NOTES ABOUT ADDING PAGES: Don't add new pages here. Find a category in which your code fits and add it to that page.
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.
For a step by step instruction, look here: HowTo: IncludeMacros and then here: HowTo: UseMacros
High level macros often require the lower level macros found in ProgrammingMacros, Utilities, and Scenario Tools.
Logic Structure Macros
- ProgrammingMacros: Definitions for some low-level macros to make it easier to write program-like WML.
- WML Utilities: Macros to assist other macros. Test Value of Variable. If Have Unit. Store Unit Attribute. Filter by Terrain. Iterate. Overlay with Filter. Determine Opposite Coordinates.
Campaign Tools
- WML Scenario Tools: Macros directly useful in a scenario. Modify unit. Give villages to a side. Return Unit to Recall List. Trap Unit. Change Keep Terrain. Hero die message. Item effect.

Unit Tools
- MoveExistingUnit: Move a unit from one place to another, displaying its movement. Move Unit 1. Move Unit 2. Move Unit 3.
