Hi,
I’m new to javascript so I’m not familiar with classes in javascript (I’m from Java). I declared a class like so:
class Obj {
constructor(name, distance, description, colour, size) {
//constructor
}
draw() {
//stuff
}
}
And then in the sketch’s draw method I attempt to call an Obj instance’s draw method:
function draw() {
object.draw();
}
But I get the error:
Uncaught TypeError: object.draw is not a function
What am I doing wrong here? Thanks for reading.
I can’t pinpoint anything wrong from your incomplete posted code. 
But you can check out these 2 sketches below that use class: 
My code is a bit long so I didn’t want to paste it, here is the link to my sketch
objects.push(new Object("Sun", 0, "description", color(255, 204, 0), 500));
Your class is called Obj, not Object, which is btW a JS builtin constructor:
objects.push(new Obj("Sun", 0, "description", color(255, 204, 0), 500));
You’re using for...in here: for (let object in objects) {
Use for...of instead: for (const object of objects) {
P.S.: It’s advisable to load assets within preload():
p5js.org/reference/#/p5/preload
-a-
objects.push(new Obj("Sun", 0, "description", color(255, 204, 0), 500));
not new Object()
-b-
for ( let i =0; i < objects.length; i++) objects[i].draw();
works well
