为什么我的角色动画超出范围

我正在尝试让动画发挥作用。但是当我运行游戏时，我按下键进行打孔，当它完成动画时，游戏会出现错误

\Desktop\python projects\Ultamate Brawl\Ultamite BRAWL.py", line 41, in redrawGameWindow
   win.blit(PunchR[punchcount//2], (xcor, ycor))
       IndexError: list index out of range
[Finished in 6.4s]

我看着我的代码，看起来很好

def redrawGameWindow():
    global punchcount 
    global walkcount

    win.blit(bg, (-70,0))
    if walkcount + 1 >= 27:
        walkcount = 0
    if punch == True:
        if punchcount > 49:
            punchcount = 1
        win.blit(PunchR[punchcount//2], (xcor, ycor))
        punchcount += 1
        
        
    elif isjump:
        win.blit(superjump, (xcor,ycor))
    
    elif left:
        if walkcount > 49:
            walkcount = 1
        win.blit(walkLeft[walkcount//4], (xcor, ycor))
        walkcount += 1

    elif right:
        win.blit(walkRight[walkcount//4], (xcor,ycor))
        walkcount += 1
    else:
        win.blit(char, (xcor,ycor))

    pygame.display.update()

我建议，以评估在列表中元素的个数PunchR由len()。设置punchcount=0订阅是否会超出范围。因此，您的算法与列表的长度无关：

if punchcount//2 >= len(PunchR):
    punchcount = 0
win.blit(PunchR[punchcount//2], (xcor, ycor))
punchcount += 1

如果只想运行一次动画，则必须设置punch = False到达列表末尾的时间：

if punch == True:
    if punchcount//2 >= len(PunchR):
        punchcount = 0
        punch = False
    win.blit(PunchR[punchcount//2], (xcor, ycor))
    punchcount += 1
