as3isolib Actionscript 3 Isometric Library for Flash/Flex

as3isolib is a great isometric library for actionscript 3 by Justin Opitz.  This is a lower level isometric library that could be used in building your own isometric gaming engine or learning more about the popular isometric view in games or other flash content.

From building basic blocks…

To constructing sprites and objects with individual iso objects with their own bounding boxes.


This sample shows a two piece tree, a common issue with sprites in isometric is where to slice them up.  This sample shows a tree with the leaves able to be in front of a character so that you could walk under the tree and be in front of the trunk but covered by the trees.  Essentially height is respected.

Sample code for the tree tutorial:

package
{
        import as3isolib.display.IsoSprite;
        import as3isolib.display.primitive.IsoBox;
        import as3isolib.display.scene.IsoGrid;
        import as3isolib.display.scene.IsoScene;

        import flash.display.Loader;
        import flash.display.Sprite;
        import flash.events.Event;
        import flash.net.URLRequest;

        public class IsoApplication extends Sprite
        {
                private var scene:IsoScene;
                private var assets:Object;

                private var loader:Loader

                private function loadAssets ():void
                {
                        loader = new Loader();
                        loader.contentLoaderInfo.addEventListener(Event.INIT, loader_initHandler);
                        loader.load(new URLRequest("assets/swf/assets.swf"));

                }

                private function loader_initHandler (evt:Event):void
                {
                        buildScene();
                }

                private function buildScene ():void
                {
                        scene = new IsoScene();
                        scene.hostContainer = this;
                        scene.container.x = 200;
                        scene.container.y = 200;

                        var treeTrunkClass:Class = loader.contentLoaderInfo.applicationDomain.getDefinition("TreeTrunk") as Class;
                        var treeLeavesClass:Class = loader.contentLoaderInfo.applicationDomain.getDefinition("TreeLeaves") as Class;

                        var grid:IsoGrid = new IsoGrid();
                        grid.showOrigin = false;
                        scene.addChild(grid);

                        var s0:IsoSprite = new IsoSprite();
                        s0.setSize(25, 25, 65);
                        s0.moveTo(50, 50, 0);
                        s0.sprites = [treeTrunkClass];
                        scene.addChild(s0);

                        var s1:IsoSprite = new IsoSprite();
                        s1.setSize(125, 125, 100);
                        s1.moveTo(0, 0, 75);
                        s1.sprites = [treeLeavesClass];
                        scene.addChild(s1);

                        scene.render();
                }

                public function IsoApplication ()
                {
                        loadAssets();
                }
        }
}

current features

  • simple scene creation
  • 3 primitive types
  • base class for displaying user-created content
  • plenty of styling option on vector based primitives

So get busy building the flash version of roller coaster tycoon…

Google Now in the Casual Game Ads Market

Google has entered the flash gaming ads market.  Right now that is pretty much owned by MochiAds for flash game devleopers at least pre-game ads anyways.  Advertising can be annoying but MochiAds has pulled it off where the ads are usually advertising other games or interesting things and it monetizes game development for Flash, Unity3D, Director and others, which is a win.  There are many flash gaming sites that are great fun that use ads almost stylistically like Nitrome and typically the ads are pretty fast when they are during the game loading.

Although advertisements in games have long been a scurge on gamers fun when they are trying to insert them into fat client, immersive MMOGs where it totally takes away from the experience, that doesn’t work.

What does work is stuff like MochiAds and possibly Second Life type sponsorships, where advertisements are almost nostalgic or fun and integrated. Developers and publishers have to make money somehow, the better the experience the more impactful and the more games for all. The key is making the integration a good user experience.

We shall see how Google plans to do this.  This might go along with their Lively strategy. The ad market entrance in games is possibly what started the rumors that Google was going to buy Valve for Steam, rumors which quickly died down.

Anyways, the one good thing about this announcement is advertisments go to where the eyes and crowds are going or already at, they are apparantly going massively to online web games and causal experiences make for easy advertisment integration. TV, Radio and many other industries have been supported by advertisement interest due to consumers using and buying the content.  So online gaming is just another one of those entertainment industries and it will grow further with this news.

Hardware of the Casual Gamer Revisited from Unity3d Creators

A few weeks ago the makers of Unity3d released some really valuable information about casual gaming and general hardware of users that play online games.  It was an interesting report and very beneficial to developers on the Unity platform and others.  We wish other plugin makers would do the same in such a thorough method.

Unity 3d creators listened to the market and have now posted updated numbers and information as well as a page that quarterly stats will be updated. Check the new, quarterly, hardware of the casual gamer stats.

I would have seen this earlier but I have been deep in a Unity 3d project myself :).  I am a big fan of all web based gaming platforms and Unity is almost a dream come true for 3d web gaming.  For the company to be this open that is a very good sign.

What can you do with Unity3D?  Here is a list of games made with Unity3D on the web.  The one great thing about this platform is that is was made for gaming specifically from the start.  Simulations and game development with Unity3D is very fun and productive. I still love Flash, Director etc but Unity3D development is now very much in my rotation.

Games made with Unity3D:

Hancock Movie Games

Tennis Stars Cup

Duckateers

Temploe (ninjas attack you)

RC Laser Warrior

Urban Race Star

FlashBang studios

TraceON

EPIC Tower Defense

InvinciCar

Besmashed (multi)

Global Conflicts

Phoenix Final

Doom Siege

Mario Galaxy like run (third one down)

Zombie Drive

Pocket Piglets

ChickenDemo

Castle Conquest

More Creative Flash AS3 Papervision 3D Games

Here are some really stylish and well done uses of Papervision 3D to make fun games. The people at Bloc recently launched Meta4orce, a unique interactive sci-fi TV show site with some great and numerous uses of papervision 3d.  My favorite is the tron like style and the tower defense game called shock to the system.

Hardware of the Casual Gamer

Making great games, applications and tools using flash, silverlight or other tools that are emerging such as Unity3D takes great style, effort and knowing your target. We need to know what the end-user machine has at hand.  The Unity 3d guys put together a great post on the capabilities of casual gaming machines. With all the talk about flash 3d, unity3d and silverlight what level are you targeting and what group of people can actually PLAY your games as you envision.

Pretty much everyone knows Valve’s hardware survey – it’s a very valuable resource that shows what hardware the typical “hardcore PC gamer” has (that is, gamers that play Valve’s games).

However, the “casual gamer”, which is what Unity games are mostly targeted at, probably has slightly different hardware. “Slightly” being a very relative term of course.

Lo and behold – we have a glimpse into that data.

How? First time the Unity Web Player is installed, it submits anonymous hardware details (details in the EULA). This happens only once, and contains no personally identifiable information. It’s much like visitor statistics trackers on the websites that gather your OS, browser information and whatnot.

Remember, all this data is from people who installed Unity Web Player (most likely because they wanted to play some Unity content on the web). Hardware of standalone game players might be different, and hardware of your game’s players might be different as well. The data set is well over a million samples at the moment.

Check out the full stats here.

The most interesting stats to me:

OS Platforms

Windows 96.8%

Mac OS X 3.2%

CPU Core count overall

1 54.7%

2 44.1%

4 1.1%

8 .1%

Wow this one is surprising, but with the type of gamer that will play and download a quality new plugin to get to a game, maybe not.  They need to have the latest and greatest.  Multi-core processors have been selling for about 2-3 years so this is a continuing trend that will make Flash 3d and even plugins like Unity 3d better over the short term.

Also when you check it over at Unity Blog note the top cards, it is a bit painful if you are a casual gamer developer.  Not a decent card in the top 10-15. But that is changing rapidly over the next 1-2 years in this regard. But this also vyes well for flash based games that rely on dual core software rendered results right now as a decent constraint for developers to keep content painfully accessible to all states of machinery out there.

I wonder if this information is available on the flash player and public? This is specific to the Unity 3D plugin that is also a bit of a different market that is willing to install a plugin for better experiences.  With Flash it is usually preinstalled or auto updated for a casual user and might be different as Flash has a 98% penetration rate.  Or for that matter the Director users which would be more gaming focused which amout ot about 40% of internet users.  But as with the case of Unity it is specific to games right now and a small penetration rate, Flash is also apps, ads, tools, demos, interactives in addition to games.  Having this information on Flash or Director would be nice.

AS3 Flash 3D Engine Alternativa Platform Drops A Nuke – Isometric and FPS

This will blow you away. Found first via mrdoob (with quantum rss reading capability, before the message is concieved mrdoob is there).

Alternativa Platform, previously Alternativa Game, launched their Alternativa Platform milestone 1 and really one demo would have been enough but there are some great demos there that literally put them what appears a couple laps up on the 3d FPS style engine in Flash.

The engine is highly optimized and smooth, heavy on the processor, but using the ‘t’ key you can see some nice revealing triangle rendering. Also, playing with the field of view adds for some nice game effects. (try jumping on the fans in the half-life like room in the first demo)

Check the textures

Here is what is to come from the platform:

Congrats to the Russian based Alternativa Platform, the world is watching.
