Re: [pygame] how hexcolour arrays works?

Hi

First of all, why do you write that many instruction on one line??

This looks much nicer (ok, it gets a bit longer, but clearer to read):

import pygame,random
pygame.init()
a=[]*8  #- same as 'dim a[8]' from sdlBasic?
a[0]=0x883746
a[1]=0xA88721
a[2]=0xBDE87A
a[3]=0xEE875F   #- list assignment index out of range?
a[4]=0xFE98A1
a[5]=0x334836
a[6]=0x374838
a[7]=0xAAB398
screen=pygame.display.set_mode((320,240))
bkgd=pygame.Surface(screen.get_size())
bkgd=bkgd.convert()
bkgd.fill(a[random.random()*7])
pygame.display.set_caption("move a box")
box=pygame.Surface((25,25))
box=box.convert()
box.fill(a[random.random()*7])
box_x=0
box_y=100
clock=pygame.time.Clock()
kpg=True
while kpg:
 clock.tick(30)
 for event in pygame.event.get():
   if event.type==pygame.QUIT:kpg=False
 box_x+=5
 if box_x>screen.get_width():box_x=0
 screen.blit(bkgd,(0,0))
 screen.blit(box,(box_x,box_y))
 pygame.display.flip()


#----------
This 'a = []*8  ' does not what you expect. See documentation.


import pygame,random
pygame.init()
# nice thing about python, just init the list with the values
a = [0x883746, 0xA88721, 0xBDE87A, 0xEE875F, 0xFE98A1, 0x334836, 0x374838, 0xAAB398]
screen = pygame.display.set_mode((320,240))
bkgd = pygame.Surface(screen.get_size())
bkgd = bkgd.convert()
# might be better to use randint(lower, upper)
bkgd.fill(a[random.randint(0,7)])
pygame.display.set_caption("move a box")
box = pygame.Surface((25,25))
box = box.convert()
# same here, use randint
box.fill(a[random.randint(0,7)])
box_x = 0
box_y = 100
clock = pygame.time.Clock()
kpg = True
while kpg:
 clock.tick(30)
 for event in pygame.event.get():
   if event.type==pygame.QUIT:
     kpg = False
 box_x += 5
 if box_x>screen.get_width():
   box_x = 0
 screen.blit(bkgd,(0,0))
 screen.blit(box,(box_x, box_y))
 pygame.display.flip()
