Thank you!

The characters need players attached …

Two players, two characters? Yes, that really wouldn't help my mod to exchange characters. However, it could be necessary (not sure, must check the code first) for my mod to update the character data (e.g. in games with modded characters, when the player's ...

Oooops, looks like I'll have to rework a major part of miniMAXIme …

I will throw this to Not a bug:

Thank you for your reply! As mentioned in my original post, I wasn't sure myself whether this bug should be classified as implementation or documentation bug. If you say it's working as expected, could you move this to Documentation Improvement Requests instead ...

What?
If you try to set the slot of a constant-combinator to a virtual signal via script, this will error if no quality is provided. According to the description of SignalFilter (used by LuaLogisticSection::set_slot(), which has to be used for constant-combinators), all properties except name are ...

Great news, thank you very much!

Is there a similar mod or can someone fix the script for me?
Error:

Too bad you've left out the actual error message! But after taking a quick glance (without actually trying to run this), it seems all you need to do to get it ...

Moving a LuaCustomChartTag around is easy for players (click on the tag, then on the button next to the trash-can icon), but impossible for mods:

Currently, if we want to move a LuaCustomChartTag, we cannot simply change its position because LuaCustomChartTag::position is a read-only value. Instead ...

if recipe.result then
recipe.result_count = multiplier
elseif recipe.results then
for _, r in pairs(recipe.results) do
if r.name == "firearm_magazine" then
r.amount = multiplier
end
end
end
end


You shouldn't assume that recipe.result_count or r.amount are set to 1, other mods may ...

How do i add my new styles to the existing GUI style instance?

With other prototypes, you'd use something like

local new_proto = table.deepcopy(data.raw[old_type][old_name])
new_proto.name = new_name
...
data:extend({new_proto})


With GUI-styles, this doesn't work. The only style that will ...

[...] It would be very useful to be able to tell which GUI elements are actually currently visible in order to avoid having to update large numbers of invisible elements. [...] For a flow or tab, it would be considered visible if any sub-element is visible.

But what about mods that make frames ...

Is there any chance that the logic will be changed at some point in the future? :-)

I don't know how LuaRenderObjects are handled internally and how much work it would be to rework the logic. But from my – definitely biased, and perhaps naive – point of view, if it really was possible to use the ...

Go to line 1457 in the log I uploaded: the tick number on the left (that is what that is, right?) is identical for many lines. I have checked and rechecked and triple checked for any kind of infinite loop or recursion, and cannot find anything, and certainly nothing that can fire more than once ...

TLDR
Please allow mods to add a LuaRenderObject that is visible both in "game" and in "chart" mode! This would reduce overhead in mods that create renderings visible to all players on a force.

Use case
My mod Autodrive allows players to order vehicles to path and move to a selected position ...

Thanks a lot! Yes, makes sense to set this in recipes, not in whatever the recipes produce.

Is there a way to define a prototype that won't have quality (or will just have quality 'normal'). In my mod Autodrive , I have several BatteryEquipmentPrototypes where quality just doesn't make sense. My equipment (so-called 'sensors') doesn't do anything on its own, it just serves as a kind of ...

When reporting bugs, please always include a game version.

Sorry, may mistake. It was late when I sent this, so I forgot to include the version number. But it happened with version 2.0.55.


I see the return value of the transfer_stack has changed between 2.0.47 and 2.0.55: in 2.0.55 it reports ...

TLDR
It seems LuaItemStack::transfer_stack() will always return true if LuaItemStack::can_set_stack() would succeed – even if no items have been transferred.

The problem:
LuaItemStack::can_set_stack() will succeed if the given stack can be used at all in the given inventory. For example, it ...

I have little programming experience and some essential mods have not been updated for 2.0. How difficult would it be for me to update these mods myself for use?

Thank you, this looks very promising!
