To clarify my question a bit—what I’m really trying to understand is whether there is any API that allows enabling or disabling an entity’s animation directly, or if there are other commonly used methods to control animations in practice.

At the moment, the only idea I have is to base the entity on ...

Hello. I’m looking for a way to turn a building’s animation on and off through scripting.

For example, I would like the entity to remain in an idle (non-animated) state normally, and then start playing its animation when the player “turns on the power” through a dialogue interaction.

I don’t have ...

Thank you. It seems I was confused.

There is a surface that already exists in save files from previous versions.

I would like to migrate its name to a different one.

Is the surface name not eligible for migration?

I wrote the migration JSON as shown below.

["linox-tile_linox-installation-foundation", "linox-tile_linox-foundation"],

Hello. I am developing a mod called Planet Linox.

In this mod, the order of research is extremely important because completing certain technologies changes the surface terrain, places additional entities, and affects the behavior of various scripts. During normal gameplay, the research tree is ...

I want to create a combinator that represents sine and cosine functions.

Is there a better way to build a machine that performs this kind of circuit processing, other than using the tick event?

And to implement this, do I have to keep track of every combinator entity and run a loop on each tick?

That’s correct. However, in the early stages of development, when I attempted to land on the lava, the landing was successful, and the player was placed in a state where they couldn’t move on the lava.

Could it be that the forced landing being successful was actually a Error?

There’s an issue during the process where the player departs from the spaceship and descends to the planet’s surface. When the player departs and the cargo pod begins to descend, the framerate drops sharply and the game stops progressing.

I’ve been studying the syntax, and it seems that Lua doesn’t have a separate function forward declaration syntax, or it was added only much later. For now, I’ve confirmed that it works when written as shown below.


local on_elevator;

script.on_event(defines.events.on_lua_shortcut, function(event ...

(Before I start my questions, I’d like to mention that I’ve used C, C++, and some basic JavaScript, but I’m new to Lua through this modding project.)

For example, when I register an event handler as shown below, it seems that the handler is not being called.


local test_handler;

script.on_event ...

For example, when selecting a recipe in buildings like assemblers or chemical plants, there are times when I want to produce the same item but simply increase the quality setting.

Currently, when reselecting a recipe, all previous selection states are cleared. If the previous selection state could ...

I’m also wondering if there’s a way to prevent the player from performing other actions while a GUI window is open. Currently, even when the window is displayed, the player can still move their character or open their inventory. Is it possible to make it behave like a modal dialog?

Ah, I solved it. It seems that the direction axis of the flow element needs to be set differently. When I set it to vertical, the horizontally_stretchable property works. Thank you for your answer.

It still doesn’t seem to work. Could the order in which styles are applied have an effect?

Hello. I am designing a dialog box like the one below.

The goal is to right-align the yellow text in this window.

First, I created the text portion of the window using a table, as shown below.

Hello. I’d like to summon a regular Spidertron at a specific location,

and trigger a certain event only when this particular Spidertron is clicked.

Is there any way to distinguish it from other Spidertrons?

I’m trying to make an NPC dialogue window appear when a certain entity is clicked. However, it seems there’s no specific event for entity clicks. Is there any good way to achieve this?

It seems that players who are not connected don’t have a character, so I’m not sure how to control their position and surface for when they later connect.

I understand now — I was asking for something that obviously wouldn’t be included in the documentation. That was my mistake! Thank you very much for taking the time to explain it in detail.
