Getting to know the Canvas

Sign in to follow this  


I am familiarizing myself with JS and HTML5, Canvas first ... not WebGL yet.

The first thing I am trying to do is programming what I had in mind when I heard that there is a combination between Tetris and 2048.
Not sure if the game mechanics will make a lick of sense, but I want to know what it feels like.

Working Title: NPAA (Not Proc At All)

I have not managed to keep the code clean, so I will have to refactor soon.
I also need to look at articles about object oriented programming in JS.
What I have so far are procedures, procedures, global constants and variables and ... procedures ... and already the if/else statements annoy me.

So far I can cycle through the different block types and their rotations (with the arrow keys).
The delayed response to the user action is a feature, not a bug btw. tongue.png
In the actual gameplay the response will be immediate.

The next step will either be writing some ugly gameplay logic ... or researching and refactoring.

is that page that's linked to supposed to do something?

As soon as you click on the canvas the main program is running ... then the mentioned features should work:

oh yeah, JS OO is funky. Here's what I settled on: http://tnovelli.net/ref/js.html#oop


I actually think that is good stuff ... finally I can create two blocks :-)

Probably hard to figure out, though ...


Moving on to gameplay ... and maybe some more refactoring.
