IndexError: list index out of range pygame

Question

它说列表索引超出范围，我不知道为什么。有谁知道如何解决这个问题？

我要导入的东西的代码

from os import walk
import pygame

def import_folder(path):
    surface_list = []

    for _, __, img_files in walk(path):
        for image in img_files:
            full_path = path + '/' + image
            image_surf = pygame.image.load(full_path).convert_alpha()
            surface_list.append(image_surf)

    return surface_list

我正在使用它的代码：

import pygame
from support import import_folder

class Player(pygame.sprite.Sprite):
    def __init__(self, pos):
        super().__init__()
        self.import_character()
        self.frame_index = 0
        self.animation_speed = 0.15
        self.image = self.animations['run'][self.frame_index]
        
        # Player Movement

        self.direction = pygame.math.Vector2(0, 0)
        self.speed = 8
        self.gravity = 0.8
        self.jump_speed = -16

    def import_character(self):
        character_path = '../graphics/character/'
        self.animations = {'idle':['idle'], 'run':[], 'jump':[], 'fall':[]}

        for animation in self.animations.keys():
            full_path = character_path + animation
            self.animations[animation] = import_folder(full_path)

完整错误代码（从 Traceback 开始）：

IndexError: list index out of range

Answer 1

与“运行”动画的图像数量相比，frame_index 变得太大了。

试试这样的东西：

self.image = self.animations['run'][self.frame_index % len(self.animations['run'])]

Answer 2

if len(self.animations['run'])>0:
   self.animations['run'][self.frame_index]
else:
   condition

Answer 3

您的图片文件加载不正确。如果文件路径不对错，walk(path) returns 什么都没有。
将文件放在项目的同一目录或子目录中是不够的。您还需要设置工作目录。图像文件路径必须相对于当前工作目录。工作目录可能与 python 脚本的目录不同。
可以使用 __file__ and the current working directory can be changed with os.chdir(path).

检索文件的名称和路径

在主代码的开头添加以下内容，将工作目录设置为与主脚本的目录相同：

import os
os.chdir(os.path.dirname(os.path.abspath(__file__)))
