Interactive Expie

🐾 Expie Petting and Interaction Mod

An interactive, high-fidelity physical and psychological BepInEx mod for Casualties: Unknown that lets you interact with your experiment subject ("expie") like a beloved, physical pet.

This mod introduces custom physics dragging/tugging forces, petting gestures, comforting neurological benefits, a satiety-fatigue simulation, and highly reactive sensory feedback depending on the subject's physical state.

✨ Features

1. 🧲 Physical Mouse Grabbing & Tugging

• []Grab and Drag: Hold the configured modifier key (default: Left Alt) and Left-Click on any physical limb in the world to grab and drag it.[/]

  []Spring Physics: The grabbed limb is realistically pulled towards your mouse cursor using a fully physical 2D spring-damper calculation.[/]

  []Tug-to-Flop: Grabbing and dragging a limb while the subject is standing up temporarily makes only that limb dynamic and floppy, allowing you to stretch or position it while the rest of the body maintains its standing animation.[/]

  []Strain Discomfort: Dragging limbs too far beyond their range or pulling on dislocated/broken parts causes immediate localized pain spikes, tension stretch sound effects, and distressed vocalizations.[/]

  []Anti-Flying Physics Ceiling: While the subject is ragdolled, dragging targets are dynamically clamped via a downward raycast checking the "Ground" layer. You can drag and slide them horizontally across any platforms, ramps, or sloped surfaces, but lifting them high into the air is blocked, neutralizing the flying physics exploit.[/]

2. 🫳 Cozy Petting & Stroking

• []Stroking Gesture Verification: Petting requires active hand-stroking movement above a customizable velocity threshold (MinPettingSpeed). Simply hovering or holding your cursor stationary over a limb will not trigger petting.[/]

  []Soothing Neurological Benefits: Petting healthy limbs slowly heals active limb pain, increases overall character happiness, and reduces emotional trauma/stress.[/]

  []Micro-movements & Nuzzling: When petted on the head, the expie will physically lift and tilt their head into your cursor to simulate nuzzling.[/]

  []Happy Cooing: Healthy subjects express deep contentment through soft sighs, purrs, or high-pitched cozy whimpers.[/]

3. 🥱 Petting Saturation & Satiety

• []Per-Body Satiety Tracking: Satiety levels are tracked independently for each specific Expie body instance, allowing you to interact with multiple subjects naturally.[/]

  []Comfort Fatigue: Over-petting causes the expie to gradually grow tired of physical contact. Satiety accumulates over continuous stroking.[/]

  []Diminishing Comfort Efficiency:

  [] 0% to 50% Satiety: Full comfort and maximum mood boost efficiency.[/]

  []50% to 100% Satiety: Satiety sets in, smoothly scaling comfort and healing efficiency down to 0%.[/]

  []100% Satiety (Over-stimulation): The expie is completely indifferent. No mood upgrades, pain relief, or happy vocalizations are triggered.[/]

[]Persistent Moodles & Decay:

• [] Satiating Petting Moodle: Once satiety reaches 50%, the light-green Satiating Petting moodle remains continuously visible on the HUD, even when you stop petting, until it slowly decays back below the 50% threshold.[/]

  []Permanent Indifference Moodle: Once satiety reaches 100% (indifference is triggered), it is permanently locked at 100% for that specific Expie body and never decays. The orange Petting Satiety moodle remains visible permanently on the HUD for that subject body.[/]

🩹 Sensory Pain & Wounded Reactions

• []Hypersensitivity: Petting a body part with skin damage (active wounds or burns) triggers intense localized pain spikes, adrenaline shock surges, and a severe drop in happiness.[/]

  []Agonizing Vocalizations: Petting wounded parts triggers intense vocal screams and high-volume distress lines.[/]

  []Unconscious Spasms: Touching/petting active wounds on an unconscious subject causes physical reflexes (sudden spasms/convulsive twitches) accompanied by low, painful groans.[/]
