shooting straight

magnia

I am making a 2d racing. The cars have guns but they only shoot straight when its facing right can anyone tell me whats wrong with my code.

public ShotEntity(Game game,String sprite,int x,int y)
{
super(sprite,x,y);

this.game = game;

dx = moveSpeed;
}

public void tryToFire()
{
// check that we have waiting long enough to fire
if (System.currentTimeMillis() - lastFire < firingInterval)
{
return;
}

// if we waited long enough, create the shot entity, and record the time.
lastFire = System.currentTimeMillis();
ShotEntity shot = new ShotEntity(this,"sprites/shot.gif",car.getX(),car.getY()+10);//this sets where shot goes from
entities.add(shot);
}

What does the inherited ShotEntity() do?

it just gives u the initial position, displays the pic and removes it if it leaves the screen u any idea how to get it to shoot in the position the car is facing

What happens when ya call this method: entities.add(shot)

Sounds like in the add method or somewhere along the line, it takes the jpeg and steps it along the x axis, so no mather which way ya face it will shoot right.
Do you store the heading of the car ?
based on heading you'll have to step the shots jpeg's x and y values.
ie x+step for East, x-step for West, y+step for north etc.
