VRChat Magnetic Interaction System

Add realistic, physics-driven magnetic behavior to your VRChat worlds with this modular Magnetic Interaction System.
This asset gives world creators intuitive, drop-in magnets that feel right — responsive, physical, and stable in VR.

Designed from the ground up using acceleration-based physics, these magnets preserve gravity, collisions, and natural motion while delivering satisfying attraction, repulsion, and snap behavior.

✨ What’s Included (v1)

🔹 Soft Pull Magnet

A smooth, gravity-friendly magnetic pull that:

• Gently attracts objects within range
• Pulls harder as objects get closer
• Stops cleanly at a configurable distance
• Automatically resumes pulling if objects are separated again

Perfect for:

• Puzzle pieces
• Floating props
• Sci-fi effects
• Ambient world interactions

🔹 Polarity Magnet (North / South)

A true two-pole magnet system with realistic behavior:

• Separate North (+) and South (−) pole positions
• Opposite poles attract, same poles repel
• Objects rotate and align naturally as they connect
• Strong snap near contact without jitter or buzzing
• Stable stop / resume logic to prevent vibration

Perfect for:

• Physics puzzles
• Modular props
• Educational worlds
• Toy-like interactions

🔹 Charged Magnet (Single Polarity)

A simpler positive / negative charge system:

• Each object has a single charge (+ or −)
• Opposites attract, same charges repel
• Shared tuning style with the polarity magnet
• Optional rotational alignment for extra realism
• One-slider overall strength control for easy balancing

Perfect for:

• Game mechanics
• Energy-based systems
• Abstract or sci-fi designs

⚙️ Key Features

• Gravity-preserving physics (no “floaty” behavior)
• Acceleration-based magnet forces (feels natural in VR)
• Adjustable:
  • Magnetic strength
  • Snap intensity
  • Pull radius
  • Stop & resume distances
• Optional alignment torque (magnets rotate into place)
• No tags required (Udon-safe, component-based)
• Trigger-based detection for performance & stability
• Clean prefab structure, easy to customize
• Designed for VRChat + UdonSharp best practices

🧱 Setup Overview (Simple)

1. Add a Rigidbody + Collider to your object
2. Add the magnet script (Soft Pull / Polarity / Charged)
3. Place the included empty transforms (poles or charge point)
4. Adjust strength and radius in the inspector

That’s it — no scripting required.

🎮 Use Cases

• Physics & logic puzzles
• Modular building systems
• Interactive toys
• Educational simulations
• Sci-fi or fantasy props
• World ambience & polish

🛠️ Technical Notes

• Built with UdonSharp
• Uses trigger volumes (no expensive physics forces)
• Stable stop/resume logic to prevent jitter
• Designed to be network-friendly (ownership handling can be layered on if needed)
