InheritanceBitmapLineRenderer Inheritance BitmapRenderer Inheritance SpriteRendererBase Inheritance flash.display.Sprite

The BitmapLineRenderer draws particles as continuous lines on a Bitmap display object. This is useful for effects like hair and grass.

The BitmapLineRenderer uses the color and alpha of the particle for the color of the current line segment, and uses the scale of the particle for the line width.

The region of the particle system covered by this bitmap object must be defined in the canvas property of the BitmapLineRenderer. Particles outside this region are not drawn.

The BitmapLineRenderer allows the use of BitmapFilters to modify the appearance of the bitmap.

Constructor Detail
BitmapLineRenderer()Constructor
public function BitmapLineRenderer(canvas:Rectangle, smoothing:Boolean = false)

The constructor creates a PixelRenderer. After creation it should be added to the display list of a DisplayObjectContainer to place it on the stage and should be applied to an Emitter using the Emitter's renderer property.

Parameters
canvas:Rectangle
 
smoothing:Boolean (default = false)
Method Detail
drawParticle()method
override protected function drawParticle(particle:Particle2D):void

Used internally to draw the particles.

Parameters

particle:Particle2D

emitterUpdated()method 
override protected function emitterUpdated(ev:EmitterEvent):void

Parameters

ev:EmitterEvent

updateParticles()method 
override protected function updateParticles(ev:Event):void

Parameters

ev:Event
