I am making a game where you are a space ship and there are other space ships that shoot lasers at you. I want the enemies to be able to shoot a laser by making a new laser object and when it reaches the end of he screen or hits its target it does its damage and gets removed from memory (lasers will be in an arraylist because there are multiple types of lasers). I want each laser to be stored in its parent classes array list but i don't know much about parents and childs in programming. I couldn't find a good tutorial anywhere on the processing website either. Can anyone tell me how to use parents and such, or think of a better way to shoot lasers?

I am making a 3D program, where you use the mouse to look around and the code for my camera movement is:

Is there a way to re-size an image in processing without it blurring it? I'm too lazy to re-size all my textures in GIMP, and was wondering if there is a way to do this. I want large 8-bit isometric textures, and they are all 16*8 right now, i want them to be 64*32, but still 8-bit.
