求教，这段代码怎么运行不起来？
from kivy.app import Appfrom kivy.uix.widget import Widget
from kivy.graphics import Color,Rectangle
from kivy.core.window import Window
from kivy.clock import Clock
from kivy.uix.label import Label
import random
FPS = 6
SPEED = 40
WIDTH = Window.size
HEIGHT = Window.size
class MainBoard(Widget):
head = [(WIDTH/2)//SPEED*SPEED,(HEIGHT/2)//SPEED*SPEED]
body = [[(WIDTH/2)//SPEED*SPEED + SPEED,(HEIGHT/2)//SPEED*SPEED]]
apples = []
direction = "left"
touchDown = []
GameOcer = False
def on_touch_down(self,touch):#点击开始
self.touchDown = ,touch.pos]
def on_touch_up(self,touch):
hor = touch.pos - self.touchDown
ver = touch.pos - self.touchDown
if abs(hor)>abs(ver):
if hor>0:
self.direction = "right"
else:
self.direction = "left"
else:
if ver>0:
self.direction = "up"
else:
self.direction = "down"
def createApple(self):
while True:
newApple =
if newApple not in self.apples and newApple != self.head and newApple not in self.body:
self.apples.append(newApple)
break
def update(self,dt):
self.canvas.clear()
self.clear_widgets()
if self.GameOver:
self.add_widget(Label(text = "GameOver! score: % d"%(len(self.body) - 1), pos = (WIDTH/3,HEIGHT/2),font_size = 50))
else:
self.body.insert(0,,self.head])
if self.direction == "left":
self.head -= SPEED
elif self.direction == "right":
self.head += SPEED
elif self.directiom == "up":
self.head += SPEED
elif self.direction == "down":
self.head -= SPEED
if self.head<0 or self.head>WIDTH-SPEED or self.head<0 or self.head>HEIGHT-SPEED or self.head in self.body:
self.GameOver = True
if self.head not in self.apples:
self.body.pop(-1)
else:
self.apples.renmove(self.head)
self.createApple()
with self.canvas:
Color(0.6,0.6,0.6)
Rectangle(pos=self.head,size=(SPEED,SPEED))
with self.canvas:
Color(1,1,1)
for i in self.body:
Rectangle(pos=i,size=(SPEED,SPEED))
with self.canvas:
Color(1,0,0)
for apple in self.apples:
Rectangle(pos=apple,size=(SPEED,SPEED))
class SnakeApp(App):
def build(self):
board = MainBoard()
board.createApple()
Clock.schedule_interval(board.update,1/FPS)
return board
运行以后就只有一个黑色的界面，其他什么都没有，请问是什么原因？
你这个有两点错误，
1、需要运行，你只是定义了两个类，却没有去运行，在文件末尾加上
if __name__ == '__main__':
SnakeApp().run()
2、你有些地方写错了，比较粗心
第69行的renmove改为remove
第60行的directiom改为direction
第23行的GameOcer改为GameOver 2012277033 发表于 2022-3-7 02:55
