MCreator 2020.3 - A feature-rich update

MCreator 2020.3 - A huge update

MCreator 2020.3 is here. It adds more features than any update so far. These include 1.15.2 support, Bedrock Edition Add-Ons support, inventory items, and much more. Read on!

Bedrock Edition Add-Ons support

MCreator 2020.3 is the first version that supports making mods (Add-Ons) for Minecraft Bedrock Edition. This means that now you will be able to make mods for all supported platforms (Phones, Xbox, PS4, Switch, ...) with MCreator. There are some limitations to this as Bedrock Edition Add-Ons are still an experimental feature in Minecraft, but many mods are already possible.

Minecraft 1.15.2 Java Edition support

This update adds full support for Minecraft 1.15.2. You can seamlessly update your mods to support Minecraft 1.15.2 with just a few clicks. As now multiple workspace types are supported, we have revamped the new workspace dialog too.

Improved new workspace dialog

Custom ranged items for mob attacks

Now you can select custom ranged items as ranged attack items for custom mobs. All procedures and properties will be inherited from the ranged items. You can use ranged items with procedures now too.

Connected sides support

This update introduces support for blocks with connected sides, similar to how to glass or ice blocks behave.

You can see new in-app help tooltips in action on the screenshot below too. Now almost all parameters and fields in the UI have in-app help available.

Glowing mobs

Another feature that was requested quite a few times is support for the glowing layer for custom mobs. A glowing layer is defined with another texture that controls glow amount based on the texture brightness.

Items with inventory

The most requested feature so far was added in this update too. Support for items with inventory, which makes mods like backpacks and portable furnaces possible.

Glass pane block base

We have added a glass pane block base that supports separate top and side textures for more customization options.

Source and target entity procedures

Source and target entity procedure dependencies are now supported. This means one can now detect both the entity that was hit and the entity causing the damage and run procedures on both of them, for example.

Underwater swimming mobs

New swim AI task was added and water mob entity properties and path navigation were improved. One can now make fully functional water mobs, both passive and aggressive.

Better key bindings

Key bindings now have a key released trigger. This trigger provides dependency for a variable containing the press time, so things like charge key bindings are now possible.

Improved key binding procedure triggers

Itemstack variable type

Support for both local and global itemstack variables was added. Now more complex crafting procedures and things like global chests can be implemented.

Itemstack variables

Item to block procedure

Items can now be converted to blocks. This is useful for machines like block placers that can now take an item from the slot and convert it to a block for placement.

Discord Rich Presence

MCreator now supports Discord Rich Presence. When you have Discord open, MCreator can now show the current workspace you are working on and its type. You can disable this option in preferences in case you don't want it too.

Fabric mod loader support

We have added support for Fabric mod loader based generators too. There is no official generator at this time, but we have worked with contributors Goldorion and crispy_chips1234 that work on the community-based generator plugin for Fabric loader. You can support, test, and help with their work on the forum topic for their plugin or on the project GitHub page.

Release notes

finally, 2020.3 is out now I can finally start [Access Denied: Level 12 access required: User has Level 10 Access]

i have a question.How my mob can throw more fireballs than one.For example three headed ghast?

Why dropped 1.12.2 support ? We still need it because 1.14.4 and 1.15.2 is not fully stable
I'm disappointed about this update...

Question: I have a workspace in mcreator 2020.2 on Minecraft 1.14.4 . What do I do to update to 1.15.2 on creator 2020.3? Do I just open it in the new Mcreator or is there a process I must do first?

I did that and it has been working on workspace setup for over 30 minutes and appears to have had an error during the "stopping gradle daemons" phase. Currently stuck on the "importing gradle process" step
