Re: [pygame] Sprite troubles
self.image, self.rect = loadImage('ground.bmp', -1)
I seem to recognize that function from somewhere. The pygame.org cookbook?
If so, -1 triggers the function to set the colorkey by picking the color
from the pixel at point 0,0 in your image. If your image is a solid color,
this would result in an image of essentially transparent pixels.

[pygame] Sprite troubles
Hi everyone,
it sounds like a stupid question but i have written a really simple program
where i just want to add a sprite to a sprite group and then draw the
containing of this group.
Here is the main code :
import pygame
from sprites import Node
pygame.init()
screen = pygame.display.set_mode((640, 480))
node_group = pygame.sprite.RenderPlain()
node = Node((156, 234), 0)
node_group.add(node)
while 1:
node_group.update()
node_group.draw(screen)
pygame.display.flip()
And here is my sprite class :
import pygame
from pygame.locals import *
from loads import loadImage
class Node(pygame.sprite.Sprite):
'''
Node class represent the sprite of each node of the
map. So, one instance of Node is created for each
node.
'''
def __init__(self, pos, node_type):
pygame.sprite.Sprite.__init__(self)
self.pos = pos
self.node_type = node_type
if self.node_type == 0:
self.image, self.rect = loadImage('ground.bmp', -1)
elif self.node_type == 1:
self.image, self.rect = loadImage('wall.bmp', -1)
elif self.node_type == 2:
self.image, self.rect = loadImage('hole.bmp', -1)
self.rect.topleft = pos
def update(self):
pass
I maybe a bit tired but i can't see what i m doing wrong...
Thanks for your help.
Re: [pygame] Sprite troubles
Yeah that's true... Sorry about that. My problem is that the sprite in the
RenderGroup is simply not drawn.

Re: [pygame] Sprite troubles
RenderPlain? What's that? It's not mentioned here:
http://www.pygame.org/docs/ref/sprite.html
http://www.pygame.org/docs/ref/sprite.htmlI found it mentioned in some
2002 documentation. I think it might be obsolete. Not sure.
I've been using pygame.sprite.OrderedUpdates.

Re: [pygame] Sprite troubles
From what I gather, pygame.sprite.RenderPlain, in its current form, just
points
to pygame.sprite.Group.

Re: [pygame] Sprite troubles
And what is loads?
I think you might be working from some out-of-date docs, Nathan. I suggest
that you use this (current) version of the pygame docs:
http://www.pygame.org/docs/ref/sprite.html
Here's a working (and almost minimal) pygame sprite-based program (tested
with Python 3.1 and 2.6):
import sys, pygame
pygame.init()
screen = pygame.display.set_mode((200,50), 0)
arial = pygame.font.SysFont( 'arial,microsoftsansserif,courier', 16 )
sprite1 = pygame.sprite.Sprite()
sprite1.image = arial.render('Hello, world!', True, (50,50,50))
sprite1.rect = sprite1.image.get_rect()
sprite1.rect.topleft = (20,10)
sprite_group = pygame.sprite.OrderedUpdates()
sprite_group.add(sprite1)
while True:
event = pygame.event.wait()
if (event.type == pygame.constants.QUIT):
pygame.quit()
sys.exit()
screen.fill((240,240,240))
sprite_group.draw(screen)
pygame.display.update()
Here's almost the same program, but with an event loop that doesn't wait
forever for an event; the changes are in red:
*import sys, pygame*
*pygame.init()*
*clock = pygame.time.Clock()*
*screen = pygame.display.set_mode((200,50), 0)*
*arial = pygame.font.SysFont( 'arial,microsoftsansserif,courier', 16 )*
*sprite1 = pygame.sprite.Sprite()*
*sprite1.image = arial.render('Hello, world!', True, (50,50,50))*
*sprite1.rect = sprite1.image.get_rect()*
*sprite1.rect.topleft = (20,10)*
*sprite_group = pygame.sprite.OrderedUpdates()*
*sprite_group.add(sprite1)*
*while True:*
*for event in pygame.event.get():*
*if (event.type == pygame.constants.QUIT):*
*pygame.quit()*
*sys.exit()*
*screen.fill((240,240,240))*
*sprite_group.draw(screen)*
*pygame.display.update()*
*clock.tick(60)*
This is the same as the first version, except with a resizable window:
*
import sys, pygame
pygame.init()
scrsize = (200,50)
screen = pygame.display.set_mode(scrsize, pygame.constants.RESIZABLE)
arial = pygame.font.SysFont( 'arial,microsoftsansserif,courier', 16 )
sprite1 = pygame.sprite.Sprite()
sprite1.image = arial.render('This window is resizable', True, (50,50,50))
sprite1.rect = sprite1.image.get_rect()
sprite1.rect.topleft = (20,10)
sprite_group = pygame.sprite.OrderedUpdates()
sprite_group.add(sprite1)
while True:
event = pygame.event.wait()
if (event.type == pygame.constants.QUIT):
pygame.quit()
sys.exit()
elif event.type == pygame.constants.VIDEORESIZE:
# this program is in a resizable main window; this event happens
when it's resized
scrsize = event.size # or (event.w, event.h)
screen = pygame.display.set_mode(scrsize,
pygame.constants.RESIZABLE)
screen.fill((240,240,240))
sprite_group.draw(screen)
pygame.display.update()
