We are going to be making a simple guessing game

Creating a guessing game

Introduction

We will be learning how to create a simple guessing game in Versace. This will be a simple game where the user will guess a number between 1 and 10. If the user guesses the correct number, they win. If they guess the wrong number, they try again. We will be using the in to get the user's guess and the out to display the result.

Creating the game

We first need the random module, we can include it in our program, by using include, we will be including it as random_int:

include "randint" from "random" as "random_int";

We now need to create the public init function, this will run first to initialize the program:

public init() {
    // code
}

All of our code from now will be inside the init function. Our next step is to generate the random number, we can do this by using the random_int function:

int number = random_int(1, 10);

Now we need to create a while loop, this will be used to keep the game running until the user guesses the correct number:

while (true) {
    // code
}

Now we need to get the user's guess, we can do this by using the in function (This goes inside the while loop):

in guess << "Enter a guess: " << int << bright_red;

Now we need to check if the user guessed the correct number, we can do this by using an if statement:

if (guess == number) {
    // code
}

If the user guessed the correct number, we need to display a message, we can do this by using the out function (This goes inside the if statement):

out << "You guessed it! The number was" << number << "." << bright_blue;

Now we need to break out of the while loop, we can do this by using the break keyword:

break;

If the user guessed the wrong number, we need to display a message, we can do this by using the out function (This goes inside the while loop):

out << "You guessed wrong! Try again." << bright_red;

Now we can run our program by going to the terminal and typing versace guessing_game.vs:

$ versace guessing_game.vs

Conclusion

We have now created a simple guessing game in Versace. We have learned how to use the in and out functions, we have also learned how to use the include keyword and the random_int function. We have also learned how to use the while loop and the if statement. We have also learned how to use the break keyword.

Full Game Code (made a little better)

include "randint" from "random" as "random_int";

public init() {
    int number = random_int(1 | 10);
    out << "This is a guessing game. I'm thinking of a number between 1 and 10." << bright_green;
    out << "Try to guess it in as few attempts as possible." << bright_green;
    while (true) {
        in guess << "Enter a guess: " << int << bright_red;
        if (guess == number) {
            out << "You guessed it! The number was" << number << "." << bright_blue;
            break;
        } else if (guess < number) {
            out << "Your guess is too low." << bright_red;
        } else {
            out << "Your guess is too high." << bright_red;
        }
    }
}
