Unity 5: 2D Random Map Generation

Learn how to build randomly generated 2D maps for role-playing and real-time strategy games with Unity 5.

Learn how to build randomly generated 2D maps for role-playing and real-time strategy games with Unity 5. Jesse Freeman focuses on the basics of random map generation by teaching you how to create island-based terrains, and works his way up into more advanced techniques such as resizing the map, decorating it, and eventually creating large-scale maps with individual continents. He'll add trees, mountains, dungeons, and castles to make the map more fun to explore. He'll also teach you how to create a camera script that scrolls around the map with the mouse, and set up autotiling to give the map's coastlines a more organic look. In the end, Jesse will show you how to build an authentic 8-bit style map generation tool—perfect for your next 2D RPG game.
