1  Java Game APIs & Engines / Java 2D / Sprite Questions on: 2004-07-12 11:26:54
I am currently trying to design a multiplayer action game that will be similar to Adventure of Link on the NES. I am running into the problem of how the sprites should be implemented. I want the sprites to be able to be dynamically changed based upon what the character is wearing and wielding. Is there a simple way of doing this or do I have to create an image of all possible results ahead of time?

I do not mean to be a total jerk but if you do not care for the status quo why don't you zip it up in the format and offer it up for everyone. As for tutorials and demos, there are plenty if you look. Again, if you want to contribute then do it but do not just whine about it to other people.

Afterall, open source projects are only as good as the community that works on them.

Is there any other possibilities? The file is in the same place as the model and it can see the model. I also double checked the path to make sure that there were no spelling errors.

5  Java Game APIs & Engines / Xith3D Forums / Md2 loader Question ---about Geometry on: 2004-03-22 17:11:52
There is a line of code:
  objRoot.addChild(new Shape3D(array, app));

Where app == Application and
          array == QuadArray


I understand that the Shape3D is being added to the scene graph but what is the QuadArray> and what does it do?

Any help is appreciated.
Thanks


Nevermind.... I think I understand. This is the platform that the figure is standing on. If I am wrong please correct me.
6  Java Game APIs & Engines / Xith3D Forums / Re: Moving Models Blues on: 2004-03-22 12:53:04
I am just curious if you have tested your getCenter method? I would suggest creating a sphere and import that as a model. Then move it around to see if it still has the problem.

This would allow you to see whether it is the moving method, or possibly the model. I hope this might help you.
What is the code that gets your center of each square?
7  Java Game APIs & Engines / Xith3D Forums / RenderPeer on: 2004-03-17 13:24:24
I am basing my code off the tutorial demo. I already have a gui previously designed that I want to attach a canvas3D to. How do I do this when the RenderPeer needs actual  measurements to create the CanvasPeer?
8  Java Game APIs & Engines / Java 3D / Re: Help , i'm a beginner on: 2004-03-12 16:59:20
JAVA 3d is an api that allows for the creation of 3D worlds. It is really just another extension of Java that Sun put out. You can use it to create games, even though it was not designed explicitly for games. It would probably be better to use something else. I have made small programs using Java 3D and the performance for my program was horrible.  Granted that it could have been my fault and not the actual API.

The best way to learn is to plug and chug. Look at people's examples to see how they work. Java 3D has plenty of books but I would recommend the one from Sun. If you can find it.
Read the Forums!! Forums are the best place to start to understand stuff. Questions you might have could might already be answered and have som snippets of code to explain further. Happy coding.
9  Java Game APIs & Engines / Xith3D Forums / Re: Lights...I am in the dark on: 2004-03-12 15:24:18
What would be the effect of allowing multiple models in a program to have their own light? Would this be too much of an overload for something like 10-12 objects?
10  Java Game APIs & Engines / Xith3D Forums / Re: MD2 Loader....the models on: 2004-03-11 13:41:42
Thanks for the info..... I think I am probably going to end up getting Character FX. I might actually pick up Milkshape as well. I have been using both the last few days and they are pretty good programs. Do you know what would be a good way of generating terrain?
11  Java Game APIs & Engines / Xith3D Forums / Re: MD2 Loader....the models on: 2004-03-11 11:35:28
I was more curious on the specific program. I tried opening up marvin in milkshape. It loads up without a problem but I cannot get the animation to actually occur. Off to another site to see if there are answers.
12  Java Game APIs & Engines / Xith3D Forums / Re: MD2 Loader....the models on: 2004-03-11 11:17:13
The program I am writing is turn based. I do not think that even a few hundred would be that big of a deal. Only one is moving at any one time. We shall see though. Assuming a hundred people care to play, which I doubt.
I have one more question.... what program did you use to create the md2 files?
13  Java Game APIs & Engines / Xith3D Forums / MD2 Loader....the models on: 2004-03-10 18:11:19
After running the MD2 Loader test file, which was pretty cool, I am now left with a few questions.

The code that switches the animation uses a tag. Am I right in assuming that this is dependent on the creation of the model? That tags are arbitrary?

Also, is there a limit to the length of frames that can be used?

I thinik I understand but am hoping for some feedback.
14  Java Game APIs & Engines / Xith3D Forums / Re: DirectX 9.0 Xith3D on: 2004-03-10 15:27:35
I know I am new here but I think adding Dx9 support would not be wise.  It would not just take away development from the current API but it would also break the JAVA system. By supporting Dx 9, there would be a potential problem of things working in Dx9 but not in the current setup. This is why I got into JAVA in the first place. I hated C because everything changes from system to system.
15  Java Game APIs & Engines / Xith3D Forums / Documentation for Loaders and Xith3D on: 2004-03-09 17:49:02
Does anyone have a link for the documentation of the loaders that are downloadable from the Xith website?
I have looked through the md2 zip file and have seen nothing to explain how the loader. Am I missing something that explains it? Also, is there a place to download the HTML Javadocs of the Xith3D API in a zip or tar? I would like to not have to go online all the time while looking up things.
Thanks in advance.
16  Java Game APIs & Engines / Xith3D Forums / Re: Creating a Grid based System on: 2004-03-09 15:31:56
Sputter....

Actually, that is exactly what I am trying to do. The next question is how to implement the animation of the "people"? I have been looking up the obj and other file formats but am still looking for what would be the easiest way to get a sword to be swung.
17  Java Game APIs & Engines / Xith3D Forums / Creating a Grid based System on: 2004-03-09 12:16:27
I am trying to convert a 2D game that was a software engineering project at my university. It is a turn based combat game that I now want to try to convert to have a 3D look. I would appreciate any advice on how to get the grid system up and running. I have been reading the Xith help files but am a little short on ideas on how to implement the design. Thanks.
18  Java Game APIs & Engines / Xith3D Forums / Re: Libraries--Help!! on: 2004-03-09 12:13:25
Did you download all the necesary third party files? If you did, did you put them all in the same path as you did with the other libraries that you can see? This error means that the program is not seeing the appropriate library. Change the CLASSPATH, ways of doing it are posted a few posts down, to allow the program to see the jar file.
19  Java Game APIs & Engines / Xith3D Forums / Re: Libraries...!! Help!! on: 2004-03-08 13:37:18
I am guessing Windows?

You need to put the files where the JDK can find it not just the JRE. All you really need to do is set the CLASSPATH to include the directory that you want to add all the files to. If you are running any other OS it should be the same thing. This should work for the libraries. For the models, I am going to guess that you should put those either in a place that your program can see or the directory which is the home for the program.
I hope this helps

THanks for all the help. I understand my faulty logic now.
21  Java Game APIs & Engines / Xith3D Forums / Re: Question using MacOS X on: 2004-03-05 18:05:58
Just thought I would add this error message:

No Fragment Program support, Skipping

Is this normal, and what is a fragment program?
22  Java Game APIs & Engines / Xith3D Forums / Question using MacOS X on: 2004-03-05 17:56:57
Is there any known issues with using macosX involving rotation. I just compiled and ran the HelloXith3D program but the cube does not rotate. Anyone know why? I hope this has not been answered already. I did a search before hand.
23  Java Game APIs & Engines / JOGL Development / Re: JOGL with Java 1.4.2 DP2 (OS X) on: 2004-01-07 17:31:08
After checking and rechecking I found the cause of the error was the wrong library was put into the directory. I hope this helps anyone else from such a stupid error.
24  Java Game APIs & Engines / JOGL Development / Re: JOGL with Java 1.4.2 DP2 (OS X) on: 2004-01-07 16:39:01
I also end up with the a similar error:

java.lang.UnsatisfiedLinkError: /Library/Java/Extensions/libjogl.jnilib


I have the two files only in the /Library/Java/Extension/
directory. Any ideas?
