I am trying to make basketball game in which player tries to score as many balls into net. The player starts with 3 in upper left hand corner with a ball showing indicating that if he misses a shot, 2 will then show up, another shot missed would mean it would go down to 2 and then another shot missed would mean it would go down to 1 showing up in upper left hand corner until reaches 0. How all would you guys recommend me going about setting this health part of my game up?
