You are using x & y, but where do you set them??  
The directions say “build a fence 10m below/above it.” but I see “±4” not ±10.  
The directions suggest you check where the yak is not how far away.

```python
if (this.distanceTo(yak) < y) {
            this.buildXY("fence", x, y - 4);

```

If you are unsure how to set x & y look at the else clause…  
(Should you build the fence above/below you (this) or the yak (yak)?)
