X-Git-Tag: tce~1338 X-Git-Url: https://plomlompom.com/repos/%7B%7Bdb.prefix%7D%7D/%7B%7B%20web_path%20%7D%7D/%7B%7Bprefix%7D%7D/todo?a=commitdiff_plain;h=3d455d7de0778ee27e234412c9b0ad253cf8a4ed;p=plomrogue Completely rebuilt how window borders are realized. Are now drawn in top window, whereas individual "Win" windows are drawn in the spaces between the top windows' border drawings. --- diff --git a/roguelike.c b/roguelike.c index 052f7ff..d2e8303 100644 --- a/roguelike.c +++ b/roguelike.c @@ -31,22 +31,20 @@ void draw_with_linebreaks (struct Win * win, char * text, int start_y) { // Write text into window content space.
