256 Pointsplateforms.create
how can l change one of the platforms to a be different type. Modify the platforms.create command on line 25 to use the string 'platform2' instead of 'platform'.?
let game;
let player;
let platforms;
let badges;
let coins;
let cursors;
let jumpButton;
let text;
let winningMessage;
let won = false;
let currentScore = 0;
const winningScore = 100;
function createCoins() {
coins = game.add.physicsGroup();
coinCreate(375, 100, 'coin');
}
function createPlatforms() {
platforms = game.add.physicsGroup();
platforms.create(300, 200, 'platform');
platforms.create(400, 450, 'platform');
platforms.create(100, 450, 'platform');
platforms.setAll('body.immovable', true);
}
function createBadge() {
badges = game.add.physicsGroup();
const badge = badges.create(550, 450, 'badge');
badge.animations.add('spin');
badge.animations.play('spin', 10, true);
}
function coinCreate(left, top, coinImage) {
const coin = coins.create(left, top, coinImage);
coin.animations.add('spin');
coin.animations.play('spin', 10, true);
}
function collectHandler(player, coin) {
coin.kill();
currentScore = currentScore + 10;
if (currentScore === winningScore) {
createBadge();
}
}
function collectBadgeHandler(player, badge) {
badge.kill();

231,236 PointsThe type of item created is determined by the string passed as the 3rd argument. Assuming you use one of the valid type names (and the instructions tell you which one to use), changing that string will change what gets created.
I'll bet you can get it now without an explicit code spoiler.

65,469 PointsLine 25 is this line:
platforms.create(400, 450, 'platform');
platforms.create
takes in two arguments (extra information provided to platforms.create
: the coordinate (the first two arguments), and the platform type. The challenge wants you to change the platform type from "platform"
to "platform2"
, so you just modify the line as follows:
platforms.create(400, 450, 'platform2');
I hope this helps! ~Alex
