Thanks for confirming! I am willing to send you my code if I get desperate, but let me troubleshoot more before I burn more of your time. :)

I was already thinking this was a PEBKAC error on my part, and just wanted to rule out that there was some subtle API misunderstanding I had. Your replies ...

play_sound() calls can not play the sound if it would play with 0 volume due to it being played too far from the listener, if the sound position is covered by fog of war

Makes sense. But in this case I'm using luaForce.play_sound() with a nil PlaySoundSpecification.position thus I believe it's ...

Hi,

I have a mod that (conditionally) uses luaForce.play_sound(...) in a on_entity_died event handler. Despite my best efforts and tracing through with a debugger, I'm finding that the sound does not reliably play despite the function call for sure executing.

Is there any circumstance where play ...

Ah, makes sense. Still, if you could comment with example types of things that needed to be "rolled back" via a custom mechanism for a mod, we could try to start making a list of things that would need to have a solution. IDK. Just a thought.

Hi folks,

Thank you for the interest, discussion, and suggestions!

The more I think I’m about an uninstall script the more I am convinced that - while it would represent a lot of flexibility - it does not make sense architecturally. I also think that it sets up uninstalls to nearly “always fail ...

Another example situation I just hit right now when writing a mod. In my mod, I did this:

player.mute_alert(defines.alert_type.entity_destroyed)

I load a save with my mod. Save game. Then I disable mod. File no longer plays alerts anymore even with mod removed.

It would be great if Factorio ...

Something I realized after posting this is that while I like the general concept of being able to attach a 'mod owner' to global state objects like luaForce, cleanup does get a bit complicated if you have a structure where one force is defined as collapsing into another when the mod goes away, but ...

Hey,

This is only a half-formed request, but interested in what people might think -

I don't do much modding, but I did publish a mod back in the 1.0/1.1 days, and thinking about resurrecting it for 2.0, now. It was a semi-evil mod that made force changes in order to accomplish prioritization of ...

Hey,

So for years I've wanted this functionality as well (to set up remote outposts that auto-request delivery of missing requests). I've used Ghost Scanner at various times in small networks when the performance impacts were acceptable (many to the original author of Ghost Scanner and all those ...

Got it! Thanks. I think I wasn't properly interpreting the description of the 'type' property which is what confused me initially.

Hi @Xorimuth,

Thank you for your helpful and insightful commentary.




I don't think pairs() will work for what you want either, using pairs() on a LuaObject will not iterate through all valid properties, it will generally do nothing. (I think for some things, it can be used, like for a ...

Update - ahh, yes, now I remember why I started down this path. It's because attempting to access a property that doesn't apply to an entity will trigger an exception rather than returning nil. THAT'S why I was trying to detect the type proactively and only THEN read properties I knew would exist ...

Got it, thanks for the help!

I get the sense that you might be assuming that the Factorio prototype system is a lot more "object oriented" than it really is, which could be why you're struggling. A prototype in Factorio is really more just a clump of data telling the game engine what it is. On the C++ side, there's a whole ...

Gotcha. So in the case where a mod is extending an existing prototype, checking .type (instead of .name) would return the same Lua *Prototype class of the 'base' object despite it potentially having a different prototype name due to deepcopy+extend? Is that it? Or is it possible to modify .type when ...

Sorry. Bit of a concept question here, definitely of the 'noob' variety -

So, despite having written a mod for Factorio I still struggle a lot with the concept of prototypes in the game and what that actually "means" (my mod didn't deal with too much custom prototype stuff, etc. hence why I think ...

"Ghost Scanner"
"Logistics Signals"

were two that I used.

First off, I LOVE what you're doing with the expansion. Secondly, I LOVE your latest series of FFF.

None of the following criticisms are intended to detract from either of these. :lol:

I was super excited to see the wireless signal transmission feature of the Radars until I read this:

So we ...

Hello,

I really found the "Data Lifecycle" documentation page very helpful when I was reading it the other day struggling to remember how the various initialization-related events worked. It's great, but there were a few outstanding questions in my mind after reading it.


#1. I had a question ...

Super helpful, thank you!

@boskid if it's all right with you I might try to distill your detailed answer into a small set of enhancements to be added to the Data Lifecycle documentation page.
