MaartenGr / Sprite-Generator

Python procedural sprite generator

Sprite Generator

A python port of https://github.com/zfedoran/pixel-sprite-generator. It essentially takes in any template and randomly generates sprites based on the template.

Algorithm

The sprites are generated by using a two dimensional mask. The values in the mask are then randomized and mirrored. The resulting template is rendered to a canvas element.

The algorithm is explained in more detail on Dave Bollinger's website.

Examples

Spaceships

Robots

Dragons

Dragons Top-Down

from SpriteGenerator import generate_canvas

robot = [[0, 0, 0, 0],

         [0, 0, 1, 2],
         [0, 0, 0, 2],
         [1, 1, 1, 2],
         [0, 1, 1, 2],

         [0, 1, 2, 2],
         [1, 1, 0, 0]]
