Full Stack JavaScript Techdegree Student 379 PointsWhy is the syntax for function addItems and function addPlatforms different when they are both doing the same thing?
[Contd.] Which is adding graphics to the game? (to add a coin, we are using createItem, and to add platform we are using platform.create) Is it because to add a coin we are using a different function as it is a collectable item which has to disappear when collected?

var item = items.create(left, top, image);
but also includes code to add the spin animation to coin
item.animations.add('spin');
item.animations.play('spin', 10, true);

54,971 PointsYes. It looks like animations are set individually and the function is used to avoid repeating three lines of code for each item. Whereas after creation the platforms use a setAll method to fix the position of all platforms.
For fun comment out the following and see what happens
platforms.setAll('body.immovable', true);

Full Stack JavaScript Techdegree Student 379 PointsOh so is that why we are using function createItems for coins, poison, and stars and just platform.create for creating platforms?
