What is game.player.opened [done]

[matjojo]

I am working on the new version of Equivalent Exchange(EE2), I need to make a GUI when an entity(container) is opened, I found the mod Galactic Trade which does this but could not figure out how he/she does it.
Is there some Function like game.on_init to use when wanting to achieve the discussed result?

Or is there another thing I could do?

As usual I'm open for giving extra information.

The only way I can think of is to check player.opened every tick/few ticks and do things whenever it changes.

well, thanks al lot, I didn't even think of searching this on the player side of things, I'll report back oncy I have something more to say other than thanks!

So yeah, although the idea you had probably will work I am failing at another piece now, it probably is something really small but my code:

Code: Select all

require("util")
require("defines")

--the code
game.on_event(defines.events.on_tick, function(event)
if game.player.opened == "energycondenser" then
	EEisopened(1)
end
end)

function EEisopened (a)
game.player.gui.testframe.caption = "Game detected the opening of the Energy Condenser"

end

Does not work, It give this error:

'5' attempt to index global 'game' A nill value

Now line 5 is the line which has game.on_event(defines.events.on_tick, function(event) on it. But, I copied this line straight outta( ) Galactic trade 0.6.4 beacuse for the Gui thing I already had downloaded that mod. But still, The code didn't work. Even if I copy the line exactly. What am I missing?

I will be trying to delete pieces of the galactic trade mod to see which part of the code makes this work. but as always I'm open for more info.

Are you maybe doing this in data.lua? There would be no game available, try control.lua.

nope, this is in control.lua
I just for a joke deleted control.lua from the require list in data.lua and the game booted, I do not remember reading about this anywhere, But it booted at least.

[prg]

What made you think requiring control.lua from data.lua would be a good idea? It certainly doesn't belong in there.

I never actually used custom code in EE before, So I never learned how to use control.lua good enough to know, I just assumed so.

The only way I can think of is to check player.opened every tick/few ticks and do things whenever it changes.

So, now I have this:

Code: Select all

game.on_event(defines.events.on_tick, function(event)
a = game.player.opened
if(a == "energy-condenser")
then
	game.player.print("The game detected the opening of the energy condenser")
elseif(a == nil)
then[quote][/quote]
	game.player.print("its still nil")
elseif(a == "container.energy-condenser")
then
	game.player.print("its the thing in the code")
else
	game.player.print("its something else")
end
end)

but every time I open the energy condenser it just says "its something else". And if nothing is opened (obviously) it says "its still nil" so I have tried a load of different things that game.player.opened might be, but I can't figure it out. The wiki says this:

Lua/Entity The entity that owns the GUI the player currently has open. Nil if none.

So the wiki didn't really tell much for use (for me).

my entities.lua contains this: (snippet)

Code: Select all

type = "container",
    name = "energy-condenser",

So what actually is stored in game.player.opened?

[Rseding91]

The LuaEntity object that was opened.

[matjojo]

The LuaEntity object that was opened.

yeah, but what would that be when the same of the entity opened is "energy-condenser"
note: I did try to print game.player.opened, it didn't work.

[ratchetfreak]

in other words a.name == "energy-condenser" will be the true

[matjojo]

in other words a == "energy-condenser" will be the true

but, it does not, As said, it prints "its something else", which only gets printed if game.player.print ~= "energy-condenser" or nil.

so it is something else.

Because it's the LuaEntity: https://forums.factorio.com/wiki/inde ... Lua/Entity

It's a reference to the entity opened.

[Klonan]

you need to call the 'if' on not the entity, but the entities name

so in your case you would go

Code: Select all

if a.name =="energy-condenser" then game.players[1]print("Found condensor")

[ratchetfreak]

in other words a == "energy-condenser" will be the true

but, it does not, As said, it prints "its something else", which only gets printed if game.player.print ~= "energy-condenser" or nil.

so it is something else.

sorry I forgot to add the ".name" after pasting

that worked, be sure never to check "if a.name == nil" that will break the game. but just checking "if a.name == "energy-condenser"" does work. (even if it is nil)
