Thread: shooting fire ball 2d

i trying to make my player shoot fire ball when ever it user hit space bar.

but the problem is that
i have 3 class
Main.java
Player.java
Shoot.java


----------------------Main.java
In my Main.java class i have run method where i am calling "PLaYER_SHOOT_MOVE" method from Shoot.java class

public void run()
while(true){
    shoot_class.PLAYER_SHOOT_MOVE(this, player_class, shoot_class);  //player shoot bullet moves
    }
}

than i am setting up method when user hit space it will run a method

[B]if(keys == KeyEvent.VK_SPACE){
   shoot_class.hitSHOOT(); 
}[/B]

--------------------------Shoot.java

private boolean hitSPACE = false;  //user hit space bar
private boolean dead = true;       //no bullet on screen (bullet is dead)

...

hitSHOOT method - which is getting called in Main.java
if user hit space bar than set hitSPACE to tru

public void hitSHOOT()  //user hit spacebar{
       hitSPACE = true;
}

move the bullet forward

public void PLAYER_SHOOT_MOVE(Main m, Player p, Shoot s){	
       x =  p.getX();
       y =  p.getY();
 
		if(hitSPACE == true)
		{
			x += dx;
		}	
}

//draw image if user hit spavebar and there are no bullet on screen

public void paint(Graphics g, Player p) 
	{
 
		if(hitSPACE == true && dead == true)
		{
			System.out.println(x);
			g.drawImage(this.getSIMAGE(), x, y, width, height, null); 
		}
	}

problem is that:
when i set space bar it show firball but it doesnt go forward.
i belive problem is in thiese statment

public void PLAYER_SHOOT_MOVE(Main m, Player p, Shoot s){	
       x =  p.getX();
       y =  p.getY();

i think i should some how move getX() at outside of method so it change x every time player move.

In addition to what Kevin said

public void run()
while(true){
shoot_class.PLAYER_SHOOT_MOVE(this, player_class, shoot_class); //player shoot bullet moves
}
}

if this is the loop that keeps the game in motion then, this method gets called, (over and over at as fast as the computer can, which is a bad idea):

public void PLAYER_SHOOT_MOVE(Main m, Player p, Shoot s){
x = p.getX();
y = p.getY();

if(hitSPACE == true)
{
x += dx;
}
}

I think am following what you are trying to show in these unorganized snippets. But it is difficult to follow. Next time just post the entire thing in order so it is much easier to follow.

public void PLAYER_SHOOT_MOVE(Main m, Player p, Shoot s){
x = p.getX();
y = p.getY();

Is x and y some global variable? What do they mean? Things like this make it hard, if not impossible, to help you, but with the whole code posted we can look at what we need to see. This is the reason why you should post a working example.
