Stealth Mechanics – Player Detection System

Stealth System is a modular stealth framework for Unity, built to help you create detection-driven gameplay using vision, sound, and light-based sensors. It provides flexible detection components, behavior modules, and ScriptableObject-based configuration so you can design stealth mechanics that fit your game without rewriting core logic.

The system is built around a simple idea: separate sensing, detection logic, and behavior response into clean, reusable modules. This lets you prototype quickly, fine-tune stealth rules, and scale from small scenes to complex AI-driven levels.

💬 Stealth System – Core Capabilities

👁️ Modular Vision Detection

Configurable vision cones with adjustable angle, distance, and obstacle checks.

Supports line-of-sight validation and flexible detection thresholds.

🔊 Sound-Based Detection

React to player-generated noise (movement, actions, environment).

Tune hearing radius, sensitivity, and reaction timing per AI type.

💡 Light & Visibility Awareness

Optional light-based modifiers that influence detection strength.

Adapt stealth difficulty based on illumination, exposure, or custom visibility logic.

🧠 Behavior Modules

Plug detection results into modular behavior responses: patrol, investigate, chase, alert, return-to-post.

Designed to integrate cleanly with your existing AI or state machine system.

📦 ScriptableObject Configuration

All core parameters are data-driven via ScriptableObjects.

Create different guard types, difficulty presets, or level-specific stealth rules without touching code.

⚙️ Clean & Scalable Architectur

Separation of sensors, detection logic, and response layers.

Built to scale from simple prototype stealth to production-ready AI systems.

🎮 Best Fit Genres

Stealth System works especially well for:

✅ Stealth action and tactical infiltration games

✅ Action-adventure titles with stealth sections

✅ RPGs with guard/NPC awareness mechanics

✅ Survival and horror games with detection pressure

✅ Top-down or isometric stealth gameplay

✅ Simulation or sandbox projects with AI awareness systems

✅ Prototypes and vertical slices requiring stealth mechanics

⭐ Why Choose Stealth System?

Because it gives you a modular, sensor-based stealth foundation instead of a hardcoded “one-guard script.” Vision, sound, and light detection are configurable, extensible, and ready to plug into your AI pipeline.

Less custom detection code – more focused stealth design.
