Hands-on Rust

Wrap-Up

In this chapter, you implemented fields of view for the player and the monsters. You restricted map rendering to what the player can see, and limited monsters to chasing the player only if they can see them. This has enabled more tactical play, and made running to hide a valid option for the player. You also gave the player a memory of where they’ve been, and learned how to tint rendered tiles with a color.

In the next chapter, you’ll add difficulty to the game by further randomizing monster spawns. You’ll combine this with new ways to generate maps to create a much more tactically varied game. You’ll also learn how to theme your maps, varying the look and feel of your dungeons.
