MCreator 1.9.0 - The potion of the full screen and more

MCreator 1.9.0 adds some of the most anticipated features in the history of MCreator including full-screen support, custom potion effects, and custom armor models. Check it out!

New interface

The first thing anyone updating from previous versions will notice is that we have made some notable interface changes. MCreator now has menubar and toolbar with the most commonly used actions close to the mouse cursor. Instead of fixed tabs, MCreator now opens tabs as you open different tools. The interface can now be maximized (full screened) so you no longer need to work in a small window. Now MCreator feels like a true IDE!

We have introduced 3D previews of blocks with the default cube model, so you can now identify your custom blocks much easier in MCreator's interface and block selectors.

Potion mod element

The second most notable addition is a new mod element called potion. With this mod element, you can add new potions and potion effects. You can define procedures on what happens when the potion is applied, active and when it ends. You can define a potion name, color, image, and many other attributes.

Workspaces in folders

MCreator 1.9.0 introduces workspaces in folders. Users no longer need to select a workspace from 3 (or 5 if logged in) slots. Now one can have as many workspaces as he wants. Switching between them is a matter of seconds as each workspace has own gradle instance so no rebuilding is required when switching.

In later versions of MCreator, the user will just need to open the workspace folder with new MCreator. No need for exporting and importing workspaces.

We are also marking .mcr workspace file format legacy at this point. From now on it is not needed anymore as one just opens a workspace in a newer version without exporting it and importing it back. In order to still support moving workspaces, we have added a new sharable zip format which zips your workspace. One can import this zip file on another computer then, but there is no lengthy import process, just the extraction of the zip file.

MCR file format is now obsolete

As MCreator now stores workspaces in folders, .mcr workspace file format is no longer used. One can not export their workspace to .mcr file in MCreator 1.9.0. Upcoming MCreator versions will completely drop support for .mcr file format so if you have any old workspaces that you want to use in later versions, import their .mcr files in MCreator 1.9.0 to convert them to a new workspace in folder format, so you will be able to still work on them in later versions.

Custom armor models

Another important addition in 1.9.0 is support for custom 3D armor models. These models need to be JAVA models (same as for mob or ranged item bullet model). One can assign parts of this model to be parts of the armor model for specific parts of the armor.

Custom armor parts names support is added too. Now you can enable just some of the parts (was possible before) and give them different names than just body, leggings, ... (was not possible before).

Code editor improvements

Code editor got some nice improvements too. Code editor files now open in tabs as any other tool in MCreator 1.9.0. Code editor now features a breadcrumb on top of the editor and you can use this breadcrumb to navigate through files of the workspace.

Code editor can now edit any file of the mod element, not just the main Java file. This means that you can lock mod element and edit its JSON files and keep them locked too. When clicking edit code of the mod element button in the workspace, the user is now presented with the list of the files of the given mod element that one can edit.

Editable registry names and IDs

MCreator 1.9.0 adds support to change registry names and IDs of your mod elements. This way one can resolve many conflicts with other mods and change block and item registry names, for example.

No more incompatibility between mods

Due to this registry editor users can reduce the incompatibility probability. To totally resolve this issue, we have made a system that resolves dimension ID conflicts in case if conflicts still happen by assigning a different ID to one of the conflicting dimensions. Now each mod has own Java package too, so incompatibilities due to same mod element names can't happen anymore. The only source of incompatibility now is if two mods have the same modid.

Mob immunity options

This update adds more options to define mob immunity. Before 1.9.0, one could only make mob immune to fire. Now we have extended this system to support immunity to arrows, fall damage, cactus, drowning, lightning strikes, potions, and direct player attack (by hand or sword for example). This way, many new RPG dynamics will be possible and new boss mob types can be made.

Improved texture maker

Are you out of ideas for your textures? We have added a new randomizer tool to the texture maker to help you get the inspiration for your textures. Just hold the Randomize button and wait until your dream texture shows up. We have improved the layout of the texture maker UI too and added many new templates to make a variety of textures made with this tool bigger than ever before.

Block/item selector textures

In order to better comply with copyright terms of Minecraft and Mojang, we have remade all the textures for the block/item selector so we don't use the Vanilla ones. All the textures were made by our graphic designer Matej in hopes to make them as understandable as possible. Some of the missing items such as banners, tall grass, damaged anvils, and some others have been added too. Texture maker textures have been manually remade too.
