Is there any easy way to show a selection box around an object?
Like maybe displaying the bounding box or simaliar?
A question to the code above:
TexCoords , why is this class missing (in my jme) :?
LightCombineMode.Off ;Mode.Strip,this.setVertexBuffer,this.setColorBuffer etc didn't work either
i have got the cvs jme2 version of cvs.dev.java.net
@problem above: i do it with find pick:
PickResults results = new BoundingPickResults();
results.setCheckDistance(true);
//scene: nodes where all the selectable things hang on
scene.findPick(ray,results);
if(results.getNumber() > 0) {
int i = 0;
float distance=results.getPickData(i).getDistance();
if(distance<110) {
//cast to my own node
CreatureModel creature= (CreatureModel) results.getPickData(i).getTargetMesh().getParentGeom().getParent().getParent().getParent();
//tell the node it is selected, there you can add bloom effect, lights, boxes, texts, etc.
creature.setSelected(true);
//change cursor
cursor=cursor0;cursorType=CursorType.FIGHT;}
}
You mean once you've clicked on a selectable object, like an enemy?
yes
I have no clue. When you find out, tell me. I'll be needing that rather soon! 
Without attaching any geometry, you could use another renderpass to render the object in a way to indicate it is selected. I guess you could render the bounding box in the pass. I haven't done that exactly, but Scene Monitor uses a render pass to highlight items in the scene that have been selected. Its a place to start at least.
What would be awesome (but not compatible on low-end machines) is to bloom the selected object. Make it really intense, so it's glowing. That would be sweet…
Ahh… finally found TerrainMarker. It’s from MonkeyWorld3d
http://monkeyworld3d.cvs.sourceforge.net/checkout/monkeyworld3d/monkeyworld3d/src/com/mw3d/core/spatial/TerrainMarker.java?revision=1.2
Here is the code modified to work with jME2.0
EDIT: I don’t think its working…
EDIT: Okay it compiles now, but the highlighting is a little funky - need to fix it…
EDIT: Works now, just forgot to set it to a triangle strip

TerrainMaker has highlighting or…?
I know a very used way today is by having a shader do a line draw around a selected object - if you get your hand on Rendermonkey the code seems pretty straight forward : ) Look under Non-photorealistic renders… and let us know how it goes hehe
EDIT: Found this in a different subject, where MrCoder mentions the shader in question (sorta) and there is a link at the top of the page http://www.jmonkeyengine.com/jmeforum/index.php?topic=8446.15
As far as i know jme2 is not on cvs.dev.java.net but on googlecode svn http://jmonkeyengine.googlecode.com/svn/trunk/ that would explain why you are missing some classes.
Hellmaster
now i got the svn version , I was years behind all the time XD and I didnt noticed it (damn jme wiki!)
New Problems followed:
anyone know why I can’t resolve javax.media? Do i have to use Eclipse RCP ? [solved]
and why does jme physics2 doesnt work with that jme version XD
“no lwjgl in java.library.path” (I added all libs and all of the lwjgl dir), I could cry :’(
(and I did:…Expand lwjgl.jar → Native Library Location → Edit → Workspace
The native libs are not directly in the "/lib" folder like the old messy 1.0. They are under separate folder underneath lib. For example, my mac has lwjgl's native lib set to: jme_SVN/lib/lwjgl/native/macosx (jme_SVN is just what I called my eclipse project.)
oh thxs , dummy me 
There is also a new physics version for jme2 which can be checked out at http://jmephysics.googlecode.com/svn/trunk
Hellmaster
thank you, now I am finally on the newest standards (hopefully
