Good point. This is really handy for anything spage-related.

There are many mods that want to use spage assets without relying on spage, which then requires feature flags + duplicating assets.

It would be cleaner to tell factorio: “Please make spage files available for me to draw from, regardless ...

Context

Sometimes, when modding, I would like to depend on X mod to have factorio use that mod’s assets or libraries. However:
1) Some mods are stuck in 1.1
2) Many mods normally come with code that I don’t want executed. Data stage stuff can be reverted (with great effort) while many things can ...

Actually I disagree here, I feel like this could be abused a lot to enforce specific playstyles or


Consider: The alternative is running the exact same code in control stage. I can’t stress this enough:
Data stage tasks do not belong in control stage

This data stage ...

If the interest in actually doing this is real, and not trolling, here is how I would request the implementation look like with an example. Imagine the mod "Rubia" wants to define a "wind restriction" data object, to define how control-stage scripts should operate on a given entity.

Rubia's data ...

+1

If devs want to send new types of data from data stage to control stage, they can add a new prototype type. eg Any prototype with only 1-2 fields is simialr to passing yourself a hashset/dictionary from data to control stage. Modders do not have this option.

As Osmo said, we can already smuggle ...

Yes. Sorry about that, Lou.

This wind turbine is "electric-energy-interface" with gui_mode = "none" by default.

Bug #1) ElectricEnergyInterface.gui_mode = "none" gives no simulation, while a window still opens.
Expectation: "none" => no window at all OR window with just a simulation.

Bug #2 ...

TL;DR Shields regenerate a large fixed amount for 1 tick if you took damage while at max shields

This may be obnoxious to fix. I have had my suspicions that it is slightly off for a while, and this code confirmed it. It looks like the bug where shields get a very large regen boost for exactly 1 ...

Factorio Mods are completely open source Lua Scripts in a ZIP file - there is no way to apply DRM or code protections, just simple obfuscation.

This is false. Your rights over your own work have all rights reserved unless YOU explicitly give them away. The terms that you cited only give Wube ...

Thanks, Genhis! I appreciate the work you do.

FYI I have reached out to a few mod creators who have hidden techs in their mods. They should be prepared/preparing for this change.

Thank you so much for both addressing and building on my bug report!

My Problem
My mod needs to execute code whenever another mod changed the pickup/drop positions of an inserter. Specifically, I am making a surface where inserter pickup/dropoff positions have a certain restriction to them. I would like to have compatibility with adjustable inserter mods.

I was also planning to do something like this, but doing all the machine entity swapping shenaniganery made it much less attractive.

Thanks! I appreciate it.

Even if it isn’t exactly what I wanted for my use case, I can at least now detect it on_gui_close and on_gui_checked_state_changed, change it back, play error SFX, and print an error telling the player that they can’t do that. This should be more than enough for me to do my ...
