### Drone.dancefloor() method
|
|
Create an animated dance floor of colored tiles some of which emit light.
|
|
The tiles change color every second creating a strobe-lit dance-floor effect.
|
|
See it in action here [http://www.youtube.com/watch?v=UEooBt6NTFo][ytdance]
|
|
|
|
#### Parameters
|
|
|
|
* width - how wide the dancefloor should be (optional: default 5)
|
|
* length - how long the dancefloor should be (optional: default 5)
|
|
* duration - the time duration for which the lights should change (optional: default 30 seconds)
|
|
|
|
#### Example
|
|
|
|
At the in-game prompt you can create a dancefloor by looking at a block and typing:
|
|
|
|
```javascript
|
|
/js dancefloor()
|
|
```
|
|
|
|
Alternatively you can create a new Drone object from a Player or Location object and call the dancefloor() method.
|
|
|
|
```javascript
|
|
var d = new Drone(player);
|
|
d.dancefloor();
|
|
```
