Does anyone know how to set the canvas full screen in HTML5 LibGDX?
I only find width and height property in GwtApplicationConfiguration.
I'm using a Stage so I had to use an InputMultiplexer to send input to both my Stage and the InputAdapter that handles fullscreen GWT requests.
InputAdapter webGlfullscreen = new InputAdapter() {
#Override
public boolean keyUp (int keycode) {
if (keycode == Keys.ENTER && Gdx.app.getType() == ApplicationType.WebGL) {
if (!Gdx.graphics.isFullscreen()) Gdx.graphics.setDisplayMode(Gdx.graphics.getDisplayModes()[0]);
}
return true;
}
};
Gdx.input.setInputProcessor(new InputMultiplexer(webGlfullscreen, stage));

I have a class called AbstractGameScreen with the following signature:
public abstract class AbstractGameScreen extends InputAdapter implements Screen { ... }
All my screens extend this abstract class. Now the problem i am encountering is that in screens that use stages i already set the stage to be the inputprocessor. But if i do so, the keyUp method doesn't execute on back-key being pressed anymore. if i set the screen to be inputprocessor instead, the stage doesn't work. how do i work around this problem?
public class MenuScreen extends AbstractGameScreen {
#Override
public void show() {
stage = new Stage(new StretchViewport(Constants.VIEWPORT_GUI_WIDTH, Constants.VIEWPORT_GUI_HEIGHT));
Gdx.input.setInputProcessor(stage);
Gdx.input.setCatchBackKey(true);
instructionsVisible= false;
rebuildStage();
}
#Override
public boolean keyUp (int keycode) {
// Back to Menu
if (keycode == Input.Keys.ESCAPE || (keycode == Input.Keys.BACK && instructionsVisible)) {
instructionsVisible=false;
layerInstruction.setVisible(false);
layerControls.setVisible(true);
}
else
{
Gdx.app.exit();
}
return false;
}
In this case you need two InputProcessors- the Stage and your AbstractScreen. The way you do this is create a new InputMultiplexer object and configure it something like this:
InputMultiplexer multiplexer = new InputMultiplexer();
multiplexer.addProcessor( stage );
multiplexer.addProcessor( this ); // Your screen
Gdx.input.setInputProcessor( multiplexer );
In my Xamarin Forms Android project I am showing a Map using CustomMapRenderer. I am popping up a Info Window in Map screen and this info window has button name called "Call". I need to do a "OnCLick" button click operation for this button. I have googled it, but unfortunately I didn't come across any solutions. at last I have started to work on converting the Android Native code -Java into Xamarin Forms Android - c#, for this conversion I have been using this answers Google Maps Android API v2 - Interactive InfoWindow (like in original android google maps) . This converted code shows A field initializer cannot reference the non static field, method or property OnInfoWindowElemTouchListener.onClickConfirmed(view, marker) this Error inside Java.Lang.Runnable please help me to resolve the problem.

I have implemented the Task.Factory.StartNew instead of Android Runnableand now I am stucking on the below lines. I am struggling on converting this below Java codes into C#since it is written by Anonymous class concept.
Java
this.infoButtonListener = new OnInfoWindowElemTouchListener(infoButton,
getResources().getDrawable(R.drawable.btn_default_normal_holo_light),
getResources().getDrawable(R.drawable.btn_default_pressed_holo_light))
{
#Override
protected void onClickConfirmed(View v, Marker marker) {
// Here we can perform some action triggered after clicking the button
Toast.makeText(MainActivity.this, marker.getTitle() + "'s button clicked!", Toast.LENGTH_SHORT).show();
}
};
this.infoButton.setOnTouchListener(infoButtonListener);
infoButton in code is Call button
C# - Please help me to resolve the problem by converting/using(How to use) the above java code
The solution is too complicated for this window. Please see chat room for step by step solution.

I want a timer that switches screens after a certain amount of time. Here is the code for my splash screen:
private boolean timerIsOn = false;
And here is the render() method code:
if(!timerIsOn) {
timerIsOn = true;
Timer.*schedule*(new Task() {
#Override
public void run() {
*changeScreen*();
}
}, 15);
} else if(Gdx.input.isTouched()) {
// Remove the task so we don't call changeScreen twice:
Timer.instance().clear();
*changeScreen*();
}
}
I'm getting red swiggly lines under the parts of the code that have * and * surrounding them but the suggested action to fix it doesn't help.
Also, if you know of an easier way to make this work or possibly a tutorial that would be great as well.
I am setting handlers for single touch in this way
auto touchListener = EventListenerTouchOneByOne::create();
touchListener->setSwallowTouches(true);
touchListener->onTouchBegan = CC_CALLBACK_2(MyClass::onTouchBegan, this);
touchListener->onTouchMoved = CC_CALLBACK_2(MyClass::onTouchMoved, this);
touchListener->onTouchEnded = CC_CALLBACK_2(MyClass::onTouchEnded, this);
auto dispatcher = Director::getInstance()->getEventDispatcher();
dispatcher->addEventListenerWithSceneGraphPriority(touchListener, this);
For iOS it works properly, but for Android if I touch the screen with two fingers in the same time it will call onTouchBegan twice.
How can I disable multitouch from cocos2d-x (3.2) code for Android?
I found a workaround, since cocos2d-x doesn't have an official solution for this. (using Cocos2d-x 3.2)
Since each touch has it's own ID, we just need to filter first touch ID from others.
I have achieved this in the following way:
Created layer's instance variable:
int _currentTouchID;
Initialised it with -1 in layer's init() method:
_currentTouchID = -1;
In the beginign of all touch handlers I did next:
bool MyClass::onTouchBegan(cocos2d::Touch *touch, cocos2d::Event *event)
{
if (_currentTouchID < 0) {
_currentTouchID = touch->getID();
}
else {
return false;
}
//Your code here
return true;
}
void MyClass::onTouchMoved(cocos2d::Touch *touch, cocos2d::Event *event)
{
if (_currentTouchID != touch->getID()) {
return;
}
//Your code here
}
void MyClass::onTouchEnded(cocos2d::Touch *touch, cocos2d::Event *event)
{
if (_currentTouchID == touch->getID()) {
_currentTouchID = -1;
}
else {
return;
}
//Your code here
}
That's it. Please provide your solution if you have found a better one.
BTW: Commenting the switch case MotionEvent.ACTION_POINTER_DOWN: in Cocos2dxGLSurfaceView.java file,
as it was offered on cocos2d-x forum, didn't work for me.
I have CCScrollView with container with CCControlButtons, when the buttons scroll out of the visible CCScrollView area, They are also can be touched too. How can I control the area ?
Inspired by Tomasz's answer, I created an alternative solution, also inheriting from CCControlButton:
bool ScrollableButton::isTouchInside(CCTouch *touch) {
return !dragging && CCControlButton::isTouchInside(touch);
}
bool ScrollableButton::ccTouchBegan(CCTouch *touch, CCEvent *event) {
dragging = false;
return CCControlButton::ccTouchBegan(touch, event);
}
void ScrollableButton::ccTouchMoved(CCTouch *touch, CCEvent *event) {
if (!dragging && ccpDistance(touch->getLocation(), touch->getStartLocation()) > 25) {
dragging = true;
}
CCControlButton::ccTouchMoved(touch, event);
}
void ScrollableButton::ccTouchEnded(CCTouch *touch, CCEvent *event) {
CCControlButton::ccTouchEnded(touch, event);
dragging = false;
}
void ScrollableButton::ccTouchCancelled(CCTouch *touch, CCEvent *event) {
CCControlButton::ccTouchCancelled(touch, event);
dragging = false;
}
The secret sauce is the override of the isTouchInside function, which will return false even if the touch is inside, but was moved. This way, the button will also release its "zoomed" state as soon as you start scrolling.
It also adds a small tolerance factor, so if the touch moves just a little, it's still considered a "click". This factor is hardcoded at 25 in the example above.
My problems:
There is a scrollView with many buttons (items). Above it there are 2 function buttons (return, start).
When I scroll down item buttons overlie function buttons. When I swallow all touches above my scrollview I will lose my function buttons. So I have to find another solution.
When I start draging scroll view a item button is pressed. When I ended the button action will be execute. This is very annoying.
But there is the solution. I have created new CCControlButton. It checks whether was clicked outside scrollview or was dragged. The button is used for items buttons.
bool ControlButtonForScrolling::checkIfTouchIsInsideScrollView(CCTouch *pTouch)
{
CCPoint touchLocation = pTouch->getLocation(); // Get the touch position
touchLocation = _scrollView->getParent()->convertToNodeSpace(touchLocation);
CCRect bBox=_scrollView->boundingBox();
bool result = bBox.containsPoint(touchLocation);
return result;
}
bool ControlButtonForScrolling::ccTouchBegan(CCTouch *pTouch, CCEvent *pEvent)
{
bool isInside = this->checkIfTouchIsInsideScrollView(pTouch);
if (isInside) {
return CCControlButton::ccTouchBegan(pTouch, pEvent);
}
else
{
return false;
}
}
void ControlButtonForScrolling::ccTouchMoved(CCTouch *pTouch, CCEvent *pEvent)
{
CCControlButton::ccTouchMoved(pTouch, pEvent);
_scrollWasDragged = true; // information about dragging is stored to prevent sending action
}
void ControlButtonForScrolling::ccTouchEnded(CCTouch *pTouch, CCEvent *pEvent)
{
// this method is a copy of CCControlButton::ccTouchEnded except lines with _scrollWasDragged
m_eState = CCControlStateNormal;
m_isPushed = false;
setHighlighted(false);
if (!_scrollWasDragged)
{
if (isTouchInside(pTouch))
{
sendActionsForControlEvents(CCControlEventTouchUpInside);
}
else
{
sendActionsForControlEvents(CCControlEventTouchUpOutside);
}
}
_scrollWasDragged = false;
}
