I'm writing a roguelike with libtcodpy. It works, but when I run this listing: http://kooneiform.wordpress.com/2009/03/29/241/ at the bottom of the page is a full listing and a few others I've tried, I get errors such as this:
FYI I'm on Windows and do have the libtcodpy.py, SDL.dll, libtcod-mingw.dll files and they do work when following the tutorial that is most popular for libtcodpy.
For the listing above I receive this specific error:
$ python roguelike_practice2.py
Traceback (most recent call last):
File "roguelike_practice2.py", line 165, in <module>

File "roguelike_practice2.py", line 98, in draw
libtcod.console_set_foreground_color(0, libtcod.white)
AttributeError: 'module' object has no attribute 'console_set_foreground_color'
I also on that same program encounter the exact same issue with console_set_background_color, console_print_left. None work. All with the same error.

AttributeError: function 'TCOD_console_set_fore' not found
I run into this TCOD_console_set_fore error a bunch. But say I comment that out, I get the same error but with another function such as TCOD_console_set_back, and others.
Not sure why I'm getting these errors. Using Python 2.7.9 32 bit, and libtcod 1.5.1 I believe. Running Windows 7 64 bit. Keep in mind I can get other programs to run that don't require any of those set_foreground and variation functions, or the print_left function or whatever other functions aren't working. But I'm sure it one or two issues affecting all the functions that wont work. \
If anyone has any ideas, I've spent a ton of time looking online to no avail for info. And the forum for libtcod takes days for administrator approval to join - lame.
Anyway thanks in advance! Ask me any questions or if you need clarification.
TCOD 1.5.1 renamed some functions, so that is why your two listings are crashing.
Version 1.5.1 renamed console_set_foreground_color to console_set_default_foreground,console_set_background_color to console_set_default_background, console_set_fore and console_set_back to console_set_char_foreground and console_set_char_background respectively, and console_wait_for_keypress has been replaced with sys_wait_for_event.
Also, console_print_left has been replaced by console_print_ex, which has an extra 'alignment' parameter between background and the string to print.
