Gems - Lwjgl test game

WIP games, tools & toy projects Archived Projects
#1

Since the 48-hour game programming contest looms near, its time to publically test some of my base code i’ll be using, which has quietly been adding to my test game Gems. Version, oo, lets say π / 4 :slight_smile:
http://studenti.lboro.ac.uk/~cojc5/Programs/Gems03_11_2002.zip

Mainly I’m interested in how reliable this is on various systems, since i’ve only tested it on a few myself. A few notes:
[] Everything should be nice and self contained, simply unzip and run the .jar
[] Sorce is in the jar as well if anyones interested (although its pretty ugly in parts)
[] Please excuse my crappy text generator, i can’t draw characters :frowning: Plenty of work left to do on it…
[] The bug with ‘random’ crashes should be fixed (GC kicking in and collecting my FloatBuffer, while I was still using the pointer…)
[*] Stencil buffer may cause hedious framerates on certain configurations (windowed and/or 16bit colour mainly) but give it a try anyway please.

System specs, framerate (counter lower right of board) and any other comments very welcome.
Thanks

Haha - Nice

I get the FileNotFoundException too - but the camara controls work nicely…

I am using a Celeron 366@550 with a GeForce 2 MX
Uses ~ 40 % CPU and runs fluently, except for some small skips here and there - but don’t know what is causing it - might be my system…

Btw - I was running Windowed, since whenever I go to fullscreen in any Java 2 proggy my computer crashes (nv4_disp.dll) :frowning:

#4

uh - Not seing any FPS in windowed mode?

Nice to see some actual running programs using LWJGL!

#5

Thanks everyone for trying it, i’m going to be working on it quite a bit this week hopefully fixing bugs and tweeking stuff.

distort.ms3d can be safely ignored, the mesh isnt used anywhere anymore, looks like I just forgot to take out the loading code :-[

FPS - I have no idea why its not displaying in windowed mode, does it display in fullscreen mode? Other than the initial setup, the rendering is all identical so it shouldnt make a difference… Failing that, www.fraps.com will work as a temporary fix :-/

Is anyone seeing the seems in the skybox? It seems that GL.CLAMP_TO_EDGE is missing from lwjgl ??? so I had to do a quick texture coord hack to try and make up for that

#6

I’m running a P4@1.3Ghz with 640 meg ram and a 128Meg Gforce4.

The frame rate is always maxed out in all resolutions to match the refresh rate.

The CPU usage seems to hover around 20% except in very high resolutions where it bounces up and down a lot but never gets above 22%.

Didn’t notice any seams however the texture on the axis is only visible from one side.

#7

Hello!

I can’t get it to work, but since I know jack shti (deliberate Jeff-like mispel) about OpenGL etc I’m probably doing something wrong… I get the same error with full screen on/off, different resolutions etc. My config:

XP, PIII@933MHz
Matrox G400
JDK 1.4.1_01

And (tataaa!), the actual error:

aha, I was stumpted with this one for a while on one machine - apparently a bug in Lwjgl that should be fixed in the next version (any news on that anyone?). Unfortunatly nothing you can do until then though :-/

#9

Same error for me, cannot get it to work.

#10

Unofficial bug fix release attached for those that need it :slight_smile:
No instructions or warranty… just built it from my local source code.

#11

Cheers Cas, any word on CLAMP_TO_EDGE appearing any time soon?

#12

Oh, I didn’t know it wasn’t in there! I’ll take a look at adding it.

It’s been implemented dodgily by a few vendors. Might be best not to rely on it.

Cas :slight_smile:

#13

Odd, Real Time Rendering seems to suggest that GL.CLAMP has been implemented to varying degrees of sucess, and that _TO_EDGE should generally be used instead - either way, CLAMP definatly doesnt do what it says on the tin on my Geforce2 :o (despite nVidia usually being pretty compliant with their drivers…)

#14

By the time you read this, i’ll have uploaded an updated version (kicks modem) with Cas’ bug fix in it. Text is still not perfect, but much less retina-burning than before :slight_smile:

#15

It froze my PC right after saying that it couldn’t get ahold of the keyboard :-/

Win2k, Athalon XP 1600+, TNT2 Vanta

#16

Hm, that hasn’t manifested itself for over a year. I wonder if it’s a DX issue.

I found that simply clicking the mouse did the trick.

Cas :slight_smile:

Still getting an error with the “latest” version - different one now, though:

#18

I bet that you’ve somehow got a mode that your graphics card doesn’t support in hardware, been punted back to Microsoft’s software renderer, and Orangy hasn’t checked to see if he’s got the WGL_swap_interval extension before he goes calling it. My guess, anyway :slight_smile:

Cas :slight_smile:

#19

I get the same error no matter what mode I try… (with or without fullscreen - I even tried no fullscreen, the exact same mode that I currently have) - no disco…

Just a note, though: I’m not whining and complaining in earnest here, I just figure you actually like to know that it isn’t working :wink:

/M

#20

Oops, Cas’ has hit the nail right on the head there, I hadn’t realised i’d need to check that was present before calling it :-[ I’ll see if i can figure out how to fix that tonight (and the weekend competition looms ever closer - time to stock up on the Red Bull…)
