draw function and background

Ok, I have a feeling the solution to my problem is going to be a lot easier than I think it is, but I am new to programming and was wondering if someone would be kind enough to help me through my confusion.

Here's a basic idea of my problem. I would like the lines in this program to behave the same way they do right now, while also being able to utilize the background function that's commented out.

int newStroke = 1;
int x = 100;
void setup () {
size (400, 400);
background (255);
frameRate (15);
smooth ();
}
void draw () {
//background (255);
line (x, 100, x - 30, 300);
x += 10;
if (x > 300) {
x = 100;
strokeWeight (newStroke ++);
}
if (newStroke >= 13) {
noLoop ();
}
}

I don't necessarily need the background function for this program, but it's become more about me understanding the problem (conceptually) than anything.

int newStroke = 1;

int lineCount = 0;

int x = 100;

int lastTime = 0;

void setup () {

size (400, 400);

background (255);

// frameRate (15);

smooth ();

}

void draw () {

background (128+random(20));

if ( newStroke > 1) {

strokeWeight( newStroke -1);

for ( x = 100; x <=300; x+=10) {

line(x, 100, x-30, 300);

}

strokeWeight( newStroke );

}

for ( x = 100; x <=100 + (10*lineCount); x+=10) {

line (x, 100, x - 30, 300);

}

if (lineCount == 20) {

lineCount = 0;

strokeWeight (newStroke ++);

if (newStroke >= 13) {

noLoop ();

}

if( millis() - lastTime > 1000/15){

lastTime = millis();

lineCount++;

}
