Prerequisites
Before we proceed, ensure that Scala is installed on your system. If not, you can download and install it from the official Scala website.
Let's Begin!
Step 1: Setting Up the Project
Start by creating a new Scala project or file in your preferred development environment. You can name the file TextGridGame.scala for organization.
Step 2: Import Required Libraries
import scala.io.StdIn
We'll begin by importing the StdIn module, which facilitates input reading from the console.
Step 3: Defining the Main Object
object TextGridGame {
// Your code will go here
}
Define the main object for our game as TextGridGame.
Step 4: Setting Up Initial Parameters
def main(args: Array[String]): Unit = {
val gridSize = 5
val playerMarker = "P"
val emptyCellMarker = "."
var playerX = gridSize / 2
var playerY = gridSize / 2
var grid = Array.ofDim[String](gridSize, gridSize)
for (i <- 0 until gridSize; j <- 0 until gridSize) {
grid(i)(j) = emptyCellMarker
}
grid(playerY)(playerX) = playerMarker
// Your code will go here
}
Set up initial parameters for the game, such as grid size, player marker, and empty cell marker. Initialize the player's starting position and create the initial grid.
Step 5: Printing the Grid
def printGrid(): Unit = {
for (i <- 0 until gridSize) {
for (j <- 0 until gridSize) {
print(grid(i)(j) + " ")
}
println()
}
}
Define a function, printGrid(), to display the current grid state.
Step 6: Updating the Grid
def updateGrid(): Unit = {
for (i <- 0 until gridSize; j <- 0 until gridSize) {
grid(i)(j) = emptyCellMarker
}
grid(playerY)(playerX) = playerMarker
}
Create the updateGrid() function to keep the grid up-to-date after each movement.
Step 7: The Game Loop
var continueGame = true
while (continueGame) {
printGrid()
val input = StdIn.readLine("Enter direction (w/a/s/d to move, q to quit): ").toLowerCase
input match {
// Your code for handling movement and quitting will go here
}
updateGrid()
println("\n" * 10) // Clear the console
}
}
Implement a game loop using a while loop. Within this loop, display the grid, collect player input for movement, manage movement and quitting, update the grid, and clear the console for a cleaner interface.
Step 8: Handling User Input
case "w" =>
if (playerY > 0) playerY -= 1
case "a" =>
if (playerX > 0) playerX -= 1
case "s" =>
if (playerY < gridSize - 1) playerY += 1
case "d" =>
if (playerX < gridSize - 1) playerX += 1
case "q" =>
continueGame = false
println("Thanks for playing!")
case _ =>
println("Invalid input. Use w/a/s/d to move or q to quit.")
Inside the game loop, handle user input. Depending on the entered key (w, a, s, d, or q), update the player's position or decide to quit the game.
Conclusion
In this guide, you've unlocked the realm of Scala game development by creating a captivating text-based game within a 2D grid. From mastering user input to orchestrating grid updates and game loops, you've gained essential programming insights. This creative journey marks just the starting point in the dynamic world of game programming.
