MCreator 1.8.3 - Community requested features update

MCreator 1.8.3 is all about the features requested by the community. While we listen to the community each update, this one is really focused on fulfilling as many requests as possible.

Mac and Linux version improvements

We have improved the Mac and Linux versions. Now they come with bundled Java so there is no need to mess with JAVA_HOME parameters, Java versions and other troublesome configuration that was required before. The installation procedure has been improved for both platforms too.

More variable types

We have added new variable types in MCreator 1.8.3. New variable types include:

• block specific variables that are stored with the game save
• entity specific variables that are stored with the game save
• dimension specific variables that are stored with the game save
• world save specific variables that are stored with the game save

OBJ models with UV textures

Another important addition in MCreator 1.8.3 is support for OBJ models with UV texture maps. MCreator will automatically detect UV mappings and open a texture mapping dialog upon importing such models. There are some limitations to this, however, more on this on OBJ models wiki page.

New entity procedure blocks

Many new entity related procedure blocks were added. Some of them are: get entity coordinates, velocity, health, is sneaking, burning, sprinting, riding, being ridden, current entity dimension ID and display name of the entity. These procedure blocks should add many new options and possibilities to MCreator mods.

World generators improvements

We have added dimension and biome restriction options to all world generators so now the world generation can be much more specific and diverse. Structure spawn mod elements got some improvements too, including spawning height offset and option to randomize spawning rotation. Example of the newly revamped block spawning options panel can be seen on the image below.

Multiplayer compatibility

In this update, we have fixed many issues with multiplayer/server compatibility. Before 1.8.3, custom mobs crashed Minecraft server. This bug is now fixed. Many procedures caused the Minecraft server crash too. A new trigger side indicators were added to indicate which events are triggered on client side only and therefore not directly server compatible.

Release notes

Here are some release notes for the users updating from the existing workspaces from older versions.

Entity dependency on block procedures

Some block (and plant and fluid) procedures used to have entity dependency on procedure triggers such as when block added to the world, when block explodes, when the neighbor block is placed, block tick update and similar procedures. This entity was loaded from the client side and this caused many mods to not work on servers. Now we have decided to remove entity dependency on these block types.

It does not make much sense to have entity dependency on these events as one can not determine which entity (if any) has added the block to the world - it could be placed by world generator and we can't link this event to any entity.

If you used entity dependency with this kind of procedures, you mod might not compile when importing older workspaces in 1.8.3. To fix this, just edit and go through all steps of these mod elements to redesign the procedure triggers to not call procedures that do not provide the entity as a dependency anymore.

Improved Minecraft Forge code format compatibility

MCreator used to generate a code that would not follow some of the rules of the Minecraft Forge code style and mechanisms. As MCreator is seen as a learning tool, it is not good to give bad examples on how the code should look like. Therefore we have decided to improve this. From MCreator 1.8.3 on, the generator will make more compatible code.

Some of the changes include event-driven registration of blocks, items, biome, and entities. Mod element model registration was improved too. Many changes to improve server compatibility have been done too.

One of the consequences of this is that we have done some changes on the way mod elements are registered too. Because of this, users will need to unlock all the locked mod elements so the code is regenerated with the new format and then apply their changes to the code again.

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:

• [Bugfix #47700] Custom mobs were crashing Minecraft Server

UPDATE 22. 3. 2019, 18:45 CET

There were some bugs found in 1.8.3 so we decided to release a patch update. If you are having one of the following bugs and downloaded MCreator before the time of the patch, consider reinstalling MCreator 1.8.3:

• [#47784] Custom blocks with log rotation placed by tree or world genertator or by procedures have broken model texture
• Armor texture selector is not showing textures

To apply the patch (fix these bugs), uninstall MCreator 1.8.3, download it again and install it again.

UPDATE 28. 3. 2019

There have been some issues with MCreator and Avast detecting false positives with MCreator. We have contacted them and the issue is now resolved so users can now use MCreator 1.8.3 without having to disable their antivirus.
