// Interface
// =========
//
// Please read the following section to understand what a Minecraft Drone can do.
//
var Drone = {
//
// creating a new drone
// ====================
//
// Drones can be created in 2 ways...
//
// [1] d = new Drone()
// This will create a new Drone. If the cross-hairs are pointing
// at a block at the time then, that block's location becomes the drone's
// starting point.
// If the cross-hairs are _not_ pointing at a block, then the drone's starting
// location will be 2 blocks directly in front of the player.
//
// [2] d = new Drone(x,y,z,direction)
// This will create a new Drone at the location you specified using x, y, z
// In minecraft, the X axis runs west to east and the Z axis runs north to south.
// The direction parameter says what direction you want the drone to face:
// 0 = east, 1 = south, 2 = west, 3 = north.
// If the direction parameter is omitted, the player's direction is used instead.
//
// movement
// ========
//
// Drones can move freely in minecraft's 3-D world. You control the Drone's movement using
// any of the following methods..
//
// move up - n is the number of blocks you want to move (default 1)
up: function(n){},
// move down - n is the number of blocks you want to move (default 1)
down: function(n){},
// move left - n is the number of blocks you want to move (default 1)
left: function(n){},
// move right - n is the number of blocks you want to move (default 1)
right: function(n){},
// move forward - n is the number of blocks you want to move (default 1)
fwd: function(n){},
// move backwards - n is the number of blocks you want to move (default 1)
back: function(n){},
// to change direction - n is the number of turns right you want to make (default 1)
// turns are always clock-wise. If the drone is facing north, then drone.turn() will
// make the turn face east. If the drone is facing east then drone.turn(2) will make the
// drone turn twice so that it is facing west.
//
turn: function(n){},
// markers
// =======
//
// Markers are useful when your Drone has to do a lot of work. You can set a check-point
// and return to the check-point using the move() method.
// if your drone is about to undertake a lot of work - e.g. building a road, skyscraper or forest
// you should set a check-point before doing so if you want your drone to return to its current location.
// e.g:
//
// drone.chkpt('town-square');
// for (i = 0; i< 100; i++){
// drone.fwd(12).box(6);
// }
// drone.move('town-square');
//
// A 'start' checkpoint is automatically created when the Drone is first created.
//
chkpt: function(checkpoint_name){},
move: function(checkpoint_name){},
// building
// ========
//
// the box() method is the main method for building things.
// parameters
// ----------
// b - the block id - e.g. 6 for an oak sapling or '6:2' for a birch sapling.
// w - the width of the structure (optional - default value is 1)
// h - the height of the structure (optional - default value is 1)
// d - the depth of the structure - NB this is *not* how deep underground the structure lies - this is
// how far away (depth of field) from the drone the structure will extend.
// (optional - default value is 1)
// e.g:
// To create a stone structure 5 blocks wide, 8 blocks tall and 15 blocks long...
//
// drone.box(48, 5, 8, 15);
//
// To create an oak tree...
// (we can't control the dimensions of a tree since it's a natural object in minecraft)
//
// drone.box(6);
//
box: function(b,w,h,d){},
//
// like box but empties out the inside - ideal for buildings.
//
box0: function(b,w,h,d){},
prism: function(b,w,d){},
prism0: function(b,w,d){},
door: function(b){},
// signs must use block 63 (stand-alone signs) or 68 (signs on walls)
// s can be a string or an array of strings.
sign: function(s,b){}
};
//
// Implementation
// ==============
//
// There is no need to read any further unless you want to understand how the Drone object works.
