Contains the arguments passed in the opening BBCode tag. By default, arguments are strings; if their contents match a type such as [bool], [int] or [float], they will be converted automatically. Color codes in the form [code]#rrggbb[/code] or [code]#rgb[/code] will be converted to an opaque [Color]. String arguments may not contain spaces, even if they're quoted. If present, quotes will also be present in the final string.
For example, the opening BBCode tag [code][example foo=hello bar=true baz=42 color=#ffffff][/code] will map to the following [Dictionary]:
If [code]true[/code], the character will be drawn. If [code]false[/code], the character will be hidden. Characters around hidden characters will reflow to take the space of hidden characters. If this is not desired, set their [member color] to [code]Color(1, 1, 1, 0)[/code] instead.
