Reindeer tender (javascript) - help!

Only one reindeer goes to a pen, and sometimes it’s a sleeping reindeer the just moves to another pen.
I can’t understand what’s wrong, please help. Here’s my code:

var penPositions = [ {"x":20,"y":24}, {"x":28,"y":24}, {"x":36,"y":24}, {"x":44,"y":24}, {"x":52,"y":24} ];

// Use this array to keep track of each pen's reindeer.
var penOccupants = [ null, null, null, null, null ];

// And this array contains our reindeer.
var friends = hero.findFriends();

// Figure out which reindeer are already in their pens.
var reindeer = null;
for (var deerIndex = 0; deerIndex < friends.length; deerIndex++) {
    reindeer = friends[deerIndex];
    // For each position check if it matches a reindeer.
    for (var penIndex = 0; penIndex < penPositions.length; penIndex++) {
        var penPos = penPositions[penIndex];
        if (penPos.x == reindeer.pos.x && penPos.y == reindeer.pos.y) {
            // Put the reindeer in occupants at penIndex
            penOccupants[penIndex] = reindeer;
            // Remove the reindeer from the friends array.
            // break out of the inner loop here:

// Assign the remaining reindeer to new positions.
for (deerIndex = 0; deerIndex < friends.length; deerIndex++) {
    // If the reindeer is null, use continue:
    if (friends[deerIndex] === null) {
    // Look for the first pen with nothing.
    for (var occIndex = 0; occIndex < penOccupants.length; occIndex++) {
        // If there is nothing, the pen is open:
        if (penOccupants[occIndex] === null) {
            // Put the reindeer in the occupants array.
            penOccupants[occIndex] = reindeer;
            // Command the reindeer to move to the pen.
            hero.command(reindeer, "move", penPositions[occIndex]);
            // break out early so we don't reassign:

Hi foxfire,

It took me a while to figure this one out!

When you start the second main for loop to assign the reindeer to new positions, you need to tell the code what the variable ‘reindeer’ is again. Otherwise it just keeps it set to what it was before, and the hero tries to assign that one animal to all three positions :smile:.



@jka2706 thank you soooo much! :star_struck:
It worked and I’m shocked :open_mouth: I’ve been stuck in this level for a lot of time
