异常：错误：尝试绘制没有纹理集的精灵

问题描述

因此，基本上，我正在使用python和arcade库开发自上而下的2d游戏，而我对此还是陌生的。下面给出的是我为角色制作的简单闲置动画的代码。

import arcade
import os


SCREEN_TITLE = "shooting_game"

SPRITE_IMAGE_SIZE = 32

SPRITE_SCALING_PLAYER = 1
SPRITE_SCALING_TILES = 2

SPRITE_SIZE = int(SPRITE_IMAGE_SIZE * SPRITE_SCALING_PLAYER)

SCREEN_GRID_WIDTH = 15
SCREEN_GRID_HEIGHT = 7

SCREEN_WIDTH = SPRITE_SIZE * SCREEN_GRID_WIDTH
SCREEN_HEIGHT = SPRITE_SIZE * SCREEN_GRID_HEIGHT


PLAYER_MOVEMENT_SPEED = 3


RIGHT_FACING = 0
LEFT_FACING = 1


def loadtexture(filename):

return [
    arcade.load_texture(filename),arcade.load_texture(filename,flipped_horizontally=True)
]


class PlayerCharacter(arcade.Sprite):
""" Player sprite """
def __init__(self):

    # set up parent class
    super().__init__()

    # Default to face right
    self.character_face_direction = RIGHT_FACING

    # Used for filliping between image sequence
    self.cur_texture = 0
    self.scale = SPRITE_SCALING_PLAYER

    # ____Load texture_______
    main_path = "maps/knight/idle"

我不太确定，但是此时我遇到了错误

    # load texture for ideal standing
    self.idle_texture = []
    for i in range(4):
        texture = load_texture(f"{main_path}/idle_anim_{i}.png")
        self.idle_texture.append(texture)

在此上方代码中

我的角色也没有翻转

def update_animation(self,delta_time: float = 1/60):
    # figure out if we need to face left or right
    if self.change_x < 0 and self.character_face_direction == RIGHT_FACING:
        self.character_face_direction = LEFT_FACING
    elif self.change_x > 0 and self.character_face_direction == LEFT_FACING:
        self.character_face_direction = RIGHT_FACING

    # idle animation
    if self.change_x == 1 and self.change_y == 0:
        self.texture = self.idle_texture[self.character_face_direction]
        return

main()

我的问题是，当我执行此代码时，它将为我的角色空闲动画显示“异常：错误：尝试绘制没有纹理集的精灵”。或将显示文件未找到错误的错误。请有人帮我解决这个问题，持续2天。
