1  Game Development / Performance Tuning / Re: Mac OS X or Intel GMA problem? on: 2008-11-02 01:36:05
It might depend on what you do too, and what you use.

Java2d can be terribly slow on some things, like transparancy, if that is what you using.

I have a GMA950 in my machine at its run fine for all simple things.

I dont like any of them, sorry. I dont feel that they say anything, they feel like random combinitions of mystic sounding words. No character in them.

Isnt it better to use something from within your gameworld, name of the country its in or anything?
3  Game Development / Newbie & Debugging Questions / Re: Game is freezing and not working properly on: 2008-09-14 19:57:37
fletchergames, wouldnt it be a good idea to encapsulate the timing things in some sort of timer class. As it is now a lot of local variables are floating around and its not very obious what they are doing, espacially if you what to do more things in the mail loop. And a timer class would be easier to reuse too.

Don't kill your little darling, just slap her around a little  Smiley

You are immensely atrocious, I am shocked. (Smiley)

Yeah, I think you have some good ideas.

Just an idea, it might be cool to add some gameplay elements from Namco's classic Bosconian: blowing up space stations, spy ships that might alert the enemy of you presence, alert states. (If you don't know the game, try it out in MAME, it might give you some ideas).
That would be very cool, unfortunately I wont have the time anytime soon... Sad
5  Games Center / Archived Projects / Re: Air Attack (Renamed) on: 2008-09-14 18:06:02
Woah, I thought Id grown out of the age when you enjoy silly games wherer you shoot everything that moves. So wrong I was...

This is brilliat, wonderfully addictive, its on its way to ruin my university degree!

Cooles features: The particle stuff, how they bounce around, the napalm. That you can capture the ejected pilots, the shot down planes that stays there.

Most dangerous enemy: The green planes, they dont hit you very often but they destroy the land!

How it could be improved: Other weapons? Superwepon that destroys everything? The jumping is a bit awkward, a more realistic fall behavior would be nicer. Maybe more land, it irritating when its all blown away to fast. Maybe constant fireing rate in stead of one rocket at the time.

The graphics could be more polished of course, but that wouldnt make the game more fun, really. The particels could be a little transperent in stead of just squeres. The pictures could be nicer. Some animation when the player moves.

Fulllscreen didnt work, even for the downloaded jar file. (Ubuntu 8.04) Another window opens, when I click, but not in fullsceen.

Would be fun to have a look at the code!

/Jens - Nr 5 on the highscore

Jesja, StrafeFighter source code is now up on google code
Cool. Looking forward to looking into it.
7  Games Center / Showcase / Re: Callisto Carnival - Space thruster on: 2008-09-07 17:30:25
I would also make make all movement slower. Everything whizzes by so fast that as soon as something comes into view, it either leaves a fraction of a second later or I explode.
And, this isn't directly related to shooting enemies but if you reduced the gravity force then the game would be easier too.
Reduce the gravity? But the gravity is my nice, nice little darling, are you suggesting I should kill my little darling?

Hrm... I guess you right. That and lower thrust force maybe. And maybe I should introduce a maximum speed to slow things down, even if its not very physically correct.
8  Games Center / Showcase / Re: 2D Rally Game on: 2008-09-07 15:54:34
Strafe Fighter! Yeah! This is very cool! Is very similar to what I am doing, maybe a little smoother and more feature rich in the gui. I like very much the gui details, that youve included so many plantets, and the way the ship moves.

And I like very much this type of game, especially if youre going to add trade/explore elemtents. Clearly, despite what other people on this forum might have suggested to you in the past, this is the project you should develop.

On you website you mention releasing the source. If you do, I would be immensely intressted in having a look at what solutions you use comparing to mine.

And please have a look at my game, youll gonna recognize stuff! (just hope itll run on your system)

9  Games Center / Showcase / Re: Callisto Carnival - Space thruster on: 2008-09-03 13:33:59
Tried too. About the explosion bug, maybe it's not a bug and your ship is simply attracted by the gravity force of the red star?
My theory is that it hits the people that really deserve beeing blow to pieces a lot of times.

Is it really feasible to hit an enemy ship?
Well, you have to sneak up on them, follow them and shoot them a lot of times from a short distance. But you're right, its to hard. Any ideas about what could be done about it? Just make the ships bigger? I would'nt really like that...

Great graphics!
Thanks! The great thing about space is you dont have to do much to make it look good, a few stars and platets and it looks good. A nice particle engine flame and it looks really great.

It looks very promising though. Nice graphics, and all very smooth.
Thanks, but sometimes its not totally smooth. You can seen it on large objects like the planets and the sun, they kind of flicker a bit when you move fast past them, looks much like tearing but I dont know. Please have a look, and post suggestions about what this can be! (or is it just on my system?)

I run with Display.setVSyncEnabled( false ), switching this on made to problem much worse. I update the game state depending on the lwjgl timer. I dont drop any frames, but I dont draw very complicated stuff either.

Uploaded a version that asks if you want to run in fullscreen before it starts.

Its possible that this also affects the explosion bug, because it makes the game pause for a short while before it starts.

Please let me know if it does! Thanks for all the feedback!
11  Games Center / Showcase / Re: Callisto Carnival - Space thruster on: 2008-08-26 22:01:54
Yeah, we tried it over the internet, although not very much or for very long. But to do it in a larger scale I guess it wouldnt be sufficient. Feels a bit insane that it acctually worked for us.

Ive looked around a bit for tutorials about this kind of stuff but havnt found much usefull, does anyone know anything good witten about it? Design and different approaches to networking?
12  Games Center / Showcase / Re: Callisto Carnival - Space thruster on: 2008-08-26 20:44:40
That's very nice! I like the graphics. I was able to fly around and stuff and got shot down Grin

It would probably be nice to allow players to start in "window mode" if they choose so, rather than fullscreen. I don't quite like how you hijacked my screen without warning.
Sorry, Ill add a popup asking about it or something. But it looks so much nicer fullscreen!

Are you planning to make it multiplayer? Is it already?
The multiplayer mode is implemented, it has basiclly just been plugged out due to a rewrite of other code. It works in a funny way, the idea of one of my crazy but talented groupe mates. Every computer runs it own copy of the game, including ai players, the only things sent over the network are key presses and a "tick" event when its time to update the game engine. And it accually manages to stay in sync! All the machines run the game in exactlly the same way, regardless of floating point errors and everything else that could make them drift apart. Guess thats a credit to Java.

13  Games Center / Showcase / Re: Callisto Carnival - Space thruster on: 2008-08-26 20:30:43
Gameplay could do with some tuning, GFX looks really nice!
Thanks! Yeah, guess your right about the gameplay. Guess you all know the problem: You spend so much time playing your own game and get so good at it so you dont notice if its unplayable to others...
14  Games Center / Showcase / Re: Callisto Carnival - Space thruster on: 2008-08-25 19:08:06
If it helps, I get the same explosion problem if I do nothing while it is starting up, but, if I start pressing the up arrow while it is launching, I can play normally.  At random, I will get the explosion problem after I have been playing a bit.
Right, thats a good clue, unfortunately I dont have the time to look into it right now...  Sad

On a positive note, the graphics look really nice.  Good job.
15  Games Center / Showcase / Re: Callisto Carnival - Space thruster on: 2008-08-25 11:12:22
Im totally puzzled. It has run when I have tried it earlier and it run when I tried it today on xp pro ver 5.1 ser pack 2, java 1.6.0_05.

All the explosions are because, for some reason, you collide ( with yourself? ) immediately after spawning, then you respawn and collide again. And so do the ai players.
16  Games Center / Showcase / Re: Callisto Carnival - Space thruster on: 2008-08-25 09:36:41
Doesn't work on my machine:

This is catastrophe, no one able to run it?! What have I done when I tested this? Have no idea about this last one either, sorry.

But I successfully ran it from a xp machine in school today...
17  Games Center / Archived Projects / Re: Beetles - a game without a plot... on: 2008-08-24 21:49:49
I cant play, the window is filled black and nothing happends! Too bad, I liked the look of it, bit greyish, theres too many games out there that look terrible because they use too strong colors.
18  Games Center / Showcase / Re: Towerball on: 2008-08-24 21:25:15
I get 1fps, its a bit jerky. I suppose this it not the intention? (web start version)

Ubuntu 8.04,  intel GMA950,  java 1.6.0_06, intel code2duo T7200
19  Games Center / Showcase / Re: Callisto Carnival - Space thruster on: 2008-08-24 21:10:22
Allright, sorry, have to invertigate this more closely....
20  Games Center / Showcase / Re: Callisto Carnival - Space thruster on: 2008-08-24 20:56:49
This version thats up now I have seen run on vista machines, sometimes after a restart. Its very strange.
(re-clicking of the link, not restart of the computer)
21  Games Center / Showcase / Re: Callisto Carnival - Space thruster on: 2008-08-24 20:52:32
This is strange, the game gets into this state sometimes when it has been disturbed, when it continues after having stoped at a break point or a screen shot has been taken. I dont know why, have to dig into that sometime.

But it has run on several vista machines before, have you tried restarting it?
22  Games Center / Showcase / Callisto Carnival - Space thruster on: 2008-08-24 20:08:34
Thought it would be nice with some comments on this, think its pretty cool myself...!

This is space thruster, the fun part is the gravitation, you can enter in to an orbit around a planet and you have to struggle not to fall into the sun while combating the enemy.

Its reallly not much of a game yet, theres no points or lives or menus or anything, but maybe the next step should be to introduce some kind of goal, maybe a mission system.

Ive been a design freak the last couple of months so there has been put enormously amounts of time into moving things around to make everything as modular and clean as possible and applying as many design patters as possible, but parts of the code is still a bit confused.  And theres not much documentation. But any comments or suggestions about it is very highly appreciated!

Its lwjgl, with jogg and jorbis for the sound.

Stear with arrows, shoot with space, self destruct with k.

The game, Java Web Start: (5mb)

The source and resources in an Eclipse project: (4mb)

Battle around the New Constantinople space station (anyone played Wing Commander: Privateer?)

Ahh! Too close the sun, burning!

Orbiting the planet Earth,  on the way to dock with the Mir space station.

- Gravitation
- Laser and plasma ball guns
- AI player
- Dockable space stations
- Radar
- Sun burning when to close
- Sound
- Nice particle engine flames
- Animated explosions
- Modular and extendible design
- Netwok suppor nearly implemented...

This started as a  school project, credits to my wonderfull group mates, Tommy Carlsson, Simon Göransson, Björn Lindfors and Emil Pettersson.

Turned out to be gl drivers after all. It started working after an auto update.
24  Java Game APIs & Engines / OpenGL Development / Re: Black screen on: 2008-03-15 17:26:48
OpenGL-drivers seems to be up to date. And I can run other lwjgl things (SpaceInvader game from the same page).

It might have something to do with texture loading, but it says in the console that it loads textures.

Im getting sound from the application too! Very frustating!

25  Java Game APIs & Engines / OpenGL Development / Black screen on: 2008-03-15 16:04:27
Im trying to run Asteroids tutorial from, wich use LWJGL rendering

Ive finally got it to compile (f-ing h-ll, I thought I left "linking" problems behind when switching fom c++), the window opens but all I see is a black screen! The console says it has loaded some pictures and models. When I try to run it in with Web Start I get the same result.

Does anyone have any idea?

Im using: Vista, GMA 950 graphics card, Eclipse.
