pygame图像未加载？

Question

为什么我的小悟空精灵没有加载我的左右图像，而我的其他小悟空精灵没有在运动中播放？我试图完成的主要任务是让我的角色图像在运动中正常工作 以下是带有完整代码说明链接的代码：

import pygame

pygame.init()#We always need to initialize our pygame IN EVERY PROJECT/FILE

win = pygame.display.set_mode((500, 480))# Here win is representing "window" for our screen which we have set at 500 by 480

pygame.display.set_caption("First Game")#We are giving our Window/Screen a name

walkRight = [pygame.image.load('image/gokuR0.png'), pygame.image.load('image/gokutest2.png'), pygame.image.load('image/gokuR2.png')]
walkLeft = [pygame.image.load('image/gokuL0.png'), pygame.image.load('image/gokutest.png'), pygame.image.load('image/gokuL2.png')]
bg = pygame.image.load('image/bg.jpg')
char = pygame.image.load('image/goku sprite - standing.png')

clock = pygame.time.Clock()

class player():
    def __init__(self, x, y, width, height):
        self.x = x
        self.y = y
        self.width = width
        self.height = height
        self.vel = 5
        self.isJump = False
        self.left = False
        self.right = False
        self.walkCount = 0
        self.jumpCount = 10
        self.standing = False

这里是我试图修改代码的地方，但没有结果

def draw(self, win):
    if self.walkCount + 1 >= 8:
        self.walkCount = 0

    if not self.standing:
        if self.left:
            win.blit(walkLeft[self.walkCount // 100], (self.x, self.y))
            self.walkCount += 1
        elif self.right:
            win.blit(walkRight[self.walkCount // 100], (self.x, self.y))
            self.walkCount += 1
    else:
        if self.right:
            win.blit(walkRight[0], (self.x, self.y))
        else:
            win.blit(walkLeft[0], (self.x, self.y))
    pygame.display.flip()
    print(walkLeft)
    print(walkRight)

class projectile():
    def __init__(self, x, y, radius, color, facing):
        self.x = x
        self.y = y
        self.radius = radius
        self.color = color
        self.facing = facing
        self.vel = 8 * facing

    def draw(self, win):
        pygame.draw.circle(win, self.color, (self.x, self.y), self.radius)

所有这些图像都正常工作，但似乎无法让我的主要角色图像正常工作

问题是self.walkCount是（整数）除以100：

win.blit(walkLeft[self.walkCount // 100], (self.x, self.y))

注self.walkCount永远不会超过7，因为：

if self.walkCount + 1 >= 8:
   self.walkCount = 0

所以self.walkCount // 100的结果总是0

无论如何，这段代码毫无意义，因为walkLeft和walkRight是包含3个图像的列表。我建议采取以下措施：

def draw(self, win):
    walkfps = 10

    if self.standing:
        self.walkCount = 0
        if self.right:
            win.blit(walkRight[0], (self.x, self.y))
        else:
            win.blit(walkLeft[0], (self.x, self.y))

    elif self.left:
        if self.walkCount // walkfps >= len(walkLeft):
            self.walkCount = 0 
        win.blit(walkLeft[self.walkCount // walkfps], (self.x, self.y))
        self.walkCount += 1

    elif self.right:
        if self.walkCount // walkfps >= len(walkRight):
            self.walkCount = 0 
        win.blit(walkRight[self.walkCount // walkfps], (self.x, self.y))
        self.walkCount += 1

如果图像变化迅速，则增加walkfps
