pygame图像未加载？

Question

为什么我的悟空精灵没有加载我的左右图像看起来正确但我的其他人没有在运动中播放？我试图完成的事情是让我的角色图像在运动中正常工作 下面是带有完整代码描述链接的代码：

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

这是我尝试更改代码但没有结果的地方。

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在运动中正常工作

问题是self.walkCount 是（整数）除以100：

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

注意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。我建议执行以下操作：

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

如果图片变化太快，则增加walkfps。
