Detailed Description

Computes the statistics of a battle between an attacker and a defender unit.

Definition at line 177 of file actions.hpp.

Constructor & Destructor Documentation

battle_context::battle_context	(	const unit_map &	units,
		const map_location &	attacker_loc,
		const map_location &	defender_loc,
		int	attacker_weapon = `-1`,
		int	defender_weapon = `-1`,
		double	aggression = `0.0`,
		const combatant *	prev_def = `NULL`,
		const unit *	attacker_ptr = `NULL`
	)

If no attacker_weapon is given, we select the best one, based on harm_weight (1.0 means 1 hp lost counters 1 hp damage, 0.0 means we ignore harm weight).

prev_def is for predicting multiple attacks against a defender.
