Do you have a link to landscape.bmp and sky.png?
Traceback (most recent call last):
File "mode7.py", line 9, in ?
ground = pygame.image.load("landscape.bmp") ## 1000x1000 works
pygame.error: Couldn't open landscape.bmp
Traceback (most recent call last):
File "mode7.py", line 10, in ?
sky = pygame.image.load("sky.png") ## At least 800x300
pygame.error: Couldn't open sky.png
I converted the landscape.jpg to landscape.bmp to get the second Traceback.
This looks nice!
Arigato!
