Hi all, I'm trying to simulate a simple disease for a science project, however, I've run into a big problem. I've set up the disease so that when an object of the Organism class touches it, it turns green and is 'infected'. I'm trying to code this so that when an 'infected' object touches one that's 'uninfected', it in turn 'infects' the new object. However, using getOneIntersectingObject() is not working for some reason. Any ideas?
