### Copy & Paste using Drone
|
|
|
|
A drone can be used to copy and paste areas of the game world.
|
|
|
|
### Drone.copy() method
|
|
|
|
Copies an area so it can be pasted elsewhere. The name can be used for
|
|
pasting the copied area elsewhere...
|
|
|
|
#### Parameters
|
|
|
|
* name - the name to be given to the copied area (used by `paste`)
|
|
* width - the width of the area to copy
|
|
* height - the height of the area to copy
|
|
* length - the length of the area (extending away from the drone) to copy
|
|
|
|
#### Example
|
|
|
|
drone.copy('somethingCool',10,5,10 ).right(12 ).paste('somethingCool' );
|
|
|
|
### Drone.paste() method
|
|
|
|
Pastes a copied area to the current location.
|
|
|
|
#### Example
|
|
|
|
To copy a 10x5x10 area (using the drone's coordinates as the starting
|
|
point) into memory. the copied area can be referenced using the name
|
|
'somethingCool'. The drone moves 12 blocks right then pastes the copy.
|
|
|
|
drone.copy('somethingCool',10,5,10 )
|
|
.right(12 )
|
|
.paste('somethingCool' );
