Running this mod with MoWeather I get this error each second when I activate the Time of Day/Sunlight option.

[EvoGui|on_tick:update_gui] Error: [EvoGUI|day_time|update_ui] Error: EvoGUI/value_sensors/day_time.lua:7: Error when running interface functoin MoWeather.getdaytime: moweather/scripts/day-night.lua:32: attempt to index local 'Dat' (a nil value)

I guess you want to call one of this functions:

ModInterface.getdaystart = function(surf) return MoConfig.Surfaces[surf].Time.DayStart end
ModInterface.getdayend = function(surf) return MoConfig.Surfaces[surf].Time.DayEnd end
ModInterface.getdayturn = function(surf) return MoConfig.Surfaces[surf].Time.DayTurn end
ModInterface.daytimeleft = function(surf) return (MoConfig.Surfaces[surf].Time.DayEnd-game.tick)/60 or 0 end
ModInterface.getdaylight = function(surf) return MoConfig.Surfaces[surf].Time.Light end

I think I fixed it (seems to be working for me).

Change line 7 in day_time.lua for this:
function get_day_time(player) return remote.call("MoWeather", "daytimeleft", 1) end

And line 27 for this:
local brightness = math.floor((1 - game.surfaces[1].darkness) * 100)

Edit: No, it doesn't work. There is no error anymore but the time is incorrect and it doesn't update. The brightness is fixed though.

Shouldn't it just be requesting getdaytime for the current surface (i.e., player.surface)? I hope this post is from before the 0.4.104 update, which did exactly that.

Hello I'm loving the mod so far but when I combined it with Moweather I receive this message.

[EvoGui|on_tick:update_gui] Error: [EvoGUI|day_time|update_ui] Error: EvoGUI/value_sensors/day_time.lua:7: Error when running interface functoin MoWeather.getdaytime: moweather/scripts/day-night.lua:33: attempt to index local 'Dat' (a nil value)

I have no idea has to how to code so I came looking for a copy and paste method or new download, but I have the current 0.4.106 version. Keep up the good work, I'm looking forward to using this informative mod.

Okay, I think I see what went wrong now -- @ludsoe sent me the wrong code (or else MoWeather is intended to work this way, but has a bug).

I'll make it work with MoWeather v0.3.90 in EvoGUI v0.4.107, but be aware it may just break again in future.

As a note, the mod portal hasn't sent me any emails to notify me of discussions (it probably doesn't do that yet), and I rarely remember to check. If you want quicker response, I suggest making an issue on Github, posting on the old EvoGUI forum thread, or PMing me on the forums. I get notifications for all of those.

Just noting that this error still seems to happen with moWeather installed when the player walks inside a factorissimo2 factory.

The console spam does turn off though if the time option is turned off, which is simple enough to do when working on factories.
