我目前正在制作一个吃豆人游戏，正在努力弄清楚如何在与屏幕碰撞后从屏幕上移除一个 pelllet。我尝试将颜色更改为黑色，但我无法使其工作。接下来，我尝试del元素索引，但这也没有用。

我知道(而且我不太了解)的最简单方法是使用pygame.sprite.Group()和pygame.sprite.spritecollide。
这里的基本逻辑是，为颗粒创建一个精灵组，将每个颗粒创建为精灵并将其添加到组中。在游戏循环的每次迭代中，将精灵组绘制到屏幕上，并验证玩家角色与颗粒组中的任何颗粒之间是否存在冲突，spritecollide。
精灵碰撞有一个参数，用于在发生碰撞时消除颗粒，因此您希望将其设置为 true，以避免在下一个循环中绘制它。
#Basic logic as example.
pellets = pygame.sprite.Group()
#CREATE PELLETS AND ADD THEM TO THE pellets sprite group.
player = Sprite()
...
#IN THE GAME LOOP
#Validate if there was a collision.
pellets_hit = pygame.sprite.spritecollide(player, pellets, True) #True indicates that, if there were any hit, remove the pellet from the group.
if len(pellet_hit):
#Increment score or something.
...
#Updating the display
player.draw(screen)
pellets.draw(screen) #If there were any hit, the pellet won't be in this group and won't be drawn
这是一个使用精灵和精灵组的项目示例： 贪吃蛇游戏
经过大量工作我弄清楚了
#spawn pellets function
def spawnpellets(pointspawns):
abc=0
efg=0
px=0
py=-16
for row in pointspawns:
#y co ordinate
py=py+16
for n in row:
#x co ordinate
n=n-1
px=n*16
point=(pointclass(px, py))
#used to draw points
point.draw(screen)
if pygame.sprite.collide_rect(sprite, point):
tempfunc(pointspawns, row, n , py)
def tempfunc(pointspawns, row, n, py):
abc=n+1
efg=py/16
efg=int(efg)
tempindex=row.index(abc)
del pointspawns[efg][tempindex]
pointspawns[int(efg)].insert(abc,0)
从本质上讲，我必须将颗粒的生成放入一个函数中，然后将 collsions 检测作为另一个函数，然后在我的 for 循环中使用 vaules 或 row 和 n 我计算出我需要使用的确切列表和索引，然后我用 0 替换元素以重新绘制无处。 抱歉，如果代码看起来有点混乱并且我知道我的变量名称很糟糕， 但我真的在 2 小时后完成了这个，所以我现在要休息一下
