I can't seem to be able to reproduce the state that the spiderling was in though. Just creating a spidertron with https://mods.factorio.com/mod/realism_spidertron and then removing the mod isn't enough to trigger a crash.

To reproduce, load the attached save with the mods Editor Extensions, Spidertron Patrols, but NOT Exotic Industries. Click on the spiderling and it will crash. The spiderling was created whilst Exotic Industries was active instead of K2, so it used to require fuel. 31.660 Error CrashHandler.cpp:635:...

You can copy and alter mods as much as you like, as long as you don't share those copies/alterations with anyone else. If you do want to distribute them, then you have to check the licences of the mods that you copied.

Not sure how feasible this would be - spidertrons do wacky stuff at high speeds (viewtopic.php?p=569165#p569165).

What's the functional differences between this and Editor Extensions? Creative Mod(e) has its own independent interface, tools, and even has its own section in the player's build menu. Like this? ;) https://raw.githubusercontent.com/raiguard/EditorExtensions/master/screenshots/testing-tools.png

You don't need a mod for this. Simple backup software can do this. There are four autosave files? Why do I need to know that? I want to load the last good gamesave and nothing more. The autosaves aren't just for corrupt saves. If I make a mistake in game and don't realise for 10 minutes, I might ch...

Pretty sure that register_on_entity_destroyed + on_entity_destroyed is the way to go here.

If you just want to be able to remove landfill, try https://mods.factorio.com/mod/simple_landfill_mining. It will restore the water tile to exactly what it was before, but only if you'd placed the landfill after installing the mod (since otherwise, the game had deleted the information).

https://lua-api.factorio.com/latest/Concepts.html#LuaSectorScannedEventFilter makes no sense. Presumably it allows me to filter the name of the radar that did the scan, but most of the wording and listed things seem completely irrelevant. -> Yup you're right. Unfortunately, the internal system to do...

Not sure about the 0 vs 00 thing, but you should have just gone to 4.1.10 - software versions are not decimal numbers, they are 3 separate integers separated by dots. 4.1.9 -> 4.1.10 is completely standard, and is how factorio itself does it (1.1.9 -> 1.1.10).

I finally found the time to do this as a mod . It works perfectly for on_player_mined_entity and on_robot_mined_entity. However for script_raised_destroy it's not so clear what to do. I have decided to spill the item on the ground. I've added a related modding request at https://forums.factorio.com...

I'm able to get width by putting text into a `.gui.screen` label, call `.force_auto_center()`, wait a tick, get `.location.x` on the frame, then do some math. Since GUI elements are specifically per player, I'd assume that avoids the desync issue. The desync problem is that now you have access to a...

Belt interactions for characters, units, and cars can be disabled on the prototype using `has_belt_immunity` but not spidertrons (or spider legs...). This would be quite useful, see https://mods.factorio.com/mod/lex-aircr ... ec7600e31c.

Why even make a version for Mac if something as basic as Esc does not work? I mean yes, there may be workarounds that suffice after experimentation but then what is the purpose of making the game specifically for Mac? I'd almost rather use a virtual machine with Windows but then that would have onl...

To reproduce, load the attached mod (and enable its dependencies), and start a new game. Commenting out `check_buildability = true` in prototypes/lava-pool.lua prevents the crash from occurring.

It sounds like might be confusing data and control stages. Your first bit of code is data stage, and your second goes in control. Read https://lua-api.factorio.com/latest/Data-Lifecycle.html if you are unsure. If that wasn't your problem, then this probably was: newly created items don't get a grid ...

Moving the camera position is basically impossible. Cutscenes is one option, maybe there's some other hacky solution I hadn't considered... A larger problem is that you can't read the player's cursor position. Or at least, you can, but only in response to a CustomInput (i.e. when the player clicks o...

Picker dollies and Space Exploration both use teleportation and are both very common. It would be nice not to have to rely on implementing custom events, etc.
