Toolkit for Unity Physics 2027

Force fields, physics shapes and physics maths for Unity's built-in physics, in 2D and 3D. 

Gravity wells, magnets, wind, tractor beams and more, with little or no code.

This asset is included in the Toolkits for Unity Bundle.

Build the forces your game needs and drop them into a scene. Planet gravity, magnets and repulsors, dampening zones, steady wind, tractor beams and breakable objects, all from components and assets you can tune in the Inspector, with a documented API and a maths library underneath for when you want to go further.

✅ Force Effects: gravity wells, magnets, repulsors, tractor beams, dampening fields and wind ✅ Fields that act inside a trigger volume, along a direction, or everywhere at once ✅ Add your own effects with a small, documented interface ✅ Physics Data: the convex hull, volume, surface area and cross section of any object ✅ A physics maths library: intercepts, torque and force helpers, geometry and polynomial solvers ✅ 2D and 3D versions of the force tools, with the same design ✅ Documented API, tested code, example scenes ✅ Live support on Discord from the developers who built it

WHAT'S INCLUDED:

• 🎯 Ballistics Toolkit: Projectile aiming, prediction and simulation in 2D and 3D. Firing solutions for stationary and moving targets, wind and drag, bounce prediction, homing projectiles, turret aiming, a Firing Table window and Burst batch solving with optional Entities (DOTS) support. Perfect for turrets, cannons, grenades, arrows, trick shots and tower defence.
• 🪢 Toolkit for Verlet Motion: Physics-driven motion through a chain of transforms, commonly used to simulate hair, tails, capes, ropes and simple soft-body-like behaviours. Create hair, props that bounce, ropes, chains and more with ease. It builds on the physics maths in this package.
• 🧲 Force Fields: Radial fields with a falloff curve, directional fields, and global fields, in 3D and 2D
• ⚙️ Force Effects: Attract, Repulse, Tractor, Gravity, Suspend and Wind, ready to use as assets, plus a base class for your own
• 📥 Force Receivers: Make any Rigidbody feel the fields around it, with a sensitivity and an ignore list
• 📦 Physics Data: Convex hull, volume, area, cross section in any direction and centre of volume
• ➰ Constant Velocity: Hold a Rigidbody at a velocity or a spin
• 🧮 Math Library: Intercept, drag, force and torque to reach a velocity or direction, Verlet steps, geometry and polynomial solvers
• 🔷 Mesh Tools: Convex hulls, area and volume of meshes, from meshes, filters and colliders
• 🕹️ Example Scenes: Force fields, spherical gravity and multi-body gravity scenes, plus a legacy buoyancy scene, working with the Input System and the legacy Input Manager
• 📚 Knowledge Base: Guides and articles that explain the ideas as well as the API
• 💬 Live Discord Support: Direct help from the Heathen team and a community of fellow developers

REQUIREMENTS:

• Unity 6.0 or newer
• The free Heathen Game Framework, which Heathen Toolbox installs for you
• Mathematics and Burst, which Unity installs for you

Looking for Ballistics or Verlet Motion? They are separate Toolkit packages. Verlet Motion builds on this one.
