ClimbStamina

Climbing costs stamina. Hang too long and your grip gives out.

Features

• Shared stamina pool for both hands: hanging one-handed drains 10/s, both hands share the load at 5/s (defaults), and actively pulling upward costs 1.3x
• Hanging is what drains — standing on the floor (or a ledge) while holding a rung costs nothing. Detection uses the game's own climb/hang physics state, so feet brushing the wall mid-hang won't pause the drain
• Exhaustion: at zero both hands force-release and climbing grabs are blocked until the bar refills (default: all the way to 100%). Guns, props, doors, NPCs, and every other interaction are never affected
• Regen: 20/s while standing, 5/s while airborne, after a 1 s delay (defaults)
• World-space stamina HUD: rounded bar with a thin outline, percent label, amber/red warning colors and a pulsing glow when low; it slides toward you instead of clipping into the wall you're climbing
• BoneMenu settings page: every rate, threshold, and toggle is adjustable live; optional avatar strength scaling (0.70x–1.30x from the avatar's upper-body strength stat)
• Haptic danger curve: below 35% stamina your gripping hands pulse — smoothly stronger and faster as the bar empties (never tier-switched), only on hands that are actually climbing, with one strong release pulse when your grip gives out. Toggle and strength in BoneMenu
• Panic grab: catch a climbable surface mid-fall (4+ m/s down) and it costs an instant 20% stamina, drains faster for a second while your grip steadies, and thumps the catching hand — configurable, with a cooldown so it can't spam
• Restrained notifications: just "Grip weakening…" and a throttled notice if you grab while locked out - exhaustion and recovery have no popups

Requirements

• MelonLoader 0.7.x
• BoneLib 3.2.2+

Both are installed automatically when you use a Thunderstore mod manager.

Installation

Recommended: install with a Thunderstore mod manager (r2modman / Gale) — dependencies are handled for you.

Manual: with MelonLoader and BoneLib installed, copy Mods/ClimbStamina.dll from this package into your BONELAB Mods folder.

Usage

Grab bare level geometry, ladder rungs, or wall bars and the bar appears. It drains while your hands are what's holding you up and refills when you stand, let go, or land. Run it to zero and you fall — climbing stays locked until the bar refills to the configured percent. Tune everything in BoneMenu → Climb Stamina.

Compatibility

• BONELAB Patch 6 — built and tested against it
• Fusion — runs local-only alongside it: grip events are filtered to your own rig, and releases go through the game's standard detach path, which Fusion relays. Stamina is not synchronized between players
• Climb-anywhere mods — surfaces made grabbable through the game's real grip system are covered by the stamina rules automatically
