Processing is a Java-based wrapping development environment that allows for quick and easy coding for graphical and user-interface designs.

// It's a convention to declare variables at the top,
// and variables must be declared outside of the setup
// and draw functions? classes?

int j = 0;
int c = 0;
int cx = (255-c);

void setup(){
 size(800,600);
 frameRate(120);
 background(255, 11);
}

void draw(){

 if(mousePressed)  {
 stroke(mouseX % 255);
 strokeWeight(abs(pmouseX-mouseX));    
 line(pmouseX, pmouseY, mouseX, mouseY);
 }
 // if (keyPressed == true) save("filename" +j+".png");
}
void keyReleased(){
 if (key == 's') {
 ++j;
 save("filename"+j+".jpg");
 }
 // the ' ' indicates (maps) the spacebar to this event
 if (key == ' '){
 fill(c);
 c = round(random(0-255));
 println(c);
 cx = (255-c);
 println(cx);
 noStroke();
 rect(0,0,width, height);  
 stroke(cx);
 }
}

void drawGreenRect() {
 fill(0,255,0);
 noStroke();
 rect(30,30, width-60, height);
 stroke(0);
}

//void mouseReleased(){
//  ++j;
//  save("filename"+j+".png");
//}
