Multidirectional Tile Scroller

MultidirectionalTileScroller is a Starling framework extension that easily facilitates multidirectional scrolling of a tiled texture.

After instantiating the object with a width, height and texture, scrolling can be achieved simply by supplying speed and angle arguments prior to or during a play() method call.

//Instantiate the object with a width, height and texture (and optional texture scaling)
m_Background = new MultidirectionalTileScroller(
                                               stage.stageWidth,
                                               stage.stageHeight,
                                               m_Texture,
                                               1.0,
                                               1.0
                                               );
//Add it to the stage
addChild(m_Background);
 
//Assign speed and angle values prior to calling play().
m_Background.speed = 2;
m_Background.angle = -42;
m_Background.play();
 
//Optionally pass new speed and angle arguments to the Start function.
m_Background.start(0.25, 180);
 
//Stop Scrolling by calling stop().
m_Background.stop();
 
//To maintain the previously set speed and angle properties, simply call play() again.
m_Background.play();

• angle:Number

• isAnimating:Boolean [read only]

• speed:Number

• MultidirectionalTileScroller(width:uint, height:uint, texture:Texture, textureScaleX:Number = 1.0, textureScaleY:Number = 1.0)

• dispose():void

• play(speed:Number = NaN, angle:Number = NaN):void

• setSize(width:uint, height:uint):void

• setTexture(texture:Texture, textureScaleX:Number = 1.0, textureScaleY:Number = 1.0):void

• stop():void

• The maximum speed (pixels per frame) is capped at the texture's smallest width or height
• Angle values are in degrees (not radians)
• Default speed value is 0.0
• Default angle value is 0.0

• 2015/05/03: Replaced legacy QuadBatch with MeshBatch to support Starling v2.x.
• 2013/12/07: Added public setTexture(~) and setSize(~) functions.
• 2013/11/09: Changed m_Canvas from a Sprite to a QuadBatch.
• 2013/11/08: Added public dispose() function.
• 2013/11/07: First public version.
