Mob Senses Mobs Hear Sound Light & Voice Chat Mod gives hostile mobs real senses like hearing, sight, and smell. Instead of only spotting you within a fixed vanilla distance, monsters react to footsteps, block noises, held torches, and blood trails. When paired with Simple Voice Chat, nearby enemies even hear you talking through your microphone. It works on the server alone so vanilla clients can join without extra files, while adding it to your client unlocks an on-screen stealth meter.

Features:

Sound Detection: Mobs walk over to check out noises from sprinting, breaking or placing blocks, opening doors and chests, fighting, shooting arrows, explosions, bells, note blocks, and eating.
Surface and Wall Physics: Walking on wool quiets your footsteps while gravel gives you away, and thick stone walls block sound much better than wood, glass, or open doors.
Voice Chat Tracking: Monsters hear you speak when Simple Voice Chat is installed, measuring shouts and whispers against your normal speaking volume so quiet microphones give no unfair advantage.
Light and Darkness: Holding a bright torch or lantern makes you easy to spot from far away, while sneaking in dark areas keeps you hidden.
Blood Scent Trails: Dropping to half health or lower leaves a blood trail behind you that zombies and spiders actively follow.
Client Stealth HUD: Installing the mod on your client displays a small indicator showing your current noise level, light exposure, voice activity, and blood scent.
Runs on the server without changing network protocols, letting players with vanilla clients join and play against the smarter mob senses.
Works alongside other mob AI mods by giving the noise check a low priority that stops right away once combat starts.
Uses the #mobsenses:listeners tag to control which custom or modded mobs investigate sounds.

Sense Presets:

Off: Mobs act just like they do in vanilla Minecraft.
Subtle: Lowers hearing to x0.6 and sight to x0.8, built for building servers where mobs only notice loud noises.
Default: Sets hearing and sight to x1 for normal survival play.
Hardcore: Boosts hearing to x1.6 and sight to x1.3 for horror and hardcore worlds where every step matters.
