MCreator 1.8.1 - Bug fixes, new features and more

MCreator 1.8.1 is here. After the previous update packed with features, it is time for a more bug fixing oriented update, but we didn't forget about new features in this one too.

Inline procedures

We have added support for inline procedures. This means that procedures can now be defined from the procedure selector like it used to be in the old event system. A standalone procedure is still created. All existing procedures can be edited from the procedure selector too. Check the gif below to see this in action.

Better element previews

New improved previews have been added for some mod element types including commands, creative tabs, key bindings, dimensions, and some other mod element types. With these new previews, it will be easier to find your mod elements as they now have much more representative icons.

New procedures and improvements

Procedure editor got quite a lot of new features and improvements. New procedure template library has been added with examples of procedures. We will grow this library in the future based on the user suggestions. Procedures can now be exported and imported with a new .ptpl file format. This will make it possible for users to reuse procedures and share them with other users.

These new procedure blocks were added:

• [#44032] Added entity type compare block to the procedure system
• [#42909] Added spawn XP orb procedure block
• [#44596] Added check difficulty of world procedure block
• [#43935] Added burn and extinguish entity procedure blocks
• [#44202] Added "call procedure at location" procedure block
• [#42698] Added "check harvest level of block at" procedure block

Many minor improvements

Many other minor improvements have been made too. One of them is improved mod element search that now supports filters - hover over the search box for usage tips. Multiple mod elements can now be selected at once. Selection can be made by dragging mouse too, which allows you to make a very specific selection of mod elements. You can see this in the action below.

Another new feature is redesigned mod element type selection. Now the selection of new mod element type is easier. When clicking add button, a sorted dropdown of mod element types is shown. We have added new more logical shortcuts for mod element types too, so after pressing + button, mod element type can be selected only by pressing a shortcut letter.

Other new features include improved animation maker, option to skip mob model animation definition, option to define smelting recipe's XP output, generation of custom fluids as lakes, option to make custom food always edible, code editor improvements and many other.

On the picture above, you can see the lakes made out of custom fluids as this is now an option in custom fluid creation.
