module bpt {

    export class SpritePrefab extends Phaser.Sprite {

        config():any { return "SpritePrefab.json"; }

        constructor(game, x?, y?, key?, frame?) {

            super( game, x, y, key, frame );

            bpt.prefab.configPrefab( this, 'Prefab.json' );

        get animationFrame():any { return 0; }

        set animationFrame( frame:any ) {

            if ( this.animations ) {

                var hack:any = this.animations;

                if ( !hack.loadFrameData(this.game.cache.getFrameData(this.key), frame) ) {

                    this.resetFrame();

                }

            }

        }

    }

    bpt.prefab.Factory.add( "SpritePrefab", SpritePrefab, undefined,
        bpt.prefab.helper_transformed_named_args_to_config );

    export class ImagePrefab extends Phaser.Image {

        config():any { return "ImagePrefab.json"; }

        constructor(game, x?, y?, key?, frame?) {

            super( game, x, y, key, frame );

            bpt.prefab.configPrefab( this, 'Prefab.json' );
            bpt.prefab.configPrefab( this, this.config() );
        }

    }

    bpt.prefab.Factory.add( "ImagePrefab", ImagePrefab, undefined,
        bpt.prefab.helper_transformed_named_args_to_config );

    // ------------------------------------------------------------------------

    // aliases for smaller json files

    bpt.prefab.Factory.addAlias( 'image', 'Phaser.Image' );
    bpt.prefab.Factory.addAlias( 'sprite', 'Phaser.Sprite' );
    bpt.prefab.Factory.addAlias( 'group', 'Phaser.Group' );
    bpt.prefab.Factory.addAlias( 'spriteBatch', 'Phaser.SpriteBatch' );
    bpt.prefab.Factory.addAlias( 'batch', 'Phaser.SpriteBatch' );
    bpt.prefab.Factory.addAlias( 'text', 'Phaser.Text' );
    bpt.prefab.Factory.addAlias( 'tileSprite', 'Phaser.TileSprite' );
    bpt.prefab.Factory.addAlias( 'button', 'Phaser.Button' );
    bpt.prefab.Factory.addAlias( 'emitter', 'Phaser.Particles.Arcade.Emitter' );
}

My prefab.json basically sets the anchor to 0.5 by default

{
    "config" : {
        "anchor":{ "x":0.5, "y":0.5}
    }
}
