Shooting bullets with cocos2d and sneakyjostick (math)

Question

My Code:

    -(void)ShootingWithJoystick {

     if (_nextProjectile != nil) return;


CGPoint location = CGPointMake(rightJoystick.velocity.x,rightJoystick.velocity.y);  


        // Set up initial location of projectile
        _nextProjectile = [[CCSprite spriteWithFile:@"player.png"] retain];
     _nextProjectile.scale = 0.2f;
     _nextProjectile.position = player.position;

        // Determine the angle to rotate
        CGPoint shootVector = ccpSub(location, player.position);


      // Move projectile offscreen
ccTime delta = 1.0f;
CGPoint normalizedShootVector = ccpNormalize(shootVector);
CGPoint overshotVector = ccpMult(normalizedShootVector, 420);

[_nextProjectile runAction:[CCSequence actions:
                            [CCMoveBy actionWithDuration:delta position:overshotVector],
                            [CCCallFuncN actionWithTarget:self selector:@selector(spriteMoveFinished:)],
                            nil]];


 // Actually set up the actions
[player runAction:[CCSequence actions:
                   [CCCallFunc actionWithTarget:self selector:@selector(finishShoot)],
                   nil]];





// Add to projectiles array
_nextProjectile.tag = 2;


    }
    - (void)finishShoot {

        // Ok to add now - we've finished rotation!
        [self addChild:_nextProjectile];
        [_projectiles addObject:_nextProjectile];

        // Release
        [_nextProjectile release];
        _nextProjectile = nil;
     NSLog(@"finishShoot");
    }

    -(void)spriteMoveFinished:(id)sender {
     CCSprite *sprite = (CCSprite *)sender;
     [self removeChild:sprite cleanup:YES];


     if (sprite.tag == 2) { // projectile
      NSLog(@"spriteMoveFinsished");
      [_projectiles removeObject:sprite];
     }


}

The ShootingwithJoystick method is very time call when my rightJoystick is active. My leftJoystick moves the player and the rightjoystick rotates the player and shoots in that direction but when i test it the bullet just goes in only one direction (bottom left corner) and if i want to shoot up it shoot still in the bottom left corner

Can you help me please?
