Micro:bit Commando Jump Using MakeCode
Programming with MakeCode
Conclusion and Listing


There are plenty of opportunities for improving the game - put the play code inside another loop so that the player can have multiple goes, add some sound, add a scoring system that take time into account, and so on.

All of these improvements are possible, but without subroutines or functions the size of the block program gets bigger and bigger and eventually so big it is unwieldy. 

What does this game implementation tell us about the MakeCode Block Editor? The verdict has to be that it is really only suitable for smallish programs. The problem is that the code that it produces is Microsoft's TypeScript, which isn't quite JavaScript and clearly has a Microsoft bias. There is also the problem that the code isn't the simplest you can imagine for presenting to a beginner. Comparing it with microPython you have to admit that it might not be much harder to introduce the beginner to this Python dialect. It is surprising that, after so much time, we are still presenting teaching languages to complete beginners that are not easy to use.

The Listing

Rather than give a complete block form of the program, it seems more useful to give the JavaScript version. If you want to you can copy and paste this into the JavaScript editor and switch to block view to see a complete block representation.

The complete program is:

let run = false
let t = 0
let man: game.LedSprite = null
let wall: game.LedSprite = null
let press = 0
let index = 0
function startGame() {
function countDown() {
    for (let index2 = 0; index2 <= 4; index2++) {
        basic.showNumber(5 - index2)
    basic.showString(" ")
function drawPlayArea() {
    for (let index3 = 0; index3 <= 4; index3++) {
        wall = game.createSprite(2, index3 + 1)
function playGame() {
    press = 0
    man = game.createSprite(4, 4)
    t = input.runningTime()
    run = true
    while (input.runningTime() - t < 20000 && run) {
        if (man.get(LedSpriteProperty.Y) == 0) {
            run = false
function moveMan() {
    if (press > 20) {
        man.change(LedSpriteProperty.Y, -1)
        press = 0
function endGame() {
    if (!(run)) {
function moveHorizontal() {
    for (let index = 0; index <= 4; index++) {
        man.change(LedSpriteProperty.X, -1)
function moveVertical() {
    for (let index = 0; index <= 4; index++) {
        man.change(LedSpriteProperty.Y, 1)
input.onButtonPressed(Button.A, () => {
    press += 1
