- themes are used both for the wesnoth game and the wesnoth editor - themes are stored in data/themes, one theme per file. - themes allow flexible configuration of how everything is laid out on-screen - format of a theme is:

Code:

[theme]
    name=<name>
    [resolution]
    width=<x>
    height=<y>
        ....'content tags'....
    [/resolution]
    ...more resolution tags...
[/theme]


  • the [resolution] tags are scanned until the first one which is of the same or lower resolution than is currently being

used is found, and this is used as our theme. This allows us to define themes to work differently on different resolutions, and will allow us to support both high and low resolutions elegantly.

  • the 'content tags' define where everything goes on-screen. The most common content tag is the 'main_map' tag, it has

the following format:

Code:

[main_map]
    rect=x1,y1,x2,y2
    xanchor=left|right|fixed|proportional
    yanchor=top|bottom|fixed|proportional
[/main_map]


The purpose of the 'main_map' tag is to define where the main game display (i.e. all the hexagons and units) is displayed. The rect field defines the rectangle the map is displayed on. The rectangle is given for a 1024x768 display -- the game's "canonical" resolution.

xanchor and yanchor control the behavior of how this rectangle changes as the resolution changes.

  • A rectangle anchored to the left will have its distance from the left side of the screen always remain the same, while

changes in the resolution will change its size by the same amount (top for the y axis).

  • A rectangle anchored to the right will have its size always remain the same, as well as its distance to the right side

of the screen (bottom for the y axis).

  • A rectangle that is fixed will have its co-ordinates in that axis remain constant
  • A rectangle that is proportional will have its co-ordinates multiplied by the ratio of the resolution being used to

the canonical resolution.


mini_map

determines where the mini map is displayed

main_map

determines where the mini map is displayed


label

displays a text label on screen.

  • prefix a string that will be printed before the text in all language
  • text a text string id to be displayed

  • image the image to use if available
  • is_context_menu if set to true this menu will not be placed, but displayed on a right click

status

this tag contains many other tags, which determine where other game statistics, such as the current turn, and a description of selected units go. For instance, the time_of_day tag will determine where the time of day image goes. each subtag can contain the following attributes

  • font_size the size of font to use for the status
  • rect the rectangle as for the main_map attribute
  • xanchor the x-wise anchoring as for the main_map attribute
  • yanchor the y-wise anchoring as for the main_map attribute
  • prefix the string to display before the actual status, this is the string id for internationalisation
  • prefix_literal a string to put after the prefix, but before the label for all languages.
  • postfix_literal a string to put after the status
  • postfix the string to display after the postfix_literal, this is the string id for internationalisation

the following status are recognised
