Jme physics for JME 2.0 -> No physics implementation was registered nor found

condeagustin · April 22, 2009, 4:57pm

Hello everyone

I have a problem with the jme physics for JME 2.0. The story is as follows. I already downloaded from SVN the latest source code of jme physics from http://code.google.com/p/jmephysics/ and I succesfully compiled it. Then I took that generated .jar file and I added it as a lib for my test project that has some physics basic testing (a box falling, and it already works perfect with JME 1.0). Then I succesfully compiled this test project and I already added the -Djava.library.path="libnatives" where the latest (from the mentioned SVN) odejava.dll is located, and of course I also added the latest (from the mentioned SVN) odejava-jni.jar, and when I run it, in the line

setPhysicsSpace( PhysicsSpace.create() );

I get this runtime error:

22/04/2009 11:30:41 AM com.jmex.physics.PhysicsSpace scanAvailableImplementations

GRAVE: Exception in game loop

java.lang.IllegalStateException: No physics implementation was registered nor found!

at com.jmex.physics.PhysicsSpace.create(PhysicsSpace.java:348)

Can someone help me? I mean I have read a lot of forums about jme-physics for JME 2.0 and I have followed all those indications, so I don't know what is happening. Please help, I want jme physics to work with JME 2.0. Farewell.

make sure -Djava.library.path is correctly set, i think you'll get that error if the .dll is not found

nymon · April 22, 2009, 10:08pm

You'll need to use the odejava.jar if I'm not mistaken, not the odejava-jni.jar.

condeagustin · April 23, 2009, 2:33am

Umm nope (nymon and Core-Dump) I already had that configured, so that was not the solution. Hey everyone, I finally solved this problem on my own and for those lost souls who suffered with this I'm going to explain the solution. For those others who are lazy and don't want to compile jme physics for JME 2.0 then you can email me and I'll send you the .jar or if there is an option to publish it on the internet I would do it without any prob.

First you have to download the source from http://code.google.com/p/jmephysics/source/checkout with SVN
Then you have to create a project of type class library in netbeans (I used this IDE). You can create it anywhere in your pc
Go to the downloaded source of step 1 and being on the root directory go to src and copy all its content and then paste it under the src folder of the project created in step 2.
Go to the downloaded source of step 1 and on the root dir go to impl/ode/src and copy all its content and then paste it under the src folder of the project created in step 2. If it asks to overwrite click on Yes everything
In the project of step 2, as a library (Add as a jar option in netbeans) add the odejava-jni.jar that already comes in svn/impl/ode/lib. And then with the same option add all the .jar libraries that come in the JME_2.0_Distribution.zip that you can download on http://code.google.com/p/jmonkeyengine/downloads/list
Compile the project succesfully and now you have your .jar for physics in JME 2.0 (my jar is called JME2Physics.jar!)

I was having that exception BECAUSE I didn't know I had to make step 4, I mean I wasn't including the source files for the IMPLEMENTATION!!! That is why the system never found any implementation of physics. And obviously don't forget that you have to add the -Djava.library.path for the natives and the odejava-jni.jar in the game/application that is going to use the JME2Physics.jar

Feel free for questions or suggestions. I hope this can help you. Farewell.

I definitely am too lazy right now and would appreciate a odejava.jar :)
You can use https://www.box.net/ or http://www.mediafire.com/ .

I'm trying to test https://sourceforge.net/projects/projecteva/ and have the same problem "INFO: Physics implementation 'com.jmex.physics.impl.physx.PhysXSpace$PhysXFactory' not present." etc

Thanks!

the odejava-jni.jar and dll's / so's can be found here:

http://code.google.com/p/jmephysics/source/browse/#svn/trunk/impl/ode/lib

odejava-jni.jar does not do the trick.. :(

Core_Dump · June 12, 2009, 7:19pm

and you did set -Djava.library.path to the path containing the native ode library ?

condeagustin · June 12, 2009, 11:57pm

Hello

I’m sorry for keep you waiting about the .jar. Here is the link where you can download it:

http://www.box.net/shared/kkqyv530gn

The file is called JME2Physics.jar and the is the physics that works perfect with JME2.0. I even tested it on mac, linux and windows and the physics works perfectly :D. Farewell

Agustin

condeagustin · June 13, 2009, 12:06am

Oh and this is the odejava-jni.jar that i’m using for JME 2.0 http://www.box.net/shared/ht9gynmgn3. If you need the native libs (for mac, windows and linux) for the physics to work in JME 2.0 just tell me and i will upload those too

Bye

No, but if I do, the game window doesn't even open (because it doesn't find lwjgl for some reason...)

I simply run java -jar eva.jar, and in a subfolder called lib/ there are

$ ls
JPhysicsBuild.jar gluegen-rt.dll jinput-raw.dll jogl_awt.dll libodejava.jnilib lwjgl.jar swt.jar
JavaAccessBridge.dll gluegen-rt.jar jinput.jar jogl_cg.dll libodejava.so lwjgl_util.jar xstream-1.3.1.jar
OpenAL32.dll jawtaccessbridge.dll jogl.dll jorbis-0.0.17.jar libodejava64.so lwjgl_util_applet.jar
fenggui-jme2.jar jinput-dx8.dll jogl.jar junit-4.1.jar lwjgl.dll odejava-jni.jar

I'm on arch linux 64bit and get http://pastebin.com/f733857d3 :|

Core_Dump · June 14, 2009, 10:45pm

does that work ?

java -jar -Djava.library.path=./lib -cp ./lib/* eva.jar

instead of ./lib/* you might list every single jar separated by ':'

I tried to use this file and get the same error! There is another thing i have to do?

condeagustin · July 23, 2009, 6:19pm

Well you also need the odejava-jni.jar file. I uploaded that one too. With those 2 files the physics should work in JME 2.0

jaimmeister · September 21, 2009, 8:48am

hello guys

i'm got an error here

altough i've already download all condeagustin said

and configure like this

-Djava.library.path = ./lib/native

lepe · October 3, 2009, 5:58am

I had the same problem. Did you fix it?

I fixed it removing all "final" methods from those functions in "com/jme/scene/Spatial.java" (so physics2 can override them)

For that, you need to use the source of JME instead of the library. Clean and Build again the project and should work!!

Do someone knows why those functions are "final"? is there any special reason for that?

Cheers.

sananoor_blr · March 18, 2010, 5:05am

hello… im new to jme physics… im getting the same error as above… i tried removing all d final methods … still not working… plz help

Please give more information. Are you using a 64bit windows system? If yes, you will have to open the Java Preferences and select 32bit Java as the preferred one, since ODE is compiled for 32bit only.

im trying to compile one of those jme demo it gives me same error as well

guys plz help.
