/**

|
* This mod lets you load and run javascript to build structures which would otherwise be tedious.
|
|
* Build road networks, rows of houses, factories and sky-scrapers. ScriptCraft takes building to a whole new level
|
|
* by making it easy to create javascript scripts that do the building for you.
|
|
* The following code creates a simple cottage at the crosshair location or the player's current location...
|
|
* load("./drone.js");
|
|
* var drone = new Drone();
|
|
* drone.box0(48,7,6,2) // 4 walls
|
|
* .right(3).door() // a door front-center
|
|
* .left(2).box(102) // windows left and right of door
|
|
* .right(4).box(102) //
|
|
* .home().up(2).prism0(53,7,6); // a gable roof
