unity – Gravity Engine U3079

The Gravity Engine provides a complete toolkit for space game physics.

– Add stars, planets and spaceships interacting via gravity N-body simulation or “on-rails”

– Design tracks based on shapes, view their paths in the editor and in the scene

– Manually change tracks with clickable handles

– Transition/rail rendezvous from any track to any track

– Staged rocket engines

– Earth Atmosphere Model

– Solar System Builder: Add any object in the JPL database

– Use real world units (km/AU, kg)

– Full support for particles

– Highly accurate double precision physics with optional algorithm/Kepler evolution

– Control overall evolution speed, scaling and CPU usage

In-scene extensible command line console for development and debugging

– Change gravity to whatever force you design

No programming or math required.
