t’s a bug?

Level is usual day . It’s in Backwoods Forest

while (true) {
    var enemy = hero.findNearestEnemy();
    // With AND, the type is only checked if enemy exists.
    if (enemy && enemy.type == "munchkin") {
        hero.attack(enemy);
    }
    // Find the nearest item.
    let item = hero.findNearestItem();
    let pos = item.pos;
    let posX = pos.x;
    let posY = pos.y;
    // Collect item if it exists and its type is "coin".
    if(item && item.type == "coin"){
     hero.moveXY(posX, posY);   
    }
}

I don’t know JavaScript but you need to post your code and tell us what level this is.

I think you have to check if there is an item first.

@milton.jinich no thats not the reason. Its because I joined a class do you see the back to classroom button. But I am emailing the support right now to unlink my account from the classroom

The same code . But it’s code is working

while (true) {
    var item = hero.findNearestItem();
    var distance = hero.distanceTo(item);
    // If the item's type is "gem"
    // OR the distance to the item less than 20 meters:
    let pos = item.pos;
    let x = pos.x;
    let y = pos.y;
    if(item.type == "gem" || distance < 20){
        // Move to item's position.
        hero.moveXY(x, y);
    }
}

It might take them a while to respond to the email because they work on monday to friday.
But this is getting off topic so its fine i will figure it out later

15

Can you delete your code if it is a sulution please

16

i deleted my code. But i think it’s a BUG.

17

It is not a bug, if you can pass the level with no errors, it is not a bug.

You must almost copy the code given in the default code:

while (true) {
    let enemy = hero.findNearestEnemy();
    // With AND, the type is only checked if enemy exists.
    if (enemy && enemy.type == "munchkin") {
        hero.attack(enemy);
    }
    // Find the nearest item.
    let item = hero.findNearestItem();
    // Collect item if it exists and its type is "coin".
    if (item &&  item.type == "coin")
        // put here your code for moving to the item
       //  use moveXY or move() if you have more advanced boots 
}

But the most important lesson from this code is that
@Deadpool198, @jka2706 and so on…
We can use now let and probably other a little bit more advanced features of java script without superfluous and annoying warnings and false errors
