introduction

hello, this is my 2D gravity and space simulator. written in python and pyray

usage

• clone the code

  git clone https://github.com/9EED/2D-gravity/

• install dependencies

  pip install pyray

• run the code

  python3 2D-gravity.py

controlls

[tab] switch modes settings, drawing, deleting, orbits and statistics
[up][down] select a setting
[left][right] change the selected setting
[mouse left]+[drag] pan around
[mouse scroll] zoom in and out
[space] pause and unpause

settings

here you can change the basic simulation rules

• walls: turn on and off the worlds boundries
• walls x, walls y: change the width and height of the boundries
• merge: turn on and off the planets merging on collision to form a new one
• bounce: turn on and off wether planets bounce or stick on collision
• gravity: change the effect of gravity between bodies

drawing

here you can make new planets and change their settings

• size: how big the body is
• density: how much mass the drawn body has, changes how much it attracts other bodies
• static: static planets do not move, but attract others
• random: randomizes the new planet

deleting

in this section you can delete unwanted bodies

• delete: click to delete one by one
• delete all: delets all bodies upon click

statistics:

general information about the simulation world

• planets: how many are there in the world
• velocity: sum velocity of all bodies
• mass: sum mass of all bodies

#orbiter a tool to make planets orbit each other(still a work in progress)

• select orbited
• select orbiter
• make orbit

camera

change the camera settings

• follow: allows you to select a planet and follow it
• release: releases the camera controlls
