Answer 1

Ok i got my red ball but when i click jump nothing happens is there something wrong?

Answer 2

You need to re-draw the circle...

Is it from the Game Development course? It is a pro project and I cannot access it but I assume they give an example for how to make the ball jump

Answer 3

I think the gist is this:

When you click the button
* update count
* update circle position
* clear canvas
* draw circle on canvas (with new position)

Answer 4

Put all your code inside if window.onload, else it will try to get the canvas before the canvas tag is loaded (that's the error in line 14)

Answer 5

When we click the button, count is increased by 1. What do you should happen?

Answer 6

You never display or output it. You could put a console.log(count); in the onclick function

Answer 7

Yes, after increasing count

Answer 8

I mean:

btn.onclick = function() {
count += 1;
console.log(count);
}

Whenever you ick the button, count will be shown

Answer 9

The button function is already connected to the button element – you do this with the onclick in your js

Answer 10

And redraw a circle?

Answer 11

Yes, its suppose to increase by 1 but i dont see it

Answer 12

Where it says btn.onclick or where exactly?

Answer 13

Tbh i have no idea can you like show me

Answer 14

You have to connect the jump button in HTML to js

Answer 15

How do you do that?

Answer 16

Ok now whenever i press the button the cirxle dissapears and it doesnt jump i think i did it right?

Answer 17

Yes its the Game Development with JS

Answer 18

Answer 19
