced from server-side to client-side and not the other way around to prevent malicious forging of data by sending packets with altered data from client-side to server-side
• Overlay and particle spawning conditions need to be redefined using the new condition system
• [Plugins] Data lists (eg. block and items list) can now be extended (eg. with elements from other mods), using plugins
• [Plugins] Plugins can now add texture maker, animation maker, procedure, and AI task templates
• [Plugins] Added option to define custom APIs, libraries, and support mods similar to how MCreator Link is implemented (APIs get automatically installed when enabled) and make procedures, triggers and AI tasks that require specific API enabled to work
