This map isn't flat — it has 5 levels of elevation. Ocean and Grass start at level 0, but slopes and cliffs can move up or down a level. Low slopes go up 1 level, high slopes go up 2 levels. A road tile at level 3 needs to connect to another road tile at level 3, or a slope tile that transitions between levels. Get it wrong and you end up with roads that dead-end into cliff faces or rivers flowing uphill into the sky. The elevation axis turns a 2D constraint problem into a 3D one, and it's where a lot of the tile variety (and a lot of the solver failures) comes from.。业内人士推荐谷歌作为进阶阅读
