如何查看是否不碰撞

Question

我想看看我的车是不是碰撞rect。我的车在路上，我不想让它熄火。所以我想让电脑检测汽车是否在路上，有点像colliderect（）函数，但相反。这是我的代码：我的错误愚蠢QUESTIN !!!!!!!!

import pygame  
from pygame.locals import * 
pygame.init() 

#define variables 
width, height = 940, 780 
screen = pygame.display.set_mode((width, height)) 
grey = 87, 87, 87 
white = 255, 255, 255 
player = pygame.image.load("Pics\goodcar.jpeg") 
keys = [False, False, False, False, False] 
playerpos = [0,40] 
green = 0,255,0 
red = 255,0,0 
color = red 

x1 = 0 
x2 = 40 
y1 = 940 
y2 = 100 




#main program 

while 1: 

    screen.fill(0) 
    road = pygame.draw.rect(screen, grey, (x1,x2,y1,y2), 0) 
    traffic_light = pygame.draw.circle(screen, color, (640,90), 40, 0) 


    screen.blit(player, playerpos) 



    car_rect = player.get_rect(left=playerpos[0], top=playerpos[1]) 






    for event in pygame.event.get(): 
     if event.type==pygame.QUIT: 
      pygame.quit() 
      exit(0) 

     if event.type == pygame.KEYDOWN: 
      if event.key==K_RIGHT: 
       keys[0]=True 
      if event.key==K_LEFT: 
       keys[1]=True 
      if event.key==K_DOWN: 
       keys[2]=True 
      if event.key==K_UP: 
       keys[3]=True 
      if event.key==K_SPACE: 
       keys[4]=True 



     if event.type == pygame.KEYUP: 
      if event.key==pygame.K_RIGHT: 
       keys[0]=False 
      if event.key==pygame.K_LEFT: 
       keys[1]=False 
      if event.key==pygame.K_DOWN: 
       keys[2]=False 
      if event.key==pygame.K_UP: 
       keys[3]=False 
      if event.key==pygame.K_SPACE: 
       keys[4]=False 

    if traffic_light.colliderect(car_rect): 
     if color == red: 
      keys[0]=False 
    if car_rect == 100: 
     keys[2]=False 


    if keys[0]==True: 
     playerpos[0]+=2 
    if keys[1]==True: 
     playerpos[0]-=2 
    if keys[2]==True: 
     playerpos[1]+=2 
    if keys[3]==True: 
     playerpos[1]-=2 


    if keys[4]==True: 
     if color==red: 
      color = green 
     else: 
      color = red 
    pygame.display.update() 

感谢您在前面的帮助！

可以使用not语句来完成的colliderect相反：

if not thing1.colliderect(thing2): 
    ....
