Workshop › Bomberman-style Arena › Step 21 of 42

Crates burn

What we are doing

A crate in the way catches fire: it becomes floor, and the arm stops there. That is how you open the way through the arena.

```js
flames.push({ r, c, time: FLAME_TIME })
if (grid[r][c] === '+') {
  grid[r][c] = ' '
  break
}
```

What it means

• The crate's tile gets its flame first, then becomes floor, and break ends the arm.

Your turn

In explode, under the flames.push({ r, c, ... }) line inside the loop, write the if.
