Games from Nothing: Black & White Exercise #4 — Blip


Blip is the particle game that I’ve been working on. It features a  cloud of generated circles that change color based on mouseX and mouseY positions and slowly move towards the cursor’s direction while the mouse is pressed.

A stream of particles immediately latches onto the mouse’s position as the cloud drags itself along the screen. When the mouse is let go, the particles from the cloud to the mouse fall off of the screen due to gravity, and the cloud remains at a stable x/y position.


I enjoyed coding blip because it taught me about particle generation and gave me new ideas for visual effects for my games. It seems daunting to keep track of everything in an array, but if I can do that, then I can make full use of each particle, in terms of collision checking.
