Workshop › Bomberman-style Arena › Step 15 of 42

One bomb at a time

What we are doing

The player may only have maxBombs bombs down at once, one to begin with. Power-ups will raise it later.

```js
let maxBombs

  maxBombs = 1

function dropBomb() {
  if (bombs.length >= maxBombs) return
```

What it means

• bombs.length is how many bombs are down; with as many as allowed, dropBomb leaves at once.

Your turn

1. Under let held write let maxBombs; in reset, under held = [], write maxBombs = 1.
2. Write the if as the first line of dropBomb.
