MCreator 1.8.2 - The performance update

The first MCreator update in the year 2019 is here. MCreator 1.8.2 is faster than any version before and packed with many new features and many bug fixes. Check it out!

Performance improvements

The first and one of the biggest improvements in MCreator 1.8.2 is its performance. To achieve faster build times, we now cache many parts of the code so they don't need to be recompiled. To do this, we have updated integrated Gradle to version 4.4. Workspace mod element format has been changed to improve build and workspace import times too. Code format tool and import organizer now have improved parsers too.

New workspace format and system

MCreator 1.8.2 changes the way mod elements are stored. They are now stored in JSON files instead of .mod files. The reason for this is because JSON is more readable and can be used by version control software.

Now each workspace has a fixed name too. On the creation of the workspace, a mod name and mod id are defined. Therefore the mod names are now fixed and not set at the export time but rather at the time of workspace creation. Now the export button simply exports the workspace based on the current workspace settings. Many new mod settings were added too.

Improved Custom GUI editor

Another big change is improved GUI editor. The UI has been redefined to be more user-friendly. Slot IDs can now manually be defined to match with your procedures. We have added a configurable grid that supports snapping so you can now make your GUIs much neater. Check it in action on the video below.

A new model management system

Custom 3D models are no more stored in mod elements. They are now part of the resources. The resources tab has been added that holds all the used textures, models and other assets of the mod. One of the tabs here is 3D models tab in which the user can manage custom 3D models. 3D models added here are then listed where they are supported and can be used, for instance in block maker at the selection of block model.

Rotatable blocks

This one has been in our todo list for ages. And finally, it is here. The user can now select multiple types of block rotation modes that result in different types of rotations based on the players' position. A new get players direction procedure block has been added too to expand the possibilities even further.

Smart recipes

In MCreator 1.8.2, recipes automatically get optimized. This means that now all the combinations of a recipe you define are now automatically possible, without the need for manually defining all of them. To see this in action, check the video below.

Important bug fixes

Many bugs were fixed in this update. All the bug fixes are listed in the list below, but more notable bug fixes are:
