Useful WML Fragments

Most of the things found here are macros (see PreprocessorRef) that must be copied into a scenario file or another file included first by the campaign, and then used in the scenario (or multiplayer map). Remember that a macro cannot be used at a point before it is defined.

Also, when creating or using macros, please remember: Every macro must generate a WML fragment which would be syntactically balanced and correct by itself. Unbalanced macros confuse our maintenance and sanity-checking tools, creating extra work and headaches for the already-overworked WML maintainers.

Note: some of the code here is outdated or otherwise poor. It's not advisable to blindly copy-paste code from here and expect it to work on recent Wesnoth versions or assume that the recent versions don't support a simpler and less hacky way of doing the same thing.

Some things not to do here:

Don't add macros that duplicate things in the core macro library.
Don't add macros that are trivial syntax shortcuts.
Don't add macros that generate unbalanced syntax fragments.

Try to avoid adding pages here. It is better to find a category in which your code fits and add it to that page.

Logic Structure Macros

WML Utilities: Macros to assist other macros. Overlay with Filter. Determine Opposite Coordinates. Find nearest hex(es)

RPG Tools

A Shop Like Thing: How to add even more RPG elements to your scenarios.
CutsceneWML: Fixed MOVE_TO event (uses FIND_NEARBY from WML Utilities), move + exit to recall list, define character dialogue and a "main character", grant unlimited moves.*

Music Tools

WML Musical Moods: Groups the Wesnoth music (as of 1.7.x) into "moods" and defines macros for playing randomly songs from these pools and for quickly switching music.

Unit Tools

WML Abilities: Knockback. Charm. Bloodlust.

Item Tools

DroppableItem: For placing items on the terrain upon death of a unit.

Map Tools

FloodWML: Macros to create a flood of a certain terrain type spreading across the map.

Advanced WML

Advanced Optimisations and Hacks: If you're coding something really complex, this might come handy
