{r.oguelike}

A tile-based roguelike toy for R's console.

This is a proof-of-concept. Read more in the blogposts. Suggest improvements or fixes in the issues.

You can install {r.oguelike} from GitHub via {remotes} (CRAN packages {crayon}, {keypress} and {sonify} are also installed):

if (!require(remotes)) install.packages("remotes")
remotes::install_github("matt-dray/r.oguelike")

You could also launch an instance of RStudio in the browser with {r.oguelike} preinstalled, thanks to Binder.

Use start_game() to begin. See ?start_game for details on how to adjust the starting parameters.

r.oguelike::start_game(
  max_turns  = 25,
  iterations = 3,
  n_row      = 15,
  n_col      = 20,
  n_rooms    = 4
)

The console will clear and then you’ll see a dungeon map, an inventory bar, a status message and a prompt for player input. Output will appear in colour if your console supports it.

Press W, A, S or D then Enter to move, 1 to eat apple, 0 to exit
Input:

The dungeon map (# for walls and . for floor tiles) is procedurally-generated and the placement of objects (@ is the player, E is an enemy, $ is gold and a is an apple) is randomised.

To move the player character (@), type one of WASD at the prompt and hit Enter. If your terminal supports {keypress} (RStudio doesn't) then you'll be able to type a single arrow key instead.

After instructing the player character to move down, for example, the screen refreshes to show @ is in a new location and the status message has been updated. Simple sound effects will play depending on the outcome of the move.

Moved down
Input:

Also note that the enemy's (E) position has changed and it's heading in your direction...

What now? Collect the gold ($). Auto-battle the chasing enemy (E). Collect an apple (a) for your inventory, then eat it with a keypress input of 1 to replenish health. You’ll die if you run out of HP or if you reach the maximum number of turns allowed (T). You can quit the game with 0.
