That's understandable, i thought since upgrade planner had the restriction, fast replacing had it too

Its... weird. It allows fast replacing assemblers that'd collide when placing a foundry, but not when placing an oil refinery.
This is with a mod that just does this:

for type, _ in pairs(defines.prototypes.entity) do
for _, prototype in pairs(data.raw[type] or {}) do
prototype.fast_replaceable ...

- Install https://mods.factorio.com/mod/Tiny_Solar (version 1.0.8)
- /cheat all
- Place a 3x3 grid of tiny solar panels изображение.png
- Force build (ctrl + shift + click) a regular solar panel in the middle изображение.png
- When a robot builds it, the solar panel now overlaps the 8 tiny solar ...

Thanks. For autoplace_settings, i was just curious/evaluating the options i had, if its complicated i'd need to test it anyway, no need to dig deep into it.

Is it possible to get a flag on LuaRenderObjects to enable some sort of anti-aliasing?
Sprites and animations do it (unless SpriteFlags on SpritePrototype change it), but can geometric shapes get it too?
Circles espeically look ugly at low zoom levels

https://lua-api.factorio.com/latest/concepts/MapGenSettings.html doesn't list any property as optional, however you can create a surface with an empty MapGenSettings /c game.create_surface("some-surface", {})
As such, all properties should be marked as optional. It'd also be good to specify what ...

Pollution trigger effect will be added in 2.1 viewtopic.php?p=687450
But right now you can use script trigger effects as said above.

Download and unzip the mod into the mods folder:
Load the save file:
Game crashes: If needed, i can later try narrowing down what changes in the mod causes the issue.

Oh right, it doesn't control drawing it in inventories. Sorry for the confusion

Can there also be one for ammo bar? For items whose main purpose isn't being ammo.
Or would that not be a thing similar to science packs?

collision-mask-util.lua in core/lualib uses collision-mask-default.lua to use as default. collision-mask-default.lua returns a constant table. While this doesn't allow mods to change the default, this is fine.

However, there also exists a utility constant default_collision_masks . The two are ...

Make a transport belt yield a different item:

Also remove the transport belt recipe:

Most (if not all) licenses mods use allow you to edit files locally. But also, you can ask the author to remove the incompatibility, and often they'll change it. An incompatibility can be replaced with a custom error message at data or settings stage that other mods could disable.

This is the same request as viewtopic.php?p=671080 (and i +1 it anyway)

This is a bug that will be fixed in 2.1 viewtopic.php?p=685853

The game prompts you to sync mods with a save file if you don't have a mod enabled that is enabled in the save. So if you make a save, you can later restore the exact mods you used.

Sliders can accept an arbitrary minimum an maximum value, as well as a "step" value (how much is each notch). So yes.

- Define a recipe like this

data.extend{
{
type = "recipe",
name = "spidertrons",
ingredients = {
{type = "item", name = "spidertron", amount = 4},
},
results = {
{type = "item", name = "iron-plate", amount = 4},
},
}
}

- Place an assembler with that recipe
- Put one spidertron into ...
