### Drone.sphere() method
|
|
|
|
Creates a sphere.
|
|
|
|
#### Parameters
|
|
|
|
* block - The block the sphere will be made of.
|
|
* radius - The radius of the sphere.
|
|
|
|
#### Example
|
|
|
|
To create a sphere of Iron with a radius of 10 blocks...
|
|
|
|
sphere( blocks.iron, 10);
|
|
|
|
|
|
|
|
Spheres are time-consuming to make. You *can* make large spheres (250 radius) but expect the
|
|
server to be very busy for a couple of minutes while doing so.
