Step One: Watch Mary Rose Cook Live Codes Space Invaders from Front-Trends. (The second worst conference name ever?)
Step Two: Fork this gist.
Step Three: Respond to this question in your fork: What is one approach you can take from this Mary's code and implement in your project?
- Mimic her
tick()
function to get the gates to pass at a set interval - Using
.prototype
to set aspects of an element - Creating an
isDown
method to see if the user is pressing the left or right arrow buttons - Use her collision method to see when the ball is hitting a gate
Step Four: Totally Optional: take a look at some of the other forks and comment if the spirit moves you.
