I have a function that randomly selects a monster from an object. Here's the function:
var travel = function(direction) {
var newRoom = rooms[currentRoom.paths[direction]];
if (!newRoom) {
$("<p>You can't go that way.</p>").properDisplay();
}
else {
currentRoom = newRoom;
$("<p>You are now in the " + currentRoom.name + " Room.</p>").properDisplay();
if (currentRoom.hasMonsters) {
function pickRand() {
var monsterArray = Object.keys(monsters);
var randomKey = Math.floor(Math.random() * monsterArray.length);
return $("<p>Holy Crap! There's a " + monsterArray[randomKey] + " in here!</p>").properDisplay();
}
pickRand();
}
}
};
Here's the object:
var monsters = {
zombie: {
hitPoints: 10,
loot: "magic knife"
},
skeleton: {
hitPoints: 15,
loot: "magic shield"
},
ghoul: {
hitPoints: 12,
loot: "magic helm"
}
};
It's set up to randomly select "Zombie", "Skeleton", or "Ghoul." Everything works fine. How do I take whatever was randomly selected and save it to a variable?
I've tried a couple things like:
var beast = pickRand();
and
var beast = monsterArray;
But no luck. What am I missing?
It looks like the problem is that you're returning the return value of the properDisplay
function.
If you used an array of monsters rather than a map you could store all of the monster information when you select a random one:
var monsters = [
{
name: 'zombie',
hitPoints: 10,
loot: "magic knife"
},
{
name: 'skeleton',
hitPoints: 15,
loot: "magic shield"
},
{
name: 'ghoul',
hitPoints: 12,
loot: "magic helm"
}
];
function pickRand(arr) {
var index = Math.floor(Math.random() * arr.length);
return arr[index];
}
var monster = pickRand(monsters);
Now that you have your monster you could display it:
$("<p>Holy Crap! There's a " + monster.name + " in here!</p>").properDisplay();
var beast = pickRand();
should totally work. You just need to assign the variable right when you call it?
var travel = function(direction) {
var newRoom = rooms[currentRoom.paths[direction]];
if (!newRoom) {
$("<p>You can't go that way.</p>").properDisplay();
}
else {
currentRoom = newRoom;
$("<p>You are now in the " + currentRoom.name + " Room.</p>").properDisplay();
if (currentRoom.hasMonsters) {
function pickRand() {
var monsterArray = Object.keys(monsters);
var randomKey = Math.floor(Math.random() * monsterArray.length);
return $("<p>Holy Crap! There's a " + monsterArray[randomKey] + " in here!</p>").properDisplay();
}
var beast = pickRand();
}
}
}
