Workshop › Puzzle Bobble-style Bubble Shooter › Step 11 of 31

Fly

What we are doing

Every frame the flying bubble moves by its velocity. update does it, and the loop calls it before draw.

```js
function update() {
  if (!shot) return
  shot.x += shot.vx
  shot.y += shot.vy
}

  update()
```

What it means

• Nothing flying: nothing to do. Otherwise add the velocity to the position.

Your turn

1. Above const clampAim ... write update, with an empty line after it.
2. In loop, call update() before draw().
