beta exhibition & some quests. 8bit game

in Programming Questions  •  1 year ago  


Is a defender game searching for information against twitter. It search active  for tweets containing keywords like 2012 and search in those results after END n such. It converts tweets into comets that spawns randomly outside the sketch, aimin at the center..
 Your job as starfleet captain commander Buck is to save the earthlings against confusion AND mass destruction.
Achieve this by crashing your spaceship into every comet possible...


It's working but need som few tweaks and a mutch cleaner code.

1: 
How do I make the comets "lag" their way towards earth? 
(as In  old 8 bit "grid"-games and as in;" low frame rate", like the movement of the spaceship in this sketch)
Can i fake it in some kind of way?

2:
 Please look it thru and se if you find any superbig mistakes (exept the "press H for help"- loop, that's under construction).

    The loadFile and loadImage calls in collision() are going to be relatively slow. You better load them in setup() as well. A class can access global static data.
    size(height = 1000, width = 500); is superfluous: Processing sets these variables itself, user shouldn't mess with them. And size() should be the first instruction of setup(). I don't know if that's still the case, but at some time, instructions before size() were executed twice...
    A Tweeter request every 5s is a bit too much by Tweeter standards, I think...
