// You must escort a powerful magical ring back to town to be studied.
// The goal is to escape, not fight. More ogres lurk in the surrounding mountains!
// Make a circle of soldiers around the peasant!
// We give you two functions to help with this:
// findSoldierOffset figures out the position a soldier should stand at in relation to the peasant.
// The first argument 'soldiers' should be an array of your soldiers.
// The second argument 'i' is the index of the soldier (in soldiers) you want to find the position for.
function findSoldierOffset(soldiers, i) {
var soldier = soldiers[i];
var angle = i * 360 / soldiers.length;
return radialToCartesian(5, angle);
}
// This function does the math to determine the offset a soldier should stand at.
function radialToCartesian(radius, degrees) {
var radians = Math.PI / 180 * degrees;
var xOffset = radius * Math.cos(radians);
var yOffset = radius * Math.sin(radians);
return {x: xOffset, y: yOffset};
}
var peasant = hero.findByType("peasant")[0];
// Use findByType to get an array of your soldiers.
while(true) {
// Use a for-loop to iterate over your array of soldiers.
var soldiers = hero.findByType("soldier");
for (var i = 0; i < soldiers.length; i ++) {
var soldier = soldiers[i];
var offset = findSoldierOffset(soldier, i);
hero.command(soldier, "move", {'x': offset.pos.x + peasant.pos.x, 'y': offset.pos.y + peasant.pos.y});
}
// Find the offset for a soldier.
// Add the offset.x and offset.y to the peasant's pos.x and pos.y.
// Command the soldier to move to the new offset position.
// The hero should keep pace with the peasant!
hero.move({x: hero.pos.x + 0.2, y: hero.pos.y});
}
```

i get error at this part “offset.pos.x” and it say cannot have property x of underfined
