Conversation
When improved hostage AI (hostage_ai_enable 1) is used in CS 1.6, hostages panic and scatter in response to gunfire, explosions and nearby deaths. Setting mp_hostage_fear 0 keeps them calm, restoring 1.6-like hostage behavior while retaining the rest of the improved AI.

Addresses the hostage panic/scatter part of #1125.
What
New cvar
mp_hostage_fear(default1- vanilla behavior) that controls whether hostages driven by the improved AI (hostage_ai_enable 1) get scared of gunfire, explosions and nearby deaths. Withmp_hostage_fear 0hostages stay calm: they don't panic, don't scatter and don't refuse to follow after nearby shooting - CS 1.6-like hostage temperament while keeping the rest of the improved AI (navigation, chatter, animations).Why
With
hostage_ai_enable 1on CS 1.6 hostage maps, any nearby enemy gunfire frightens the hostages (CHostageImprov::OnGameEvent->Frighten(SCARED/TERRIFIED)). Scared hostages scatter, crouch and refuse to follow the rescuer, which #1125 reports as disruptive on 1.6 servers, where the original hostages ignore gunfire completely. Server operators currently have no way to keep the improved AI but disable the fear reactions.How it works
All fear-driven behavior (fleeing in
HostageIdleState, refusing to follow, scared/afraid animations) is gated byCHostageImprov::IsScared(), which is true only whilem_scaredTimeris running - and that timer is started exclusively inCHostageImprov::Frighten(). So a single early return inFrighten()whenmp_hostage_fearis0keeps hostages calm everywhere. The cvar is evaluated on every call, so it can be flipped at runtime without a map change or server restart.Edge cases
OnInjury->m_mustFleein the idle state). That path is deliberately not gated: fleeing from an actual injury is self-preservation, distinct from panicking at noise.hostage_ai_enable 0) is unaffected - it has no fear logic at all.1keeps vanilla behavior; vanilla builds are unaffected (the check is under#ifdef REGAMEDLL_ADD).Tested
Windows build (MSVC), verified on a ReHLDS server with
hostage_ai_enable 1:mp_hostage_fear 1(default): hostages panic, scatter and refuse to follow when a Terrorist fires nearby - unchanged behavior.mp_hostage_fear 0(set at runtime, no restart): hostages stay calm under fire and keep following normally.
