Hello,
I try to save & load a custom class like on this explanation : http://wiki.jmonkeyengine.org/doku.php/jme3:advanced:save_and_load#custom_savable_class
I also looked a lot on this forum but I didn’t find the good answer.
It’s working for save (check with dubug mode on Intellij) I can also see userData string field on my binary file .j3o.
private static FirstModel firstModel = new FirstModel();
/* ...
some code (init function)
*/...
Box cube1Mesh = new Box(1f, 1f, 1f);
Geometry cube1Geo = new Geometry("My Textured Box", cube1Mesh);
cube1Geo.setLocalTranslation(new Vector3f(-3f, 1.1f, 0f));
Material cube1Mat = new Material(assetManager, "Common/MatDefs/Misc/Unshaded.j3md");
cube1Mat.setColor("Color", ColorRGBA.Blue);
cube1Geo.setMaterial(cube1Mat);
cube1Geo.setUserData("le caca C super bon", firstModel);
rootNode.attachChild(cube1Geo);
/* ...
some code (other function)
*/...
String userHome = System.getProperty("user.home");
BinaryExporter exporter = BinaryExporter.getInstance();
File file = new File(userHome+"/Models/MyModel1.j3o");
try {
exporter.save(jmeApp.getRootNode(), file);
} catch (IOException ex) {
}
But not for loading. I can see the key on my Spatial (Geometry) userData but value is null.
public class HelloWorld extends SimpleApplication {
private static FirstModel firstModel;
public static void main(String[] args) {
HelloWorld app = new HelloWorld();
app.start();
}
public Geometry player;
Boolean isRunning=true;
@Override
public void simpleInitApp() {
BinaryImporter imp=BinaryImporter.getInstance();
imp.setAssetManager(assetManager);
String userHome = System.getProperty("user.home");
BinaryImporter importer = BinaryImporter.getInstance();
importer.setAssetManager(assetManager);
File file = new File(userHome + "/Models/" + "MyModel1.j3o");
try {
Node sceneNode = (Node)importer.load(file);
sceneNode.setName("My restored node");
rootNode.attachChild(sceneNode);
firstModel = ((Geometry)((Node) rootNode.getChildren().get(0)).getChildren().get(0)).getUserData("le caca C super bon");
System.out.println("test");
} catch (IOException ex) {
}
}
Note : It’s not the same application of JME (because project is an editor/launcher (save/load))
And this is the code of the CustomClass (same for editor & launcher) :
public class FirstModel implements Savable {
private int someIntValue; // some custom user data
private float someFloatValue; // some custom user data
private String someString;
//private Material someJmeObject; // some custom user data
public FirstModel() {
}
public void write(JmeExporter ex) throws IOException {
OutputCapsule capsule = ex.getCapsule(this);
capsule.write(someIntValue, "someIntValue", 1);
capsule.write(someFloatValue, "someFloatValue", 1f);
capsule.write(someString, "someString", null);
//capsule.write(someJmeObject, "someJmeObject", new Material());
}
public void read(JmeImporter im) throws IOException {
InputCapsule capsule = im.getCapsule(this);
someIntValue = capsule.readInt("someIntValue", 1);
someFloatValue = capsule.readFloat("someFloatValue", 1);
someString = capsule.readString("someString", null);
//someJmeObject = capsule.readSavable("someJmeObject", new Material());
}
}
