奇形怪状的穿墙虫，碰撞系统游戏

Question

def checkCollision(self):
        for entity in self.Entities:
            ox = entity.x
            oy = entity.y
            for block in self.Blocks:

                if block.y < entity.y and entity.y < block.y + block.size:
                    if (entity.x < block.x and block.x < entity.x+entity.width) or (entity.x+entity.width > block.x+block.size and block.x+block.size > entity.x):
                        print ("Hit Bottom")
                        entity.tpEntity(ox, oy+0.5)
                elif entity.y < block.y and block.y < entity.y+entity.height:
                    if (entity.x < block.x and block.x < entity.x+entity.width) or (entity.x+entity.width > block.x+block.size and block.x+block.size > entity.x):
                        print ("Hit Top")
                        entity.tpEntity(ox, oy-self.gravity)
                elif entity.x < block.x and block.x < entity.x+entity.width:
                    if (block.y < entity.y and entity.y < block.y + block.size) or (entity.y < block.y and block.y < entity.y+entity.height):
                        print("Hit Left")
                        entity.tpEntity(ox-0.5,oy)
                elif entity.x+entity.width > block.x+block.size and block.x+block.size > entity.x:
                    if (block.y < entity.y and entity.y < block.y + block.size) or (entity.y < block.y and block.y < entity.y+entity.height):
                        print("Hit Right")
                        entity.tpEntity(ox+0.5,oy)

我有一个奇怪的错误，如果我走到墙上，它总是注册它，好像它在上面。有人能向我解释一下为什么会发生这种情况吗?我应该如何解决这个问题？谢谢您:)

编辑: self.gravity变量是行星/地图上的重力，因为它在每个行星/地图上应该是不同的。默认情况下(此处)为0.2。

我假设实体和块是类？如果使用pygame.Rect对象设置每个对象，并在实体移动时对其进行更新，则可以通过以下操作简化此操作：

def checkCollision(self):
    for entity in self.Entities:
        ox = entity.x
        oy = entity.y
        for block in self.Blocks:
            if entity.rect.colliderect(block.rect):

然后测试x和y的位置来确定反射。
