Hi guys,
I’m struggling to understand the bouncing balls assessment. I don’t understand what I need to do in response to the passage below.
Also, my balls have shrunk and I don’t know why (not something I thought I’d write in this forum).
I’ve provided a link to my code below, any help would be much appreciated.
Regards,
Jared
Hi @Jared_Cave!
This is a really difficult assessment, and looking at your code, you are definitely getting there.
The first thing I did was to comment out the line firstCircle.setControls();, as the console was complaining that setControls is not a function. So there must be something wrong with your EvilCircle constructor.
You should also move the creation of the EvilCircle instance out of the loop - you don’t want one EvilCircle for every ball created.
Also, I’m sorry to see that your balls have shrunk. I was going to suggest some ointment, but instead I investigated your code. if you run balls[0].size, it returns true, whereas it should return a number. I wonder how that has happened?
Have another look, and see if you can figure this out. Also, feel free to have a peep at our version, if you want to get some more clues: https://github.com/mdn/learning-area/blob/master/javascript/oojs/assessment/main.js
Hi Chris,
Thanks for the pointers. I realised I skipped the JSON assessment by mistake so I’m going to complete that first then come back to this tomorrow/Saturday. I’ll let you know how is goes.
Regards,
Jared
