User-Defined Functions

Build a Brick Block

In this chapter, we have a function already defined for us: put_brick(point). Your job is to learn how to call this function and use it to build brick blocks.

Make sure the code editor has the following code:

// Lesson 2: Function put_brick(point)
// CodeCraft Setup
let game = new Game();
let materials = game.materials;
console.log(materials);

// A black block for your reference:
let p = new Position(0, 1, -20);
game.setBlock(p, 1);

// Define function put_brick, point is a Position object:
function put_brick(point) {
  game.setBlock(point, 17);
}

// Call put_brick to build a brick block:

This function put_brick has one input parameter point which is a Position object.

To call put_brick(point), we need to create a Position(x, y, z) object indicating a point in CodeCraft world. Now add the following code to a new line at the end:

let s = new Position(1, 2, -20);

then call put_brick with s as input value:

put_brick(s);

Run the program and enter the CodeCraft world to see a brick block at x=1, y=2, z=-20

Next create two more Position objects, t, r and call put_brick on them:

let t = new Position(5, 5, -18);
let r = new Position(-2, 4, -19);

// call put_brick() on t, r

put_brick(t);
put_brick(r);

See the picture, you should have the same result in the CodeCraft world.
