Hi there, I have a small GUI problem I would like to adress. It concerns scroll-panes, and I want the scrollbar (if it is visible) to always be as right in it's 'container' as it can be. The property 'horizontally_stretchable' on the scroll-pane seems to do this just fine, but I found that it screws...

Alright, after several hours of trying to get this to work, I'm ready to move on. It has to be possible somehow, but it seems I'm not going to find out how for the moment. Thanks everyone for their help, though! Now, onwards to trying closure-based objects. Edit: Well, seems like that approach has k...

No, they are not. I just need them to get reapplied on load to my classes. Just loading the file definition normally doesn't work when loading a save, I assume because then you recreate the classes, and the data you already saved has technically been saved with a different 'class' (different unique ...

Yes, see doc-html/Data-Lifecycle.html in your install or at lua-api.factorio.com/latest. I read that, just wasn't 100% sure if I understood it correctly, thanks for confirming though. Another thing I just noticed in my testing, is that when I save the class (BaseClass for example) into the factorio...

edit 2: see my edit of the original code, fixed Yeah I thought of namespace conflicts as well, should have tested that I guess. Fixing it prevents the crash, but sadly still doesn't have the intended effect. Thanks for your suggestions though, they made me understand the problem at hand much better...

I haven't tested this, but I believe it'll work. Alright so I integrated this, and on world generation, it works, but when loading a save, the two lines in on_load() lead to a stack overflow for some reason. In the error report it says the overflow happens on the setmetatable(table,meta) call, insi...

Thanks for the reply. I already store my objects in a global table. The issue I have, it seems, is with restoring the metatables correctly. How can I achieve that? Edit: The error I get, only when it is a loaded save, is that the functions of the class can not be found(= is nil). So I assume the met...

I've been trying out classes in lua, including inheritance. My code looks like this: BaseClass = {} BaseClass.__index = BaseClass setmetatable(BaseClass, { __call = function (cls, ...) local self = setmetatable({}, cls) self:_init(...) return self end, }) function BaseClass:_init(name) self.name = n...

As a side note, on_load() should only be called in very specific instances, otehrwise it leads to desync. Also, you can't use game.print() in the on_init() function, because on_init() is called before the world is fully loaded.

Thanks, especially for your answer to my second question. I overlooked that property.

No problem! I have given your first question some thought, and I might need something like that soon in a project I'm working on, so if I come up with anything, I will let you know.

A few more: 1. Is it possible to make an entire row in a table clickable? Ideally, the row should be highlighted on mouseover. There is a table_with_selection style, but it doesn't actually allow any kind of selection. 2. Alternatively, is it possible to register clicks / mouseover through GuiEleme...

I assume you want to put an exit-button in the top right corner. Well you can get around the frame issue, by simply not settings a title, and doing it yourself, like this: local main_dialog = player.gui.center.add{type="frame", name="main_dialog", direction="vertical"} ...

Being able to do this without explicit user input is kinda risky, as it can lead to data loss. You can overwrite anything the user has in his clipboard, which could be something important. Sure it won't be the case very often, but the potential is there.

You can use this function:

Oh wow, would not have thought to check the GUI class, even though it seems kinda obvious. Thanks a lot!

Hi, sorry to dig this up, but I have a problem that this would also solve. I'm working on a GUI-mod, and it displays item-sprites that the user can choose. Now if you add a modded one, and then remove that mod, I can no longer display it obviously. I would like to display a default image instead. No...

You don't want to ever catch an error unless it's something outside of your control (parsing user input for example). Catching errors in your logic just means you'll never hear about it being broken. If you have it crash-to-main-menu people are far more likely to tell you if they ever have an error...

Yeah I totally agree that in multi-line ones, enter should go to the next line. Implementing a shift-enter or ctrl-enter would be nice, but not as important, as those multi-line boxes aren't used for some quick input typically, thus aren't used as frequently, which makes enter not working less annoy...

I noticed that, when defining styles in the data stage, we can use the attribute padding to easily define all 4 padding-attributes (top, right, bottom, left) to the same value, at the same time. In the control stage however, this attribute is no longer available, and you have to 'manually' set all 4...

I'm currently working on an all-GUI mod, and I would love it if any errors that it produces would not crash the save. For development, crashing is fine of course, but when other people use my mod, I would feel better if they wouldn't lose unsaved progess on their game because of some error on my par...

the deeper you go down the chain usualy the ore/plate gets better Yes it does, and that is great, but I feel the additional effort is not worth it. Having to plonk down 180 machines and using 100MW of power seems worse than plopping down more miners to get the 4000 additional ore and having to expa...
