The "algorithm" for making a rasterized circle is following: choose radius (r) value x,y,r are connected by the following equation x^2+y^2=r^2 loop through possible x values, calculate the corresponding y do something you want to do with those coordinates --generate table of circle coordin...

That's game gui stuff.
Only devs have access to that.

There are already a couple of mods with artillery, if they don't satisfy your own vision, you can peek into them to learn, how is it done. https://mods.factorio.com/mods/Buhamut/Artillery https://mods.factorio.com/mods/sore68/Additional-Turret Also, this thread https://forums.factorio.com/viewtopic....

The scrolling in terrain editor is slow even without map generation.
If you try to make anything bigger than 100x100 map, say a 1000 long straight, the maximum zoom does not suffice. And the absence of overview doesn't help with finding a particular position on the map.

I have mixed feelings about that map view, surely it sounds sooo progressive, yet it takes away the feeling of the big world. Right now you are a single human on an alien planet. You can not be everywhere at a same time. So you automate things so that they can go on without you. There's a certain ch...

No you can't make it seamless like it is the vanila gui. You can bind some key to open gui (example) and construct your own window with LuaGui api.

Alternatively you might try to hook it up to a circuit network and have it controlled by signal.

Yuoki Tani did all that in his mod somewhere.
The problem is he never documents what he does. My guess it is added by this mod:

No there's no command for that. I was referring to the fact that you can emulate the turret behavior with quite little computations involved, if the goal is to attack only immobile objects. The entity would not actually be a "turret" from the game engine perspective. Most likely it'd be a ...

By the way, factorio lua does have bitwise operations, albeit they only work with 32 bits. They are implemented as functions from a library, and that involves a function calls, which makes it slower than other fast solutions. shiftContained=(function() local sh=bit32.lshift return function(x,y) loca...

I don't understand what are doing but you are doing it wrong. You just take that long text you think an error is and the last one is the name you need to translate. The fraction of text before the dot in the message gives you the group to which this name belongs in the locale.cfg . No variations, no...

This error is the translation missing. You open the mod folder, open\create folder named "locale", open\create folder named "en" (for english translation), open\create file which name (unimportant itself) ends with ".cfg", find\add "[item-name]" below that add...

LuaJIT is unlikely to give a faithful representation of performance of the pure lua. Not only it is unknown when the jit will kick in but also, there's no guarantee that the fastest compiled version will also be the fastest interpreted one. There's little to no point in fiddling with operations over...

Most question in the modding help board do get answer eventually. The bomber tutorial is a bit old. Newer ones didn't get public yet: https://wiki.factorio.com/User:Gangsir/moddingTutorial https://wiki.factorio.com/User:Adil/Modding_tutorial The former is brief and concise (seems so), the latter is ...

If done correctly, a "turret" that "can only shoot immobile entities" will be in the list of the less performance taxing mods.

Well, I guess I'm done. I did add the chapter about making scenarios, and about migrations and about making mod fast. I myself do not intend to change anything I've already wrote. Something might be added to the middle chapter, which deals with various modding tricks but, as some great person said: ...

Yes, it must be done through script.
A true turret entity from the game will only care if its enemy or friend.
You'll need to use lua to perform all the turret logic.
It's not like it will be problematic though: buildings are immobile and don't appear out of nowhere.

Pathfinder would be useful indeed.

This is editor, you know, if there is no tiles, then that does not mean there won't be. And is it difficult to shave out of the map tiles at the moment of saving the map? I've run into this bug when trying to shrink the area actually. There is no indication of what's happening whatsoever so I've eve...

I'll just leave a mod here.

I know of no way of writing a localized string value into a file. But the locale files themselves are exactly what you are asking for, except on per-mod basis.
