So I'm making a game to test my programming skills and I'm trying to use pygame but when i try and load a level map it says the surface has quit. I have no idea why.
This is the load code:
def load(self):
print(os.listdir())
file = input('>>> file name = ')
try:
self.Dir = os.getcwd()
path = os.path.join(self.Dir, "maps", file)
data = pickle.load(open(path, 'rb'))
except OSError as error:
print('Not file ', path)
print(error)
else:
self.grid = data[0]
self.blocks = data[1]
Thanks in advance
EDIT:
this is the trace back
Traceback (most recent call last):
File "F:\PROGRAMS\snow\mapmaker_v2.py", line 169, in <module>
a.loop()
File "F:\PROGRAMS\snow\senpy.py", line 95, in loop

self.spritedict[spr] = surface_blit(spr.image, spr.rect)
pygame.error: display Surface quit
EDIT 2:
This is the loop code where it happens:
(The load command is in the self.keyboard() function.)
def loop(self):
print('looping')
for event in pygame.event.get():
if event.type == pygame.QUIT:
print('quiting :(')
pygame.display.quit()
quit('User quit')
self.screen.fill((237, 237, 237))
self.keys = pygame.key.get_pressed()
self.mos = pygame.mouse.get_pressed()
self.mouse()
self.keyboard()
#screen.blit(player,player.pos)
self.blocks.draw(self.screen)
self.extraLoop()
pygame.display.flip()
print('done looping')
You can't pickle a Surface object.
If you want to pickle an object that contains a Surface, remove it before saving it to disk; and store the name of the image file or a string representation of the Surface instead in the object.

I hope it run and do not stop.

I'm totally stuck on this,please help me.
I've reworked your code fragment into what I believe you are trying to do. Avoid eval as it can cause endless problems. Your use of global in this context isn't valid. See if this works for you:
from turtle import Screen, Turtle
class Body:
def __init__(self, positions):
self.cells = []
self.make_body(positions)
# self.a()
# self.Alive(screen)
def make_body(self, positions):
for position in positions:
cell = Turtle(shape='square')
cell.fillcolor('white')
cell.penup()
cell.goto(position)
self.cells.append(cell)
def restart():
start_positions.clear()
y = 250
for _ in range(25):
x = -250
for _ in range(25):
start_positions.append((x, y))
x += 20
y -= 20
start_positions = []
screen = Screen()
screen.setup(550, 550)
screen.bgcolor('black')
screen.tracer(False)
restart()
my_body = Body(start_positions)
screen.tracer(True)
screen.exitonclick()
Since I've turned off tracer() for speed, call screen.update() whenever you're ready for the user to see the most recent changes.
*Nanpy allows for a Raspi to have an Arduino slave through python
Right now I'm having extreme difficulty in using the nanpy Servo package, and I cant get it to run correctly. I'm using it to make a robot that is wirelessly controlled from a computer, this is what I have for code:
from nanpy import (ArduinoApi, SerialManager)
import pygame
from nanpy import Servo
import time
pygame.init()
a=0
d=0
window = pygame.display.set_mode((800,600))
pygame.display.set_caption("Console")
try :
connection = SerialManager()
ard = ArduinoApi(connection = connection)
run = True
except:
print("Connection Failed!")
servoA = Servo(2)
servoD = Servo(4)
while run :
for event in pygame.event.get():
keys = pygame.key.get_pressed()
# if (event.type==pygame.KEYDOWN):
if keys[pygame.K_s] and keys[pygame.K_a]:
a=a-1
servoA.write(a)
elif keys[pygame.K_s] and keys[pygame.K_d]:
d=d-1
servoD.write(d)
elif keys[pygame.K_w]:
a=a+1
d=d+1
servoD.write(d)
servoA.write(a)
elif keys[pygame.K_s]:
a=a-1
d=d-1
servoD.write(d)
servoA.write(a)
elif keys[pygame.K_d]:
d=d+1
servoD.write(d)
elif keys[pygame.K_a]:
a=a+1
servoA.write(a)
elif keys[pygame.K_t]:
run=False
pygame.quit()
This is the error the python shell throws:
Traceback (most recent call last):
File "/home/pi/Desktop/nanpy/RobotCode.py", line 28, in <module>

raise SerialManagerError('Serial timeout!')

How can I fix this, and/or what am I doing wrong?
You need to specify the port of the Arduino. So could you try:
connection = SerialManager(device='/dev/ttyACM0')
or whatever port you are using.
update the configuration file to use the servo and upload it to arduino using the IDE then run this program.
you can find the cfg.h file in nanpy-firmware/nanpy folder.
I am working on a python program that displays a series of images using Tkinter and ImageTk. I have not been able to display more than a single image. Below is a small complete program that reproduces the error. The program searches the current directly recursively for jpg files, and displays them as the uses presses Enter.
import Tkinter, ImageTk,os, re
def ls_rec(direc):
try:
ls = os.listdir(direc)
except Exception as e:
return
for f in os.listdir(direc):
fpath = os.path.join(direc, f)
if os.path.isfile(fpath):
yield fpath
elif os.path.isdir(fpath):
for f2 in iterate_dir(os.path.join(direc,f)):
yield f2
images = filter(lambda a:re.match('.*\\.jpg$',a),ls_rec(os.getcwd()))
assert(len(images)>10)
top = Tkinter.Tk()
image_label = Tkinter.Label(top)
Label_text = Tkinter.Label(top,text="Below is an image")
img = None
i = 0
def get_next_image(event = None):
global i, img
i+=1
img = ImageTk.PhotoImage(images[i])
label.config(image=img)
label.image = img
top.bind('<Enter>',get_next_image)
label.pack(side='bottom')
Label_text.pack(side='top')
get_next_image()
top.mainloop()
The program fails with the following traceback:
Traceback (most recent call last):
File "/usr/lib/python2.7/pdb.py", line 1314, in main

Does anyone get the same behavior when running this code? What am I doing wrong?
EDIT: Using korylprince's solution, and a bit of cleaning, the following is a working version of the original code:
import os, re, Tkinter, ImageTk
def ls_rec(direc, filter_fun=lambda a:True):
for (dirname, dirnames, fnames) in os.walk(direc):
for fname in fnames:
if filter_fun(fname):
yield os.path.join(dirname,fname)
top = Tkinter.Tk()
image_label = Tkinter.Label(top)
text_label = Tkinter.Label(top,text="Below is an image")
images = ls_rec(os.getcwd(), lambda a:re.match('.*\\.jpg$',a))
imgL = []
def get_next_image(event = None):
fname = images.next()
print fname
fhandle = open(fname)
img = ImageTk.PhotoImage(file=fhandle)
fhandle.close()
imgL.append(img)
image_label.config(image=img)
top.bind('<Return>',get_next_image)
image_label.pack(side='bottom')
text_label.pack(side='top')
get_next_image()
top.mainloop()
Edit: top.bind('<Enter>'...) actually bound the event of the mouse entering the frame, rather than user pressing Enter key. The correct line is top.bind('<Return>',...).
ImageTk.PhotoImage is not really documented properly.
You should try something like this:
#outside of functions
images = list()
#inside function
global images
with open(images[i]) as f:
img = ImageTk.PhotoImage(file=f)
images.append(img)
The reason for putting the image in the list is so that python will have a reference to it. Otherwise the garbage collector will delete the image object eventually.
My program gives me this error:

You might be mistakenly using too large values.
Edit: Since I can't comment, what are the sizes of self._x, self._y, and self._r?
