Game Role

Starter unit — pre-placed by the server during the Prepare phase. No build cost paid on spawn; the build_costs block above documents the cost when the player places one mid-match from the build bar.
Auto-targeting — fires at the closest hostile inside range whenever cooldown_secs elapses since the last shot.
Single-shot ballistic — emits one projectile per volley travelling at projectile_speed units/s, expires after projectile_lifetime seconds.

Tuning surface

The server pulls all combat numbers from this file at boot via MapDb::from_bytes + get_object_def_by_ref("nd-tower-basic"). Adjusting the YAML and re-running nx run astro-kbve:sync:mapdb retunes the live build without recompiling the Rust binary.

max_health → BuildingTag HP / max_HP
ranged_attack.range → target acquisition radius
ranged_attack.cooldown_secs → ticks between shots (rounded against SIM_TICK_HZ)
ranged_attack.damage_per_shot → projectile damage
ranged_attack.projectile_speed → projectile velocity
ranged_attack.projectile_lifetime × projectile_speed → max range before self-despawn
