Concentricity was my second attempt to utilize SpriteKit in XCode. It was developed after I thought of an interesting graphic for the menu screen, which can be viewed in the included video. Essentially, users entered a game where they chose how many rings and nodes per ring they wanted to solve. The objective of the level was to spin the rings until all the colors at their respective position mixed to create the colors in the center ring. One issue I found extremely difficult was color mixing; contrary to my belief prior to creating this game, conventionally mixing RGB or even CMYK values would result in “incorrect”combinations. As such, I ended up using a formula I found online that converted RGB mixing to conventional paint mixing (red plus blue equals purple). Beyond the included pictures, I worked on a version that utilized letters. This mode required users to spin the rings until words were created along each position. Although I never published the application I had a lot of fun working through the menu screen and accompanying levels.

Ribbit was the first app I worked on using SpriteKit. I created all of the graphics and animations (besides the background) in InkScape. The object of the game was to catch as many bugs as possible without three cross the screen. As time passed, the flies got faster and faster.
