Answer 1

Nice!
All you need is a `ctx.clearRect(0, 0, w, h)` over the whole screen before you draw the ball. Either in your draw function but inside the start function is probably a better place.

Answer 2

Thank you Schindlabua this is what i want... 👍👍
Did you think my code is ( good practice ) ? This will help me, because i can rewrite the same canvas in different way.

Answer 3

Yep looks pretty good!
I would make it so the draw function takes the ctx as an argument so the Ball doesn't have to rely on global variables. But that's a really minor thing.

Thanks my dear 👍.Schindlabua
