Squareheads

[EgonOlsen]

EgonOlsen: The game can not open/load a file in one of the jars. It might be a webstart issue, or I'm trying to load it in a way that is not working on your system. You could try deleting it from the webstart cache.

Yes, that worked! It runs @ around 500-700 fps now (framecounter is hard to read at that rate). That's on a P4HT@3.2Ghz, Radeon9700pro, WinXP. Collision detection seems to produce wrong results sometimes. I fall off the level twice.

[tom]

Another update. Here is a screenshot:

• Added collision detection against bezier patches. It's now possible to walk over the bridge without falling threw  
  
• Vertex colors is used on objects that do not have lightmap.
  
• Fixed a bug with regards to the fog.
  

Have not looked at the vertex array issues. And it is still possible to fall threw the map.

[tom]

Time for another update and to bump this thread back to the first page. Some of the things added this time:

1) Created a global matchmaker server. It's now theoreticaly possible to find someone to play with.

2) Remade the gui. It has got all the component types I'll need. It's also very easy to change and is perfect for prototyping. Still have to create a new look and feel for the final game.

3) Lots of sounds.

4) Doors

5) Ingame chat

...and of course lots of other minor changes.

Time for another update and to bump this thread back to the first page. Some of the things added this time:

Could you come up with a short description (approx 100 words) for me to put on the java games pages?

[pokkelipoo]

Very nice game. Reminds me a lot of Quake 3. Is there anyway to run in fullscreen? I'd also suggest adding an invert mouse option.

[tom]

New version is up.

I've added invert mouse option, fullscreen and md3 characters.

Spent most of my time rewriting the renderer. It's now 2-3 times as fast

[nonnus29]

I'm curious how you're doing visibility determination; bsp tree or something else?

[tom]

I'm using the Quake 3 bsp level format. It's a leafy bsp with a possible visible set. For each leaf there is a list of wich other leafs that are visible.

[coolepe]

I really like this projects. This proves that java is really ready for gaming.

I wanted to test your last version via webstart, but I got following error:

An error occurred while launching/running the application.

Title: Squareheads Test
Vendor: Tom-Robert Bryntesen
Category: Launch File Error

Could not find main-class sh.SquareHeads in http://home.halden.net/tombr/squareheads/sh_code.zip

[tom]

Could not find main-class sh.SquareHeads in http://home.halden.net/tombr/squareheads/sh_code.zip

I did some refactoring and renamed SqaureHeads to Squareheads. But the jnlp file gets cached somewhere and webstart don't see that the main-class has changed.  I've changed it back again, and I hope it will work now.

If anyone has problem starting the game: Delete it from the webstart cache and try again. That usually does the trick

There is 1 more 'Failed to add ......' but the java console disappears before I get a chance to click copy.

Strange i've had it working before now....

I wonder if its a 1.5 thing (but I thought webstart dealt with all the version control stuff...)

:edit: btw this was off a fresh download - webstart cache was totally empty.

[princec]

You can only use glDrawRangeElements if you've first checked for OpenGL12. Otherwise you must check for EXT_draw_range_elements and use glDrawRangeElementsEXT.

And it's broken on ATI 128 powered laptops

[oNyx]

1.4.2_04/win98se/gf2mx/38.82 deto/128mb/k7 500

It works and it's surprisingly fast 40-100fps

The fov is btw a bit low... around 70 or so instead of the default 90 (or more common 100-120).

[karatemarkel]

Nice work tom, runs really well on my comp (winXPpro Geforce4400Ti), the only problem is that it has a tendency to turn the gamma value up very high, making my desktop a bit too bright, and there was no one to shoot  , adding bots would be a good idea, and fun to code I imagine  

Good stuff though, if you are loading in the BSP or map format for your environments I'd love to make a map for the game. I've probably got a dozen or so half finished maps on a HD somewhere, and I'd love to finish them.

Ahh, q3 maps  

[tom]

Lots of response this time

There is 1 more 'Failed to add ......' but the java console disappears before I get a chance to click copy.

Don't know what went wrong here. Looks like your drivers is up to date. Maybe a native crash. Maybe I got a System.exit() hidden somewhere. I'll investigate.

java.lang.UnsatisfiedLinkError: nglDrawRangeElements

As cas mentioned, your card don't support opengl 1.2. Next time I will check opengl version needed, and possible rewrite parts to use extensions instead.

org.lwjgl.opengl.OpenGLException: Invalid operation (1282)
at org.lwjgl.opengl.Util.checkGLError(Unknown Source)
at org.lwjgl.opengl.Window.update(Unknown Source)

Another difficult one. Something caused an opengl error before the update call.

The fov is btw a bit low... around 70 or so instead of the default 90 (or more common 100-120).

Good observation. I set the fovy to 90 wich at a 4:3 aspect ratio would give a fovx of 67.5. In the next update I'll use fovx 90 deg.

the only problem is that it has a tendency to turn the gamma value up very high, making my desktop a bit too bright

Yes the gamma is probably set too high. I've got plans to make it possible to change the gamma, brightness and contrast from the menu.

and there was no one to shoot  , adding bots would be a good idea, and fun to code I imagine  

And bloody difficult  I did some experimental pathfinding, but the ai's got stuck all the time, so I gave up. Hopefully the game will be popular enough when it's finished, that it will be possible to find someone to play with online.

Good stuff though, if you are loading in the BSP or map format for your environments I'd love to make a map for the game. I've probably got a dozen or so half finished maps on a HD somewhere, and I'd love to finish them.

That's terrific. I really need content so any contribution is welcome. Do you create your own textures or do you use the one from q3? In the finished game I can not use any content from q3. I've got a friend who is going to make a level with original textures. You could possible use his textures when he is finished.

[oNyx]

There are a bunch of texturesets made for q3. The evil lair sets are kinda popular and are generally high quality

I just tried it.   I'm running 1.4.2_04 on XP.  Works great in windowed mode but I get the following when I try to go into fullscreen.

[2late4u]

Another little problem!!
During my game session, without a reason, the game return to the menù screen. So I have to reJoin! ... what's the matter?!?!

[erikd]

Works fantastic on my laptop. I also get the same mouse error (java.lang.IllegalStateException: Mouse must be created before you can read events), but I get this error also when I just change the resolution.

I'm really amazed by the speed and smoothness of it all. I'm getting ~60-130 fps with a crap video card.

[karatemarkel]

That's terrific. I really need content so any contribution is welcome. Do you create your own textures or do you use the one from q3? In the finished game I can not use any content from q3. I've got a friend who is going to make a level with original textures. You could possible use his textures when he is finished.

Sure, if you want me to use your own textures that's not a problem, I'm rubbish at creating my own textures anyway and would have probably used some of the evil lair textures, as oNyx mentioned, they are pretty cool.

Just send me a message with a link to the textures when they're ready and any other relevant information, I doubt I'll have time to make a huge map but I should be able to knock something up.  Been a long time since I last made a map and it'll be a nice distraction from trundling through the red book

It works on my Ti4200 on WinXP Pro (and it works pretty great too, getting up to >500fps)
Maybe it's a driver issue. You could update your driver, but whatever you do, *DON'T* use the latest; they (56.72) totally screwed my PC. NVidia and their damn drivers...
(I rolled back to 53.03 which seems stable, if not trouble free).

[tom]

A new version is up with a fix for the DrawRangeElements bug, and the window resizing bug.

[20thCenturyBoy]

Erikd - I'll try Tom's new version before updating my drivers.

Tom - just tried the latest version, unfortunately still not working for me. In my webstart log I get:
