Coding tutorial: Object pool pattern
Learn how to code the object pool pattern by pre-allocating memory and reusing objects. Which can greatly improve performance when reusing short lived objects like bullets and particles.

Observer Pattern Graphical Demo
This tutorial shows a graphical demo of the observer pattern. The circle, square and mosaic background are all observers of the button press. Whilst the owner of the button is the subject.

Expanding circle columns made in Processing
Made these expanding circle columns in Processing by rendering three circles without clearing the screen, and using hue shifting to keep it interesting. The colours go from dark and saturated, to bright and desaturated.

Rabbit and Carrot Finite State Machine
This post shows how the behaviour of a rabbit can be coded using a finite state machine, by breaking down the rabbit’s behaviour into different states. The rabbit’s goal is to wander around and eat carrots, whilst avoiding the deadly mouse cursor!

Coding a bouncing slime in Processing
Learn how to code a bouncing slime using forces and the finite state machine pattern. You will learn how to split your code up into an air state and a ground state. In the ground state the slime will wait, then launch into the air state using an impulse force. In the air state the…
