Modding

• Renamed sprite and animation properties for sprite dicing from "slice", "slice_x" and "slice_y" to "dice", "dice_x" and "dice_y", because "slice" collided with property of rotated animation definition used for defining spritesheet sliced into multiple files.

0.18.37

Date: 29.07.2020

Major Features

• New blueprint library GUI. Its user interface had been aligned with the way inventory works in as many ways as possible. (https://www.factorio.com/blog/post/fff-356)

Features

• Added blueprint building from the map view.
• Blueprints can have snapping dimensions specified. When they are built by dragging, they are only built in the grid relative to where the build started.
• Blueprints can have absolute map snapping specified, so the blueprints are always aligned to the global grid.
• Blueprint books can be inserted into blueprint books, cycling through the books works in a hierarchical way.
• Upgrade planners and deconstruction planners can be inserted into blueprint books and the blueprint library.
• Blueprint books, upgrade planners and deconstruction planners can now have custom icons specified.
• All blueprints tools have an editable description.
• Added Blueprint reassign tool. It allows to set new contents of a blueprint by world selection.
• All blueprint tools have a copy function.
• All the blueprint tools are usable directly from the blueprint library.
• Quickbar links to blueprint tools are persistent when moving them between library shelves and inventories.
• Most of the blueprint tools manipulation in the blueprint library is part of a multiplayer latency hiding.
• Icons on the blueprint tools and filters in the upgrade planners/deconstruction planners are preserving the original values so whenever the mods would be re-added, the original values can be restored, unless the player clears the related icons manually.
• Any blueprint contents that are not available due to mod removal are also kept in the blueprint persistently, so blueprints can be copied and transferred in multiplayer without losing its original data.
• Added downgrading feature to upgrade planner. It works on blueprints, books and also when applying in the world.
• Clicking an upgrade planner button in the blueprint or a book now provides a list of all available upgrade planners to be applied.
• Upgrade planners now also update the relevant icons of blueprints and books.

Minor Features

• Grabbing an item from a blueprint book has the same hand item functionality as when holding an item from inventory, so it goes back to the original position when clean cursor is triggered.

Gui

Optimizations

• Fixed blueprint preview icons rendering scale when blueprint was held in cursor.
• Fixed that blueprint was not detecting modded data to be lost when loading unless one of the top level entities or tiles were to be lost. This means, that a blueprint with vanilla constant combinator (for example) with a modded signal will no longer silently lose the modded signals on resaving the blueprint storage when the mod is not currently active.
• Fixed that biters when faced with a rock might get stuck in an infinite pathfinding loop. (more)
• Fixed that clicking a technology in the research queue, holding the mouse down and moving it over the cancel button would make the cancel button flicker. (more)

• Removed the "particle" prototype type.
• Added the "optimized-particle" prototype type.
• Added the "burner-generator" prototype type.

• Removed EntityPrototype::emissions_per_tick, it is replaced by emissions_per_second.
• Removed EnergySourcePrototype::emissions_per_second_per_watt and emissions, they are replaced by emissions_per_minute.
• Removed TilePrototype::ageing, it is replaced by pollution_absorption_per_second.
• Removed ItemPrototype::stackable, primary_place_result_item and can_be_mod_opened, they were replaced by ItemPrototypeFlags "not-stackable", "primary-place-result" and "mod-openable".
• Added "probability" to trigger items and trigger effect items.
• Added "script" trigger effect item. It will call the "on_script_trigger_effect" when triggered.

• Added the prototype type "loader-1x1" that has a fixed belt_distance of 0.
• Changed render layer of belt structures (underground belt, splitter, circuit connector) to object layer. They now have special sorting logic, so they are not rendered over player or cars.
• Horizontal directions of splitter sprites were separated to two sprites (for purposes of the special sorting logic).
• Added AttackParameters::ammo_categories.
• Added optional artillery projectile property "rotatable".
• Scenarios can now contain a description.json file. In the file "order" determines the sorting in the New Game gui; "multiplayer-compatible" determines weather the scenario is shown for multiplayer games.

• Added LuaEquipmentPrototype::attack_parameters read.
