Boomerang implementing logic

[nilamo]

What about this?

def update(self):
    direction = +1
    if self.game.player.weapon == 'boomerang':
        now = pg.time.get_ticks()
        if now - self.last >= self.cooldown:
            direction = -1
    self.pos += self.vel * self.game.dt * direction
    self.rect.center = self.pos
