I'm new (obviously…) and am not sure what the problem is. I did notice that JmeBinaryReader was used to set the bounding to a box, which BinaryImporter doesn't do (if it does, I couldn't find it).
The actual problem crops up in the buildChaseCamera method
you can create a new BoundingBox after the model has been imported
I agree. I had the same problem initially. But once you create a new BoundingBox and update the modelbound it will solve the problem. However if it does not, then you are importing the model incorrectly. Just post that part of the code and I'll have a look. :)
Have you tried using the default directory containing the bike.3ds file as in the flagrush e.g. "jmetest/data/model/bike.3ds"? Why not use it from there? The only other thing I can think of is that either you have not put the bike.3ds in the resources/models/bike.3ds or either this directory is not in the build??
hmmm…i fixed it the specific error, but not the general one… after I post this, I'll try using ResourceLocator
i changed the file extension from .3ds to .jpg…and the URL error went away, but it is still causing a null pointer error when getting the world bound. I've debugged it a bit and the world bound is null, so
Alright could you post the whole code of the method where you are importing the .3ds file/creating your player? I think you are making a mistake there and thats why the chase camera is giving you null at:
still doesn't make sense that the system can find a .jpg file and not a .3ds
After I changed the extension to .jpg and changed the url to match, it did load the model.
player.getWorldBound() returns null
(null).yExtent causes null pointer error
here is the code:
Node model = null;
MaxToJme C1 = new MaxToJme();
ByteArrayOutputStream bytearrayoutputstream = new ByteArrayOutputStream(); //For loading the raw file
// File Path for the model
URL url = FlagRush.class.getClassLoader().getResource("resources/bike.jpg");
InputStream is = null;
try
{
is = url.openStream();
}
catch (Exception err)
{
System.out.println("Could not open Model file: " + err);
}
try
{
// Converts the file into a jme usable file
C1.convert(is, bytearrayoutputstream);
// Used to convert the jme usable file to a TriMesh
BinaryImporter binaryImporter = new BinaryImporter();
ByteArrayInputStream in = new ByteArrayInputStream(bytearrayoutputstream.toByteArray());
//importer returns a Loadable, cast to Node
model = (Node)binaryImporter.load(in);
}
catch (Exception err)
{
System.out.println("Error loading md3 model:" + err);
}
//set the vehicles attributes (these numbers can be thought of as Unit/Second).
player = new Vehicle("Player Node", model);
player.setModelBound(new BoundingBox());
player.updateModelBound();
player.setAcceleration(15f);
player.setBraking(25f);
player.setTurnSpeed(2.5f);
player.setWeight(25f);
player.setMaxSpeed(25f);
player.setMinSpeed(15f);
To be honest I cannot see anything wrong with your code - may be I am missing the same thing as you and more senior members could shed some light… In the mean time try out this, it worked perfectly for me when I used to practice the examples, should do the same for you if it doesnt we can rule this possibility out…
private void createPlayer()
{
Node model = null;
try
{
MaxToJme C1 = new MaxToJme();
ByteArrayOutputStream BO = new ByteArrayOutputStream();
URL maxFile = Ares.class.getClassLoader().getResource("jmetest/data/model/robot.3ds");
C1.convert(new BufferedInputStream(maxFile.openStream()),BO);
model = (Node)BinaryImporter.getInstance().load(new ByteArrayInputStream(BO.toByteArray()));
//scale it to be MUCH smaller than it is originally
model.setLocalScale(1.5f);
player = new Vehicle("Player Node", model);
player.setLocalTranslation(new Vector3f(138, 55, 112));
//Creating the CameraNode and attaching it to the player for the first person view as in FPS games
camNode = new CameraNode("camera Node", cam);
player.attachChild(camNode);
scene.attachChild(player1);
scene.updateGeometricState(0, true);
}
catch (IOException e)
{ // Just in case anything happens
System.out.println("Exception: !" + e);
e.printStackTrace();
System.exit(0);
}
}
ResourceLocator also will not open / find bike.3ds, it will find bike.jpg. both of those files are in the exact same location and are actually the same file, just the extension is altered.
I'm going to see if updating my jME libraries will help. I don't have a cvs client on this computer and don't have rights to install one. I'll just have to get them on my home pc and transfer to this one…
I'll go ahead and test the code on a couple other pc's and see if it is just this computer. I am currently running the build from oracle jdeveloper. I'll use eclipse at home and see if it helps. It would be unfortunate if jdeveloper was the problem though…it is the only ide I have at my disposal on this computer.
I did have it as MODEL, i gave up on the tutorial and just started on a project. I get the gist of how it should work. It was probably something unrelated to the code itself that I wasn't noticing.
