在我的密室逃脱游戏中，我无法显示其中一个钥匙

Question

所以基本上我正在制作一个逃生室游戏。在游戏中，你必须与桌子互动，一把钥匙就会出现在地图上。然后你会和钥匙互动，把它捡起来，它会放在你的头顶上，你可以自由地把它带到任何地方逃离逃生室。现在我遇到的问题是，我能够与桌子互动，而碰撞是有效的。但密钥不会产生。

这是我的代码：

import pygame
from pygame.locals import *
pygame.init()
screen = pygame.display.set_mode((600,600))
#VARIABLES
velocity = 1
yellow = (255,255,0)
clock = pygame.time.Clock()
white = (255,255,255)
blue = (0,0,255)
black = (0,0,0)
brown = (110,38,14)
x = 300
y = 300
#VARIABLES
while True:
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
exit()  
def Room():
global Player
global x
global y
screen.fill(black)
Player = pygame.draw.rect(screen,blue,(x,y,50,50))
wall_1 = pygame.draw.rect(screen,white,(10,50,20,500))
wall_2 = pygame.draw.rect(screen,white,(10,30,580,20))
wall_3 = pygame.draw.rect(screen,white,(570,40,20,520))
wall_4 = pygame.draw.rect(screen,white,(10,540,580,20))
if Player.colliderect(wall_1):
x = x + 70
if Player.colliderect(wall_2):
y = y + 70
if Player.colliderect(wall_3):
x = x - 70
if Player.colliderect(wall_4):
y = y - 70
def Movement():
global velocity
global x
global y
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT or event.key == ord('a'):
x = x - velocity
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_RIGHT or event.key == ord('d'):
x = x + velocity
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_UP or event.key == ord('w'):
y = y - velocity
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_DOWN or event.key == ord('s'):
y = y + velocity
def Text():
font = pygame.font.Font("freesansbold.ttf",15)
interact = font.render("E To Interact!",True, (255,255,255))
screen.blit(interact,(75,275))
def FirstKey():
global Player
global x
global y
KeyX = 300
KeyY = 400
key = pygame.draw.rect(screen,yellow,(KeyX,KeyY,15,15))
if Player.colliderect(key) == True:
if key[K_e]:
KeyX = x
KeyY = y - 35
def Desk():
global x
global velocity
Desk = pygame.draw.rect(screen,brown,(75,300,20,60))
if Player.colliderect(Desk) == True:
velocity = 0
Text()
keys = pygame.key.get_pressed()
if keys[K_e]:
x = 300
velocity = 1
FirstKey()
else:
None


#Function Calls#
Room()
Movement()
Desk()
#Function Calls#
pygame.display.update()
#FPS#
clock.tick(120)
#FPS#

我希望你能给我一个答案，并解释我做错了什么。附言：我使用的是最新版本的Python(3.10.5(和Pygame模块。

尝试将事物封装在一个类中，与其像游戏中那样安全地调用函数，不如将函数分解为它们需要做的事情，并在每个周期调用它们。所以你需要检查输入，检查冲突，检查库存，检查状态，绘制对象，等等
