Description texts

A description is a part of the value of a menu attribute. It represents a single option in the difficulty selection menu for a campaign, which consists of an image (called the icon) followed by text. When appropriate, the icon should use ImagePathFunctionWML to replace any magenta with a team color.

The description tag uses a special format:

  • ; if another description precedes it
  • * if it should be the default selection
  • &image=text image with one text description
  • &image=text=text2 image with two text descriptions

Single text items are always enclosed in ", and can be joined together (concatenated) with +. This allows the text to contain translatable items and span multiple lines. (Marking text with _ indicates that it is translatable.)

A sample difficulty description tag might look like this:

difficulty_descriptions="&" + "units/elves-wood/elvish-fighter.png~TC(1,magenta)" + "=" + _"Fighter" + "=" + _"(easiest)" +
	";*" + "&" + "units/elves-wood/elvish-hero.png~TC(1,magenta)" + "=" + _"Hero" +
	";" + "&" + "units/elves-wood/elvish-champion.png~TC(1,magenta)" + "=" + _"Champion" + "=" + _"(hardest)"

The utility macros (see UtilWML) {MENU_IMG_TXT icon text} and {MENU_IMG_TXT2 icon text text-2} can be used to create descriptions more easily. The above example would become:

difficulty_descriptions={MENU_IMG_TXT2 "units/elves-wood/elvish-fighter.png~TC(1,magenta)" _"Fighter" _"(easiest)"} +
	";*" + {MENU_IMG_TXT "units/elves-wood/elvish-hero.png~TC(1,magenta)" _"Hero"} + ";" +
	{MENU_IMG_TXT2 "units/elves-wood/elvish-champion.png~TC(1,magenta)" _"Champion" _"(hardest)"}

For still greater clarity, I have the following suggestion: Before the start of the [campaign] tag, create a set of #define commands as follows:

# Image definitions
# NB Don't forget the trailing + symbols for all but the last entry.
#define EASY_IMAGE


#define HARD_IMAGE

# Difficulty ratings
#po: NB be sure to retain the = signs in the translated text.
#define EASY_TEXT


#define HARD_TEXT

You can then use a standard difficulty_descriptions tag that you will rarely need to alter:


Note: The above example assumes three difficulty levels, which gives six difficulty entries - three for the pictures and three for the text. If you have more or fewer than three difficulty levels, make sure that the last entry does not have a trailing plus sign and that all the others do.
