Mission: Battle analysis of hexagon based wargames using wargame calculators.

Design Issues

Components: Wargame Rules, Map, Force, Terrain

Wargame Rules Sequence of play that records turns, phases, victory conditions and modes of play

Map of the battle with hexagon grid for unit placement, line of sight and lines of communication

Force combat units involved represented by counters placed on the map

Terrain with terrain types that affect movement and combat

Rules and Calculators

• Hexagon Library with:
• wargame grid cartesian coordinate system to place units on map and record terrain data.
• hexagon name calculator to convert hexagon names to coordinates.
• line of sight algorithm
• line of sight calculator to check for blocked terrain.
• lines of communication calculator to check for supply.


• WARGAME RULES with:
• wargame calculator game phase, game mode, turn count, weather, morale, panic
• victory calculator


• MOVEMENT RULES with:
• move calculator with TEM terrain effects
• lines of communication calculator
• stacking calculator
• zone of control calculator


• COMBAT RULES with:
• combat calculator with TEC terrain effects chart
• combat results table calculator
• line of sight calculator

Model View Controller Design Pattern

View - web page with mouse events

Controller - convert events into commands, apply commands using wargame rules

Model - data

• wargame data stores information about the status of the wargame (e.g. phase, mode, turn, weather).
• terrain data for hexagons (e.g. city, forest), hexsides (e.g. rivers, streams) and hexagon edges (e.g. slopes) and paths (e.g. roads)
• force data stores information about the forces and the units
• map data stores information about the maps coordinates
