Bevy Newton - Newtonian Physics for Bevy

crates.io license documentation

A feature-rich Newtonian physics engine natively integrated with the Bevy game engine.

Features

  • 🚀 Rigid Body Dynamics
    • Linear & angular velocity integration
    • Mass properties and inertia tensors
    • Force/torque accumulation
  • 🔥 Collision Detection
    • Sphere, Box, Capsule, and Convex Hull primitives
    • Broad-phase spatial partitioning
    • Narrow-phase SAT (Separating Axis Theorem)
  • ⚡ Collision Resolution
    • Impulse-based contact resolution
    • Restitution (bounciness) and friction
    • Collision events and queries
  • 🧠 Advanced Features
    • Continuous collision detection
    • Raycasting and shape queries
    • Joint constraints (ball, hinge, prismatic)
    • Force fields and area effects
