The `layers` field should be optional in the prototype Animation.
The example on the page confirms this in addition to my working code.

The `picture` field is listed as mandatory, but it's optional for "basic" type. The `rotation_shift` field is the same requirement concept and is listed as optional.

The docs list a single object/table of fields. But accepts an array of objects as per your included example.

The definition of the resistances field in EntityWithHealthPrototype is the type of Resistances. But looking at this Resistances class its a single object/table, rather than supporting an array of Resistances. I'm not entirely sure on what the valid options are the, but the example array of tables i...

It seems that if a unit is created in a map and the game saved. Then the unit prototype's speed is changed in the mod. When the game is loaded the existing units keep the old prototype speed, with any newly placed units getting the new prototype speed. See demo video, save and sample mod attached. I...

The Prototype MinableProperties class has some optional fields not marked as such: required_fluid & mining_trigger https://lua-api.factorio.com/latest/types/MinableProperties.html I quickly checked and these are correctly marked as optional on the Runtime side. https://lua-api.factorio.com/lates...

It does look much more inviting for new-to-mod users. As your presented with groupings of good mods, not just a mash of latest mods. With half often having been: WIP, alpha, personal, etc.

Seeing `fresh mods of the last month` category, I would like to be able to expand it and see more than just 5.

I looked at that topics opening posts before making this thread. But it looked to be a much larger and all encompassing geature ask, than this simple gui addition for existing functionality

It would be nice if there was an in-game GUI to manage what alerts and warnings are shown to the player. Rather than having to use console commands.

I appreciate these are per map and not global, so would be like the map overlay toggles.

The Factorio Version Selector dropdown has bad styling. I tried forcing a clean reload and still happening.

Another user has confirmed they see the same issue.

Do you count continuous max pathfinder UPS for a few unit groups to get through many layers of walls as a performance issue ? It only becomes an organic issue on very large bases, but can easily cause the pathfinder to stay at its max processing indefinitely. Save that shows the pathfinder strugglin...

If you change some pathfinder settings while the game is doing a pathfind it will desync. Encountered in an MP game, but reproduced in SP with heavy mode enabled. This was encountered in an MP game as we had a long queue of path requests due to many layers of wall around the base and artillery trigg...

When 2 cars are created on top of each other and the player is driving one of them things go a bit odd when trying to leave. I appreciate this is an odd situation, but encountered when modding and swapping a vehicle a player was in for another one and wanting to eject the player during this process....

The LuaEntity.set_driver() and LuaEntity.set_passenger() both list the parameter as mandatory in its type, but in description it lists the valid use of nil . Noticed as Sumneko flags the discrepency. https://lua-api.factorio.com/latest/LuaEntity.html#LuaEntity.set_driver -> Good catch, thanks. Fixe...

When you have a border between 2 different land tile types and then place a single tile of water just inside this border the water tiles edge graphics goes odd.

Save with issue demonstrated:

The properaty_names argument that LuaSurface.calculate_tile_properties() takes is a little sparse on what property names it actually takes. The example is height , but doing a search in the API docs of height didn't return an obvious list of the property strings I could provide it. https://lua-api....

The Factorio wiki description on an EnergySource for the Electric Energy Source is a bit misleading. When flagged in a discord chat Bilka requested it was raised here as a reminder for future clarification. https://wiki.factorio.com/Types/EnergySource#buffer_capacity Area of concen: Shouldn't drain...

LuaEntity.damage() says that the type and dealer are optional. However, if you actually provide nil to either of these you get an error. They are optional in the sense that you don't have to provide those arguments. This means to provide a dealer argument value you have to provide a type argument v...

At present there isn't a way via the API to check on the amount of fluid needed in a fluid-turret for it to activate. I wanted to do this as a check during an RCON command by Streamers to create and fill up fluid-turrets. To alert them if they were putting in less fluid than the turret required to a...

If you create a fire with the max initial_ground_flame_count of 255, the fire doesn't burn like the a high fire count should. This can be seen by creating a fire at 255 and at 254 (1 less). The 254 fire spreads out from the center for a bit and will catch any near by trees on fire. But the 255 value...
