Environment Simulation

Using logic, pixels are created to represent herbivores, omnivores and carnivores each represented with their own colour. Every so often a random amount of grass particles are spawned and if an entity doesn't eat after so long it dies and creates a meat particle in its place.
Carnivores - Spawned with tab key - Yellow colour
Omnivores - Spawned with Alt key - Purple colour
Herbivores - Spawned with Spacebar - Cyan Colour
Grass - Green colour Meat - Red colour
