From 885fd2b15c1ae9a1422f82b8bcdd9d1a287c3aa6 Mon Sep 17 00:00:00 2001 From: darkvater Date: Sat, 29 Jan 2005 18:22:07 +0000 Subject: [PATCH] (svn r1720) - Fix: signed/unsigned warnings. Tile which is incremented/decremented every time until suitable ground is found is compared to the direction it is going in. If this wraps, return error. For this treat the tile itself as a TileIndexDiff --- ai.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/ai.c b/ai.c index 598ab4d4a8..11e7c0cb24 100644 --- a/ai.c +++ b/ai.c @@ -1962,7 +1962,7 @@ static inline void AiCheckBuildRailBridgeHere(AiRailFinder *arf, TileIndex tile, // Allow bridges directly over bottom tiles flag = arf->ti.z == 0; for(;;) { - if (tile_new < -TileOffsByDir(dir2)) return; // Wraping around map, no bridge possible! + if ((TileIndexDiff)tile_new < -TileOffsByDir(dir2)) return; // Wraping around map, no bridge possible! tile_new = TILE_MASK(tile_new + TileOffsByDir(dir2)); FindLandscapeHeightByTile(&arf->ti, tile_new); if (arf->ti.tileh != 0 || arf->ti.type == MP_CLEAR || arf->ti.type == MP_TREES) { @@ -2851,7 +2851,7 @@ static inline void AiCheckBuildRoadBridgeHere(AiRoadFinder *arf, TileIndex tile, // Allow bridges directly over bottom tiles flag = arf->ti.z == 0; for(;;) { - if (tile_new < -TileOffsByDir(dir2)) return; // Wraping around map, no bridge possible! + if ((TileIndexDiff)tile_new < -TileOffsByDir(dir2)) return; // Wraping around map, no bridge possible! tile_new = TILE_MASK(tile_new + TileOffsByDir(dir2)); FindLandscapeHeightByTile(&arf->ti, tile_new); if (arf->ti.tileh != 0 || arf->ti.type == MP_CLEAR || arf->ti.type == MP_TREES) {
