我正在創建一個加載圖像并將其轉換為 1 和零的項目，然后它將使用烏龜繪制它。但是，每次我運行它時，它都會告訴我在第一列完成后它已停止工作。如果問題出在我電腦的處理能力上，我想知道是否有辦法切換到 GPU 來完成任務。任何幫助將不勝感激。謝謝def ShowMaze(possibleRoutes): turtle.delay(0) for x in range(0,len(Maze)): for y in range(0,len(Maze[0])): if Maze[x][y]==3: Maze[x][y]=0 for x in range(0,len(Maze)): turtle.forward(-5) turtle.right(90) turtle.forward(5/len(Maze[0])) turtle.left(90) for y in range(0,len(Maze[0])): if Maze[x][y]==1: turtle.fillcolor("black") turtle.begin_fill() elif Maze[x][y]==0: turtle.fillcolor("white") turtle.begin_fill() elif Maze[x][y]==4: turtle.fillcolor("green") turtle.begin_fill() elif Maze[x][y]==5: turtle.fillcolor("red") turtle.begin_fill() for i in range(0,4): turtle.forward(5/len(Maze[0])) turtle.left(90) turtle.end_fill() turtle.forward(5/len(Maze[0])) input() for ii in range(1,len(possibleRoutes)-1): turtle.pu() turtle.home() turtle.forward(-250) turtle.forward((250/len(Maze))*possibleRoutes[ii][1]) turtle.right(90) turtle.forward((250/len(Maze))*possibleRoutes[ii][0]+(250/len(Maze))) turtle.left(90) turtle.fillcolor("blue") turtle.pd() turtle.begin_fill() for x in range(0,4): turtle.forward(250/len(Maze[0])) turtle.left(90) turtle.end_fill()

這段代碼一團糟。您將一個名為 的 JPEG 迷宮圖像輸入Maze到一個二維數組中并將其傳遞給ShowMaze(Maze)以表明您已正確讀取它。但是全局ShowMaze()訪問Maze并認為它的論點是從未計算過迷宮中的ShowMaze(possibleRoutes)哪個地方possibleRoutes？另外：X 和 Y 的意義Maze似乎顛倒了；迷宮的行list無緣無故地有一層額外的包裹；包含死代碼；你不是把它讀成 1 和 0，而是四種不同的顏色代碼；繪圖代碼似乎沒有希望。
我已經重新編寫了您的代碼，只需將迷宮讀入列表列表，然后使用標記而不是繪圖將其與烏龜一起顯示，以簡化和加速代碼：
from turtle import Screen, Turtle
from PIL import Image
CURSOR_SIZE = 20
PIXEL_SIZE = 5
COLORS = {0: 'white', 1: 'black', 4: 'green', 5: 'red'}
def ShowMaze(maze):
height, width = len(maze), len(maze[0])
screen = Screen()
screen.setup(width * PIXEL_SIZE, height * PIXEL_SIZE)
screen.setworldcoordinates(0, height, width, 0)
turtle = Turtle('square', visible=False)
turtle.shapesize(PIXEL_SIZE / CURSOR_SIZE)
turtle.penup()
screen.tracer(False)
for y in range(height):
for x in range(width):
color = maze[y][x]
if color in COLORS:
turtle.fillcolor(COLORS[color])
else:
turtle.fillcolor("orange") # error color
turtle.stamp()
turtle.forward(1)
turtle.goto(0, turtle.ycor() + 1)
screen.tracer(True)
screen.mainloop()
image = Image.open('ExampleMazePicture.JPG') # Can be many different formats.
width, height = image.size # Get the width and height of the Maze for iterating over
pixels = image.load()
maze = []
for y in range(0, width, 4):
print("Row:", y)
row = []
for x in range(0, width, 4):
node = -1
pixel = pixels[x, y]
if pixel >= (200, 200, 200):
node = 0
elif pixel[0] > 200 and pixel[1] < 200 and pixel[2] < 200:
node = 4
print("End")
elif pixel[0] < 50 and pixel[1] > 200 and pixel[2] < 50:
node = 5
print("Start")
elif pixel <= (50, 50, 50):
node = 1
else:
print(pixel)
row.append(node)
maze.append(row)
ShowMaze(maze)
基于使用“圖 1.6：Picobot 的迷宮”的輸出。從此頁面作為輸入：
希望這能為您最終嘗試開發的程序提供一個起點。
