UnityShared.swc; Communicating between Unity Flash Content and AS3.

Wow thanks for this. Unfortunately I'm getting a little red box with "Fatal Error : null" when I try compile this or just run the swf provided. Any idea where I may have gone wrong?

 

Silly me. Forgot I had 11.2 beta build installed. Cheers.

-edit- hmm actually runs fine in 11.2 content debugger. just null errors in browser.

 

Thank Ralph,

You can send and receive an arguments with this method (Replace WWW WWWForm) ?

 

Ok Sorry Ralph !!

 

Hi Ralph! Thank you for your post.
Can you tell us, is it possible now to integrate compiled stage3d layer (that unity builds) with native flash GUI?
I mean in FlashDevelop or FlashBuilder

 

Thank you a lot, Ralph!

 

@UnityRalph : Ok, no problem

 

If you provide other examples I would be very happy: D ...

 

i'm trying to run the example in ie8 with the flash debugger and running vizzy flash tracer but when i click the button, nothing seems to happen.
any ideas on what i'm doing wrong?

 

Thanks Ralph.

 

Hi Ralph,

This is really good stuff - just one more question:
Via the sendMessage method what sort of objects could I theoretically push accross from Flash to Unity? I'm thinking images (loaded from web or created) or audio files... is that possible? As a kind of WWW. replacement as it's missing in the current release?

Thanks!

 

so i went back and reinstalled the setup and followed the instructions and as far as i can tell, it's still not working:

Install "content debugger" from Adobe Flash Player [used ie9]:
Check
Go to http://flashplayerversion.com/, and make sure that it says 'Debugger: Yes': [says WIN 11,1,102,55]
Check
Create a file called mm.cfg and added ErrorReportingEnable=1; TraceOutputFileEnable=1
Check

i drag the AS3Communication.html into the browser, it loads up, it says running the in the debug player at the bottom right of the screen.
i click the button a few times

Find and open your flashlog.txt
it says: Player: init engine [space] MolehillGfxDevice: DirectX9 (Direct blitting)

is this "Player: init engine MolehillGfxDevice: DirectX9 (Direct blitting)" the result i'm looking for? this appears before i press the button and only appears on load so i'm assuming the expected result would be different.

 

I mentioned this in another thread but what would be really cool is to develop another api inside AS3 towards unity. In other words, an api targeting AS3 developers.

I realise the current priority would be to assist unity developers in exporting from unity to flash, but there is a whole new market opened up here - for targeting AS3 developers. In other words the starting context would not be Unity but the Flash paradigm (Flex/.FlashDevelop) and the goal would be importing and controlling unity generated assets (AS3 files, etc).

In both cases the end result is still Flash (swf/swc etc), but the difference being that one uses AS3 to write important code, rather than C# and Javascript (or in addition to such).

Hi Ralph, Thanks for the response. I'd need to load a texture from internet (created by a script) onto an object as part of the thing that I'm working on so can't do it in just all in AS3, so was thinking to load it in AS3 and push image object over to Unity for it to display on object. I guess it's simliar to the video texture example you've mentioned so I'll wait for that

Thanks again for the quick response!

 

i haven't edited any source yet. i've just simply downloaded, extracted and dragged the swf and html files into the browser. I've tried this at work at home and still no luck lol. I have cs4 installed so i'm thinking something may be blocking the traces. i'll try it on another machine with almost nothing installed and see if it works. Thx for the replys btw

 

@UnityRalph, thanks Ralph. I look forward to the evolution of the Unity/Flash feature. The current iteration is great and there is plenty to test and play with. It's the best xmas present I've had in years. cheers.

 

I was able to duplicate what the SimpleLoader.as does in Adobe Air With ActionScript3 ONLY project. Worked great... i can use other actionscript only classes and popup my own as3 only gui on top unitycontent...

But when i try to do the same thing in a Flex Application (Air 3.2 or 3.1)... Once it execute the comple function:

private function onUnityContentLoaderComplete(event:Event):void
{
uix.addChild(unityContentLoader);
unityContentLoader.unityContent.setContentHost(this);//Set this instance as the callback handler for unity.
}


where uix is a <mx:UIComponent>

IS DOES NOT SHOW THE SCENE... JUST WHITE BACKGROUND...

Any thoughts on loading the unity content in a flex application?

 

Thanks Ralph ...

Can't wait to see what you come up with.

Running unity content in as3 project is awesome ... Doing it in a flex app would be "off the hook"... The types of apps you will be able to make will be insane...

I love unity3d

 

Just to post my sample code: No Errors but just cant see unitycontent...

Also.. The commination still happens... can send messages to unity content....

Weird... Only in flex application is this a problem.... PURE AS3 work perfect!

I have two question:
1. how to get the attribute value in a Anonymous Object in c#
2.how to sendmessage to flash ,I read the code, but do not quite understand

FlashHelper.EmitAsm("SendToFlashScript$responder$['unityHelloFunction']({0})",this);

How to use FlashHelper.EmitAsm to recive/send message,The official did not elaborate example

 

Hello World !

you have no other examples please?

 

Hi!
I have some problems trying to build this exemple : when I try it it Firefox, it tells me :"Fatal Error : Error: Stage3D Error : Error #3702: Context3D non disponible. (did you set a correct wmode?)
at com.unity::UnityContent/onStage3DError()"

I have a content debugger and the wmode set to direct.
I'm not sure that I'm publishing the swf with the good version. I don't know how to set it (I'm building with FlashBuilder SDK: Flex 4.6)

If someone could help me...
Thanks in advance,

 

Can someone explain how to use this to change the default loading picture and bar?

thanks

 

So how do I read the object that I get back in unity? I've tried just about everything I can find to read the data from it.

 

Same here, I've tried everything I know and research about it but nothing seems to work... Please somebody help us with this

 

This is how I am doing it.
In ActionScript

Code (csharp):

1.  
2. var msgId:int = 123;
3. var msgString = "Hello World";
4. unityContentLoader.unityContent.sendMessage( "FlashConnection", "OnFlashMessage", {id:msgId, msg:msgString} );

FlashConnection is the name of the GameObject in Unity.
OnFlashMessage is the name of the function that gameobject that will be called
I am sending 2 parameters, an integer and a string (id and msg)

In Unity

Code (csharp):

1. public class FlashConnection : MonoBehaviour {
2.     public int idFromFlash = 0;
3.     public string msgFromFlash = "";
4.    
5.     void OnFlashMessage( object o ){
6. #if UNITY_FLASH
7.         FlashHelper.EmitAsm("FlashConnection$msgFromFlash$ = {0}.msg;FlashConnection$idFromFlash$ = {0}.id;", o);
8.         Debug.Log("Recieved from Flash: " + msgFromFlash + " " + idFromFlash );
9. #endif
10.     }
11. }
12.  

This part seems strange, I would think since I have the object that I should be able to just grab data out of it without the EmitAsm, but I haven't found a way to avoid it. And storing the return values into public variables also seems a bit odd.

 

Hey thx for the answer, I was already doing something like that but didnt know i could do it in one line

FlashHelper.EmitAsm("SendToFlashScript$message$ = {0}.message", o);
FlashHelper.EmitAsm("SendToFlashScript$chatName$ = {0}.name", o);
Debug.Log("Message: "+message+" - name: "+chatName);

But i was looking for a way to call a function within unity and send params without need to have everything on variables in the class

 

How are you building your flash project? with Flash Builder? Which SDK do you use?
I always have errors and I don't find why...

"Fatal Error : Error: Stage3D Error : Error #3702: Context3D non disponible. (did you set a correct wmode?)
at com.unity::UnityContent/onStage3DError()"

Thank you in advance

Martin

 

I'm using http://www.flashdevelop.org/

Didn't download anything but that, it installed some Flex library on its own during the install process.

I've seen that Stage3D error when you try to open the swf file in a browser directly instead of using the html page to view it.

 

Thank you a lot!
I'm using Flash Builder, I will try with FlashDevelop!

 

Flash Develop using the latest sdk 4.6 i think

 

Ok ! It works in flash player!

Thanks a lot for your help!

 

I hope this helps everyone shave a few hours off of testing

The following code works flawlessly to talk FROM unity3d TO flash

FlashHelper.EmitAsm("SendToFlashScript$responder$['PlayerMove'](SendToFlashScript$playerTransform$.position.x)");

SendToFlashScript is the class (SendToFlashScript.cs) ,
$responder$ is the flash object,
['PlayerMove'] is the Function Name,
(SendToFlashScript$playerTransform$ is the public variable called playerTransform,
and i can directly call .position.x on it

that is how you pass public variables from unity to flash

i wont bother explaining how to set values directly into that line of code instead of variables, because it would just confuse beginners. that line of code above is already going to be a workout.

 

Hello,

I'm successfully setting and calling functions both ways with the methods described above but the one thing I haven't yet successfully cracked is what sort of collections are supported both ways without throwing cast errors?
Trying to push an array of bytes (or chars... or anything in collection form..) from AS3 to Unity... not having any luck with AS3 Array.... Before I continue testing out other methods I just wondered if someone has "cracked" this one yet?

Thanks!
-Georg

 

Could you post an example any way for us "beginners"?

 

Hey Ralph... Any progress on how to use in a flex application?

 

I'm having some problems compiling with flashbuilder, I'm not experienced with flashbuilder at all.
I create a new actionscript project, add source folder as project folder, add unity swc file, swap main application file to preloader, set build version to 11.1.

Project appears to build fine but all I get is an image that says "your custom screen" in the html with nothing else.

What am I missing?

 

Can you share you files, trying to understand this better and not sure how "SendToFlashScript.cs" should be
