在this question中，我想通過按空格鍵來弄清楚如何分割細胞。我現在想知道如何讓它們自己合併在一起，假設在30秒之後。新合併的細胞將其他兩個細胞的質量合併在一起。Pygame：細胞合併回來

if not splitting:
pygame.draw.circle(thesurface, playercolor, player.center, size)

pygame.draw.circle(thesurface, playercolor,(player.centerx,player.centery),int(size/2))
pygame.draw.circle(thesurface, playercolor,(player.centerx+size,player.centery+size),int(size/2))
# check if the player has intersected with any food squares.
for food in foods[:]:
if player.colliderect(food):
foods.remove(food)
size+=1
# draw the food
for i in range(len(foods)):
pygame.draw.rect(thesurface, GREEN, foods[i])
printscore = basicFont.render("Score: %d" % size, True, (0,0,0))
thesurface.blit(printscore, (10, 550))
pygame.display.update()
# draw the window onto the thesurface
pygame.display.update()
mainClock.tick(80)
我覺得這涉及刪除兩個圓圈和添加一個，但我不知道如何與它前進，因爲該方案現在似乎脆弱。
非常感謝幫助！
