From: Christian Heller Date: Thu, 18 Jul 2013 01:44:23 +0000 (+0200) Subject: Support different kinds of monsters and items defined in map object definition struct... X-Git-Tag: tce~1153 X-Git-Url: https://plomlompom.com/repos/%7B%7B%20web_path%20%7D%7D/static/%7B%7Bdb.prefix%7D%7D/%7B%7Bprefix%7D%7D/todos?a=commitdiff_plain;h=d165f8ae619c78fd1ef98a9ba2abdaeeceff853e;p=plomrogue Support different kinds of monsters and items defined in map object definition structs. To support this, large parts of the map object system were rewritten. --- diff --git a/src/draw_wins.c b/src/draw_wins.c index c32d8b4..9efc8c9 100644 --- a/src/draw_wins.c +++ b/src/draw_wins.c @@ -10,7 +10,7 @@ #include "map.h" #include "main.h" -static void draw_map_objects (void *, struct Map *, struct Win *); +static void draw_map_objects (struct World *, struct MapObj *, struct Map *, struct Win *); extern void draw_with_linebreaks (struct Win * win, char * text, uint16_t start_y) { // Write text into window content space.
