I have tested a few values (by setting LwjglApplicationConfiguration width and height) to these values:
1920 | 1080
1024 | 768
800 | 600
But I'm not able to get below those values while setting the fullscreen mode on.
So, what are the supported fullscreen sizes for libGDX?
EDIT 1: this is the source code trying to create new application with resolution of 600|480
public class Main {
public static void main(String args[]) {
LwjglApplicationConfiguration cfg = new LwjglApplicationConfiguration();
cfg.title = "Asteroid";
cfg.width = 600;
cfg.height = 480;
cfg.resizable = false;
cfg.fullscreen = true;
new LwjglApplication(new Game(), cfg);
}
}
Which throws the following error:
Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: Couldn't set display mode 600x480, fullscreen: true
at com.badlogic.gdx.backends.lwjgl.LwjglGraphics.setupDisplay(LwjglGraphics.java:131)
at com.badlogic.gdx.backends.lwjgl.LwjglApplication.mainLoop(LwjglApplication.java:131)
at com.badlogic.gdx.backends.lwjgl.LwjglApplication$1.run(LwjglApplication.java:114)
On the other hand, similar code like this:
public class Main {
public static void main(String args[]) {
LwjglApplicationConfiguration cfg = new LwjglApplicationConfiguration();
cfg.title = "Asteroid";
cfg.width = 800;
cfg.height = 600;
cfg.resizable = false;
cfg.fullscreen = true;
new LwjglApplication(new Game(), cfg);
}
}
Works without problem.
You're trying to change the resolution of your monitor to something smaller than your monitor supports. Instead of changing the actual resolution of your monitor, you should simply use a viewport with whatever resolution you want.

I have 4 image sequences (png format) that I need to use for my animations. Each sequence is about 50 frames long and each frame is about 300x300, so I have something like 30 MB of resources to load. What's the most efficient way to load them to avoid memory leaks? Should I go for xml drawable animations or there's a better way?
I don't need to display all of them on the screen at the same time. Only one animation at time will be displayed.
Maybe is a bit late :) but I hope this can help other users.
At the end I've solved it with a simple loop which loads an image, draws it and destroy it.
int frames = 50;
//LOADING-REMOVING NEEDED FRAMES
//set animation range
i = currentFrame % frames;
//frame to cache
frameList.add(BitmapsLoader(i)); //custom function to load a specified frame from res
if (frameList.size() == 3) {
//frame to draw
canvas.drawBitmap(frameList.get(1), left, top, null);
//frame to remove
frameList.get(0).recycle();
frameList.remove(0);
}
This keeps the memory allocation stable, no matters how many frames your animation is. Obviously it costs more on CPU, as we're not pre-loading all resources but we keep loading them at each frame. Despite these facts, my app is running smoothly.
Tested on a Samsung Galaxy S3 and on a Galaxy Tab 4.
Thanks a lot.
I'm facing the same problem and after seen your answer for a while I have solved it by overriding an AnimationDrawable.
So, if the problem is you that can't load all images in array because it is too big for the memory to hold it, then load the image when you need it.
My AnimationDrawable is this:
public abstract class MyAnimationDrawable extends AnimationDrawable {
private Context context;
private int current;
private int reqWidth;
private int reqHeight;
private int totalTime;
public MyAnimationDrawable(Context context, int reqWidth, int reqHeight) {
this.context = context;
this.current = 0;
//In my case size of screen to scale Drawable
this.reqWidth = reqWidth;
this.reqHeight = reqHeight;
this.totalTime = 0;
}
#Override
public void addFrame(Drawable frame, int duration) {
super.addFrame(frame, duration);
totalTime += duration;
}
#Override
public void start() {
super.start();
new Handler().postDelayed(new Runnable() {
public void run() {
onAnimationFinish();
}
}, totalTime);
}
public int getTotalTime() {
return totalTime;
}
#Override
public void draw(Canvas canvas) {
try {
//Loading image from assets, you could make it from resources
Bitmap bmp = BitmapFactory.decodeStream(context.getAssets().open("presentation/intro_000"+(current < 10 ? "0"+current : current)+".jpg"));
//Scaling image to fitCenter
Matrix m = new Matrix();
m.setRectToRect(new RectF(0, 0, bmp.getWidth(), bmp.getHeight()), new RectF(0, 0, reqWidth, reqHeight), Matrix.ScaleToFit.CENTER);
bmp = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), bmp.getHeight(), m, true);
//Calculating the start 'x' and 'y' to paint the Bitmap
int x = (reqWidth - bmp.getWidth()) / 2;
int y = (reqHeight - bmp.getHeight()) / 2;
//Painting Bitmap in canvas
canvas.drawBitmap(bmp, x, y, null);
//Jump to next item
current++;
} catch (IOException e) {
e.printStackTrace();
}
}
abstract void onAnimationFinish();
}
Now to play animation you need to do what next
//Get your ImageView
View image = MainActivity.this.findViewById(R.id.presentation);
//Create AnimationDrawable
final AnimationDrawable animation = new MyAnimationDrawable(this, displayMetrics.widthPixels, displayMetrics.heightPixels) {
#Override
void onAnimationFinish() {
//Do something when finish animation
}
};
animation.setOneShot(true); //dont repeat animation
//This is just to say that my AnimationDrawable has 72 frames with 50 milliseconds interval
try {
//Always load same bitmap, anyway you load the right one in draw() method in MyAnimationDrawable
Bitmap bmp = BitmapFactory.decodeStream(MainActivity.this.getAssets().open("presentation/intro_00000.jpg"));
for (int i = 0; i < 72; i++) {
animation.addFrame(new BitmapDrawable(getResources(), bmp), 50);
}
} catch (IOException e) {
e.printStackTrace();
}
//Set AnimationDrawable to ImageView
if (Build.VERSION.SDK_INT < 16) {
image.setBackgroundDrawable(animation);
} else {
image.setBackground(animation);
}
//Start animation
image.post(new Runnable() {
#Override
public void run() {
animation.start();
}
});
That is all, and works OK form me!!!
I'm fairly new to programming in XAML and I'm making a test application on windows phone 8.1 emulator with a MapControl.
I wanted to add a MapIcon to my map but the icon doesn't appear when the map is zoomed out. I've searched the internet and couldn't find anything regarding my problem.
I want my zoomlevel 12 and show the mapicon on that zoomlevel.
namespace TEST.APPLICATION
{
public partial class MapView : Page
{
Geolocator geo = null;
public MapView()
{
this.InitializeComponent();
this.NavigationCacheMode = NavigationCacheMode.Required;
HardwareButtons.BackPressed += HardwareButtons_BackPressed;
}
void HardwareButtons_BackPressed(object sender, BackPressedEventArgs e)
{
if (Frame.CanGoBack)
{
e.Handled = true;
Frame.GoBack();
}
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
map.Center = new Geopoint(new BasicGeoposition()
{
Latitude = 51.5856935784736,
Longitude = 4.79448171225132
});
map.ZoomLevel = 12;
displaySightings();
}
private void displaySightings()
{
MapIcon sighting1 = new MapIcon();
sighting1.Location = new Geopoint(new BasicGeoposition()
{
Latitude = 51.5940,
Longitude = 4.7795
});
//sighting1.NormalizedAnchorPoint = new Point(0.5, 1.0);
sighting1.Title = "VVV";
map.MapElements.Add(sighting1);
}
}
Is there any way to make the MapIcon always visible?
The MapIcon is not guaranteed to be shown. It may be hidden when it obscures other elements or labels on the map.
For some stupid reason, Microsoft thought that labels and other map elements should outrank map icons when rendering the display. So, if you're making an app displaying the locations of all the nearby Starbucks, the name of the high school across the street from the Starbucks is more important than the pushpin, according to them.
You'll need to render the pushpins using XAML instead.
I am using custom camera in android.When i am capturing image with Flash_ON, the image is too dark almost black in Nexus 4 only.But it is fine on other devices.Please help me .
My code is given below :-
CameraInfo cameraInfo = new CameraInfo();
Camera.getCameraInfo(cameraId, cameraInfo);
Camera.Parameters parameters = camera.getParameters();
Size bestPreviewSize = determineBestPreviewSize(parameters);
Size bestPictureSize = determineBestPictureSize(parameters);
mSize = bestPreviewSize;
parameters.setPreviewSize(bestPreviewSize.width,.setPreviewSize(bestPreviewSize.width,
parameters.setPictureSize(bestPictureSize.width, bestPictureSize.height);
if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
} else {
parameters.setFlashMode(Parameters.FLASH_MODE_ON);
parameters.setSceneMode(Parameters.SCENE_MODE_AUTO);
parameters.setFocusMode(Parameters.FOCUS_MODE_AUTO);
}
camera.setParameters(parameters);
Just change the value of Parameter you need to set as follows
parameters.setFlashMode(Parameters.FLASH_MODE_TORCH);
Flash should turn off automatically. If it doesn't then turn off it manually in shutter callback
ShutterCallback shutterCallback = new ShutterCallback() {
#Override
public void onShutter() {
try {
Parameters params = camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_OFF);
camera.setParameters(params);
} catch (Exception e) {
}
}
};
I am trying to use a KinectColorViewer in a project using Kinect for windows (sdk 1.5). In the kinect explorer example, the KinectColorViewer componant had a KinectSensorManager component that is binded. In the xaml file we have:
<kt:KinectColorViewer x:Name="ColorViewer" KinectSensorManager="{Binding KinectSensorManager}" CollectFrameRate="True" RetainImageOnSensorChange="True" />
I have a lot of trouble reproduccing the same concept in other projects. I have used the Microsoft.Kinect.Toolkit's KinectSensorChooser, KinectSensorChooserUI and the Mirosoft.Sampels.Kinect.wpfviewers KinectColorViewer. Tried to bind the KinectSensorManager of The colorViewer to the UI element and follows.
<my:KinectColorViewer Width="200" Height="200" HorizontalAlignment="Left" Margin="198,12,0,0" Name="kinectColorViewer1" VerticalAlignment="Top" KinectSensorManager="{Binding ElementName=kinectSensorChooserUI1, Path=KinectSensorChooser.Kinect}" />
both attempts were unsuccesfull. Has anyone used the ColorViwer, DepthViwer and SkeletonViewer using the new SDK? Figuring that our would be great...
To bind the KinectSensorManager, I added the following code to the back end:
public partial class MainWindow : Window
{
public KinectSensorManager KinectSensorManager { get; set;}
private void WindowLoaded(object sender, RoutedEventArgs e)
{
KinectSensorManager = new KinectSensorManager();
KinectSensorManager.KinectSensorChanged += new EventHandler<KinectSensorManagerEventArgs<KinectSensor>>(KinectSensorManager_KinectSensorChanged);
// Look through all sensors and start the first connected one.
// This requires that a Kinect is connected at the time of app startup.
foreach (var potentialSensor in KinectSensor.KinectSensors)
{
if (potentialSensor.Status == KinectStatus.Connected)
{
this.sensor = potentialSensor;
break;
}
}
if (null != this.sensor)
{
// Turn on the skeleton stream to receive skeleton frames
this.sensor.SkeletonStream.Enable();
this.sensor.DepthStream.Enable();
this.sensor.ColorStream.Enable(ColorImageFormat.RgbResolution640x480Fps30);
this.sensor.AllFramesReady += new System.EventHandler<AllFramesReadyEventArgs>(sensor_AllFramesReady);
this.sensor.SkeletonFrameReady += this.SensorSkeletonFrameReady;
// Start the sensor!
try
{
this.sensor.Start();
}
catch (IOException)
{
this.sensor = null;
}
var kinectSensorBinding = new Binding("KinectSensor") { Source = this.sensor };
BindingOperations.SetBinding(this.KinectSensorManager, KinectSensorManager.KinectSensorProperty, kinectSensorBinding);
}
if (null == this.sensor)
{
this.statusBarText.Text = Properties.Resources.NoKinectReady;
}
}
and the Xaml file:
<kt:KinectColorViewer Width="191" Height="83" Grid.Column="3" KinectSensorManager="{Binding KinectSensorManager}" HorizontalAlignment="Left" Margin="17,236,0,0" Name="kinectColorViewer1" VerticalAlignment="Top" />
but I still dont get any color stream.
You binding statement is incorrect. "KinectSensorChooser.Kinect" is a reference to hardware (i.e., the Kinect) selected by the KinectSensorChooser -- it is not the KinectSensorManager.
You should be binding to the KinectSensorManager in the same way the examples show you. Is there something special you are trying to do that would lead you to bind it differently?
Your main class should start out something like this:
// automatically finds a Kinect for you
private readonly KinectSensorChooser sensorChooser = new KinectSensorChooser();
// the bindable sensor property
public KinectSensorManager KinectSensorManager { get; private set; }
public MainViewModel()
{
if (IsInDesignMode) {
// load design mode only content
}
else
{
// initialize the Kinect sensor manager
KinectSensorManager = new KinectSensorManager();
KinectSensorManager.KinectSensorChanged += this.KinectSensorChanged;
// locate an available sensor
sensorChooser.Start();
// bind chooser's sensor value to the local sensor manager
var kinectSensorBinding =
new Binding("Kinect") { Source = this.sensorChooser };
BindingOperations.SetBinding(
this.KinectSensorManager,
KinectSensorManager.KinectSensorProperty,
kinectSensorBinding);
}
}
#region Kinect Discovery & Setup
private void KinectSensorChanged(object sender,
KinectSensorManagerEventArgs<KinectSensor> args)
{
if (null != args.OldValue)
UninitializeKinectServices(args.OldValue);
if (null != args.NewValue)
InitializeKinectServices(KinectSensorManager, args.NewValue);
}
// Kinect enabled apps should customize which Kinect services it initializes here.
private void InitializeKinectServices(
KinectSensorManager kinectSensorManager,
KinectSensor sensor)
{
// Application should enable all streams first.
// configure the color stream
kinectSensorManager.ColorFormat =
ColorImageFormat.RgbResolution640x480Fps30;
kinectSensorManager.ColorStreamEnabled = true;
// configure the depth stream
kinectSensorManager.DepthStreamEnabled = true;
kinectSensorManager.TransformSmoothParameters =
new TransformSmoothParameters
{
Smoothing = 0.5f,
Correction = 0.5f,
Prediction = 0.5f,
JitterRadius = 0.05f,
MaxDeviationRadius = 0.04f
};
// configure the skeleton stream
sensor.SkeletonFrameReady += OnSkeletonFrameReady;
kinectSensorManager.SkeletonStreamEnabled = true;
}
// Kinect enabled apps should uninitialize all Kinect services that were initialized in InitializeKinectServices() here.
private void UninitializeKinectServices(KinectSensor sensor)
{
sensor.SkeletonFrameReady -= this.OnSkeletonFrameReady;
}

You can then bind to the manager from your View as shown by the examples.
You make need to also set the DataContext, by putting the following into the constructor:
DataContext = this;
I created a simple Rating user control, the problem this control won't in WinRT work when I use binding, it works fine on windows phone, This is my Control:
public sealed partial class RatingControl : UserControl
{
public int Rate { get { return (int)GetValue(RateProperty); } set { SetValue(RateProperty, value); } }
public static readonly DependencyProperty RateProperty = DependencyProperty.Register("Rate",
typeof(int),
typeof(RatingControl), null);
public RatingControl()
{
this.InitializeComponent();
this.Loaded += RatingControl_Loaded;
}
void RatingControl_Loaded(object sender, RoutedEventArgs e)
{
List<Image> Images = new List<Image>();
for (int i = 0; i < 5; i++)
{
Image img = new Image { Width = 35, Height = 35, Margin = new Thickness(3) };
img.Source = new BitmapImage { UriSource = new System.Uri("ms-appx:Images/Stars/notFilled.png") };
Images.Add(img);
sp.Children.Add(img);
}
for (int i = 0; i < Rate; i++)
Images[i].Source = new BitmapImage { UriSource = new System.Uri("ms-appx:Images/Stars/Filled.png") };
}
}
When I hardcode the value, it works fine:
<local:RatingControl Rate="3" />
but when I use Binding, it just shows zero stars. I checked the value of Rate, it is always zero.
<local:RatingControl Rate="{Binding Decor, Mode=TwoWay}" />
UPDATE: I just found out that the binding happens before I get the value of the Rate, so its zero all the time. How can I fix that? I need the binding to happens after I get the value. Also I thought the Binding happens everytime I change the Rate value.
SOLUTION: I Didnt implement the DependencyObject right, I should've done this:
public static readonly DependencyProperty RateProperty = DependencyProperty.Register("Rate",
typeof(int),
typeof(RatingControl), new PropertyMetadata(0, new PropertyChangedCallback(BindRateControl)));
SOLUTION: I Didnt implement the DependencyObject right, I should've done this (adding a callback method):
public static readonly DependencyProperty RateProperty = DependencyProperty.Register("Rate",
typeof(int),
typeof(RatingControl),
new PropertyMetadata(0, new PropertyChangedCallback(BindRateControl)));
has you try adding the UserControl from code-behind. this help you to ensure that the UserControl is triggered after getting the value.
