I’d like to point out that there are a few lines of code that need to be added to the Ship.as, GameSprite.as, and Asteroid.as classes that aren’t explained in this section of the tutorial and could be the cause of some of your errors. The solution can be found in the source code.

That being said, I have a suggestion for improving the performance of your keyboard routine. Instead of creating an array to track items that are pressed which requires searching linearly through the array each time a key is pressed, released, and checked, create a boolean array map of all the keycodes. This allows you to directly update each key individually and look it up in one step.
A quick search online found that the maximum keycode is 222, so if you do the following:

private static const MAX_KEYCODE:int = 222;
var key_states:Array;

public function Game(stageWidth:int, stageHeight:int)
{
key_states = new Array(MAX_KEYCODE);
for (var i:int = 0; i = 0 && e.keyCode = 0 && e.keyCode = 0 && keycode < MAX_KEYCODE)
return key_states[keycode];
else
return false;
}

Cheers, and thanks again!
Steve

switch(e.keyCode)
{
case Keyboard.LEFT:
{
TurnLeft = false;
break;
}
case Keyboard.RIGHT:
{
TurnRight = false;
break;
}
case Keyboard.UP:
{
MoveForward = false;
break;
}
case Keyboard.DOWN:
{
MoveBack = false;
break;
}
}

Before the patches is when I played, and they supposedly tilted the difficulty curve quite a bit. When I played you could only take on one guy at a time– two would chop you down like a block of wood, because it wouldn’t let you attack when you have been hit.

I like how they did the story– and don’t think they really need any gimmicks to make people “explore more”. I see it as more of bad game design when you can’t find where the heck you need to go. Skyrim and The Witcher both do a fairly good job of putting neat stuff in between goal points, so you usually have to stop and explore new things that pop up along the way, and sometimes get distracted doing stuff that is not part of the main quest because it is interesting.

I’ll have to play again with the ‘enhanced edition’, and see how it has changed/ been improved.

Thanks for the comment!

Great job, I’d like to see what games people have went on to create

Need to create some more tutorials soon– been too long, and I’d like to get a game development group going.

It’s best to ‘trace’ things out to see to make sure things are happening when they are supposed to.
I’d say when you add a bullet to the array have it trace(‘added bullet’);, when you update/render the bullet, trace out :trace(‘bullet updating’);

That is the best way to track down the problem– validate each thing. Even try not rendering the ship to see if the bullets are being rendered behind it, and just aren’t updating and moving across the screen.

Let me know!
