I suspect its an order-of-operations issue, in that built-in logic hasn't recomputed that the inserter drops into the just-built container entity. This seems likely. I don't know when it gets set; maybe in the next tick, maybe whenever the inserter is next updated, maybe the next time the inserter ...

The thing is that Factorio isn't about good quality graphics to most players. Most of the game is spent plopping down blueprints in map mode where there are virtually no graphics at all, just color blocks. This is a horrible sweeping generalisation. You're free to play with your coloured blocks, bu...

LuaSurface.create_entity can create beams and streams. The notes below the main doc for each of the additional per-entity-type properties say that both of them can have target_position , source_position , and source_offset . You still have to set position because it's mandatory (even if you've set ...

Spider vehicle movement is based on how their legs move. If you want something that looks like a non-spider hovering vehicle, you give it one invisible leg. The top speed of a spider vehicle is essentially hard-coded, because there is no direct way of setting the maximum speed of a leg in the protot...

Thanks, that works.

Spider vehicle graphics sets define four Animations for the positions that constitute their autopilot queue and final destination in world view and map view. If you want them to be disabled, you can leave them as nil and nothing is drawn. Simples. There are also two line width properties for the con...

+1 Relative GUIs can't drag the frame they are attached to because "the element needs to be a child of the drag_target at some level" and "only top-level elements in LuaGui::screen can be drag_targets". Relative GUIs aren't a child of gui.screen at all so they can't drag themselv...

For mod settings, string settings can have a localised string tooltip for each drop-down string. This appears when the drop-down is dropped down and the individual item is moused-over. However GUI drop-downs don't support anything similar. The drop-down type of LuaGuiElement specifies a list of item...

In car type vehicles, you can set a rotate boolean property to true inside the WaterReflectionDefinition, and the water reflection sprite will be perspective-rotated according to the orientation of the entity. For spider vehicles, SpiderVehiclePrototype.graphics_set.water_reflection.rotate does not ...

Since I have played Industrial Revolution , I treated its sub-mod Deadlock's Research Notifications as a must-have : https://assets-mod.factorio.com/assets/215b1567c19d55284e0c0a814891c9aa9e0dfc4e.png So I am glad that its functionality has been integrated in the base game ! :D Mine was prettier. M...

If the visualisation is independent of existing entities in the world, you could use the radius visualisation specification . It's not - like a ug pipe, the drawing needs to happen when two entities are facing each other. What about can_build_from_cursor - if I can't get the cursor ghost direction ...

I'm not against that idea. However currently setting selectable_in_game = false does not prevent an entity from being deconstructed. It also does not prevent it from colliding with other entities or from being built by the player. I didn't say that it did. I don't mind what goes into the cake, I ju...

I'm trying to recreate something similar to the "underground visualisation" you get with underground pipes: Untitled.jpg The entity ghost concerned, though, can't be an underground pipe (for reasons). It is either a crafting machine or a SimpleEntity. So I would have to be able to know whe...

A different way to handle this would be a new property at the EntityWithHealth level, very similar to the existing integration_patch and integration_patch_render_layer properties, i.e. a Sprite4Way. Functionally they would behave exactly the same as integration_patch except that the sprite-per-direc...

If you mean a 1x1 tile, then it's going to be even more desirable to have a property/flag that hides the red "colliding" selection box, or have selectable_in_game make it go away as well. It would break hacks like this one which currently only shows the tiny red cross, I was planning on us...

Selection boxes have a few ways they can be influenced. The default for selection_box is documented as {{0, 0}, {0, 0}}, which has zero area and is described as "empty". Empty selection boxes can't be moused-over and therefore the entity is unselectable. Furthermore, if selectable_in_game ...

In the same time/effort/bug-saving spirit as this request . It would be very useful to have a way of giving entities that use Sprite or Animation (or arrays/structs of same) a way of displaying custom alt-mode info without having to resort to the rendering API (not currently intended for large-scale...

https://lua-api.factorio.com/latest/prototypes/SimpleEntityWithOwnerPrototype.html For SEWO and SEWF, the picture property is listed as type Sprite. But the old wiki lists it as a Sprite4Way and the game appears to treat it like a Sprite4Way, i.e. directions do work. They inherit from SimpleEntity w...

Current SEWO/Ps have a picture property which is a Sprite4Way, allowing you to give different sprites to the entity depending on which direction it is facing, but these can only be static sprites. There is also a pictures property which allows for multiple variants of sprite (either random on creati...
