Question

我试图使角色移动，但是当我走一定距离时，它会出错

我找不到可行的解决方案，所以我自己尝试了几件事

global walkCount
win.blit(bg, (0, 0))
if walkCount + 1 >= 27:
    walkCount = 0
if left:
    win.blit(walkLeft[walkCount//3], (x, y))
    walkCount += 1
    pygame.display.update()
elif right:
      win.blit(walkRight[walkCount//3], (x,y))
      walkCount += 1
      pygame.display.update()

File "C:\Users\drfur\Desktop\Game\game.py", line 166, in <module>
   rwg()

File "C:\Users\drfur\Desktop\Game\game.py", line 55, in rwg
   win.blit(walkRight[walkcount//3], (x,y))

IndexError: list index out of range

它发生在左右两侧

Answer 1

walkCount的最大值为26。26//3的结果为8。您必须确保列表walkLeft和walkRight具有9个元素。

通过计算除以列表长度的除数可以避免列表索引超出范围错误。余数可由模运算符（%）计算。参见Operators。例如：

if left:

    i = (walkCount//3) % len(walkLeft)
    win.blit(walkLeft[i], (x, y))

elif right:

    i = (walkCount//3) % len(walkRight)
    win.blit(walkRight[i], (x,y))

walkCount += 1
pygame.display.update()

IndexError：列表索引超出行走字符的范围
