This package contains everything you need to take control of Physics in your games and simulations.

Developer Website

N-Physics is made of Runtime behaviours and Editor tools to ;
- Better understand what's happening under the hood.
- Easily experiment with Physics features such as AddForce and ForceModes, and let the players interact with Rigidbodies, without the need to code.
- Edit Rigidbodies' hidden properties, such as their center of mass and inertia tensors, to control their behaviour.
- Better control Rigidbodies' Air Resistance with custom Drag behaviours.
- Add medium/bodies relationships, so that Rigidbodies slow down when entering a given medium such as water.
- Add custom forces, such as Magnetic Force.
- Set Gravity per scene, and let player control it at runtime.
- Easily control Physics driven objects using inputs.
- Easily switch Rag-dolls from/to Animated State, and make their limbs inherit inertia from their animations.

Main Features

Physics Simulation
Allows taking control over Physics Simulation (Hold, Run, Pause, Restart).

Point Click Force
Uses Mouse Position or Transform's Forward vector to RayCast in the scene, and Adds Force, Force At Position, Explosion Force, with UI controls for Runtime adjustments.

Gravity Controls
Allows setting G vector per scene and adjust Gravity direction and strength with UI sliders.

Gravity Vector
Allows controlling Gravity with a GameObject.

Medium Drag Modifier
Allows changing a Rigidbody's Drag and Angular Drag values when it enters and exits a Trigger Collider, to simulate an object entering a different medium such as vacuum, air, water...

Directional Drag
Allows setting a Rigidbody's Drag coefficient per local axis, resulting in more realistic behaviour of planing objects.

Center of Mass Position
Allows changing a Rigidbody's Center of Mass position, for simulating uneven density objects.

Inertia Tensor Override
Allows changing a Rigidbody's Inertia Tensor Rotation and Strength per axis, to control axes the object turn about and how easy they spin.

Initial Velocity
Allows changing a Rigidbody's Velocity and Angular Velocity, to animate them upon start.

Magnetic Force
Allows Rigidbodies attracting each other, with parameters for more or less realistic behaviour.

Helpers
Comes with many other helper tools and components, such as Rigidbodies Inspector, Speed-O-Meter, Ragdoll Switch, SpringJoint Renderer.

Prefabs.
Ready for drag 'n' drop in your scenes.

Samples Scenes
Illustrating major features.

Programmers and Artists friendly
Unity Events and UI components allow artists to use components with no coding. Clean C# allow programmers to easily customise.
