# gravity-sim

## Superseded by https://github.com/mkhan45/gravity-sim-v2

N body gravity sim with rust and `ggez`, made to learn rust

Initially written with OOP, made a new version with `specs` that runs about 20% better on my desktop PC, but slightly worse on my laptop. Maybe because it parallelizes a lot more?

Web port made with quicksilver, lots of features missing:

## Controls

Arrow keys to move

Scroll to zoom in/out

Q/A to increase/decrease radius of next placed body

W/S to increase/decrease density (try making it negative)

E/D to increase/decrease trail length (removing trails increases performance by a lot)

X/Z to increase/decrease prediction speed, setting it to 0 turns of predictions.

Left click to place a body, dragging before releasing makes an initial velocity vector.

Right click over a body to delete it.

G creates a 10x10 grid of bodies with the specified radii and densities.

R to reset.
