0.17.29

Date: 12.04.2019

Changes

• Simplified rail building. Holding shift while rail building always activates the combination of ghost-rail-building + remove-obstacles, releasing shift returns back to normal manual mode. It doesn't matter anymore, whether the rail building started with shift or not. This removed the possibility to do ghost-rail-building without the remove-obstacles, but since it seems to be almost useless, we consider it to be worth the simplification.

  • They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
• Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.

• If building of entity/blueprint fails, the reason of it is pinged as flying text.

• Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
  • For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
  • Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
• Blueprint/special item tags.
  • Shift clicking the icon in chat will create an item and place it in the cursor.
  • Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
  • These tags also work with deconstruction and upgrade planners.
• Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.

• Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
