Legacy 1.x version of PlayN library.

PlayN is a cross-platform Java game development library written in Java that targets HTML5 browsers (via GWT), desktop JVMs, Android and iOS devices.

NOTE

This is the legacy 1.x version of the PlayN library which is no longer actively developed. Active development is happening on PlayN 2.x which is hosted at playn/playn.

Unless you mean to be using the legacy 1.x version of PlayN (and potentially submitting bug fix or other maintenance patches), you should immediately proceed to the 2.x site.

playn's Issues

PlayN tests fix Sound stop buttons in Android

here: https://github.com/threerings/playn/tree/master/tests/android
SoundTest buttons "Stop Loop Fanfare" and "Stop Loop Bling" does not works (can't stop looping sound).

Tested on mobile device and in Android emulator, same thing...

Detecting keyboard modifiers (Shift, Alt, Ctrl, etc)

I can't find out how to detect keyboard modifier clicks, if there isn't a way to do it, perhaps it could be implemented since its a very common feature required in game design.

I would have expected the modifiers to be returned in the Keyboard.Event

Cheers!

gamepad support?

Is gamepad support planned for playn?

I can propose an API and work on java and html implementation...

Raspberry Pi support (and others ARM devices too)

Hi,
I added support to openGL 2.0 ES on PlayN \o/
To do that I added 2 new files on java package (JavaGLES20 and JavaGLESContext).
I changed JavaImage(just a cast) and JavaGraphics (support to choose between normal and ES version) too.

Have you interest to get it on you project? I can send files to you :)

The big problem is get LWJGL ES version (because it is not on maven, you need to compile it by you self).

No documentation provided

I am keen on learning this tool but can't find any documentation on the wiki or on google even. Would be great to have somewhere to start.

If I have missed something just let me know! Thanks

Getting started still points at Google code site

The wiki page for getting started still points at the source code on Google code. It should point at the Github source code instead.

JavaStorage is volatile

JavaStorage saves to a temporary directory (/tmp on Linux) which means it's wiped after a reboot. It should probably go in the current or home directory.

[bug] invokes toString on an array

We find the following bug inside playn/html, the reason of this bug is the code converts an array (the return value of the method soundController.getPreferredSoundTypes() is an array) to a string directly, which will deliver the address of this array not the strings inside the array.

Path: playn/html/src/playn/html/HtmlAudio.java
Bug location: soundController.getPreferredSoundTypes() line 61

Code:
void init() { HtmlPlatform.log.debug("Preferred sound type(s): " + soundController.getPreferredSoundTypes());

Problems with onPause onAndroid

There is a problem when running a PlayN application on Android and onPause getting called due to visibility changed to invisible, for example when pressing the power button to lock the screen or if another app takes focus.

When this happens platform.graphics().ctx.onSurfaceLost(); will get called from GameViewGL.onPause(), which will clear all textures. When we resume after this the game looks ok, but as soon as the garbage collector runs the screen will turn black.

We have tried this with a blank project and it still occurs, though a bit harder to reproduce due to the garbage collector not being so interested in running when we use so little memory.

A temporary solution for us has been to add platform.graphics().ctx.onSurfaceCreated(); to GameViewGL.onResume(), don't know if this could create other problems though, if so we haven't seen them yet.

We have traced the adding of the platform.graphics().ctx.onSurfaceLost() call in GameViewGL to the following commit
c4310a8#L2R142

Make playn maven archetype generate GWT pom that's version specific

What steps will reproduce the problem?
html module generated by playn maven archetype replies on gwt-maven-plugin to decide on the GWT version which will causes compilation error if more 1 version of gwt is in the classpath

What is the expected output? What do you see instead?
maven playn skeleton to be generated successfully without errors (eg. ClassNotFoundException)

What version of the product are you using? On what operating system?
PlayN from trunk, Windows, Linux

Please provide any additional information below.

Attached is a patch that will generate pom for html module with gwt version configured as maven property default to 2.4.0, and force gwt-maven-plugin to use the specific version as indicated by maven property.

Following are traces from maven log when using the -X parameters

...

but then for some reason it decided to include gwt 2.4.0 in the classpath too

This patch will force gwt-maven-plugin to always use the version specified in gwt.version property

Created one issue with PlayN site as well, but guess i should be cancelling that one.

NullPointerException using PlayN.net().get(url,callback) API

Hi,

1.9-SNAPSHOT
robovm
iPhone 6 with iOS 8.1

Using the PlayN.net().get(url,callback)API the game hangs on the simulator and I saw the following stack several times (but not systematically) on the real device:

java.lang.NullPointerException 
 at playn.robovm.RoboNet$1.connectionDidFinishLoading$(RoboNet.java)

GPU/driver lacks sufficient vertex uniform vectors for QuadShader.

I just receive this error on the java backend after upgrading my game to a 1.5-SNAPSHOT, it was working fine with 1.4.

Is this error a result of my hardware, wich is kind of dated, or there was some change that could be triggering this?

Initialize platform components lazily

A game may not use all components provided by Platform.java, such as Audio , Net or Storage. Shall we make those components initialized lazily?

Silent games may exist, and I am working a case in which Audio is not used since no seeking is available and we need recording at the same time. Lazy initialzation also speeds up the startup although just a little.

Not sure those are in your designed use cases. If yes, I would like commit patches. If not, just close this issue.

Thanks.

Support for GIF Animations

Hey wondering if there would be a way to load a GIF image and animate it? It makes sense that this could be possible with Java, but to have this work on HTML is probably not as straight forward? Anyway appreciate any help I can get!

foreground color not working anymore using Canvas.fillText

Hi,

With 1.9-alpha1 / robovm / iOS 8

Canvas.setFillColor has no effect on the written text when using Canvas.fillText. Only black is supported as foreground color which makes text invisible on black background.

Layer.setScale(0) blows up in hit testing

I remember things were changed to allow setScale(0), but it still causes the game to asplode during hit testing on the next tick:

It should be a matter of doing a determinant check in GroupLayerImpl.hitTest, and possibly Layer.parentToLayer.

GroupLayer.addListener not working?

I'm trying to show some image layers in a group when this group is clicked:

    groupLayer.addListener(new Pointer.Adapter() {

        @Override
        public void onPointerStart(Pointer.Event event) {
            //set some child layer as visible
        }
    });

The onPointerStart callback is called only if setPropagateEvents is set to true and if a child is clicked.

GPU/driver lacks sufficient vertex uniform vectors for QuadShader

using play 1.5.1
as soon as I go for drawing anything on graphics(). it gives nullpointer exception with this warning
GPU/driver lacks sufficient vertex uniform vectors for QuadShader

[java] GPU/driver lacks sufficient vertex uniform vectors for QuadShader.

and the application goes into 'not responding' state(i m using window)

Possible issue with GroupLayerImpl

Currently this is how GroupLayerImpl looks like

/** This group's children. */
public List<L> children = new ArrayList<L>();

/**
* @return the index into the children array at which the layer was inserted (based on depth).
*/
public int add(GroupLayer self, L child) {
    // if this child has equal or greater depth to the last child, we can append directly and avoid
    // a log(N) search; this is helpful when all children have the same depth
    int count = children.size(), index;
    if (count == 0 || children.get(count-1).depth() <= child.depth()) {
      index = count;
    } else {
    // otherwise find the appropriate insertion point via binary search
    index = findInsertion(child.depth());
  }

  // remove the child from any existing parent, preventing multiple parents
  if (child.parent() != null) {
    child.parent().remove(child);
  }
  children.add(index, child);
  child.setParent(self);
  child.onAdd();
  return index;
}

There might be a potential issue of getting ArrayIndexOutOfBound when doing
children.add(index, child);

let's say the children is 5 in size, and the last one children[4] has a depth less than the child we are adding, so the index will be 5 and then we try to do
children.add(5, child)

we'll get ArrayIndexOutOfBound exception, it says in the javadoc of ArrayList
IndexOutOfBoundsException - if the index is out of range (index < 0 || index > size())

Possible fix, if this is an issue would be instead of
children.add(index, child);

we do
if (index >= children.size()) {
children.add(child); // this will add child to the last in the list anyway
}
else {
children.add(index, child);
}

Can some developer verify this please?

Shutdown GLView completely

I am trying port my application in which the game is integrated as a view controller. The game view will be shown as blank at the second time we run the game.

It is probably caused by GL drawing that is not shutdown completely. I did not find the equivalent function of gameView.Stop() in the Xamarin implementation.

The following is the code I used:

public class Demo extends UIApplicationDelegateAdapter {

private UIWindow window;

@Override
public boolean didFinishLaunching(UIApplication app, UIApplicationLaunchOptions launchOpts) {
    window = new UIWindow(UIScreen.getMainScreen().getBounds());
    window.setRootViewController(new MainController());
    window.makeKeyAndVisible();
    return true;
}

public static void main(String[] args) {
    NSAutoreleasePool pool = new NSAutoreleasePool();
    UIApplication.main(args, null, Demo.class);
    pool.close();
}

}

public class MainController extends UIViewController {

public MainController() {
    super();
    UIButton button = new UIButton();
    button.setTitle("Run", UIControlState.Normal);
    setView(button);
    button.addOnTouchUpInsideListener(new OnTouchUpInsideListener() {
        @Override
        public void onTouchUpInside(UIControl control, UIEvent event) {
            runGame();
        }
    });
}

private void runGame() {
    RoboPlatform.Config config = new RoboPlatform.Config();
    config.embedded = true;
    RoboPlatform platform = (RoboPlatform) PlayN.platform();
    platform = RoboPlatform.register(UIApplication.getSharedApplication(), UIApplication.getSharedApplication()
            .getWindows().get(0), config);

    // reference this to avoid GC collection.
    addStrongRef(platform);
    // Start the game
    Game game = new TheGame(this);
    PlayN.run(game);
    // We have to manually active the platform since it is embedded in our app.
    platform.activate();

}

private static class TheGame extends Game.Default {
    final private UIViewController from;

    public TheGame(UIViewController from) {
        super(30);
        this.from = from;
    }

    @Override
    public void init() {
        CanvasImage image = PlayN.graphics().createImage(200, 200);
        image.canvas().setFillColor(Colors.RED).fillRect(0, 0, 200, 200);
        ImageLayer layer = PlayN.graphics().createImageLayer(image);
        layer.addListener(new Pointer.Adapter() {
            @Override
            public void onPointerEnd(Event event) {
                UIApplication.getSharedApplication().getWindows().get(0).setRootViewController(from);
                RoboPlatform platform = (RoboPlatform) PlayN.platform();
                platform.terminate();
                PlayN.setPlatform(null);
                from.removeStrongRef(platform);
            }
        });
        PlayN.graphics().rootLayer().addAt(layer, 20, 20);
    }
}

}

Discrepancy in leading space rendering of layoutText

This is pretty easy to observe in the demo. Choose "Text Test" and click to enter a string with leading and trailing spaces, like " A ". Under java, just the "A" is rendered. Under ios, the " A" is rendered. Is it possible to make this consistent? It's causing problems for me in a styled text renderer in my app.

I'd prefer to include spaces in all rendering since that would allow the best control. Otherwise, I'd need to somehow measure a space and do special extra stuff during laying out each chunk, not pretty.

Error: uniform variables in vertex shader do not fit

Patch for mvn eclipse:eclipse to work

Hi guys,

I know this is a very trivial patch, but it really helps me to get mvn eclipse:eclipse to work. Currently without the following mvn eclipse:eclipse failed with the following nasty error

         Failed to execute goal org.apache.maven.plugins:maven-eclipse-plugin:2.8:eclipse (default-cli) on project playn-archetype

Guessing that it got some internal conflict when no maven eclipse plugin is specified. The fix is pretty simple, just add specify a version of maven eclipse plugin in playn/pom.xml would fix it.

         <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-eclipse-plugin</artifactId>
        <version>2.6</version>
        <configuration>
          <ajdtVersion>1.6</ajdtVersion>
        </configuration>
      </plugin>

If someone could help patch this in that'd be great, else people would have to manually put this in everything they do a git pull which could be rather annoying at times. Cheers

Automatically publish snapshots

Travis builds in response to commits, but doesn't publish its snapshots upstream. The one [current-version]-SNAPSHOT release is increasingly out of date, so things like tripleplay's travis build constantly fail.

(See also: tripleplay where I'm about to file a very similar issue since I have a TP-based project with a travis build that constantly fails thanks to both of these having out-of-date snapshots unless I pull cpu-wasting hackery such as https://github.com/deadmoose/bort/blob/ace9b8f05c7609210bb880b414f7d90fa81f5341/.travis.yml )

Issues with JavaAssetManager#setPathPrefix

This is how setPathPrefix looks like currently

 public void setPathPrefix(String prefix) {
    if (prefix.startsWith("/") || prefix.endsWith("/")) {
      throw new IllegalArgumentException("Prefix must not start or end with '/'.");
    }
    pathPrefix = prefix + "/";
  }

Shouldn't it be something like instead

 public void setPathPrefix(String prefix) {
    if (prefix.startsWith("/") || prefix.endsWith("/")) {
      throw new IllegalArgumentException("Prefix must not start or end with '/'.");
    }
    pathPrefix = prefix.length() > 0 ? prefix + "/" : prefix;
  }

Say if i have my image in src/main/resources/images/myface.png and i do

assetManager().setPathPrefix("");

so i can do
assetManager().getImage("images/myface.png");

i'll get thrown with exception saying it cannot find '/images/myface.png'. internally it's trying to get the resource from

getClass().getClassLoader().getResource("/images/myface.png");

which should really be

  getClass().getClassLoader().getResource("images/myface.png");

addBarrier behaves different in Java and HTML

I have this snippet of code:

  float DUR = 600;

  fanim.tweenScale(photo).to(0.25F).in(DUR).easeInOut();
  fanim.tweenXY(photo).to(-10, 370).in(DUR).easeInOut();
  fanim.tweenRotation(photo).to(-FloatMath.PI / 8).in(DUR);

  fanim.addBarrier(333); // wait for the current animations to finish and then wait another 333 ms

  fanim.tweenXY(photo).to(-300, 270).in(DUR).easeOutBack();
  fanim.tweenRotation(photo).to(-3 * FloatMath.PI).in(DUR);

The desired behaviour is to scale, move and rotate the photo (an ImageLayer) all three at the same time, then afterwards wait 333 ms, then again move and rotate it out of the screen.

In Java this works ok, but when I export to HTML, it doesn't wait the 333 ms between the two sets of animations

I set up a minimal project in github that showcases the problem:
https://github.com/tulsidas/tripleplay-barrier-demo

The code is extracted from the game that originated the problem.

There is a standard animation moving a circle, and if you click anywhere, it will take a snapshot of the screen and animate it.

On the java version it works properly, the snapshot goes to the corner, waits ~3 seconds, then goes away, but on the HTML backend it goes to the corner and immediatly goes away (not waiting the ~3 seconds)

I tried it both in Chromium 37 and Firefox 31, same wrong behaviour in both.

Looking and debugging into the JS generated code (attached) it seems (I'm mostly guessing) that the noActiveAnims flag (line 7878) is being wrongfully set to true when the "main" anim finishes, hence removing the secondary anim (the snapshot one) from the queue, and that's why it never finishes the waiting

Resizable window on java version?

What is the best way to have a resizable window with Java version? A lot of gamers like to play with maximized windon instead of fullscreen.

I tried to overrides Game.Default methods, it work more or less, but it does not play well with layers other than ImmediateLayer:

        @Override
        public void init() {
            Display.setResizable(true);
            super.init();
        }

        @Override
        public void paint(float alpha) {
            PlayN.graphics().ctx().setSize(Display.getWidth(), Display.getHeight());
            super.paint(alpha);
        }

Can no longer build using Maven

There are now missing dependencies that this version requires to build. I understand that this is legacy, but I'm sure some people are still using this version and need to be able to build it. The now missing dependencies and dependency changes are found here:

BenDol@29c69ac

I commited the dependencies from my location maven repo there.
