Highly configurable Skyrim-style stealth awareness, sneak attacks, invisibility break rules, and sneak attribute system.

Features

Light, distance, facing, sound, armor, invisibility, and line-of-sight based stealth detection.
Sneaking players can avoid hostile mob target acquisition while undetected.
Synced stealth eye indicator with hidden, suspicious, searching, and detected states.
Detection rises through the awareness cycle instead of snapping straight to detected.
Configurable melee, one-handed, dagger, and ranged sneak attack multipliers.
Sneak attack particles, feedback messages, and attack noise.

Configuration

(Recommended to use the Configured mod)

Config file: config/shadow_walker-common.toml.

Options:

enableStealthSystem: master switch for stealth awareness, targeting suppression, and sneak attacks.
showStealthCrosshair: toggles the stealth eye overlay.
removeInvisibilityOnAttack: removes vanilla invisibility from players after they damage another entity. Defaults to true.
sneakLevel: global stealth proficiency from 0 to 100. This stacks with the player's shadow_walker:sneak attribute, which starts at 0 and is capped at 100.
maxScanRange: upper bound for mob awareness scans.
crosshairDetectionRange: radius, in blocks, where detected mobs can affect the stealth eye. Defaults to 24.
armorNoiseMultiplier: controls how much armor contributes to sneak noise.
meleeSneakAttackMultiplier, oneHandedSneakAttackMultiplier, daggerSneakAttackMultiplier, rangedSneakAttackMultiplier: damage multipliers.

Ranged sneak attacks use Minecraft damage types tagged as projectiles.
Melee sneak attacks happen when the direct damage entity is the attacking player.
Daggers use the shadow_walker:daggers item tag, with a fallback for item registry paths containing dagger.
One-handed melee weapons are non-heavy SwordItem, AxeItem, TridentItem, or other TieredItem instances.
Heavy melee weapons are detected by registry paths containing greatsword, battleaxe, warhammer, claymore, halberd, glaive, or scythe.
