Description

This software is made by JustinYD88 (cemetech.net). You may distribute this software, provided this notice is included. If the software has been edited in any way, please provide appropriate notice.

This program simulates gravitational interactions with m1*m2/d^2 and F=ma. The demo is included in the program, but you can make your own gravitational configurations by editing the [H] matrix and loading it with the 'LOAD [H]' option.

Matrices are used to represent the objects. Each row represents an object (up to 99, the matrix limit) and each column represents a property of that object.

Column 1: The mass of the object (negative masses work too)

Column 2: The current X-position of the object
Column 3: The current Y-position of the object

Column 4: The current X-velocity of the object
Column 5: The current Y-velocity of the object

Column 6: The previous X-position of the object (used for drawing lines, internal use)
Column 7: The previous Y-position of the object (used for drawing lines, internal use)

Column 8: If circle drawing is enabled, this is the radius of the circle. (If you leave 0, the radius will be (3*mass/4pi)^1/3).
Column 9: This is the colour used to render this object's circles and lines.

This program uses the [G] matrix for internal data manipulation, and the [H] matrix for importing configurations.

Included in the ZIP is the program file, one custom configuration, and two screenshots.
