Looks good to me, will merge around this time tomorrow if the other maintainers don't mention anything :)

well, it'd be nice to get a response from @hughbarney about that change to how asteroids are drawn - I feel like as there are generally quite a few of them it could make the game quite a lot slower - and the change to transformVertices would be pretty easy

[bobrippling]

Ah gotya - the poly drawing replacing the circles for example?

[gfwilliams]

Yes - poly draw itself should be ok, but I imagine constructing the polygon each time for every asteroid might slow things down

[hughbarney]

Yes it does make the game a bit slower. It is a lot nicer to look at.

I am afraid I dont know what 'and the change to transformVertices would be pretty easy' would mean in practice.

    g.drawPoly([
      a.x           , a.y - 1.5 * a.rad,
      a.x + a.rad   , a.y              ,
      a.x + a.rad/2 , a.y              ,
      a.x + a.rad/2 , a.y + a.rad/2    ,
      a.x           , a.y + a.rad      ,
      a.x - a.rad   , a.y              ,
      a.x - a.rad   , a.y - a.rad
    ],true);

I guess the suggestion is that there might be a more efficient way of calculating the points.
But I'm afraid my knoweldge of graphics tricks or manipulating shapes does not run much further.

Just done it - I made the asteroids rotate too

The only issue with this is playing it, I've found there are clear times when the bullet now passes right through an astroid, because at times it's drawn at 1.5x the actual radius

Thank you Gordon. It looks very nice. Sorry I did not know about g.transformVertices(), did not realise you meant using a built in function. I wondered if some sort of collision detection function could be added, eg g.polygonsOveralp(p1,p2).
