Game Development / Performance Tuning / Seamless Terrain
|
on: 2007-03-01 00:04:42

Anyone want to comment on seamless terrain. Different then infinite terrain, but the way I was planning on doing it was to have a 3x3 grid around the player of terrains, and whenever he passes over one it'll unload the farthest ones and load in the height map and initilize everything for the new terrain... are there better ways?

Oh the Client I am still working on. Thanks for the comments guys! Im thinking about removing the Game class, as it serves no real purpose and instead using the vanMain class as the main class, would look something like: 1

Game Development / Newbie & Debugging Questions / Wondering effeciency of my code.
|

Okay so I'm new to alot of techniques in Java, such as OOP. My code is messy, execution of things are a bit wierd. Im wondering what way I could better organize my code so that it is easier to read and runs more effecient! Please any tips are welcome! (Paste is of my 2D tile engine) Sorry if there is a bit much. Just want to make sure I am on the right track, and not doing any bad habits.. 1

Java Game APIs & Engines / JOGL Development / Common Problem installing JOGL

on: 2005-06-06 02:31:48

Hello Fellow Java Users. I am trying to get into JOGL so I can create demos and basically play around with it. I am having a issue installing JOGL and running it. My Setup: Windows XP, JCreator LE 2.5.0 , Java SDK 1.5 I can't seem to get the HelloWorld example to run. In Jcreator it will compile fine, but when I try to run it from the IDE it doesn't work. I put the jogl.jar in: D:\Program Files\Java\jdk1.5.0_03\jre\lib\ext I also put the dll in:D:\Program Files\Java\jdk1.5.0_03\jre\bin I also added the jar file to the library tab in the project settings inside Jcreator The error message I get is: 1

to get lwjgl working on my comp i would have to put all the lwjgl files in with the class file on execution .. is a similar thing possible with xith?
UPDATE: made some progress, i put the vecmath jar in xith/third-party/vecmath
and it got rid of the tuple3f error but now a new one popped up: NoClassDefError: net/java/games/jogl/GLEventListener

can you give a example of what it would look like to add the files into a bat?
also for lwjgl, i could get things to compile in JCreator, with the library added to custom but they wouldn't execute unless i had all the lwjgl files in the same directory as the class and .java file. i wonder if the same will work for this?
