Got it. In that case, I'll lower the entity's maximum health for now and then see if checking its health more frequently causes any performance issues. Thanks for your help!

I'm trying to deal 1 point of damage to an entity with 100 million health. The hit seems to register, but the entity's actual health doesn't appear to decrease.

I'm not sure what the exact conditions are, but sometimes the vertical scrollbar disappears when the server profile becomes very long due to the number of installed mods.

As far as I can tell, this isn't limited to a specific version and appears to be a fairly old bug.

At the moment, enabling the "Has mods" filter also includes servers that are only using DLC content.

Personally, I think DLC content should probably be excluded from this filter. In practice, the main reason people use the "Has mods" filter is to find servers running ...

When generating a map with mods, adjusting the frequency, size, and richness of every resource individually becomes quite tedious. It would be great to have a global adjustment feature that lets you change them all at once.

Hello,

I'm currently updating Planet Linox for Factorio 2.1.

While working on it, I discovered that players can reset a power pole's wire connections by Shift + Left-clicking on it.

The problem is that Planet Linox uses special power poles to connect the surface and underground surfaces. Players ...

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.

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.

(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.

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?
