Example 1 with UnitType

use of games.strategy.engine.data.UnitType in project triplea by triplea-game.

the class BattleCalculator method sortUnitsForCasualtiesWithSupport.

/**
 * The purpose of this is to return a list in the PERFECT order of which units should be selected to die first,
 * And that means that certain units MUST BE INTERLEAVED.
 * This list assumes that you have already taken any extra hit points away from any 2 hitpoint units.
 * Example: You have a 1 attack Artillery unit that supports, and a 1 attack infantry unit that can receive support.
 * The best selection of units to die is first to take whichever unit has excess, then cut that down til they are both
 * the same size,
 * then to take 1 artillery followed by 1 infantry, followed by 1 artillery, then 1 inf, etc, until everyone is dead.
 * If you just return all infantry followed by all artillery, or the other way around, you will be missing out on some
 * important support
 * provided.
