Extending Your Game World with Tile Maps

With a game like Val’s Revenge, players need to have a lot of room to explore. Although it’s possible to build a gigantic scene using one, two, or even three or more background images, there’s a more efficient and scalable way to create scenes worthy of exploration: tile maps.

Whether you’re building a side-scrolling platformer game or a top-down adventure game, tile maps give you greater control and flexibility over the landscape while also using less resources.

In this chapter, you’ll add two tile map nodes to Val’s Revenge, giving the player some much-needed room to explore the scene.
