从国际象棋导入国际象棋引擎:国际象棋引擎错误

from Chess import ChessEngine: error on Chess Engine

我已经多次复习教程,但仍然有这个错误。看完系列中的第一个视频后,他就可以展示棋盘了。该错误在我的导入语句中突出显示了 ChessEngine。

这是我的主要资源:https://www.youtube.com/watch?v=EnYui0e73Rs&t=2095s

这是错误: 导入错误:无法从 'Chess'(未知位置)

导入名称 'ChessEngine'

请停止

我的代码如下

***import pygame as p
from Chess import ChessEngine
WIDTH = HEIGHT = 512  # optional 400
DIMENSIONS = 8  # dimensions are 8x8
SQ_SIZE = HEIGHT // DIMENSIONS
MAX_FPS = 15  # For animation
IMAGES = {}
'''
Initialize global dictionary of images. this will be called once in the main
'''
def load_images():
    pieces = ["wp", "wR", "wN", "wB", "wQ", "wK", "wB", "wN", "wR", "bp", "bR", "bN", "bB", "bQ", "bK", "bB", "bN",
              "bR"]
    for piece in pieces:
        IMAGES[piece] = p.transform.scale(p.image.load("images/" + piece + "wp.png"), (SQ_SIZE, SQ_SIZE))
#         note: we can access an image by saying 'IMAGES['wp']
'''
main driver for our code  handles user input and updating graphics 
'''
def main():
    p.init()
    screen = p.display.set_mode((WIDTH, HEIGHT))
    clock = p.time.Clock()
    screen.fill(p.Color("white"))
    gs = ChessEngine.GameState()
    print(gs.board)
    load_images()  # only operated once
    running = True
    while running:
        for e in p.event.get():
            if e.type == p.QUIT:
                running = False
            drawGameState((screen, gs))
            clock.tick(MAX_FPS)
            p.display.flip()
def drawGameState(screen, gs):
    drawBoard(screen) #draw squares on board
    drawPieces(screen, gs.board)
def drawBoard(screen):
    colors = [p.Color("white", p.Color("grey"))]
    for r in range(DIMENSIONS):
        for c in range(DIMENSIONS):
            color = colors[((r+c) % 2)]
            p.draw.rect(screen, color, p.Rect(c*SQ_SIZE, r*SQ_SIZE, SQ_SIZE, SQ_SIZE))
def drawPieces(screen, board):
    '''

如果你看youtube视频的文件夹结构,他有一个名为Chess的根文件夹:

| Chess
| | --> images
| | --> ChessEngine.py
| | --> __init__.py 
| ...

当您声明 import 时,如果存在具有导入名称的模块(文件夹或文件),python 将搜索调用文件夹(根文件夹)。如果文件夹包含 __init__.py 文件,它将被视为一个模块。

您有两种选择:

  1. 有一个名为 Chess.py 的文件,其中包含导出的成员 ChessEngine
  2. 有一个名为 Chess 的文件夹,其中的 __init__.py 文件公开了 ChessEngine 成员

我想如果您遵循所链接的整个教程,他们会告诉您如何从 __init__.py 文件公开成员。

如果您想更好地了解 the import system (Docs Python) 的工作原理,可以查看文档。
