I have studying processing for 1 month. I would like to make a shooting game .When I run the program and shot the fire, the fire I shot recently will stay in the original place.
When the enemy passes where I once l, they die automatically without pressing the shooting key ( 'c' || 'C').
I am confuesd with this problem two days long!Hope anyone can answer my question. Thank you!
