pub struct FightEngine { /* private fields */ }
Expand description

Bounded, deterministic driver for fight simulations.

Implementations§

Source§

impl FightEngine

Source

pub fn new( game_config: SharedGameConfig, behaviors: Arc<BehaviorRegistry>, seed: Seed, ) -> Self

Source

pub fn start( &mut self, state: OverlordState, prepare_fight_type: PrepareFightType, ) -> Result<FightSim, FightError>

Prepare a fight on a copy of the player’s state. Any pre-existing active_fight is discarded — the sim owns the whole fight lifecycle.

Source

pub fn step( &mut self, sim: &mut FightSim, ) -> Result<Option<FightResult>, FightError>

Advance the fight by exactly one game tick (100 ticker units). Returns Some(result) once the fight has ended.

Source

pub fn run( &mut self, state: OverlordState, prepare_fight_type: PrepareFightType, max_game_ticks: u64, ) -> Result<FightOutcome, FightError>

Run the fight to completion, executing at most max_game_ticks steps. Total by construction: always returns, with FightResult::Undecided when the budget is exhausted.
