Flames hurt

What we are doing

Now the flames are dangerous: standing in one costs a life and sends the player back to the start. "In a flame" means a flame on the player's tile, the nearest tile to where it is.

```js
let lives

  lives = 3

const inFlames = (m) => {
  const t = tileOf(m)
  return flames.some((f) => f.r === t.r && f.c === t.c)
}

function hurt() {
  lives -= 1
  player = { x: 1, y: 1, target: null }
}

  if (inFlames(player)) hurt()
```

What it means

• An arrow function with several lines needs { } and a return.
• flames.some(...) asks whether at least one flame is on that tile.
• hurt takes a life and puts a fresh player back at the start.

Your turn

1. Under let power write let lives; in reset, under power = 2, write lives = 3.
2. Above function update() { write inFlames and hurt.
3. At the end of update, write the if (inFlames(player)) line.
