Color3 argument to a command?

[jakej78b]

I've kinda got a start on th is, I'm new to using string.gmatch so I'm not sure if this is right or not.
Also, is there like a HUD element to create a color3 picker like the one on the Colour tool in the spawn menu?
I'd like to somehow add that into xgui.

Code: Lua

1. function ulx.tag( calling_ply, tag, color)
2.         local r,g,b
3.         for i,word in string.gmatch(color, ",") do
4.                 if i == 1 then
5.                         r = word
6.                 elseif i == 2 then
7.                         g = word
8.                 elseif i == 3 then
9.                         b = word
10.                 elseif i > 4
11.                         ULib.tsayError( calling_ply, "Invalid color format. Use !tag <r,g,b> <tag text>", true )
12.                 end
13.         end
14.                
15.         end
16.         ulx.fancyLogAdmin( calling_ply, "#A changed their tag to #s with Color(#s)", tag, color )
17.  
18.  
19. end
20. local tag = ulx.command( "Fun", "ulx tag", ulx.tag, "!tag" )
21. tag:addParam{ type=ULib.cmds.StringArg, hint="color" }
22. tag:addParam{ type=ULib.cmds.StringArg, hint="text", ULib.cmds.takeRestOfLine }
23. tag:defaultAccess( ULib.ACCESS_ADMIN )
24. tag:help( "Sets tag with color and text." )
25.  

Also, is there a max length property I could apply to a string, or would I need to add this in the code? I wanted to max out the length they could set their tag to about 10.

I personally think it would be better to use NumArg, with each min=0 and max=255 if you want people to have the full RGB range. Then you could easy just set it to like: "Color( r, g, b )".

When it comes to the string length, I don't think StringArg has any "max_chars" (or similar) to it. So you'd have to use something like string.len in your code.

Could I still do that with just One Number argument though? Or would I need to use 3. I'd prefer to use 1 just to keep it as simple as possible but I suppose 3 would be alright.

[Decicus]

Not really. I mean, there is string.Comma, but it returns a string, which wouldn't directly work using Color().

Even then, you'd have to make sure the number has at least 9 characters (so string.Comma works as it should), which is possible, but then you'd most likely have to use string.len again to count... but that's for a string, not numbers.

As I see it, using 3 arguments would be the best, someone else might have a better idea though.

Use 1 stringarg (i.e. "255 255 255 255"), and use string.ToColor to get a color argument from it.

There is not currently a way to implement a color picker on the Cmds tab in XGUI. You could create a module for XGUI and use it elsewhere, but that's a bit more work.

[jakej78b]

I'll probably just write a module and place it in the 'Settings' looking off of a base module to get the skeleton. I'm sure I'll need some help after I run into problems.
