//
// creating a new drone
// ====================
//
2013-01-02 08:39:05 +01:00
// Drones can be created in 3 ways...
//
2013-01-02 08:40:32 +01:00
// [1] Calling any one of the methods listed below will return a Drone object. For example...
//
// /js var d = box(5)
//
// ... creates a 1x1x1 wooden block at the cross-hairs or player's location and returns a Drone
// object. This might look odd (if you're familiar with Java's Object-dot-method syntax) but all
// of the Drone class's methods are also global functions that return new Drone objects.
// This is short-hand for creating drones and is useful for playing around with Drones at the in-game
// command prompt. It's shorter than typing ...
//
// /js var d = new Drone().box(5)
//
// ... All of the Drone's methods return `this` (self) so you can chain operations together like this...
//
// /js var d = box(5).up().box(5,3,1,3).down().fwd(2).box(5).turn().fwd(2).box(5).turn().fwd(2).box(5)
//
2013-01-02 08:39:05 +01:00
// [2] /js d = new Drone()
2013-01-02 08:40:32 +01:00
//
// 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.
// TIP: Building always happens right and front of the drone's position...
//
// Plan View:
//
// ^
// |
// |
// D---->
//
// For convenience you can use a 'corner stone' to begin building.
// The corner stone should be located just above ground level.
// If the cross-hair is point at or into ground level when you create a new Drone(),
// then building begins at that point. You can get around this by pointing at a
// 'corner stone' just above ground level or alternatively use the following statement...
//
// /js d = new Drone().up()
//
// ... which will move the drone up one block as soon as it's created.
//
2013-01-02 08:39:05 +01:00
// [3] d = new Drone(x,y,z,direction)
2013-01-02 08:40:32 +01:00
//
// 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.
//
2013-01-02 08:40:32 +01:00
// When you load() the drone.js javascript file, a default `drone` Object is created at
// the cross-hair's or player's location.
//
// 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.
// An array of block ids can also be used in which case each block in the array
// will be placed in turn.
// 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(block,width,height,depth){},
//
// like box but empties out the inside - ideal for buildings.
//
box0: function(block,width,height,depth){},
prism: function(block,width,depth){},
prism0: function(block,width,depth){},
//
// create a cylinder - building begins radius blocks to the right and forward.
//
cylinder: function(block,radius,height){},
//
// create an empty cylinder
//
cylinder0: function(block,radius,height){},
// miscellaneous
// =============
// create a door - if a parameter is supplied an Iron door is created otherwise a wooden door is created.
door: function(b){},
// create double doors (left and right side)
door2: 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){},
// create trees.
oak: function(){},
spruce: function(){},
birch: function(){},
jungle: function(){},
//
// rand takes either an array (if each blockid is the same weight)
// or an object where each property is a blockid and the value is it's weight (an integer)
// e.g.
// rand([98,'98:1','98:2'],w,d,h) will place random blocks stone, mossy stone and cracked stone (each block has the same chance of being picked)
// rand({98: 5, '98:1': 3,'98:2': 2},w,d,h) will place random blocks stone has a 50% chance of being picked,
// mossy stone has a 30% chance and cracked stone has just a 20% chance of being picked.
//
rand: function(distribution,w,h,d){},
//
// places random flowers and long grass (similar to the effect of placing bonemeal on grass)
//
garden: function(w,d){},
// Copy & Paste
// ============
// copy an area so it can be pasted elsewhere. The name can be used for pasting the copied area elsewhere...
// drone.copy('somethingCool',10,5,10).right(12).paste('somethingCool');
// ... copies 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.
//
copy: function(name,w,h,d){},
paste: function(name){}
// Chaining
// ========
//
// All of the above methods return a Drone object, which means methods can be 'chained' together so instead of writing this...
//
// drone = new Drone();
// drone.fwd(3);
// drone.left(2);
// drone.box(2); // create a grass block
// drone.up();
// drone.box(2); // create another grass block
// drone.down();
//
// ...you could simply write ...
//
// var drone = new Drone().fwd(3).left(2).box(2).up().box(2).down();
//
// The Drone object uses a Fluent Interface ( http://en.wikipedia.org/wiki/Fluent_interface )
// to make ScriptCraft scripts more concise and easier to write and read.
// Minecraft's in-game command prompt is limited to about 80 characters so chaining drone commands together
// means more can be done before hitting the command prompt limit. For complex building you should save your
// commands in a new script file and load it using /js load()
//
// Properties
// ==========
//
// x - The Drone's position along the west-east axis (x increases as you move east)
// y - The Drone's position along the vertical axis (y increses as you move up)
// z - The Drone's position along the north-south axis (z increases as you move south)
// dir - The Drone's direction 0 is east, 1 is south , 2 is west and 3 is north.
};
//
// Implementation
// ==============
//
// There is no need to read any further unless you want to understand how the Drone object works.
