Re: mtasc Digest, Vol 50, Issue 3

[Scott Christensen-2]

Thanks for info on the flag.  It does make sense that the default is to either allow only access to the file system OR the internet.  

 

I've set the flag on my system to allow global access, but good to know users on the internet won't need to change it as everything on the internet for them.

 

I will take a look at projectsprouts.org

 

Another question, it appears Actionscript doesn't have any background threads? Any thoughts on loading assets in the background for a MMORPG to minimize delays?

You probably need to update your local trust cfg file. It's in
different places on different OSes and for different player vesions.

Here is more info:
http://www.abdulqabiz.com/blog/archives/flash_and_actionscript/flash_player_trust_f.php

This problem usually appears with code that is attempting to load
content from both the network and the file system. I believe the
desktop Flash Player will automatically configure itself to support
whichever operation happens first.

If you'd like to avoid this problem and many, many others, you might
want to check out http://projectsprouts.org which is a tool set that
automates the build (and much more) for ActionScript 2, ActionScript 3
and Flex projects.


Good Luck,

MTASC : no more coffee break while compiling

[Luke Bayes]

Background threads....

First thing is that you're in a single-threaded environment and you're
not really getting out of that.

The good news is that downloads do happen in a separate process, so
they don't lock up the UI.

In the past, we have built Finite State Machines, and Asynchronous
Command Queues for long-running background-ish processes.

Given these two patterns, I'd say the Command Queue proved most
flexible and useful for us.


Pseudocode for CommandQueue with clients:


// Dispatches a COMPLETED event
interface Command {
    function execute():void;
}

// Dispatches a COMPLETED event whenever queue is empty
class CommandQueue {
    public function push(command:Command):void {
        // add listeners and execute
    }
}


class Main {

    public static function main() {
        var queue:CommandQueue = new CommandQueue();
        queue.addEventListener(COMPLETED, queueCompletedHandler);
        var assetLoader:Command = new AssetLoader('assets/foo.png');
        var xmlLoader:Command = new XMLLoader('xml/foo.xml');
        queue.push(assetLoader);
        queue.push(xmlLoader);
    }

    private function queueCompletedHandler(event:Event):void {
        // Queue is complete, do other work
    }
}


Good Luck,
