Hi, sorry for this newbie question. But if you help me out i will be very happy.
Im just starting out with processing, and i want to build a game prototype (just to learn) but right when i started i found myself in a situation
Here is the code (simple)
// size of the application (pixels)
int appWidth = 400;
int appHeight = 525;
// size of the ship (pixels)
int shipWidth = 60;
int shipHeight = 62;
// initial position of the ship
int shipInitX = 170;
int shipInitY = 462;
// properties
BImage sprites;
void setup()
{
size( appWidth, appHeight );
sprites = new BImage();
sprites = loadImage( "ship01.gif" );
}
void loop()
{
image( sprites, shipInitX, shipInitY );
}
it seems that loop is creating a lot of images (and fucking up the program) instead of updating the one that already extits... if i move the image upwards, it looks like a lot of images are behind one pixel 
i may have to clear out everything and create again ? if so, how could i do that ?
help me out

read cello's explanation of how to think about the "drawing-area" and loop() here. look for chalkboard ...
the images you see are the images you've drawn (in the loops) before. you need to do the "updating" yourself by (for example) using background().
