From 9ca761b06534ed191b0624a6c7049db296997a73 Mon Sep 17 00:00:00 2001 From: celestar Date: Sat, 16 Jul 2005 23:47:37 +0000 Subject: (svn r2595) -Codechange: Introduced "IsSteepTileh" to find whether a tile is steep (i.e. spans two height levels) and use it throughout the code. -Codechange: Add CanBuildDepotByTileh to find if a tile is suitable to build a depot on it.
