Re: [pygame] Object not moving!

[Tanner Johnson <tbjohnson42@xxxxxxxxx>]

I'm the 'point me in the right direction' type, so here's a vague description of where to go to fix this bug. If you want a more explicit answer, let me know!

Take a look at the line where you're blitting the image and look at your inputs to that function. There's a problem there. Take a look at the blit documentation and see what you can do to fix it.

Once you resolve that, you'll see a second bug, but the answer to that one should be pretty easy to figure out.

Happy pygaming!

Hello everyone! I was having a little bug in my program. I HAVE NO IDEA WHY! I put print statements everywhere to check to make sure everything was being executed. Here is my code:

import pygame, sys

from pygame.locals import *

pygame.init()

screen = pygame.display.set_mode((640,480))

class goodGuy(pygame.sprite.Sprite):

    def __init__(self):

        pygame.sprite.Sprite.__init__(self)

        self.image = pygame.image.load('goodGuy.png')

        self.rect = self.image.get_rect()

    def up(self):

        print 'up'

        self.rect[1] -= 10

    def down(self):

        print 'down'

        self.rect[1] += 10

    def right(self):

        print 'right'

        self.rect[0] += 10

    def left(self):

        print 'left'

        self.rect[0] -= 10

Guy = goodGuy()

while True:

    for event in pygame.event.get():

        if event.type == pygame.KEYDOWN:

            if event.key == K_UP:

                Guy.up()

                print 'Up'

            if event.key == K_DOWN:

                Guy.down()

                print 'Down'

            if event.key == K_RIGHT:

                Guy.right()

                print 'Right'

            if event.key == K_LEFT:

                Guy.left()

                print 'Left'

            if event.key == K_ESCAPE:

                pygame.quit()

                sys.exit()

        screen.blit(Guy.image, Guy.rect, Guy.rect)

        pygame.display.update()

All that I want to happen is that for each respective arrow key, I want to move the image 10 pixels in that direction. Any help?
