---问题底部的完整代码---
我的计划是增加我的屏幕上被NPC占用的区域，以使播放器完全无法进入。我尝试通过在代码的NPC类中执行此方法来实现此方法，其中将播放器的y位置与npc的“ self.y” /当前y位置进行比较：
class NPC(object):
def __init__(self, path, x, y):
self.image = pygame.image.load(path).convert_alpha()
self.x = x
self.y = y
self.width = self.image.get_width()
self.height = self.image.get_height()
self.hitbox = (self.x, self.y, self.width, self.height)
def spawn(self, surface):
surface.blit(self.image, (self.x, self.y))
self.hitbox = (self.x, self.y, self.width, self.height)
pygame.draw.rect(screen, (255, 255, 255), self.hitbox, 2)
def collide(self, x, y, width, height):
if self.y <= y <= self.y + self.height:
print("collide")
up = True
else:
up = False
print("not")
我知道我还没有正确完成代码，我只是添加了应该阻止玩家出于测试目的而立即退出的部分。
但是由于某种原因，碰撞边界位于屏幕的顶部（而NPC不在），我怀疑这是由于程序从屏幕顶部测量了npc的高度（即：npc精灵的高度为32像素，因此碰撞区域位于屏幕顶部的前32像素）
阻止播放器移动的代码（这是“向上”布尔值在类外部所指的）也无法正常工作-这是由于可能未返回值吗？

这是一个很好的WIP，因此，如果您在检查过程中碰巧发现其他任何东西，可以随时提出来。
