Typing Game Version 2

Chris Bishop | 23 June, 2008 | 12:14
After finishing exams I am back  and have finished version 2 of the Typing Game.  I added vertical movement to the cubes.  As a side note, points are deducted for allowing cubes to fly off the screen. To determine if a cube was off the screen I had to manually populate the screen with a column of cubes to determine how many it would take until I was off the screen.  The value is hard coded in so if the dimensions of the canvas or the position of the camera were to change my cubes would disappear early or late. My demo works with the 0.2 release of the Canvas3D API and that is what it is using on this website.  I plan on upgrading my FireFox to the latest and greatest and see if all is well. My next goals are between fixing the 3d graph or adding radio buttons to the Typing Game that would allow someone to change the difficulty on the fly.  Demonstrating that the 3d canvas can interact with elements on the web page.

The game play feels better but the cubes seems to

The game play feels better but the cubes seems to have gotten slower… is this to combat the imploding/exploding cube bug?

I just tested your latest version with my mac again

I just tested your latest version with my mac again and its ALOT smoother. On my pc its extremely sluggish (everything is slower than the “easy” setting on the mac). Are you timing the animation based on time or some counter loop? On the mac, its very clean though. I’m wondering why this is… my pc’s video card is an atixtx 1900… its not the latest but its not too bad either. Is it the library code that is slow here? the way its animated? or is it due to canvas3d having to do some software emulation?… Not sure what the answer is but think we should look into this.

A spec change that keeps coming back to haunt me

At some point, the way firefox handles keyboard events changed. I’m not sure exactly when it happened, all I know is that it broke how I was dealing with keyboard interaction on almost every demo I’ve written (for example,the mocap demo and MotionView). When I wrote the demos, the keydown event would be fired once, [...]
