They wander

What we are doing

A far enemy wanders: one pixel a frame in its direction, and every now and then (or when it bumps into a wall) it picks a new random direction. move tells us when it bumped.

```js
} else {
  // Far: wander, turning at random now and then or when a wall is in the way.
  e.turnIn -= 1
  const stuck = move(e, e.dir[0], e.dir[1])
  if (stuck || e.turnIn <= 0) {
    e.dir = Object.values(DIRS)[Math.floor(Math.random() * 4)]
    e.turnIn = 40 + Math.floor(Math.random() * 60)
  }
}
```

What it means

• turnIn counts down the frames until the next turn.
• Object.values(DIRS) is the list of the four directions; a random one is picked.
• The next turn comes in 40 to 99 frames, so each enemy has its own rhythm.

Your turn

In the chase block, add an else that wanders when far.
