Description

helios::engine::mechanics::combat

Combat-related gameplay systems, components, and commands.

Overview

This module provides all building blocks for implementing combat mechanics such as aiming, shooting, projectile spawning, and attack attribution.

Submodules

Submodule	Purpose
commands/	Commands for combat actions (ShootCommand, Aim2DCommand)
components/	Data containers for combat state (aiming, cooldowns, attack tracking)
systems/	ECS systems for processing combat logic (ProjectileSpawnSystem)
types/	Combat data types (AttackContext)

Key Classes

Class	Purpose
Aim2DComponent	Stores aiming direction and fire frequency
ShootComponent	Weapon cooldown, spawn profile reference, emitter state
LastAttackerComponent	Tracks last entity that attacked this entity
AttackContext	Data struct with attacker info for kill attribution
Aim2DCommand	Updates aim direction from input
ShootCommand	Triggers projectile spawn when cooldown allows
ProjectileSpawnSystem	Reads shoot state and enqueues spawn commands

Architecture

Combat follows the command pattern integrated with the spawn system:

1. Input systems generate ShootCommand and Aim2DCommand 2. Commands update ShootComponent and Aim2DComponent state 3. ProjectileSpawnSystem reads component state and generates SpawnCommand 4. Spawn system handles actual projectile creation via pool and profile

Attack Attribution Flow

1. DamageOnCollisionSystem applies damage and updates LastAttackerComponent 2. HealthUpdateSystem detects death and publishes DeathEvent with AttackContext 3. CombatScoringSystem reads DeathEvent and awards score to attacker
