我的角色因碰撞而消失。游戏

Question

自从我第一次尝试编写代码以来，我就遇到了这个问题，我的问题在于此类内部的碰撞系统。

def updates(self, wall):
        self.hero = hero
        self.wall = wall
        self.rect.x += self.change_x

        list_of_collisions = pygame.sprite.spritecollide(self, self.wall, False)
        for wall in list_of_collision:
            if self.change_x > 0:
                self.rect.right = wall.rect.left
            elif self.change_x < 0:
                self.rect.right = pared.rect.left

        self.rect.y += self.change_y
        list_of_collision = pygame.sprite.spritecollide(self, self.wall, False)
        for block in list_of_collision:
            if self.change_y > 0:
                self.rect.right = wall.rect.left
            else:
                self.rect.left = wall.rect.right 

出于某种奇怪的原因，我的角色完美地与一堵墙相撞，但在其他墙上消失了。我试图自己解决它，我不会问我是否没有尝试过我想到的一切。

这是完整的代码（抱歉有点长）

#imports

        for block in list_of_collisions:
            if self.change_y > 0:
                self.rect.right = wall.rect.left

                self.rect.left = wall.rect.right

        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                Aaron.velocity (-10, 0)
            elif event.key == pygame.K_RIGHT:
                Aaron.velocity (10, 0)
                print(Aaron.cambio_x, Aaron.rect.x)
            elif event.key == pygame.K_DOWN:

    x = Aaron.rect.y
    y = Aaron.rect.x
    cam_x = Aaron.change_x
    cam_y = Aaron.change_y
    print("[",x,"*",y,"-","]", "[" ,cam_x,"^", cam_y,"&","]")
    Aaron.update(list_walls)


    #mouse for touching ( not in used yet)
    pos = pygame.mouse.get_pos()
    royx = pos[0]
    royy = pos[1]




#Draw
    screen.fill(WHITE)
    list_of_lists.draw(screen)

 #FInal ditails
    clock.tick(20)
    pygame.display.flip()
pygame.quit()

如果您注意到，我还尝试打印变量 x、y、cam_x、cam_y，这就是控制台显示的内容。当我按下右键时，值 0、200 才会出现。

[ 300 * 200 - ] [ 0 ^ 0 & ]
[ 300 * 150 - ] [ 0 ^ 0 & ]
[ 300 * 150 - ] [ 0 ^ 0 & ]
[ 300 * 150 - ] [ 0 ^ 0 & ]
[ 300 * 150 - ] [ 0 ^ 0 & ]
0 200

从此更改您的代码

for block in list_of_collision:
            if self.change_y > 0:
                self.rect.right = wall.rect.left
            else:
                self.rect.left = wall.rect.right 

到这里

for block in list_of_collision:
                if self.change_y > 0:
                    self.rect.bottom = wall.rect.top
                elif :
                    self.rect.top = wall.rect.bottom

您正在设置框的右侧和左侧，而您应该设置顶部和底部
