fluidbox = nil if not fluidbox == nil then evaluates to if not true then which evalautes to if false then And since it is false goes to the else part That's not what happens. According to operator precedence , "not" has higher priority than "==". So in this expression not fluidb...

Operator precedence.

Have a look at data/base/prototypes/item/item.lua. "diesel-locomotive" got renamed to just "locomotive".

Oh, so the problem is not how it is deregistered, but when it is registered? Say, if I register on_tick only inside on_built_entity, the game will desync when another player join the game because on_tick is not registered for him? That's why you also check in on_load whether there's stuff to do for...

Spaces in file names work fine if they are properly quoted or escaped. You just need to pass the actual file name instead of some gibberish.

I think it's only bad if you do it unconditionally. This would break multiplayer as the on_tick handler would run once for the player who just joined but not anyone else.

Okay, just read your first post again. 0.001 Program arguments: "factorio.exe" "--start-server" "C:\Users\Adam\AppData\Roaming\Factorio\saves\ MP.zip" "--server-settings" "server-settings.json set ServerSettingsLocation=D:\Steam\SteamApps\common\Factorio\...

I think the "noise effect" in mapview-zoom is way to low now. can i change it somewhere? I often take the mapview for normal and forget to leave it. Would be nice if i could change it to a little bit more. In data/core/graphics/shaders/zoom-to-world.glsl, multiply the return value of getn...

"game_password": test",

Now there's a double quote missing...

Put a comma after the closing curly brace of the "visibility" block.

Yes, it's been overloaded since the 0.15 update. It's still somewhat usable from time to time.

There. A bit rushed, but should be usable again. Current release doesn't know about the increased underground belt length of the recent update yet (that really had to be released today, just when I thought I was done with porting the mod?), making this configurable will take a little more work.

I'm a bit short on time at the moment. Looks like a few minor things need to get done besides changing "factorio_version" to "0.15". Should manage to get a release out tomorrow I think.

Access to the data table is only available during the data loading stage, see Data Lifecycle.

You can see how the base game defines fuel values in data/base/prototypes/item/demo-item.lua and item.lua.

During runtime, you can access fuel values via LuaItemPrototype.fuel_value.

LuaControl.clear_items_inside()

If you use next() on the return value of get_chunks(), you really only get the __self = "userdata: ..." thing out of it. The interesting behavior is implemented using metamethods so it can be used in a generic for . You can turn that into a while loop as mentioned in the manual like f, _, ...

It's generally something like data.raw["type"]["name"].the_thing_you_want_to_change = new_value so in your case maybe data.raw["item"]["iron-chest"].icon = "__newicons__/graphics/icons/iron-chest.png" to do it one by one, or if you have replacement g...

Time for a bug report.

Are other games working fine?
