Key events javascript

Question

Making a game and I wanna use key event press Ctrl key my player shoot a ball. I tried to use keydown and up but it makes him shoot more than one ball in one click.
Any suggestions

Answer 1

I'm not 100% sure but I gues keydown should work (if not, add array which will store key down in keydown event and swap on keyup

Answer 2

You can make array named for instance keys, than you can in keydown set keys[e.keyCode] to true and in key up false

Answer 3

I weren't doing this for long so I'm not really sure about key event properties name

Answer 4

Answer 5
