Coding query

This program runs OK on a Pi b+ under Wheezie but on transfering it to a Pi2 running Jessie it gives the error 'No video mode has been set'. It calls a gif file in the same directory called spritesheet.gif. I have not so far found any help in my reading; can anyone advise. The ##### is to indicate the faulty line.

#!/usr/bin/env python #animation.py

import pygame,sys from pygame.locals import*

pygame.init()

pygame.display.set_caption( 'Malcs Game2')

RED=(255,0,0) clock=pygame.time.Clock()

counter=0 sprites=[]

sheet=pygame.image.load('spritesheet.gif').convert_alpha()######## width=sheet.get_width() for event in pygame.event.get(): if event.type==QUIT: pygame.quit() sys.exit()

for i in range(int(width/128)): sprites.append(sheet.subsurface(i*128,0,128,128))

ZONE.fill(RED) ZONE.blit(sprites[counter],(10,10))

counter=(counter+1)%8

clock.tick(16)

Did you type this is in yourself or did you copy it from your old Wheezie installation?

Copied from the old Wheezie

when a python program errors out it is always a good idea to copy and paste the full trace back this is usually very good at pinning down exactly where the error occurred

Well I have got to admit being wrong in what I said above. I set up the PiB+ only to find the program does NOT run. The error given is 'pygame not found'. Does the above,re errors, mean keep a record of the displayed error?

I've a feeling it says a lot more than "pygame not found".

Maybe more like this:

Traceback (most recent call last): File "gametest.py", line 4, in import pygame,sys ImportError: No module named 'pygame'

So to help ensure python debugging help is accurate you should copy everything from the "Traceback..."

Your code is missing a mode setting statement. If you execute the following query:

you will see help on how to solve this.

Thanks for that info, a lot to get my teeth into! Looks like tomorrow night is testing time. Amazing how much info is around if you know how to find it.

pygame not found can be overcome with:

sudo apt-get install python-pygame

As for the video mode not set error:

I believe that you need to call:

screen = pygame.display.set_mode((800, 600)) # change to the real resolution this call will actually return the surface that you want to blit on.

Sounds about right, but I have little experience with python and less with pygame.
