MCreator 2024.4 - A new era of modding

Published by Klemen on
MCreator 2024.4 - Minecraft resource pack maker, vanilla entity animations, and more!

The last update of the year is here, and we are ending 2024 with a blast! This release is packed with tons of new and exciting features. Read on!

Minecraft resource pack maker

One of the biggest new features of this update is MCreator expanding to a whole new field. One can now make resource packs using our Minecraft mod-making software! Resource pack maker features a completely different UI where the structure of vanilla resources is shown, together with several utilities that allow one to modify and override those resources using our built-in image editor, code editor, and more!

MCreator is now also a Minecraft resource pack maker - it is becoming a multi-purpose Minecraft modding toolkit

The resource pack editing was also added to regular mod workspaces, so one can easily override vanilla resources as part of NeoForge or Minecraft Forge Minecraft mods too.

Custom animations for entity models

Another major new feature of this update is support for vanilla custom entity animations, which means for entities, the Geckolib MCreator plugin is no longer needed. Vanilla animations can be exported from Blockbench and imported into MCreator. See an example of such animation below.

Below you can see how animations are defined in the living entity editor. Animation specifies speed, amplitude, if it is walking animation and optional condition procedure that defines when the animation should happen. We highly recommend using animations in combination with "Saved sycned entity data" feature. Both vanilla Minecraft and custom animations can be selected and used.

In order for one to be able to use custom animations, a new tab was added to the Resources section where custom Java animations can be imported. One animation file can contain multiple animations, which is also indicated on the list.

One can also import custom animations that can then be applied to custom Minecraft entity models depending on the selected conditions

Sapling plant type

We are introducing a new plant type - saplings! Yep, now one can make custom saplings with just a few clicks. This also allows one to specify feature that grows from the sapling with quite some configuration around that, allowing things such as big trees and flowered trees.

See an example of two-by-two sapling that usually grows into big/large tree below, just that in our case, it grows into an end portal :D

Texture sprite component type in GUI

A new GUI component type has been added - texture sprite. With it, you can use sprite/tiled texture to show different textures on one region. Combined with procedures, one can make dynamically changing images (e.g. mana bar, progress bar, ...).

GUI component locking

This update adds quite some user experience improvements, and this feature is one of them. With it, you can lock certain components of GUI or overlay from moving, making sure you don't accidentally drag them around.

New fluid visual parameters

Fluids have received some new interesting parameters, including an option to specify overlay texture that is overlaid over the player's view when submerged in the fluid, as well as an option to enable fluid fog, specify fog color, and even specify fog start and end distance, as well as procedurally configure it, allowing for some interesting fog effects.

New Minecraft fluid visual parameters including overlay texture and fog color and render distance

This will make custom fluids much more immersive, as the fog and overlay texture will neatly complement your custom fluids. See an example below!

Waterloggable plants

We already mentioned plants got a new type, but that is not all. Plants can now be configured to be waterloggable, finally allowing one to make proper underwater plants. We can't wait to see all the new mobs populating the underwater worlds with new fauna.

MCreator 2024.4 also adds a new parameter to custom Minecraft plants that specified if they are waterloggable or not

Data pack test Minecraft client

Starting with Minecraft 1.21.1, MCreator now supports running your test data packs from MCreator itself. No more need for exporting the mod and installing it locally every time you want to test out changes. Instead, now you just click the play button, and Minecraft with your data pack loaded and refreshed in all existing and new saves will be prepared for you by MCreator!

MCreator now supports testing data packs directly from within the Minecraft mod making software

Minecraft game execution CPU and memory monitor

We have reworked the test client experience with a new Minecraft performance monitor, that continuously monitors CPU and memory (RAM) usage of the game, allowing one to quickly identify what game aspects load the computer the most, and will also allow users to identify if recent changes in the mod introduced too much burden to the resources. How cool is that?

Item special info improvements

Item (and block) special info got some improvements. The first one is that now, hard-coded special information entries are translatable. Existing entries will automatically be added to the Localization tab for you to translate. Now, all parts of your mod can be translated!

Special info of custom Minecraft items is now translatable

We have added a new procedure block to add a new line to the string. While this alone may not be that much of a feature, we have also added support for new-line handling in dynamic special info. More below.

Multiline procedure-based special info of items is now possible in MCreator

This allows one now to have dynamic item special info that extends across multiple lines, allowing multiple lines of dynamic content in the tooltips.

New dimension parameters

We did not forget about dimensions either. We are adding many new parameters to help you make your dimensions more unique. Noise size can now be scaled vertically and horizontally, sea level can be specified, and one can also disable ore veins or aquifers (fluid placers) if needed.

New dimension parameters in Minecraft mod maker allow one to scale the noise values

But that is not all, other new parameters were also added: fixed time, coordinate scale, infiniburn blocks tag, use the default/custom effects, has clouds, cloud height, sky type, does sun height affect fog, ambient light, piglin safe, has raids, monster spawn (block) light limit

Even more custom Minecraft dimension parameters in MCreator

Referencing 3rd party mod elements in tags

Integrations with 3rd party mods are getting even better. Now, one can reference mod elements such as blocks, items, entities, and more from third-party mods in custom tags. This allows one, for example, to check if a certain entity is of type from an external mod, add items and blocks from 3rd party mods into recipes, and much more!

Referencing external 3rd pary mod elements is now possible in Minecraft tags in MCreator

Music discs merged into item mod element

The music disc mod element was merged into the item mod element. Existing music discs will be converted to items automatically. This change now allows one to make a music disc that can be eaten, has ranged attacks, melee damage, and has inventory for storage, for example :D

Music discs are now part of the standard Minecraft item mod element type

Worldgen feature placement generator tool

Have you struggled to make valid placement definitions for your custom features? This is no longer a problem, as MCreator 2024.4 will feature a tool that will allow one to just specify their desired feature placement using a wizard, and it will generate the placement block definition for you. The tool will make sure the blocks are placed in the correct order and with the right values for everything to work as intended.

Potion effect modifiers

Now that custom attributes are a thing, we have added support for specifying attribute modifiers as part of custom potion effects, that are applied for the duration of the effect to the entity that had the effect applied.

Custom potion effects can now specifiy a list of attribute modifiers

Custom creative tab order editor

Now, one can not only specify the order of items in tabs, but the order of the tabs themselves too. Make your mod tab elements organized neater than ever before by having full control over them.

One can now alter order of custom Minecraft creative tabs

Block state property system improvements

Block state property system has received some upgrades too. MCreator now indicates the number of possible state property combinations, making sure one does not define too many combinations, as this can severely impact the game performance or even crash the game.

We have also made it possible for custom blocks to reference existing pre-defined vanilla block state properties, allowing better cross-mod and vanilla compatibility, as using existing properties ties block better into existing game mechanics.

MCreator now supports specifiying vanilla block state properties too and also shows combination count

UI improvements

Last but not least, we have done some small UI and UX improvements across the interface, so it looks a bit prettier and works better with both UIs with background images and without them. Can you spot all these new details?

MCreator also got some small but neat UI changes and improvements

Very very nice update ! This is going to make my mod making journey even easier! But is there any way to make block animations without geckolib ?

hi, how could i make the attack animation run when the entity attacks.

The world cannot be opened when adding a jigsaw to a structure. It fixes itself when I remove the jigsaw

What about model layers of entities? They don't seem to animate like the base model at all. Is this intentional or not?

So upon further checks, "Default" model is animated (same as base entity), so you can do things like change texture of animated model.

However, extra pieces using "custom" models can't be animated, as they would need own animation definitions and conditions for each piece, which is currently not possible.

Hey, I dunno if anyone else has experienced this, but about two major updates ago, projectiles that would explode on touching blocks or entities could be fired with the "Shoot arrow of type" code block without issues of exploding on the player or other. However, since then, items with a procedure to fire multiple projectiles at once for some reason have one projectile go forward, and the rest to launch up into the air at very low velocity in some random direction, and any fired projectiles either by "ranged item properties" or by a procedure would either explode instantly inside the player or explode randomly midair at some arbitrary point. What is causing this? Is this an issue I can fix or can you check up on what's causing this?

Honestly, I think this update is amazing, but the animation part is a bit confusing and very limited. I wished they incorporated something like Geckolib's animation thing where you can pick a swing/attack animation, idle, walk etc.

9.5/10 update

The vanilla system has walk and other animations, it was designed like that by the game authors.

You can achieve swing/attack animation, idle, walk etc. animations by conditions.

Tutorial maker NorthWestTrees has a tutorial in the pipeline

my favorite features: Sapling plant type, Texture sprite component type in GUI, Waterloggable plants, Referencing 3rd party mod elements in tags, Worldgen feature placement generator tool

Looking forward to updating my fluid mod with this big thanks! I'd love to see more block bases when you guys next get back to it so we have an easy way to make custom slime blocks for example. Connected textures and models would be my second wish if its possible to make. Look forward to seeing what you add next!

I would like to point out that despite scale being a vanilla attribute, which can be seen on the official Minecraft wiki, it is not an option in the attribute modifier selection for custom potion effects. It would be greatly appreciated if the you guys could change this.
