Talk:Complete Roguelike Tutorial, using python+libtcod, part 1

Instead of the awkward

    if not first_time:

may I suggest to just put things in the order in which they are meant to be executed?

    libtcod.console_set_foreground_color(0, libtcod.white)
    libtcod.console_print_left(0, playerx, playery, libtcod.BKGND_NONE, '@')
    libtcod.console_flush()
    libtcod.console_print_left(0, playerx, playery, libtcod.BKGND_NONE, ' ')

    exit = handle_keys()
    if exit:
        break

Sure. The logic you're pointing out was only added as an afterthought to correct a small bug: the first frame for a turn-based game wouldn't be shown while waiting for input. When someone pointed out the bug this was added as a quick-fix. I'll change it to the better solution soon (remember I also have to make the same change to all the "whole code" pages...).

Done. Had to manually update about 10 "whole code" pages but it's for the better, I never liked that logic anyway. Jotaf 22:35, 7 November 2010 (UTC)

I'm very much enjoying this tutorial! It is immensely helpful and informative. However, I have two questions, that I, as a python-noob, don't understand:

1. libtcod.console_flush() comes before the code that overwrites the '@' with ' '. Doesn't that mean, that the old character gets overwritten AFTER the output? I don't understand how that works.
2. When I press left arrow, and then up right after, my @ moves left two times and up once. Is that because of console_is_key_pressed? Is that the way it's supposed to work?

OS X

N00b here. I'm having a difficult time translating this tutorial for OS X 10.6.8. I've downloaded an OS X version of the libtcod library, but I'm not sure which files to put in the working directory. I'm not sure if I have to install libtcod onto my system in some more general way, and if so, how I would do that.

Could anyone give a quick rundown of that process?

UPDATE: I managed to install libtcod through homebrew (which seemed the easiest possible way to do it). I used it to compile and run the libtcod samples c and c++ code in the 1.5.1 OSX download. However, the python sample gives me errors:

Traceback (most recent call last):

 File "samples_py.py", line 9, in <module>
   import libtcodpy as libtcod
 File "/Users/user/build/libtcod/libtcodpy.py", line 46, in <module>
   _lib = ctypes.cdll['./libtcod.dylib']
 File "/usr/local/Cellar/python/2.7.8_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ctypes/__init__.py", line 440, in __getitem__
   return getattr(self, name)
 File "/usr/local/Cellar/python/2.7.8_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ctypes/__init__.py", line 435, in __getattr__
   dll = self._dlltype(name)
 File "/usr/local/Cellar/python/2.7.8_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ctypes/__init__.py", line 365, in __init__
   self._handle = _dlopen(self._name, mode)

OSError: dlopen(./libtcod.dylib, 6): image not found

UPDATE UPDATE: Ok, the problem was that libtcodpy.py could not find libtcod.dylib. I changed the path in the script to fix that, and it seems to work. Hopefully that won't mess anything else up. If it does, I'll try copying the file from /usr/local/Cellar/libtcod/1.5.1/lib to my working directory. If no more issues come up, I'll erase this whole thing and put up a step-by-step on how I set this up.

Thanks for documenting your process. It will be helpful to other OS X users.-Muscles (talk) 21:13, 3 November 2014 (CET)
