Hello everyone, i'm new to processing and have been learning for about 4 days now. I am trying to make my first game (pretty low quality) , the basic idea is that the cursor moves around a picture while a red dot bounces around the screen. the red dot is meant to be the laser sight of a sniper, and your goal is to try not to get hit. I was wondering how i can make it so whenever the dot goes over the picture, a sound is triggered, the screen flashes red, and a blood splatter appears and fades away where the picture was "shot". it would be very helpful is someone send a couple links explaining, or explain it yourself if you would like. Just having the code i am looking for by itself wouldn't be very helpful. Also here is the code i am working on below.
