what’s the problems of my code? The soldiers did’t move until the peasant was shot dead

```
def findSoldierOffset(soldiers, i):
soldier = soldiers[i]
angle = i * 360 / len(soldiers)
return radialToCartesian(5, angle)
# This function does the math to determine the offset a soldier should stand at.
def radialToCartesian(radius, degrees):
radians = Math.PI / 180 * degrees
xOffset = radius * Math.cos(radians)
yOffset = radius * Math.sin(radians)
return {"x": xOffset, "y": yOffset}
peasant = hero.findByType("peasant")[0]
# Use findByType to get an array of your soldiers.
soldiers = hero.findByType("soldiers")
while True:
# Use a for-loop to iterate over range(len(soldiers)).
for i in range(len(soldiers)):
# Find the offset for a soldier.
offset = findSoldierOffset(soldiers, i)
# Add the offset.x and offset.y to the peasant's pos.x and pos.y.
x = peasant.pos.x + offset.x
y = peasant.pos.y + offset.y
# Command the soldier to move to the new offset position.
hero.command(soldiers[i], "move", {'x':x, 'y':y})
# The hero should keep pace with the peasant!
hero.move({"x": hero.pos.x + 0.2, "y": hero.pos.y})
```
