在捆绑蛇尾img之后我很难过，有人可以解释一种可能的方法来附加它，所以在每个块添加后它都会停留在最后。
蛇尾是## Snake Images下的可变尾巴

将它插入到snake函数中就像我将它附加到结尾那样接近〜
for XnY in snakeList[0]:
GameDisplay.blit(tail,(snakeList[0][0],snakeList[0][1]))
答案 0 :(得分：0)
我刚刚将我的snakeLength增加到2，并在添加
后解决了我的问题for XnY in snakeList[0]:
GameDisplay.blit(tail,(snakeList[0][0],snakeList[0][1]))
进入蛇的功能。
