Last week i tried to start coding with the libgdx library.
As i would like to try it's 3d context i rode the tutorial of Xoppa: http://blog.xoppa.com/basic-3d-using-libgdx-2/
Well, i understood his examples and started to code in eclipse.
But as soon as i got to the modelbuilder usage i stuck:
#Override
public void create() {
...
ModelBuilder modelBuilder = new ModelBuilder();
...
}
i imported a few other classes without problems, but i didn't find ...g3d.utils.modelbuilder
I googled and took a look at their github, where the package g3d.utils. exists.
And now, i don't know anymore. i'm using the latest stable build 0.9.8
I hope you can help me. Thanks for your time!
The new 3D API (which is what Xoppa has been working on) is only available in post-0.9.8 builds, which at the moment is the "nightly" builds: http://libgdx.badlogicgames.com/download.html

I was trying to create and save an image with AnyChart for an android application. This image is created without being rendered since the idea is to use the data from a vector to generate the image and save it on the phone's memory. I am using Java for programming the android application.
I have been testing the ".saveAsPng()" and ".saveAsSVG()" functions from the Anychart Library but there has been no success... I don't receive an error but I don't get the image either... and I don't know exactly how to proceed...
I tried to follow this guideline (https://docs.anychart.com/Common_Settings/Server-Side_Rendering) but as I said, I haven't succeeded in generating and saving the file.
This is the code that I have been using:
private class CustomDataEntry2 extends ValueDataEntry {
CustomDataEntry2(double x, Number value) {
super(x, value);
}
}
_
List<DataEntry> dataLateral = new ArrayList<>();
for (int p=0; p<DataX.size();p++) {
dataLateral.add(new CustomDataEntry2(DataY.get(p), DataX.get(p)));
}
AnyChartView anyChartViewLateral = new com.anychart.AnyChartView(this);
APIlib.getInstance().setActiveAnyChartView(anyChartViewLateral);
anyChartViewLateral.setProgressBar(new ProgressBar(this));
Polar polarLateralImage = AnyChart.polar();
polarLateralImage.startAngle(90);
Linear xScaleLateral = Linear.instantiate();
xScaleLateral.minimum(-180).maximum(180);
xScaleLateral.ticks().interval(90);
polarLateralImage.xScale(xScaleLateral);
Line polarSeriesLine = polarLateralImage.line(dataLateral);
polarSeriesLine.closed(false).markers(true);
polarSeriesLine.markers().size(3);
polarLateralImage.autoRedraw(true);
anyChartViewLateral.setChart(polarLateralImage);
polarLateralImage.saveAsPng(400,400,0.3,"testImage.png");
Could anyone tell me what am I missing or what amb I doing wrong? I know I might be asking too much, but if it were possible, I would be happy if someone could provide a code snippet that works.
Thank you very much!
Unfortunately, the current version of the AnyChart Android native library doesn't support exporting features, it was no implemented yet.
I have been trying to call a Java method in unity. Not working for me, even the simplest example from the docs
using System.Collections;
using UnityEngine;
public class ExampleClass : MonoBehaviour {
void Start () {
AndroidJavaObject jo = new AndroidJavaObject ("java.lang.String", "some string");
int hash = jo.Call<int> ("hashCode");
Debug.Log ("hash=" + hash);
}
}
Unity console prints hash=0, which is not the hash code for provided String. Even if I change and use java.lang.StringInvalidClass as class name, unity still reports same result to the console without notifying errors. I can even try to call toString, toStringa, toInvalid2 and they always return empty string without showing errors.
This is a brand new 2d project with only script displayed above, attached to camara object. I am using Ubuntu, Unity 2019.4 and project platform is Android.
Thanks for the assistance.
Answering myself after some time working with unity.
All examples in the web and unity documentation doesn't mention it, which is weird since it is something simple to mention and about confusions: code needs to run as an android application. Editor or even unity remote does not work, in order to use AndroidJavaObject and related classes, your code needs to run as an android application installed in the phone.
I've been trying to get IAP to work with my LibGDX game for Android for over 6 hours. First I tried to use gdx-pay, but sadly the documentation for it is very unclear to me and was therefore not able to get it to work.
Because my games are only for Android (for now) gdx-pay was overkill anyway, so I decided to directly implement Google Play IAP. I found a tutorial that is pretty clear, but sadly it doesn't explain where I should put the IInAppBillingService.aidl file.
I tried putting it in a newly created directory in the Android directory, namely /android/vending/billing, but that doesn't seem to work and the directory also doesn't show when I have my project view on Android.
I also tried creating a new package "andoird.vending.billing" in the java directory where the game package with the AndroidLauncher is in but that doesn't work either.
With both these methods I'm not able to import the class IabHelper in the following tutorial code which is in AndroidLauncher.java located in my game's package:
String base64EncodedPublicKey = "xxx";
// compute your public key and store it in base64EncodedPublicKey
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
// Oh noes, there was a problem.
Log.d("IAB", "Problem setting up In-app Billing: " + result);
}
// Hooray, IAB is fully set up!
Log.d("IAB", "Billing Success: " + result);
}
});
Where (and how) am I supposed to put the "IInAppBillingService.aidl" file to be able to import the IabHelper class in my LibGDX project? If you have a clearer tutorial on gdx-pay or on a technique similar to the one I'm using now I would also appreciate it.
Thanks in advance!
I have some new questions in today's citymaps development.
In the Android studio,if I develop the code for citymap, there are always no logs showing but for others that does not happen. Why?
According to the citymaps official website, to create a map instance with CitymapsMapFragment, but in the sample project which citymaps provides, it uses SupportCitymapsMpaFragment ,What is the difference between them?
When the map is loading complete, is it automatically positioning to the current position or some other default position? Where is it?
If I open the GPS location，I can locate to the current position and show a blue arrow quickly, but too much power consumption,are there any other location way like network or base station location?
Code follows:
CitymapsMapFragment fragment = (CitymapsMapFragment)fragmentManager.findFragmentById(R.id.map);
if (fragment != null) {
fragment.setMapViewListener(this);
}
I did not find the fragment have the method setMapViewListener but setMapViewReadyListener,does it right?
Other code:
CitymapsMapView mapView = new CitymapsMapView(this, options, this);
When I add animate in additional methods like this：
mapView.setMapPosition(position, 300, new MapViewAnimationListener() {
#Override
public void onAnimationEnd(boolean completed) {
Log.d("SomeApp", "Move Complete!");
}
});
the project fails and exits,I tried to surround the code with try-catch block to catch exception for purpose, but nothing shows in logcat view. Why?
I am developer on the Citymaps project. I will do my best to answer all your questions
1) If you are not receiving log statements, this is likely an issue with your own application, IDE, or device configuration. In our own application, which uses the Citymaps SDK, we have no issues with logging.
2) Prior to using the Citymaps SDK, it is highly advisable that you familiarize yourself with fragments, but the short version is that SupportCitymapsMapFragment extends from the Fragment class in the v4 support library.
3) It is up to you to set the default position the map.
4) If you create a class which implements from the LocationSource interface, and then call mapView.setLocationSource, you can modify the behaviors of the map's location services. For an example, have a look at CitymapsLocationSource.java, which is the default implementation for this interface used by the SDK.
As for the exception you are having, you have not provided nearly enough information. Please show a stack trace, and I may be able to help.
Thank you for using our SDK, feel free to post again with any more questions.
For my bachelor thesis iam trying developing a JmonkeyGame.
4 weeks ago i read something about use a Character and use Physics ==> use BetterCharacterControl class.
Now my problem is that as soon as i implement statemanager.attach(bulletAppState):
#Override
public void simpleInitApp() {
bulletAppState = new BulletAppState();
stateManager.attach(bulletAppState);
initKeys();
initMouse();
initAudio();
createLight();
createTerrain();
createSky();
addPlayer();
addCamera();
}
I get an error on android.
I am developing in eclipse, not JME3-Programm because the game is only a part of the apk.
Libaries in eclipse:
JME3-android.jar, JME3-bullet.jar, JME3-core.jar
I have no idea where to look for a solution, or why this problem occours.
Help or tips to my problem would be fabulous.
Hardware:
Sony Compact D5503
Android V. 4.4.2
