Few questions... [JavaScript]

1

Alright bear with me because this is EXTREMELY long on me trying to figure stuff out but in conclusion I came up with a few questions!

/*
while(true) {
    var friend = hero.findNearest(hero.findFriends());
    hero.moveXY(friend.pos.x, friend.pos.y -6);
}
*/  

/*while (true) {
var names = ["Tharin", "Hattori"];
hero.moveXY(names[0].pos.x, names[1].pos.y);
}*/

/*while (true) {
    var friends = hero.findFriends();
    var xi = null;
    var yi = null;
    var i = 0;
    var friend = friends[i];
    if (friend && friend.pos.x == hero.pos.x) {
        xi = friend.pos.x;
    }
    if (friend && friend.pos.y == hero.pos.y) {
        yi = friend.pos.y; 
}

hero.moveXY(xi, yi);
}
*/

/*var friends = hero.findFriends();
var i = 0;
var friend = friends[i];

while (i < friends.length){
    friend = friends[i];
    hero.say(friend);
    i++;
}
*/
/* [0]"Amara", [1]"Senick", [2]"Pender", [3]"Kleene", [4]"Tharin", [5]"Omarn", [6]"Hattori", [7]"Anya", [8]"Hushbaum", [9]"Naria" (possibly try moving in sync with these)
*/

/*
var friends = hero.findFriends();
var i = 0;
var friend = friends[i];

function iy() {
while (i < friends.length) {
    friend = friends[i];
    if (friend.pos.x == hero.pos.x) {
        return friend.pos.x;
    } else {
    i++;
    }
}
}

i = 0;
function ix() {
while (i < friends.length) {
    friend = friends[i];
    if (friend.pos.y == hero.pos.y) {
        return friend.pos.y;
    } else {
    i++;
    }
}
}
while (true){
var fx = ix();
var fy = iy();
hero.moveXY(fx, fy);
}
*/


/* [0]"Amara", [1]"Senick", [2]"Pender", [3]"Kleene", [4]"Tharin", [5]"Omarn", [6]"Hattori", [7]"Anya", [8]"Hushbaum", [9]"Naria" (possibly try moving in sync with these)
*/

/*
while (true) {
var friends = hero.findFriends();
var i = 0;

hero.moveXY(friends[4].pos.x, friends[6].pos.y);
}
*/
/* 
    var friend = hero.findNearest(hero.findFriends());
    var offsetX = friend.pos.x - hero.pos.x;
    var offsetY = friend.pos.y - hero.pos.y;
while(true) {

    hero.move({'x': friend.pos.x - offsetX, 'y': friend.pos.y - offsetY});
}
*/
var friend = hero.findNearest(hero.findFriends());
var yi = friend.pos.y - hero.pos.y;
while(true) {
   // hero.move({'x':friend.pos.x, 'y': friend.pos.y - yi});
   hero.moveXY(friend.pos.x, friend.pos.y - yi);
}
  1. Alright so first of all I realize I wasnā€™t accounting for the offset and thatā€™s why many of my attempts failed. in previous levels I noticed arrays set by names, so for example
/*while (true) {
var names = ["Tharin", "Hattori"];
hero.moveXY(names[0].pos.x, names[1].pos.y);
}*/

May I ask what I did wrong in defining Tharin and Hattori in their own variables? Is it because I didnā€™t find out if they exist? or didnā€™t use a find function to declare Tharin and Hattori?

  1. Next is there any easier way to figure out why exactly each number is in a array short of doing this:
/*var friends = hero.findFriends();
var i = 0;
var friend = friends[i];

while (i < friends.length){
    friend = friends[i];
    hero.say(friend);
    i++;
}
*/
/* [0]"Amara", [1]"Senick", [2]"Pender", [3]"Kleene", [4]"Tharin", [5]"Omarn", [6]"Hattori", [7]"Anya", [8]"Hushbaum", [9]"Naria" (possibly try moving in sync with these)
*/

and finding out what each number would correlate to name wise?

  1. How do I get a function to return a number?
function iy() {
while (i < friends.length) {
    friend = friends[i];
    if (friend.pos.x == hero.pos.x) {
        return friend.pos.x;
    } else {
    i++;
    }
}
}

later on I set function iy() to a variable but it wasnā€™t returning a numberā€¦ Iā€™ve looked back on some of my previous code examples but couldnā€™t find a point of reference (maybe I overlooked it)

  1. Iā€™ve seen before code listed as spoilers where you have to click to expand it, how do I go about doing that?

That about sums up my questions, thank you in advance!

#1
The array names is assigned to some string or text,the function hero.moveXY need x, y coordinates
If you say ā€œTharinā€.pos.x you are asking to get the x coordinates of some text, there is no coordinates for that. You need to get the object Tharin and Hattori first. And for that youā€™ll have no choice to do manipulations in friends
It wonā€™t work with hero.move() either because hero.move need also an object

#2
I donā€™t really understand what you are asking, but if you aim for a particular character you can always ask in your loop if friend.id == ā€œnameā€

#3
the problem here is that you are using a lot of variables that is not defined inside the function youā€™ll need to set those variables as arguments in your function.
For example, you are using the array friends and the variable i. But the function donā€™t know what is friends neither what is i
So you need to put arguments inside the function:
iy(a, b)
while(a < b.length) etc.
(a, b) is an argument. IMPORTANT: an argument has no value. You give them value only when you call the function.
When you call the function in your code write something like that:
iy(friends, i)

Thank you Gabriel! Iā€™ll give your answers a go when I get a chance =) Iā€™m finally in the Cloudrip Mountains! 13/109 so far (I just realized you probably knew this because of the code I am inquiring about lol)
