i have been hitting my head on the wall for several days now, but I still cannot figure out why this crashes:
import pygame, random
#button state variable, order: axes, A(z) B(x) START(enter) SELECT(shift)
#SELECT and START cannot be held
global buttons
buttons = [[0, 0], 0, 0, 0, 0]
pygame.init()
pygame.font.init()
text = pygame.font.Font('PressStart2p.ttf', 8)
debugmode = 1
#read config file
config = open("config.ini")
cfg_resx = int(config.readline())
cfg_resy = int(config.readline())
cfg_res = [cfg_resx, cfg_resy]
cfg_fscreen = config.readline()
if cfg_fscreen == 1:
cfg_fscreen = pygame.FULLSCREEN
global screen
screen = pygame.display.set_mode(cfg_res)
config.close()
logo = pygame.image.load('titletext.bmp')
pygame.event.get()
global output
output = pygame.Surface([255, 240])
def update():
pygame.transform.scale(output, cfg_res, screen)
pygame.display.flip()
screen.fill([0, 0, 0])
for event in pygame.event.get():

update()
pygame.quit()
when I try to run the code, it will work perfectly, until i mouse over the window, then gives me the error:
Traceback (most recent call last):
File "H:\GUNFORCE\main.py", line 113, in <module>

if event.key == pygame.K_UP:
AttributeError: event member not defined
thanks in advance to anyone who might understand why this is crashing
The problem is in this line:
elif event.type -- pygame.KEYUP:
That probably should be:
elif event.type == pygame.KEYUP:
What your original line does is:
elif event.type - (-pygame.KEYUP):
The result of this substraction is most likely a non-zero number, so this condition is always true, and the next line gets executed even for non-key events, such as mouse events. For those events event.key is not defined, hence your error.
