Detailed Description

Behavior element behavior adding a renderable canvas view.

This behavior is useful for models with a complex dynamic texture where the content of the texture is provided by one or more Canvas resources. Multiple other behaviors can add their content to the canvas renderable to separate logic for reuse. A convenient base class to use is ECBehaviorRenderableCanvasBase.

To use this behavior add an ECBehaviorDynamicSkin to the element class before adding this behavior. Create ECBehaviorRenderableCanvas behavior and set the dynamic skin and canvas background color or image. The background color empty by default so make sure to set an appropriate background. Now you can add other behaviors targeting the ECBehaviorRenderableCanvas to add Canvas resources to.

If the background is not set the behaviors using this canvas have to make sure they cover the entire background to avoid artifacts. Background CanvasPaint or CanvasImage have order 0 respective 1 if both are used. Both canvas can be used for example if the image has transparency.

The canvas is created with a default size of 512x512 . You can change the size using the element property to fit the texture requirements.

Multiple ECBehaviorRenderableCanvas instances can be added to affect individual dynamic skin textures. The example below uses one component with one dynamic skin to two individual renderables named "content1" and "content2" each allowing to be individiaully filled with content by different behaviors.

class MyElement extends BehaviorElementClass
public func new()
ECBehaviorComponent.new(this)
ECBehaviorDynamicSkin.new(this)
ECBehaviorCanvas.new(this)
ECBehaviorCanvas.new(this, "canvas2")
var ECBehaviorRenderableCanvas behavior = ECBehaviorRenderableCanvas.new(this)
behavior.getRenderable().setValue("content1")
behavior = ECBehaviorRenderableCanvas.new(this, "renderableCanvas2")
behavior.setBackgroundColor(Color.blue)
behavior.getRenderable().setValue("intensity2")
end
end
ECBehaviorRenderableCanvas new(BehaviorElementClass eclass, ECBehaviorDynamicSkin dynamicSkin)
Create behavior element class.
ECPString getRenderable()
Name of renderable to create or empty string if not used.

Element class properties have the prefix "renderableCanvas{(id)}.".

This behavior does not require the element class to be persistable (setPersistable).
