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?
