shooting laser problem

I want to shoot a laser from my player, from the bottom to the top. I have the laser shooting upwards, but the problem is that if i hold down the mouse button the laser stays on, i want it to shoot to the top, and go away until you click again. If anyone could help me solve this problem i would appreciate it. This is for a game so it could be used to cheat in a way. This is the code i have

class Shoot
{
boolean shoot = false;
Shoot()
{
}
void shoot()
{
if (mousePressed == true)
{
shoot = true;
}
if(shoot==true)
{
laserdetail();
shoot = false;
}
}
void mousePressed()
{
shoot = true;
}
void laserdetail()
{
stroke(0,255,0);
strokeWeight(5);
line(mouseX, 680, mouseX, 0);
}
}

AFAIK mousePressed() (the function) should not be inside your class. Any way the field and the function have different behaviour. The field is true while mouse is pressed, the function is called once only, see:

void draw(){
if(mousePressed)
println("field = true");
else
println("field = false");
delay(500);
}
void mousePressed(){
println("call back function");
}

this seams to work as you want:

Shoot s = new Shoot();
void draw() {
background(0);
s.shoot();
}
void mousePressed()
{
s.shoot = true;
}
class Shoot
{
boolean shoot = false;
float a=680;
Shoot()
{
}
void shoot()
{
if (shoot)
{
laserdetail();
shoot = false;
}
}
void laserdetail()
{
stroke(0, 255, 0);
strokeWeight(5);
line(mouseX, 680, mouseX, 0);
}
}
