Bacteria , Random Walks, and Food

This program is a rough simulation of bacteria's habits using random walks. The circles are bacteria while the beige squares that appear are food particles.

Bacteria are biased to walk towards these food particles. Bacteria are also biased to walk towards the mouse when it is clicked to create a target. However, bacteria will ignore the mouse when there is already food onscreen. Food spawns every few seconds.

Press A to re-randomize the positions of the bacteria onscreen.
