MCreator 2020.2 - Debranding, plugins, slabs and more

MCreator 2020.2, one of the most important updates with some big changes is here. Debranding, plugins, slabs, 1.15.x data packs just to name some. Read on!

Debranding and new license

One of the most important changes in this update is the option to completely customize your mod and remove MCreator branding. MCreator now allows full debranding of your mod (custom package name, custom credits text and no prefixes of class names). New simplified distribution terms are now in place too that do not require you to credit us and we do not impose any restrictions on the distribution of the mod. From the updated EULA:

The user is allowed to distribute their exported mods freely under their own terms or licensing. The user is required to abide any other laws, licenses, and terms that apply to them as a Minecraft mod/add-on author (e.g. Minecraft EULA, Minecraft Forge license, ...).

You are not required to credit us, but we still encourage users to spread the word about MCreator and consider donating to us, as only with your support we can keep this project alive and not stall it.

Plugins

Another important new feature is plugin support. You can read more about plugins and see an open-source demo plugin to help you get started if you are interested in plugin development here: https://github.com/Pylo/MCreatorDemoPlugin 

With plugins, we are giving the users the option to add new features in MCreator before we do or add functionality support for other APIs or similar. Right now, new procedure blocks, triggers, categories, AI tasks, AI categories, advancement triggers, and new code generators can be defined using plugins. Plugins can be seen as an "experiment" on how many developers willing to help and work on MCreator we have over the community too, to see if open sourcing MCreator in the future would make sense.

New block bases

Three new block bases were added: fully functional slabs, trap doors and leaves that have a working decay mechanics.

Better flying mobs

The following two issues were fixed:

• [Bugfix #53289] Flying mobs did not attack even if specified so
• [Bugfix #53289] Flying mobs did not rotate

Now custom mobs will properly attack the player if the do flight attacks AI task is added to the AI tasks list.

New recipe types

All currently supported data pack recipe types were added and are now supported in Minecraft Forge 1.14.4 and both newly introduced 1.15.x and 1.14.x dapa-pack generator.

Full Forge 1.14.4 support and 1.15.x data pack support

MCreator now fully supports Minecraft Forge 1.14.4 including working fluid buckets, fluid physics and OBJ model support for both blocks and items. Support for 1.15.x data pack creation was added too.

Improved GUI editor and inventory logic

GUI editor got some improvements too. Now the GUI creation process is a bit more simple as definition of inventories and binding slots to inventories is no longer needed. GUI's do not need to be bound to a block anymore, now blocks bind to GUIs. Blocks bound to the GUIs offer to open them on right click parameter without the need of a procedure to do this.

GUI slot management procedure blocks now work properly with GUIs so things like crafting GUIs on item right click or bound to any other procedure are now possible.

Music discs

MCreator 2020.2 adds music dics support. One can now define new music discs and register procedure triggers related to the music disc logic. We have added a new music disc texture generator in our image making tool too.

NBT tags in UI components

NBT tags can now be displayed in custom GUIs. An example of this new feature can be seen in our custom furnace we designed for this purpose. Stay tuned as we are working on some new tutorials on our YouTube channel, this furnace being one of them ;)

Improved generated Java code

Another major improvement in this update is that now MCreator splits the generated code into proper packages based on the functionality of the mod element and even splits some mod elements into multiple classes.

Release notes

• All mod elements with locked code (including main mod files) will have to be redone due to massive change in the project structure
• Blocks are now bound to a custom GUI instead of GUIs being bound to blocks
• Minecraft 1.12.2 is now marked as a deprecated version
