For this I wanted to create an effect of a scene from the matrix movie. The goal was to simulate an event horizon as you enter the matrix. To do so there was a need to create an array list to get, set, and add new values to replicate particles moving in certain directions to show a navigation effect on keyPressed. The most trouble I had was mapping functions for the mouse movements and FOR loops for the navigation to get the effect to work. I spent a lot of time in the tutoring center trying to understand the coding I was trying to do and in the end I ended up brute forcing my way to making the code work with the help of a tutor.
