Squareheads

[tom]

Squareheads is a first person shooter, that I'm working on in my spare time. It's going to be multiplayer only game. Although I might try to make some boots.

A webstart demo can be found here:
http://home.halden.net/tombr/squareheads/squareheads.html

[kevglass]

Ok, its a little basic atm, but I think its pretty ace! No hassle, no problems.. just worked...

Keep it up!

[erikd]

Cool stuff  
I'm looking forward to seeing this progress!

Worked perfectly, Love the avatar!

[Seekely]

no problems, nice start

[EgonOlsen]

Doesn't work for me. The window opens, everything is black and then it closes. That's on a P4@3.2Ghz, Radeon9700pro (Catalyst 3.9 drivers), WinXP home SP1, Java 1.4.2

Edit: Deleted the JWS caches and tried it again and now it works fine.

[markush]

Works great!

WinXP Pro, java 1.4.dontknow:), radeon 9700pro, athlon xp 2200, 1.5G Ram

[swpalmer]

Does not work on Mac OS X (1.4.2DP1)

The application silently disappears when launched - no logs.
I suspect there is an exception thrown that is being caught without actually doing anything to handle the error.  tsk... tsk...

[tom]

Thank you all for testing the game!!

For those of you who did not get it to run. Please try again. I've added an error dialog that is shown if it crashes. If it shows (fingers crossed), please post the error message here.

Hi,

runs GREAT!!!

I'm looking forward to see the full game.

swpalmer:
Looks like I made a copy and past mistake in the signing script. The windows dll was used instead of the osx jnilib  

I've corrected it now, if you wan't to have another go. I think the game will work on a mac. Although, wasn't there a problem with buffered keyboard input when using lwjgl on a mac?

[Markus_Persson]

Woo, works very well. =D

Kinda hard to actually get a kill in it though. =)

[swpalmer]

Ok launches now on Mac  (had to delete the app and re-install since WebStart did not pick up an updated JAR)

Problems:

- No mouse cursor..  I had to watch for the hover highlighting to know when i was over a button.

- Only uses built-in track pad of my powerbook, I have a USB mouse connected (impossible to play this style with a trackpad).  AlienFlux does work with the external mouse so this shouldn't be a limitation of LWJGL.

- Couldn't move, so I assume what you were saying about keyboard support on Mac in LWJGL might be true... I will have to fire up Alien Flux again to confirm that.. i assumed it was fixed though since AF announced the Mac release.

[tom]

I use the hardware mouse cursor in lwjgl. But I did implement this very quickly. So I don't rescale the mouse cursor if it do not match the supported min/max size. So probably the cursor size on mac is not 32x32 and it fails. I do print it out though. So you could check it out, if you look at the java console. I'm going to fix this...eventally  

Either that or hardware mouse cursor is not supported.

I don't do anything special with the mouse except using the hardware cursor. Don't know why it does not use your mouse.

w,a,s and d uses polling, so that should work. I only use buffered input on [space] and [esc].

Btw. I use lwjgl 8.0 that I downloaded a month ago. So there might be some fixes in cvs that I don't have.

[swpalmer]

W,A,S,D  did not work.
*edit* I didn't see any print out about the cursor.. but that may be an issue with my Web Start client.

[tom]

A new version is out with the following changes:
-ai players
-jumps
-frag limit

[MickeyB]

very nice!!!  Makes my CubeWars look sad.  

Keep it up!

[tom]

To save time I've decided to use the q3bsp as the level file format. I've started on the viewer, but there will be some time before I can release a demo of it. But until then I've made some screenshots you can look at:
http://home.halden.net/tombr/q3/screenshots.html

Q3 shaders are for the most part implemented. This allows for effects like environment mapping, texture coord animation, vertex animation, misc blending etc.

I've not implemented fog nor collision detection agains bezier patches. Don't know if I'll bother putting it in.

The renderer is not optimized. I don't use multitextureing, and I only use glVertex3f, glTexCoord etc. The only optimization I've done is to minimise texture binds. Quake is more than 4 times as fast as my viewer   Will be difficult to get close to that.

[Conzar]

Works fine in Redhat 9.0

[kul_th_las]

I finally got it to work. The game of ultimate death to textured rectangles! Whoohoo!

Keep it up.

[blahblahblahh]

Either that or hardware mouse cursor is not supported.

Geforce2 and I get "hardware mouse cursor not supported" and it does several annoying things as a result.

1. you have to alt-tab to get your mouse cursor back in x-windows. Grr.
2. once you've got your mouse cursor back, the game comlpetely ignores the mouse.
3. If you drage the window around, the game kills the mouse cursor again, but now at least it will recognize the existence of the mouse (as per swp's comment, you have to navigate via highlighting).

[tom]

Sorry about that. In the next version I will provide a software cursor if the hardware cursor is not support. It will still remove the native cursor, but you will have a visible cursor so that you can press the exit button.

[tom]

I've updated the demo. I've replaced my wonderful home made box level with a quake 3 one. So check it out.

Some known issues:

• No collision detection against curved surfaces
  
• No collision detection against the transparent floor
  
• When walking into the teleporter you will instead sometimes walk on top of the teleport.
  
• Filtering on some lightmaps is sometimes turned off
  
• AI can't navigate in q3 level so they are useless.
  
• Sometimes dies without reason
  

It's now possible to fly by holden down space. This way it's more difficult to get stuck.

Enjoy!

It also makes everything brighter and leaves it that way.

Another issue (which is not really your fault), but I recently moved away from IE and I now just use Opera. Webstart doesn't seem to start automatically when it's not a jnlp file but a php file like yours.

cool, works fine here (xp, radeon 9700, jdk 1.5)
very nice speed, especially compared to the xith demo - though I don't know if they are comparable ?

[tom]

It also makes everything brighter and leaves it that way.

Yes, I modify the gamma settings to make things brighter. The problem is that it is not reset when the vm crashes. Maybe I'll provide another way of making things brighter. Atleast until it becomes more stable.

Webstart doesn't seem to start automatically when it's not a jnlp file but a php file like yours.

My ISP has not set the jnlp mime type. So it's either a php, or no webstart

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. Have you had any problems with webstart before. Ary you running window or linux? What browser?

The other two exceptions reported by zparticle and erikd are vertex array and/or vbo related. I'll have to read up on this. And defenitly add more error checking

very nice speed, especially compared to the xith demo - though I don't know if they are comparable ?

Well, using a scene graph to render a quake level is not the most efficent way of doing it So using xith will never come close to a purpose built engine. It's more interesting to compare it to the original q3. Because of vbos it's possible to make a quake viewer that is faster the the original. The special effects (fog, waving flags, animated textures etc) is slowing me down alot dough  As I haven't had the time/skill to optimize it.
