MCreator 2021.1 - The accidentally huge update

The update that grew bigger than we planned - MCreator 2021.1. It adds 1.16.x support, folders, tinted blocks, and much more. Learn more about this update in this article!

As announced in the Minecraft 1.16.x and the future of MCreator, MCreator 2021.1 was planned to be mostly bug fixing update and the update adding Minecraft 1.16.5 support. Well, it turned out a lot more than that was about to happen :D

Minecraft 1.16.5

Probably the most important addition to the most users is support for Minecraft 1.16.5. Now Forge mods, data packs and add-ons can be developed for Minecraft 1.16 using MCreator. Data packs editor now supports adding custom biomes and dimensions too. Existing workspaces can be migrated from older versions with a matter of a few clicks, and MCreator will do all the work for you.

Workspace folders

Another very anticipated and largely requested feature we added in this update is support for workspace folders. You can now sort your mod elements in folders and keep your workspaces tidier than ever before. Combined with filters and sorting, now one can organize their workspace just the way they want it.

Tinted blocks support

Another feature we got a lot of requests for is support for tinted blocks. And we added it. For both plants and blocks. You can now specify blocks to tint with grass, water, sky, fog, and water fog colors. Items can have default tint applied too. In spirit of tinted blocks, we added new grass built-in model that has tinted grass overlay texture support the same way as vanilla grass does. Custom JSON models can specify tint index and thus become tinted too.

Customizable block bounding boxes

In MCreator 2021.1, you can specify block and plant bounding boxes of any shape. Not just any size of cube, but literally any shape. This is now possible with new bounding box editor that replaces the old inputs for block dimensions.

New dimension and biome features

Biomes and dimensions got quite some new features too. Biomes now support ambient particles in Minecraft 1.16.5 as seen in the video below. Additionally, custom biome music and sound effects can be specified.

Custom biomes now support multiple vanilla tree shapes and some additional parameters to control custom trees better. Make sure to tag your biome ground blocks as ground and/or dirt so trees can spawn on them.

Another improvement in the scope of biomes and dimensions is improved biome support in custom dimensions. Now biomes in custom dimensions will generate more properly in terms of terrain shape. Additionally, as shown in the video below, each biome can now specify own sky color.

Brewing and smithing recipes

Recipe support was extended with custom brewing and smithing recipes. See the video below to see a custom brewing recipe in action.

Custom smiting recipes can be specified for Forge mods, as well as for 1.16.x data packs and add-ons. See example of a custom smiting recipe below.

Entity tags

Another useful addition in this update is support for entity tags. With entity tags, you can extend functionality of your mobs with some of the vanilla mob capabilities. Addition of entity tag procedure checks extends this further by covering a whole group of tagged entities in custom procedures, which can greatly improve cross-mod compatibility and interraction.

Game rules

We have added a new mod element type called game rules. With game rules, you can add new world parameters that are accessed in the world creation menu and through commands. You can check game rule settings using procedures at any time. With this, you can add custom per-world configuration of your mod.

Wait procedure block

Another greatly requested procedure block was a general wait or as some called it - delay - procedure block. Now we added one. We still encourage you to use tick counter when possible instead of resorting to this block, but where this is not an option, new "wait X ticks then do" procedure block will do the task. All procedure blocks inside this block will execute with a delay of set number of game ticks. The caveat is that these blocks with only run on the server side, which means that some client-only procedure blocks will not work with the wait block (the procedure blocks marked with a tiny computer icon next to them).

Common Minecraft tags tool

There were often questions on our forums if custom logs belong to "log" or "logs" tag and what namespace to use. To resolve this confusion, we have added a new common tags tool that allows you to quickly add tag groups commonly used and specified by Minecraft. These tag groups extend functionality of your mod elements as described in the tool.

Sound previews

A minor but handy new features. When a custom sound is selected, a play button is enabled next to the sound selector that allows you to quickly preview the sound. Hold the button to play the preview which will then stop as soon as you release the button. Click multiple times to get randomized sound in case there are multiple sound files registered under one sound.

Entity tick global trigger

Although it is only a trigger, it is a very important new trigger. This global procedure trigger will run the procedure each tick for each loaded entity in the world. By checking the entity type or some other entity property in this trigger, one can heavily alter the game and the behavior of existing entities. This procedure trigger needs to be used with great caution though, as running too much procedures for each loaded entity can severely slow down the game if misused.

New translations

Last but not least, quite some new languages were added and existing translations greatly improved. Now the currently selected interface language is shown in the procedure selector, and the translations coverage percentage is shown in the preferences window within the language selector dropdown. Some bugs regarding rendering some of the letters for some of the languages were fixed too, providing a more friendly international MCreator experience.

Thanks to all the contributors

Big thanks to the people who opened all the PRs that made this update that huge, to the people who reported issues, looked for bugs, thanks to translators, tutorial makers, and everyone involved in the community. Your huge involvement motivated me to push myself a bit more and therefore things like workspace folders happened ;)

What now?

Now that MCreator 2021.1 is out, many of you are probably wondering what will happen now. Due to the global pandemic situation, it seems I will have time for another update and contributors agreed. So we are already working on PRs for MCreator 2021.2 that will add some new features and depending on the time of the 1.17 release, may support this version. 1.17 is of course entirely speculative as we do not know when the Forge will be ported to this version, but I do plan to update to 1.17 when the time will come. I will write more about the future plans in the future articles too, so stay tuned!

Tell us what you think about the update (and what your favorite new feature or bug fix is) in the comments! I am already looking forward to all new mods utilizing new features from this update :)

 

UPDATE: We have released a patch update to fix some bugs found in the 2021.1 release:
