From ea4ba47662269fef9ae589c285659ee2f06a0b17 Mon Sep 17 00:00:00 2001 From: Simon Tatham Date: Fri, 28 Oct 2022 22:35:22 +0100 Subject: [PATCH] Loopy: adjust clip rectangle for new line thickness. It would have helped in the previous commit if I'd tried actually _playing_ the game, not just admiring it in its initial state. When I did, I found that lines weren't being fully overdrawn, which turned out to be because the clip rectangle was being set too narrow. --- loopy.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/loopy.c b/loopy.c index 61a79c2..b7fb296 100644 --- a/loopy.c +++ b/loopy.c @@ -3231,10 +3231,10 @@ static void edge_bbox(game_drawstate *ds, grid *g, grid_edge *e, grid_to_screen(ds, g, x1, y1, &x1, &y1); grid_to_screen(ds, g, x2, y2, &x2, &y2); /* Allow extra margin for dots, and thickness of lines */ - xmin = min(x1, x2) - 2; - xmax = max(x1, x2) + 2; - ymin = min(y1, y2) - 2; - ymax = max(y1, y2) + 2; + xmin = min(x1, x2) - (ds->tilesize + 15) / 16; + xmax = max(x1, x2) + (ds->tilesize + 15) / 16; + ymin = min(y1, y2) - (ds->tilesize + 15) / 16; + ymax = max(y1, y2) + (ds->tilesize + 15) / 16; *x = xmin; *y = ymin;
