A moment of safety

What we are doing

After losing a life the player is safe for 120 frames (two seconds), and blinks to show it. Only when safe is back at 0 can flames hurt again.

```js
let safe // frames of invincibility after losing a life

  safe = 0

  safe = 120

  if (safe > 0) safe -= 1
  else if (inFlames(player)) hurt()

  if (safe % 10 < 5) drawCircle(player, '#f8fafc', 12)
```

What it means

• hurt sets safe to 120; update counts it down, and only checks the flames when it is 0.
• The player is drawn only while safe % 10 < 5, which switches every 5 frames. At 0 it is always drawn.

Your turn

1. Under let lives write let safe; in reset, under lives = 3, write safe = 0.
2. At the end of hurt, write safe = 120.
3. In update, replace the flame line with the two safe lines.
4. In draw, put if (safe % 10 < 5) in front of the player's drawCircle.
