Why ? For Dana , I need precise control of the size/position/x-y ratio of sprites in rendering.draw_sprite(). For some kind of sprites (ex: technology, entities) which don't have standard dimensions like item sprites, this doesn't seem possible with the current API. Proposition 1) New read-only cla...

Is it possible to build some dll and call the functions from __my_mod__? As mentioned by others, you can't have the Factorio process load any DLL you provide and start calling its functions from your Lua code (And from a security point of view, I hope it never happens). That being said, if I take y...

If a recursive localized string does not make sense, why do you try to create one? Because I wondered what the game would do in this situation. Since your question has a strong implicit smell of "Then this bug report is useless. Nothing to fix, just stop doing that", I'll add a little som...

What happened Attempting to print a recursive LocalisedString via command line causes a hard crash (stack overflow). Steps to reproduce Start a new game Type the following command: /c local str = {""} str[2] = str game.print(str) Logfile attached. Expected behaviour A recursive LocalisedS...

Just for context, I initially dropped in this thread because from my initial understanding, what you were trying to achieve could have required some graph rendering/interaction in a Factorio mod, and I happen to be working on that (for a complelety different usage though). But since you've decided t...

I might have missed something, but I don't understand what you're trying to achieve or how it's related to Factorio (and the 1st answer to this thread seems to indicate I'm not the only one). What are you trying to deliver ? A standalone mod working out of the box (just download from the game portal...

From my point of view you're refusing to talk about solutions for clear() because they don't also fix modify. You can rest assured, my next major release will have no problem handling gui.center.clear(). I also plan to handle on_gui_closed. I know that clear() happens (*cough*), but as far as i can...

Oh, and i can make it crash with rendering.clear(), suprise! I stand unsurprised. I was caught off-guard by the possibility of cross-mod GUI modification, but was fully aware of the potential rendering issues. I can think of dozens of way to make my mod bug/crash through commands or other mods, and...

Thanks for the answer. Personally I don't mind the issue to not be really fixed. I just want to generate a pseudo-recipe: boiler X takes fluid A as input, outputs fluids B, and uses fluid C as fuel (with possibly "any fluid" if there are no filters on the fluidbox). If you have any suggest...

But @OPs Dana doesn't react to on_gui_closed. Which btw is documented as "This is only called if the player explicitly closed the GUI." Soo... still arguing against windmills. And that's something I'm willing to change if there is any need (if I get to understand what it does, because the...

No. A shared resource can be arbitarily altered without my knowledge or consent. I am forced to share it with people i don't even know. That's exactly what GUI is I agree Factorio indeed expose mod GUIs as a shared resource. I think we'll also agree that in practice, no mod really support arbitrary...

Manipulating the *inside* of other mods guis is ofc broken. TL;DR: The easiest method to deal with it is to properly check existance and .valid before you try to use a shared resource (gui, rendering, inventory, etc). If you trully consider the GUIs as a shared resource, then it heavily contradicts...

First mod was Informatron, which should be fixed from v0.1.12
Second mod is Space Exploration.

I doubt any mod author would do such things on purpose. Well, the mod author I contacted has a different point of view: If any mods are broken by a player.gui.center.clear() call then those mods should be updated to handle that situation. When a mod uses the center GUI is it usually to take the mai...

Excellent, I've found another mod doing the same thing. The joy is real. For example, running clear() on one of the root GUIs is obviously a no-go. If a mod is doing that, then people can simply not use that mod until it's fixed. The issue is about finding "that mod". If it takes multiple ...

No need to shame anybody, the other mod got an update today addressing the issue. Though after looking at the code the "gui.center.clear()" just moved into a if-then statement, so I'm not sure I'll be sleeping very well in the near future. My original question still stands: how to detect/p...

Hi, after hours of investigating a bug report of my mod, I discovered something unexpected: other mods can destroy LuaGuiElement(s) of my mod. While I could understand that in some situations, it might be convenient for mod A to modify the GUI of mod B, in my situation this is totally unwanted &...

LuaGameScript.write_file() has a 3rd argument named append:
Setting it to true should solve your problem.

Description I am using the API to get the index of the LuaFluidBoxPrototype used as fuel input in a LuaEntityPrototype (more precisely a boiler prototype). I do it like this: local index = entity_prototype.fluid_energy_source_prototype.fluid_box.index However it does not match the right fluidbox in...

Hi, I'm just dropping here out of curiosity as someone who started modding quite recently (I don't currently have any need of changes in the data stage, but I can understand that others have). Given that modders don't even use the 3 data stages properly, I don't see how a more complex system could w...
