为什么它没有价值观

所以，我正在创建一个太空入侵者游戏，我本应该在屏幕底部创建一个填充的红色方块，但这不会发生，因为我创建的类确实接受变量，但当我调用它时，错误表明它无法接受任何值。

我试着回忆课堂上的一切，但都没起作用。我原以为它会画一个正方形，但没有。这是我的代码

import pygame
import os
import time
import random
pygame.font.init()

WIDTH, HEIGHT = 750, 750
WIN = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("Space Invaders")

# Load Images
RED_SPACE_SHIP = pygame.image.load(os.path.join("assets", "pixel_ship_red_small.png"))
GREEN_SPACE_SHIP = pygame.image.load(os.path.join("assets", "pixel_ship_green_small.png"))
BLUE_SPACE_SHIP = pygame.image.load(os.path.join("assets", "pixel_ship_blue_small.png"))

# Player Ship
RED_SPACE_SHIP = pygame.image.load(os.path.join("assets", "pixel_ship_yellow.png"))

# Lasers
RED_LASER = pygame.image.load(os.path.join("assets", "pixel_laser_red.png"))
GREEN_LASER = pygame.image.load(os.path.join("assets", "pixel_laser_green.png"))
BLUE_LASER = pygame.image.load(os.path.join("assets", "pixel_laser_blue.png"))
YELLOW_LASER = pygame.image.load(os.path.join("assets", "pixel_laser_yellow.png"))

# Background
BG = pygame.transform.scale(pygame.image.load(os.path.join("assets", "background-black.png")), (WIDTH, HEIGHT))
#HERE IS THE CLASS WITH THE ERROR

class Ship:
    def _init_(self, x, y, health = 100):
        self.x = x
        self.y = y    
        self.health = health
        self.ship_img = None
        self.laser_img = None
        self.lasers = []
        self.cool_down_counter = 0

    def draw(self, window):
        pygame.draw.rect(window, (255,0,0), (self.x, self.y, 50, 50))x


def main():
    run = True
    FPS = 60
    level = 1
    lives = 5
    main_font = pygame.font.SysFont("comicsans", 50)
    
    #HERE IS WHERE I CALL THE CLASS AND GIVE IT VALUES
    ship = Ship(300, 650)
    
    clock = pygame.time.Clock()

    def redraw_window():
        WIN.blit(BG, (0,0))    
        #  draw text
        lives_label = main_font.render(f"Lives: {lives}", 1, (255,255,255))
        level_label = main_font.render(f"Level: {level}", 1, (255,255,255))

        WIN.blit(lives_label, (10, 10))
        WIN.blit(level_label,(WIDTH - level_label.get_width() - 10, 10))

        ship.draw(WIN)

    pygame.display.update()

    while run:
        clock.tick(FPS)
        redraw_window()

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

main（）

错误如下：
