现在有了基本地形类型，您可以想象得到接下来需要做什么：为每一行创建一个地图图像块数组。

Now that we have basic terrain types, you can imagine what comes next: we create an array of map tiles for each row.

我们可以设置复杂规则来控制如何生成地形，但是现在，从简单的内容开始：向数组中添加四个最相邻的图像块的地形类型，然后再随机获取。

We can set up complex rules to govern how terrain is generated, but for now, start with something simple: Add the terrain types of the four closest tiles to the array before picking them randomly.

在崎岖多石的地形下面，埋藏着岩石和化石，这有趣地说明远古时代的大陆板块碰撞，形成了现在的地貌、气候和植被。

The rocks and fossils buried in this rugged landscape tell an intriguing story of an ancient collision that shaped the modern topography, climate, and plant life.
