Roku Developer Program

So, I'm trying out the Row List component. Running this code doesn't throw any errors, but it immediately restarts the roku box.

Here's the xml:

<?xml version="1.0" encoding="utf-8" ?> 
<component name="carouselScene" extends="Scene" >

    <script type="text/brightscript" uri="pkg:/components/scripts/CarouselSceneScript.brs" />

    <children>

        <RowList
            id="contentRow1"
            itemComponentName="Poster"
            translation="[0, 50]" />


    </children>
</component>

And here's the script:

Sub init()
    ?"CarouselSceneScript:init()"
    m.contentRow1 = m.top.findNode("contentRow1")
    configureRowList()
    m.top.setFocus(true)
end Sub

Sub configureRowList()

    content = createObject("RoSGNode", "ContentNode")
    content.TITLE = "Test Row"

    for x = 1 to 21
        thisCon = content.createChild("ContentNode")
        thisCon.HDPOSTERURL = "pkg:/locale/default/images/book-covers-" + x.ToStr() + ".jpg"
    end for

    m.contentRow1.rowItemSize = [[335,463]]
    m.contentRow1.content = content

end Sub

I've put stops in and stepped through it. It doesn't throw errors and crashes the box when it goes to draw.

@Roku - do you guys have a significant number of developers in North California?

If so, organize a meetup to present this new paradigm. Otherwise, make it a webinar/web conference.

Free bonus: record that presentation and make it available for future play.

could you provide code for a working sample of a button node?

And maybe a simple RowList?

[RokuRobB]

Here is a button sample. You basically need to define an observer for the buttonSelected field:

SimpleButtonScene.xml
<?xml version="1.0" encoding="utf-8" ?>

<component name="SimpleButtonScene" extends="Scene" >

<script type="text/brightscript" uri="pkg:/components/SimpleButtonScene.brs" />

<children>
<Button id="button" text="Press Me!" />
</children>

</component>

SimpleButtonScene.brs
function init()
m.button = m.top.findNode("button")
m.button.ObserveField("buttonSelected", "onButtonSelected")
m.button.SetFocus(true)
end function

function onButtonSelected() as void
print "Button Pressed"
end function

A RowList sample is coming soon.

Couple of questions:

1. For which players will the scenic graph API/firmware be made publicly available? All model# > 2200 or ...


2. Can you point some notable examples of channels that already use scenical graphing, so we can see its goodness? (e.g. if you ask Marmalade for examples of games made with their SDK, they'd tell you Plants v Zombies, Cut the Rope, some of the Angry Birdses and Tetrises...)

* Should be all players other than 3.1 legacy devices.
* Not really, but you can get a good idea from the Roku Home Screen and mGo channels.

We just released the beta, for trailblazers to get started blazing trails.

When is the planned general availability of the Scene Graph firmware?
I'd like to use it, but don't want to have to wait too long for releasing our channel due to lack of GA support.

We are not disclosing the launch date at this time. This Beta is to get feedback on technical issues and improvements that could make the scene graph a better experience for developers when it is launched.

Is this where we should reports bugs in the v7.0 firmware or is there somewhere else to do that?
