Modding

• Removed utility constants zoom_to_world_can_use_nightvision, zoom_to_world_effect_strength and zoom_to_world_daytime_color_lookup.
• Added SpaceConnectionPrototype::shape.
• Added SpaceConnectionPrototype::origin.
• Added SpaceLocationPrototype::origin.
• Replaced ItemPrototype::fuel_category with ItemPrototype::fuel_categories.

Scripting

Previous changelog: Version 2.1.19

New versions are released as experimental first and later promoted to stable. If you wish to switch to the experimental version on Steam, choose the experimental Beta Participation option under game settings; on the stand-alone version, check Experimental updates under Other settings.

https://lua-api.factorio.com/latest/pro ... otype.html shows me a 404.

not so fast, deploy script is still running and was in the process of updating docs.

[y.petremann]

Added SpaceConnectionPrototype::shape.
Added SpaceConnectionPrototype::origin.
Added SpaceLocationPrototype::origin.

This is not SpaceLocationPrototype::parent, but to what it looks like it seems that it would work the same way

I was trying to make SpaceLocationPrototype able to depend on another location but that adds complexity on factorio side (resolving chains of parent locations and throwing an error if loop is detected) and creates some extra problems for mods if they want to compute position of a space location on map during data stage, so a decision was made that it will be limited to just star map position.

So thats why every mod was broken... (fuel categories)

Oh wow this is why i play experimental here. Quick fix when someone has serious issues like frequent crash. Thank you for your work!

Can you elaborate what it can be used for? I fail to understand what origin does.

[boskid]

For SpaceLocationPrototype, origin sets where center of the orbit is and where distance/orientation puts the planet. For SpaceConnectionPrototype, origin is only used by shape="arc" as a center point. (oh no, i failed to update docs for distance/orientation, it is still referencing the sun)

Basically this permit to have space location orbits not around sun but any place you want
and space connection to be around that place too instead of being placed to match the sun.

Please update the docs to to indicate that setting origin will make distance and orientation to be around that origin, not simply changing orbit
