Java Forum / General / August 2007Asteroids game
I've been bored because work has been so slow. So I wrote an Asteroids game. It is far from done but it is pretty playable, at least on my desktop. http://www.knutejohnson.com/test Directions: Turn the ship with the arrow keys Accelerate the ship with the up arrow key Fire with the space bar If it runs out of fuel it cannot be maneuvered but can shoot until it runs out of bullets To restart the game click the mouse on the screen You can download the Asteroids.jar file and it will run as an application. I would appreciate some feedback as to playability and any deficiencies that you see in the game. If you have a slower machine (less than a Ghz), try downloading the Asteroids.jar file and resizing the frame to see if that makes it any better. It does require version 6.

The downloadable jar is in http://www.knutejohnson.com/test/jar There appear to be some issues preventing it from running on linux.

I was so disheartened I could not bother retyping it at the time. >..as to playability .. Quite useable at default size on this (aging) 1.8 Athlon. Unfortunately this particular PC is quite damaged, and shuts down on intensive CPU activity, so I suspect my leaving the game running in the BG actually contributed to the crash that took out my reply! Such is life.. I cannot run AudioTrace, a full-screen gradient paint with a 50ms refresh, or do any serious video editing, without the machine crashing and dying. One nice thing for usability would be to also add a keyboard shortcut for 'new game'. I keep forgeting to remove the mouse pointer from the play area - and then trying to shoot it.. (muses) Maybe that last paragraph went 'one sentence too long'. >...and any deficiencies .. Umm.. pretty much only the same ones that existed in the original game, as far as I recall it. I am much less a fan of asteroids than you, apparently. ;-) And yes, I understand that you are trying for 'authentic look and feel' so the entire idea of throwing in some (more) colors and adding a nice gradient background would probably not be the way you want to take it.

I had a similar problem with my old laptop. Turns out it was caused by dust clogging up the cooling fan and the air intakes (which Toshiba cunningly placed on the bottom of the machine). The machine turned itself off whenever it over-heated. Turning the machine off and blowing all of the dust out of the intakes and the fan fixed the problem (that was a couple of years ago and the machine still works fine now). Dan.

Spot on, thanks. All working smoothly now. (And you should have seen the dust!)

That's a good idea. I'll upload a new version here shortly that will reset with the <ENTER> key. > (muses) Maybe that last paragraph went 'one > sentence too long'.

(But personally, I think it > improve the game immensely.) I did want it to be as much like the original as possible. I don't remember if the original had any stars in the background or not. Also I think the ship might have been a little smaller in relation to the screen size. >> ..that you see in the game.

I have to go through it and check the docs but I'm pretty sure there are some 1.5 Graphics2D features in it.

I would have liked to try it on my 167 MHz Ultra 1, but unfortunately the latest Java available is 1.4.1... /gordon -- > I would have liked to try it on my 167 MHz Ultra 1, but unfortunately > the latest Java available is 1.4.1...

SignatureLew >> I would have liked to try it on my 167 MHz Ultra 1, but unfortunately >> the latest Java available is 1.4.1... > > Have you tried downloading a later version? I'm not aware of anything later than Blackdown 1.4.1 that runs on Linux on UltraSparc. There is a 4 year old release candidate of 1.4.2, but IIRC it isn't entirely stable on this platform. And the Blackdown project seems to have died; the most recent news item is from November 2005. /gordon -- >>> I would have liked to try it on my 167 MHz Ultra 1, but unfortunately >>> the latest Java available is 1.4.1...

Oh, that's what the "Ultra" means in the product name. I wasn't familiar with it, so didn't realize you were talking SPARC.

If I can make it work > with 1.4, I will. 167 MHz is extremely slow, but it helps me appreciate my modern machine at work (which is 20x faster). I wouldn't expect much game performance from it. On the other hand, original Asteroids ran on a 2(?) MHz 6502... /gordon -- On Aug 26, 8:00 pm, Knute Johnson <nos...@rabbitbrush.frazmtn.com> wrote: > I've been bored because work has been so slow. So I wrote an Asteroids I'm running WinXP Pro latest updates. On a Athlon 2200 1GB machine I'm a Java rookie or what ever comes before a rookie. I think I'm running Java 6.xx the latest. The game runs quite well. I'm not a gamer but played asteroids in it's heyday. When I quit the game I'm still getting audio bursts every 2-3 seconds.

Thanks for trying it. If you have a chance, please try the application instead of the applet. The app is at; http://www.knutejohnson.com/test/jar/Asteroids.jar You can resize the app to maybe make it perform better. The sounds should play when the space bar is pressed and when a rock is hit. Missed sounds that burp later is a sign of not enough processor. Thanks, SignatureKnute Johnson email s/nospam/knute/ Free MagazinesGet these publications absolutely FREE for up to 12 months.
