当pygame中的player_rect和door_rect接触时，我如何显示开门

如何解决当pygame中的player_rect和door_rect接触时，我如何显示开门

我想在关闭的门（门）的x和y坐标处显示打开的门图像，但是我不知道在这些情况下显示功能如何工作。抱歉，我的代码有点混乱，它是几种不同代码阶梯的混合。我的一些代码来自：https://pythonprogramming.altervista.org/platform-game-in-detail-part-1/?doing_wp_cron=1603309265.4902870655059814453125

解决方法

添加变量player_at_door并使用False对其进行初始化。当玩家在门口时，设置变量True：

player_at_door = False

def check_collision(door,player):
    global player_at_door

    player_at_door = False
    for door_rect in door:
                
        if player_rect.colliderect(door_rect):
            player_at_door = True

根据door的状态绘制open_door或player_at_door：

def tiles(map1):
    global tile,door,player,enemy,player_rect
    door_list.clear()
    for y,line in enumerate(map1):
        #counts lines
        for x,c in enumerate(line):
            #counts caracters
            if c == "w":
                #caracter is w
                screen.blit(tile,(x * 16.18,y * 15))
            if c == "d":
                
                door_image = open_door if player_at_door else door # <---
                rect = screen.blit(door_image,(x * 16.2,y * 15)) # <---
                
                door_list.append(rect)
            if c == "p":
                player_rect = screen.blit(player,player_location)
            if c == "e":
                screen.blit(enemy,(x * 16,y * 15))
