Console black until it is moved about python-tcod HOT 7 CLOSED

I can't reproduce this on Windows. I speculate that the issue might be caused by sleeping rather than waiting for an event.

You could try replacing the sleep with tcod.console_wait_for_keypress(False).

If that doesn't work then you could use a different renderer for tcod.console_init_root such as tcod.RENDERER_OPENGL2, renderers are listed here.

The tcod.FONT_LAYOUT_ASCII_INROW flag is wrong and will be removed.

I need to make a correction (I’ve been trying a handful of things to see what works).
When I run what is on that page, and I run “python3 engine.py”, it never shows a screen at all.

I used a modified version of the code at http://www.rogueliketutorials.com/libtcod/1

`import tcod

def main():
screen_width = 80
screen_height = 50

tcod.console_set_custom_font(
    'dejavu16x16_gs_tc.png',
    tcod.FONT_TYPE_GRAYSCALE | tcod.FONT_LAYOUT_TCOD,
)

root_console = tcod.console_init_root(screen_width, screen_height, 'tcod tutorial revised', False)

while True:
    root_console.clear()

    root_console.print_(10,10, "hello, world")

    tcod.console_flush()

    key = tcod.console_check_for_keypress()

    if key.vk == tcod.KEY_ESCAPE:
        return True

`
When I run this, the screen shows up, but is black.

Oh, and I tried the different render modes and they either caused a crash (probably because those aren't available) or had the same effect

Your code looks correct.

Be sure to change the default background color, example: root_console.default_bg = (0,0,255) in case that gives you something other than a black background.

All renderer modes should work on a modern computer. If there's something in libtcod causing the issue then it'd be useful if I knew which renderers were crashing.

I've tracked the issue down to SDL2, version 2.0.9 fixes this issue, so I'll get it updated.

tcod 8.1.0 should fix the issue. SDL2's changelog was very specific:

Mac OS X:
* Fixed black screen at start on Mac OS X Mojave

I can verify that it is fixed in 8.1.1. Thanks!
