Hey guys I'm pretty new to processing. I've been trying to get falling balls working for a few days now. I have ALMOST everything where I want. But not quite. When you lose, I want my timer to reset and start new when you click play again. Suggestions?

Here is my source code.

int gamestate = 1; //gamestate 1 = menu, gamestate 2 = difficulty menu, gamestate 3 = instructions, gamestate 4= game running, gamestate 5 = gameover

int time;

int nBalls = 40;

float [] ySpeed = new float [nBalls];

float [] xBall= new float [nBalls];

float [] yDir= new float [nBalls];

float [] yBall= new float [nBalls];

float [] sizes = new float [nBalls];

color [] colors = new color [nBalls];

float xBlock=100;

float boost=0;

float diff;

float speed;

float easy=40;

float medium=80;

float hard=100;

float eSpeed=0;

float mSpeed=20;

float hSpeed=40;

void setup() {

size(1000, 1000);

initBalls();

}

void draw () {

background(0);

if (gamestate == 1) {

menu();

if (mouseX> 255 && mouseX< 755 && mouseY > 200 && mouseY < 300 && mousePressed) {

gamestate = 2;

time=0;

}

if (mouseX>255 && mouseX< 755 && mouseY > 400 && mouseY < 500 && mousePressed) {

gamestate = 3;

}

}

else if (gamestate == 3) {

instructions();

if (mouseButton== RIGHT) {

gamestate = 1;

}

}

else if (gamestate == 2) {

difficulty();

if (mouseX> 255 && mouseX < 755 && mouseY > 300 && mouseY< 400 && mousePressed) {

gamestate = 4;

diff=easy;

speed=eSpeed;

}

if (mouseX> 255 && mouseX < 755 && mouseY > 500 && mouseY< 600 && mousePressed) {

gamestate = 4;

diff=medium;

speed=mSpeed;

}

if (mouseX> 255 && mouseX < 755 && mouseY > 700 && mouseY< 800 && mousePressed) {

gamestate = 4;

diff=hard;

speed=hSpeed;

}

}

else if (gamestate== 4) {

drawBalls();

moveBalls();

character();

bounceBalls();

timer();

}

else if (gamestate == 5) {

gameOver();

if (mouseX>0 && mouseX<300 && mouseY> height -100 && mouseY<height &&mousePressed) {

gamestate =2 ;

}

}
