From 5b0ab052105670986ec973f035b758add4d25481 Mon Sep 17 00:00:00 2001 From: jacob Date: Sat, 22 Oct 2005 18:07:56 +0000 Subject: [PATCH] Work around a couple of minor display issues with max bridges set to 4: - the highlighting for a set of 4 lines spilled outside the tile, so would leave white residue if undone; - the endpoints of sets of 4 lines were not completely overprinted by the circle of an island (at least on Windows), which was untidy. Fixed by reducing the gap width for groups of lines which wouldn't otherwise fit in a tile (only). git-svn-id: svn://svn.tartarus.org/sgt/puzzles@6421 cda61777-01e9-0310-a592-d414129be87e --- bridges.c | 45 +++++++++++++++++++++++---------------------- 1 file changed, 23 insertions(+), 22 deletions(-) diff --git a/bridges.c b/bridges.c index a3d342c..721d75f 100644 --- a/bridges.c +++ b/bridges.c @@ -2288,22 +2288,30 @@ static void game_free_drawstate(drawing *dr, game_drawstate *ds) #define OFFSET(thing) ((TILE_SIZE/2) - ((thing)/2)) -static void line_vert(drawing *dr, game_drawstate *ds, - int ox, int oy, int col, grid_type v) +static void lines_vert(drawing *dr, game_drawstate *ds, + int ox, int oy, int lv, int col, grid_type v) { - int lw = LINE_WIDTH; + int lw = LINE_WIDTH, gw = LINE_WIDTH, bw, i, loff; + while ((bw = lw * lv + gw * (lv+1)) > TILE_SIZE) + gw--; + loff = OFFSET(bw); if (v & G_MARKV) - draw_rect(dr, ox-lw, oy, lw*3, TILE_SIZE, COL_MARK); - draw_rect(dr, ox, oy, lw, TILE_SIZE, col); + draw_rect(dr, ox + loff, oy, bw, TILE_SIZE, COL_MARK); + for (i = 0; i < lv; i++, loff += lw + gw) + draw_rect(dr, ox + loff + gw, oy, lw, TILE_SIZE, col); } -static void line_horiz(drawing *dr, game_drawstate *ds, - int ox, int oy, int col, grid_type v) +static void lines_horiz(drawing *dr, game_drawstate *ds, + int ox, int oy, int lh, int col, grid_type v) { - int lw = LINE_WIDTH; + int lw = LINE_WIDTH, gw = LINE_WIDTH, bw, i, loff; + while ((bw = lw * lh + gw * (lh+1)) > TILE_SIZE) + gw--; + loff = OFFSET(bw); if (v & G_MARKH) - draw_rect(dr, ox, oy-lw, TILE_SIZE, lw*3, COL_MARK); - draw_rect(dr, ox, oy, TILE_SIZE, lw, col); + draw_rect(dr, ox, oy + loff, TILE_SIZE, bw, COL_MARK); + for (i = 0; i < lh; i++, loff += lw + gw) + draw_rect(dr, ox, oy + loff + gw, TILE_SIZE, lw, col); } static void line_cross(drawing *dr, game_drawstate *ds, @@ -2353,8 +2361,7 @@ static void lines_redraw(drawing *dr, game_state *state, game_drawstate *ds, game_ui *ui, int x, int y, grid_type v, int lv, int lh) { - int lw = LINE_WIDTH, bw; - int ox = COORD(x), oy = COORD(y), loff, i; + int ox = COORD(x), oy = COORD(y); int vcol = (v & G_FLASH) ?
