MCreator 2020.2 - Debranding, plugins, slabs and more

Debranding, plugins, slabs, music discs, 1.15.x data packs, ...

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

Plugins in preferences

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.

New block bases

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.

Better flying mobs

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.

New recipe types

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.

Full Minecraft 1.14.4 support

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.

Improved GUI editor

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.

Music disc support

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 ;)

Furnace with NBT tags display

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.

New Java package structure

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

To apply the patch (fix these bugs and get the listed features), download MCreator 2020.2 again and install it over the current installation. If you have update notifications turned on, you will be notified of this patch automatically.

We have decided to release three patches this time to ensure MCreator 2020.2 will work smoothly for all the users that might use it for 1.12.2 modding in the future. We are aware patches are annoying so we are already working in the direction of supporting in-app updates and patches in the future.

Comments

Good update, but i still have my big where all entities, tile entities are all invisible 😭😭😭

Does this happen in your normal Minecraft after you export the mod too? I suggest to open a new ticket and give this another go, we might be able to find the cause this time ;) Just include as much as possible details in it.

BTW if u wonder why a coding manuel the reason is me XD I need one

You can already code in MCreator. There are plenty of manuals for Java on the internet, check them ;)

quick few ideas too add: a built in model maker (it allows the use of custom or already made Minecraft aspects to create the model also the ability to insert and edit models of current or your own models in Minecraft or your pc) an texture size changer (for a more HD mod) an coding Manuel (if you decide to add coding to something) an extra gui type that allows you to make it so players can choose a custom model type if they choose (its like you want to make a morphing mod or you want the player to wear custom hats) and final idea make it so you can fully customize your mcreator (customized backgrounds for the buttons change text color move button feature and more other customization options)

So, in this new update, is it possible to create mods for 1.15.2?

1.15.2 will come with the first 2020.3 snapshot

when I updated, all my mod elements ended up "not compiling correctly" because of the java code upgrade. could you possibly have a generator that converts 2020.1 files to 2020.2?

that converts 2020.1 files to 2020.2 - this is what MCreator does for you. If it did not work, open a support ticket and make sure to follow the tracker rules.

You are awesome ! I have the impression that in this update, everything that was missing has been added! XD Even if it's no longer mandatory, I will credit you all the time in my mods. Thanks again for this awesome mod creator!

You are welcome, but don't worry, there is still much to add ;)

I think the de-branding of things will help. I still however will ALWAYS credit MCreator in my published mods and put a link in the mod description next to my own online page...and donate for every mod I publish. I think the feature of plugins is an excellent idea! Being open source will allow for more features by skilled individuals. It's just like game manufacturers allowing mods for their games. It makes that game live on and be more than the original developer ever imagined. Good job.

Thank you, I am glad to hear you like what we do ;) And big thanks for supporting our project!

finally!!!! slabs!!! also i really love how theres new recipe types for the other furnaces cool touch!

Glad to hear you like it!

for some reason, the portal to another world does not work for me when I create it, writes: "your workspace contains mod elements that don't compile property" But I'm doing it right. What to do?

Search on the website for people with a similar problem first (check recent forum topics and tickets), if you are sure you did not find a solution there, open a support ticket and we will try to help there.

Getting an error with flying entities.

"The game crashed whilst ticking entity
Error: java.lang.ClassCastException:
net.minecraft.pathfinding.FlyingPathNavigator cannot be cast to
net.minecraft.pathfinding.GroundPathNavigator"

Can't go near them or it crashes.:( This breaks my dimension.

Just discovered that there is an issue tracker, I'll put this there instead.

For some reason it doesn't seem to download properly...
It comes up with errors about failing to write some files, and although at one point this didn't happen it then got stuck at Loading Generators: 1.12.2, and did this for over twelve hours (I accidentally left my computer on overnight), leading me to believe that it is not going to progress any further. Any idea why this should have happened?

I suggest you to reboot computer, uninstall MCreator, reboot again and then do a fresh install. This happened to some users and they reported this helped.

Ok, thanks :)
