Greetings,

I would like to know the following:

1. How would I be able to compare the current player color with a color table of my own (granted my own table has the full rgba).
eg.

Code: Select all

if (game.player.color == mycolors.white || game.local_player.color == mycolors.white) then
--#change player color

2. What is the best way to iterate through my table ?
eg.

Code: Select all

If (game.player.color in mycolors) then
--#true/false

3. I have no idea how to work with guistyle.
I created this:

Code: Select all

data.raw["gui-style"].default["my_label"] = 
{
	type="label_style",
	parent="label_style",
	color={r=1,g=1,b=1},
	fontcolor={r=0,g=0,b=0}
}

Code: Select all

path["flow"..ii].add({type="label",name="label"..ii, caption="caption", stype="my_label"})

However, whenever I try and use it in my code, it gives me an error stating that my_label doesn't exist... Can someone please explain this to me ? The wiki of guistyle only states the properties, but doesn't give a default value, min/max value, or any form of example of implementation.
4. I tried doing inline styles, and it will tell me that the key value doesn't exist
eg.

Code: Select all

player.gui.top.frame["flow"..ii]["label"..ii].style.fontcolor 	= {r=1,g=1,b=1}

The player color is also rgba, but game.local_player.color == mycolors.white will only ever be true if both colors are exactly the same table, not just tables that happen to contain the same values. You could try something like

Code: Select all

function compare_colors(c1, c2) return c1.r == c2.r and c1.g == c2.g and c1.b == c2.b and c1.a == c2.a end

But since the color values are floats you might want to see if they are close enough together instead of exactly the same.

for _, v in pairs(mycolors) do
    if compare_colors(game.local_player.color, v) then
        --color found
        break
    end
end

Never done anything with that, either.

Thanks for the assistance.

Was wondering about the table values as well... Will compare values instead then, thank you very much!

GUIstyle isn't documented very well, and I can't find a solid working example of implementation.

I have tried downloading some GUI's that are currently available, but when I try copy their example, I get the same error.

So I'm not sure what I'm doing wrong.

I'm hoping someone can assist with this!

BTW turns out someone already wrote a deep compare function for tables.

Code: Select all

require "util"
util.table.compare(t1, t2)

Won't work from the console though since you can't use require there. Also won't work if you want to add name="white" or something like that to your own table.

3. Is that in data.lua file or does data.lua request the file with that code?

You can dig the default values from Factorio\data\core\prototypes\style.lua

Also font_color with an underscore.
