Iron Dome

The IDF's Iron Dome air defense system, ported from the original Garry's Mod addon to s&box. When an interceptable projectile enters the dome's detection radius, the dome plays the IDF Red Alert siren and launches a missile on a predictive intercept path solved by a quadratic intercept equation. The missile detonates on proximity, destroying the threat and playing a layered close/distant explosion. Multiple domes coordinate through a shared target registry, so two domes never engage the same target. Variants - Neutral — engages every interceptable target above its elevation - Protective — same as Neutral but skips projectiles owned by the dome's network owner - Admin — infinite missiles, no reload, 15000 unit detection radius For the dome to intercept an object - The object must have a Rigidbody component - The object must carry the "interceptable" tag (Tags panel in the editor, or gameObject.Tags.Add("interceptable") in code) - The object must be above the dome on the Z axis - The dome must have line of sight to it - The object must not already be claimed by another dome ConVars (runtime tunable) - iron_dome_max_health 1000 Dome health (blast damage only) - iron_dome_siren_volume 1.0 Siren volume - iron_dome_reload_time 10 Seconds per reload cycle - iron_dome_missiles_per_reload 20 Missiles loaded per cycle - iron_dome_missile_speed 3500 Interceptor speed in units per second - iron_dome_detection_radius 8000 Scan radius (Admin variant overrides to 15000) Health - Domes take blast damage only — bullets and small arms do nothing - Explosions within the dome's blast radius can chain-detonate adjacent domes Credits - Iron Dome model — Chenzoss - Red Alert siren — ShalevDZN - Original GMod addon and s&box port — PoorTuna
