Javascript Battleship Game












-1















I made a simple battleship game in javascript but there is not workimg correctly. I put the locations in an array and tried to delete guessed locations from that array by using splice method. But it alerts "MISS!" when i enter any number between 0 and 6.



Edit: I solved the problem by using parseInt method for promt.



var location1 = Math.floor(Math.random() * 5);
var location2 = location1 + 1;
var location3 = location2 + 1;

var locations = ;
locations.push([location1, location2, location3]);

var guess;
var hits = 0;
var guesses = 0;

var isSunk = false;

while (isSunk == false) {
guess = prompt("Enter your guess(0 - 6)");
if (guess < 0 || guess > 6) {
alert("Please enter a valid number!");
} else {
guesses++;

if (locations.indexOf(guess) > 0) {
locations.splice(locations.indexOf(guess), 1);
hits++;
alert("HIT!");
if (hits == 3) {
isSunk = true;
alert("You sank my battleship!");
}
} else {
alert("MISS!");
}
}
}

var stats = "You took " + guesses + " guesses to sink the battleship, which
means your shooting accuracy was " + (3 / guesses);
alert(stats);

    The .indexOf() test should be >= 0

    Also prompt() always returns a string.

  • @Pointy That's true but is javascript doing conversions between string and number automatically?

    Sometimes yes, sometimes no. The .indexOf method does === comparisons.
