            self.dy=5
        else:
            self.shootCount+=1


    def update(self):

        self.rect.center=(self.rect.centerx,self.rect.centery)
        if self.rect.top<=0:
            self.kill()


def main():
    image=pygame.image.load('geometrybullet.png').convert()
    plane=Plane()
    allSprites=pygame.sprite.Group(plane)
    clock=pygame.time.Clock()

    while 1:
        pressed=pygame.key.get_pressed()
        for i in pygame.event.get():
            if i.type==QUIT or pressed[K_q]:
                exit()
*        if  pressed[K_SPACE]:*
*                bullet=Bullet(plane.rect.centerx,plane.rect.centery,image)*
*                bullet.shootCount=0*
*                allSprites.add(bullet)*


        allSprites.clear(screen,background)
        allSprites.update()
        allSprites.draw(screen)
        pygame.display.flip()


if __name__=='__main__':
    main()


I was trying to make shooting game. whenever I press the space key bullet
object is called (bold code) . I want delay between iterations to produce
the gap between the bullets.Tried the time.wait() but its working. Any
Ideas??

Thanks In Advance
