Mocha2007 / gravity

Gravity Simulator and Visualizer, several modes

hex.py

Simple file writer, accepts numbers in binary, octal, hex, decimal.

Format:

• bX - X_2
• oX - X_8
• dX - X_10
• xX - X_16

koipond.py

Gravity Simulator. Editable infile are four options:

• party - Activate party mode (gravitational effects reversed)
• pond - Fish theme
• wall - Toggles wall preventing objects from leaving screen
• gay - Surprise

mokitools.py

A helper for those manually writing 2-bit mokifiles.

• w - 11
• s - 10
• g - 01
• b - 00

Output is decimal.

Width, Height

Big-endian. In pixels. Maximum 65,535.

Layers

Number of layers, for image editing and 3-D imagery. Maximum 255.

Speed

4 times the FPS. Minimum 0.25 hz, maximum 64 hz.

Frames

For video. Maximum 16,777,215 (18,641 hours of video at 1/4 hz, 78 hours of video at 60 hz.).

Image Start

Byte where the image starts. Normally 0x10, but may be postponed to include metadata or palette information.

Notes

• 0x0000 under Width, Height, Layers, and Frames is treated as 0x0001.
• Theoretical maximum filesize is 73496498551345642516 bytes (73.5 EB), of which 73496498551345642500 bytes is the image data. (65535x65535x255x16777215 px 32-bit color)
• Currently, Frames and Layers are unimplemented.
