В игре нужно добавить задержку между выстрелами

[Гамлет Варданян]

Подскажите пожалуйста как это можно сделать?

class Gun:

self.x = x

win.blit(weapon, (x, y))

self.x = x
self.y = y
self.radius = radius
self.color = color #Патроны
self.facing = facing
self.vel = 15 * facing
self.shotDelay = 60
self.timer = 0

def draw(self, win):
pygame.draw.circle(win, self.color, (self.x + 15, self.y + 15),self.radius)

for bullet in bullets:
bullet.draw(win)
if lastMove == 'right':
win.blit(weapon[0], (x + 7, y + 4))
elif lastMove == 'left':
win.blit(weapon[1], (x + 2 , y + 4))
pygame.display.update()
