SWF Can't Access Network

Report · Oct 16, 2014

Hello, so I'm making a Flash game, and I got LAN connection to work, but for some reason when I upload the SWF to a website and try to access it, I get the whole "do you want to allow this to access the internet?" conformation box, except I can't actually change any of its settings. It's all blank and when I click on it nothing happens. Here is a screenshot:

I tried opening it on multiple computers, all of them get the same issue. Does anyone have any ideas why this is happening?

It was already set to that, no change. I also tried changing it to "access network only" but that didn't do anything either.

upload that to a file server that only loads your html and your swf.

what's that:

nc.connect("rtmfp:");

are you trying to create a peer-to-peer connection? or do you have a flash media server?

Report · Oct 17, 2014

Sorry, should have been more specific.

I'm trying to make a peer-to-peer connection. That "rtmfp:" thing is, according to the tutorial I used:

"...we can now attempt to create a new NetConnection object and connect to via Real Time Media Flow Protocol (RTMFP). RTMFP was developed by Adobe which basically enables low latency UDP streamings and direct P2P communication between multiple Adobe Flash Players and applications."

Report · Oct 17, 2014

that's wrong.

here's an excerpt from a book (Flash Game Development: In a Social, Mobile and 3D World) i wrote last year:

Peer-to-peer games

Since Flash player 10, you can create multiplayer games without the need of an intermediary server to facilitate player communication. The Flash player can use a protocol (Adobe's Real-Time Media Flow Protocol) that allows direct peer-to-peer communication.

Instead of using server-side code to handle the game logic and coordinate game state among players, each peer in the network handles their own game logic and game state and communicates that directly to their peers and each peer updates their game state based on the data received from others.

To use peer-to-peer networking each peer must connect with an Adobe server. Peer-to-peer communication does not go through that server (or it that would not be peer-to-peer) but peers must stay connected with the Adobe server in order to communicate with each other.

To communicate with the Adobe server you should use your own server URL and developer key. That URL and key can be obtained at http://www.adobe.com/cfusion/entitlement/index.cfm?e=cirrus.

Below is a simple tic-tac-toe game that uses Adobe's peer-to-peer networking to pair-up players. The NetConnection class is used to establish a connection to the Adobe server while the NetGroup class is used for peer-to-peer communication.

I used only a small part of the NetGroup methods for the tic-tac-toe game but there are more available if you are sharing data among many users and/or sharing large amounts of data.

here's part of the P2P class that shows how to use adobe's peer-to-peer:

var nc:NetConnection = new NetConnection();

// Add event listener to handle connections and data to and from this peer.

nc.addEventListener(NetStatusEvent.NET_STATUS,netStatusF);

// Use your server address and key (from Adobe, http://www.adobe.com/cfusion/entitlement/index.cfm?e=cirrus)

	const SERVER:String="rtmfp://p2p.rtmfp.net/";
	const DEVKEY:String="use your own development key";

nc.connect(SERVER+DEVKEY);

Thanks so much, I'll try this out and report back what happens. But I have one question, if I wanted to distribute this game out online or something, I want them to also be able to play peer-to-peer with each other. According to what you've written up, unless I'm reading it wrong, I would have to use my own address in the script, and that would just make MY internet connection work with peer-to-peer, but no one else's?

Report · Oct 17, 2014

you use adobe's address. they supply the servers that allows users to connect with each other.

again:

To use peer-to-peer networking each peer must connect with an Adobe server. Peer-to-peer communication does not go through that server (or it that would not be peer-to-peer) but peers must stay connected with the Adobe server in order to communicate with each other.

To communicate with the Adobe server you should use your own server URL and developer key. That URL and key can be obtained at http://www.adobe.com/cfusion/entitlement/index.cfm?e=cirrus

Alright, I've been playing around with it for a bit, so far I haven't used the package you set up, but I used my code I have written out and tried replacing the vars and such:

nc = new NetConnection();

var message:Object = {varName:'p1_up',value:p1_up};

nc.addEventListener(NetStatusEvent.NET_STATUS, netStatus);

const SERVER:String = "xxxx";

const DEVKEY:String = "xxxx";

nc.addEventListener(NetStatusEvent.NET_STATUS,connect);

nc.connect(SERVER+DEVKEY);

I don't get any errors or anything, up until I click on the "LAN multiplayer" button I have set up, which in the code is supposed to do this:

function click_lan_multiplayer(event:MouseEvent):void

{

multiplayer = "on";

if (m_switch1=="false")

{

group.sendToAllNeighbors( {varName: 'm_switch1', value: m_switch1});

m_switch2 = "false";

m_switch1 = "true";

gotoAndStop(101);

}

else

{

m_switch2 = "true";

gotoAndStop(101);

}

Basically, I have it set up so it decides who is player 1 and player 2 depending on who connects first. For some reason, when I click on the button, I get this error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

at Game_fla::MainTimeline/click_lan_multiplayer()

That did not happen before.

Do I have to use the package you have created, or can I just make some tweaks to the code I already have set up? If I have to use the package, I have no clue what I'm doing because when I paste it on the frame it says the package is "unexpected".

Thanks for all of your help so far either way.

Report · Oct 17, 2014

these need to be fixed:

const SERVER:String = "xxxx";

const DEVKEY:String = "xxxx";

and all your variables need to be declared.

Report · Oct 17, 2014

Oh no, ha ha the "xxxx" I put in just because I didn't think it would be a good idea to put in my developer keys in a public forum (unless it doesn't matter?), I have the actual ones pasted in the script in the Flash document.

And as for all of the variables being declared, I thought they all were already? The error goes away when I remove the "group.sendToAllNeighbors( {varName: 'm_switch1', value: m_switch1});" from the "function click_lan_multiplayer(event:MouseEvent):void". I'm pretty sure I just did something totally wrong with the whole internet connection thing...

Report · Oct 17, 2014

you must be calling click_lan_multiplayer before your group is defined.

in your netStatus function you should be defining your group when

event.info.code== "NetConnection.Connect.Success":

check my P2P class.

Report · Oct 17, 2014

Alright, but I know for a fact my click_lan_multiplayer is defined well before the button is clicked to call it. It works fine when I take out the "SendToAllNeighbors" line of it and it goes to the frame, but with that line in, I get the error.

As for the netStatus function, I do have a group defined in it, which is:

function setupGroup():void

{

var groupspec:GroupSpecifier = new GroupSpecifier("test");

groupspec.postingEnabled = true;

groupspec.routingEnabled = true;

groupspec.ipMulticastMemberUpdatesEnabled = true;

groupspec.addIPMulticastAddress("225.225.0.1:30000");

group = new NetGroup(nc,groupspec.groupspecWithAuthorizations());

group.addEventListener(NetStatusEvent.NET_STATUS,netStatus);

}

Is something coded incorrectly here?

Oh, just found something else interesting, when I have this set up:

I get the error. However, when I just have this one set up:

nc.connect("rtmfp:");

It works just fine. If I have two SWFs open, they will connect and play with each other fine. But again, I get that other internet problem with that, which is why I made this thread in the first place...
