hi I have a problem, my character sprite shoots to the right, but when the sprite turns around, i cant figure out how to make the shot go left.

+ Code Snippet

dbCreateAnimatedSprite ( 5, "nova.png", 1, 1, 5 );
	dbPlaySprite ( 5, 1, 1, 0 );

	if ( blnAmmo )
	{
		ammoX += 14;
		dbSprite ( 5, ammoX, mY - 77, 5 );

		//reset blnAmmo variable
		if ( ammoX > 650 || ammoX < 0 )
		{
			dbDeleteSprite ( 5 );
			blnAmmo = false;
		}
	}

	if ( CheckFire() == true && blnAmmo == false )
	{
		blnAmmo = true;
		ammoX = (mX + 5);
		//playerCheckHitEnemies();
		dbSprite ( 5, ammoX++, mY - 77, 5 );
	}
	else if ( CheckFire() == true && blnAmmo == false && dbSpriteExist (2) )
	{
		blnAmmo = true;
		ammoX = (mX - 5);
		//playerCheckHitEnemies();
		dbSprite ( 5, ammoX--, mY - 77, 5 );
	}

halp.

ammoX += 14;

Here's your culprit!

When moving left, you subtract 5 from ammoX but then turn around and add 14 back to it during the next pass...

That's what it looks like to me.

So, near the top, add the following logic:

+ Code Snippet

  int ammo_adj = 14;
  if (facing_left) 
    ammo_adj = -14;

  dbCreateAnimatedSprite ( 5, "nova.png", 1, 1, 5 );
  dbPlaySprite ( 5, 1, 1, 0 );

  if ( blnAmmo )
  {
    ammoX += ammo_adj;
    dbSprite ( 5, ammoX, mY - 77, 5 );

    //reset blnAmmo variable
    if ( ammoX > 650 || ammoX < 0 )
    {
      dbDeleteSprite ( 5 );
      blnAmmo = false;
    }
  }

  if ( CheckFire() == true && blnAmmo == false )
  {
    blnAmmo = true;
    ammoX = (mX + 5);
    //playerCheckHitEnemies();
    dbSprite ( 5, ammoX++, mY - 77, 5 );
  }
  else if ( CheckFire() == true && blnAmmo == false && dbSpriteExist (2) )
  {
    blnAmmo = true;
    ammoX = (mX - 5);
    //playerCheckHitEnemies();
    dbSprite ( 5, ammoX--, mY - 77, 5 );
  }

Hope this helps,
