I was working through some Pygame tutorials last week and thought it’d be fun to see if Canvas/JS was fast enough in Fx3 to do some simple games.

So, I spent a couple evenings last weekend and made a really dumb Sprite class, and stole some reasonable “breakout physics” from this tutorial to make this Breakout clone in JS.

The collision detection for the bricks is a little sloppy (there’s a little damage on bricks from time to time) and I haven’t done any perf work yet, but it seems to work ok  in Fx3 nightlies on my MBP. Safari works ok too, just not quite as fast.

Any activity in other tabs seems to have a huge impact on performance, there’s probably a better way to do the sprite maneuvers etc. but I only had a few hours to spend on this so far. Pointers welcome

As previously announced on Tinderbox and planet, we’re migrating nightly production to running on the same machines as release production.

On the moz1.8 branch, we’ve been running the new nightlies in parallel with the “traditional” nightlies since Feb 15 2008, and are going to switchover live tomorrow.

The new machines:
* production-pacifica-vm
* production-prometheus-vm
* bm-xserve05

The old machines:
* pacifica-vm
* prometheus-vm
* bm-xserve02

Starting tomorrow, the performance machines will begin following the new machines. The new machines will publish updates and nightly builds to the usual location, and the old machines will be disabled (but kept around for a while, just in case).

If there is a reason that we should not proceed, or if you see any problems after the migration, please update bug 417147 or email build@mozilla.org.

Thanks!
Rob
