I'm converting an actionscript 3 project to AS2 because AS3 is not yet scaleform compatible in CryEngine 3.
I have a MovieClip in the library. Under ActionScript linkage I have "Export for Actionscript" and "Export in frame 1" set, with the identifier "Notification" and nothing in "Class".
This code results in the error The class or interface 'Notification' could not be loaded.
var newMovieClip:MovieClip = new Notification();
stage.addChild(newMovieClip);
What is wrong with this code? It seems like a simple operation to create a MovieClip and add it to the stage, but it doesn't seem to be working properly.
In ActionScript 2 you need to use the attachMovie method (see docs). Your code would look something like this:
var newMovieClip:MovieClip = this.attachMovie("Notification", "newMovieClip", this.getNextHighestDepth());
Note that there's no addChild method in ActionScript 2; the displayList was added in ActionScript 3.

I've got a Xamarin Forms interface that defines a Bluetooth controller. I'm following the usual technique when trying to create an Android specific implementation of this (I will also do an iOS one when I get this working).
I define my interface as follows :
namespace ArduinoRobotController.Models
{
public interface BluetoothControllerInterface
{
List<string> GetPairedDevices();
..
Then I have my platform specific implementation like this :
[assembly: Xamarin.Forms.Dependency(typeof(BluetoothControllerInterface))]
namespace ArduinoRobotController.Droid.Implementations
{
public class BluetoothController : BluetoothControllerInterface
{
..
Then finally back in one of my view models, I have this code to get the platform specific instance I need :
BluetoothControllerInterface bt = Xamarin.Forms.DependencyService.Get<BluetoothControllerInterface>();
It builds and runs, but crashes on the line above. The error states :
System.MissingMethodException: Default constructor not found for type ArduinoRobotController.Models.BluetoothControllerInterface at SystemRuntimeType.CreateInstanceMono
.. etc.
I've tried lots of different ways around doing this, including calling to register the implementation in normal code rather than as [assembly etc. Any help on this really appreciated.
your registration needs to point to the concrete class, not the interface
[assembly: Xamarin.Forms.Dependency(typeof(BluetoothController))]
If I want to use Dart to create a js library, how can I export Dart classes and functions for use in javascript?
Is there something similar to scala.js, like this?
#JSExport
class Hello{
num x = 0
Hello(this.x)
}
So that in javascript, users can instantiate it as var hi = new Hello(1)
In case this is still relevant: You can use the dart2js compiler, which will compile your dart code down to ES.
In Module.php I have a some code (simplified version):
namespace Application;
use Zend\Mvc\ModuleRouteListener;
use Zend\Mvc\MvcEvent;
class Module{
public $somevariable = 'test';
public function onBootstrap( MvcEvent $e ) {
$this->somevariable = 'test2';
}
public function getValue(){
return $this->somevariable;
}
}
Next, I want to get value from variable "somevariable" in template layout.phtml. I do this as follows:
echo Application\Module::getValue();
but this doesn't work. What is wrong with that?
P.S. I never programmed much in PHP, so maybe I missed something :-(
you can use
$e->getViewModel()->setVariable('somevariable', 'somethingvalue');
and in the view :
echo $this->layout()->somevariable;
for detail, see this article : http://samsonasik.wordpress.com/2012/07/27/zend-framework-2-mvcevent-layout-view-get-namespace/
If a variable is just a string it doesn't make much sense to go with that approach. And please don't take this offensively, but if you don't have much experience in PHP (you tried to call a static function that is not static), then i wonder why you would start learning PHP with such a high class framework.
And if still you insist on doing that, please follow the official Documentation and read yourself through the whole QuickStart again and again. Check out some of the Modules out there and see how they do stuff.
Try to do the easy stuff first until you hit those points where you really need such functionality.
In the application I'm developing in Java SE I use Luaj to implement functionality (this is a data collector application). The Java app reads a COM port of a device and gives the data to Lua event handlers which are written by the user of the application. Part of the user interface is also constructed from Lua, however, I'm having problems adding ActionListener objects (implemented in Lua as well) to Swing components, like JButton.
The code I'm currenty stuck at:
button = luajava.newInstance("javax.swing.JButton","test")
visuals:getPanel():add(button)
This creates a JButton object and puts it on a JPanel component. I'd like to define the action listener for this button in Lua as well.
Any idea how I can do that?
I tried the following, but it obviously does not work.
al = {}
function al.actionPerformed(ev)
print("test")
end
button.addActionListener(al)
I come a bit late, but for the reference, the swingapp.lua script shows how to handle listeners:
button:addActionListener(luajava.createProxy('java.awt.event.ActionListener',
{
actionPerformed = function (e)
print('Action', e)
end,
}))
Tested with Luaj-jse 3.0-alpha1
I have a lingo script which runs some data processing for a Flash movie. I can call my Lingo functions from Flash by putting the following inside one of my methods:
getURL("Lingo: myMethod");
and I can pass parameters from flash to lingo as follows:
getURL("Lingo: myMethod param");
However, if myMethod returns a value, I can't seem to send it back to ActionScript. How do I code the following:
var myVar = getURL("Lingo: myMethod");
where myMethod is defined as:
on myMethod
--do something
return 5
end myMethod
We are using Flash 9 with CS 3.
You should be able to access Lingo via ExternalInterface assuming you're in Flash 8 or greater:
import flash.system.ExternalInterface;
var valueFromLingo = ExternalInterface.call("myMethod");
trace(valueFromLingo); // -> 5
#wulong:
the package is flash.external., not flash.system.
