Roku Basic App Creation

Create these files first: main.brs in source folder, LayoutTop.xml, LayoutTop.brs, HomeScene.xml and HomeScene.brs in components.Then add this code in those files: main.brs file:

sub Main() showSGScreen() end sub sub showSGScreen() screen = CreateObject("roSGScreen") m.port = CreateObject("roMessagePort") screen.setMessagePort(m.port) m.scene = screen.CreateScene("HomeScene") screen.show() while(true) msg = wait(0, m.port) msgType = type(msg) if msgType = "roSGScreenEvent" if msg.isScreenClosed() then return end if end while end sub 

LayoutTop.xml:

<?xml version="1.0" encoding="UTF-8"?> <component name="layoutTop" extends="Group" xsi:noNamespaceSchemaLocation="https://devtools.web.roku.com/schema/RokuSceneGraph.xsd"> <script type="text/brightscript" uri="pkg:/components/LayoutTop.brs"/> <children> <Poster id="backgroundPoster" uri="pkg:/images/backgroundTop.jpg" width="1920" height="150" translation="[0, 0]" /> <Poster id="icon" uri="pkg:/images/html5.png" width="128" height="128" translation="[10, 10]" /> </children> </component> 

LayoutTop.brs:

sub init() end sub 

HomeScene.xml:

<?xml version="1.0" encoding="UTF-8"?> <component name = "HomeScene" extends = "Scene" > <script type="text/brightscript" uri="pkg:/components/HomeScene.brs"/> <children> <Poster id="background" uri="pkg:/images/background.jpg" width="1920" height="1080" translation="[0, 0]" /> <Group > <layoutTop translation="[0, 0]" /> </Group> </children> </component> 

HomeScene.brs:

sub init() end sub 

After all this you should get this Screen on your Roku:

That's really not an answerable question without more details. There are different ways of doing that. The simplest way to do just what you described would be with roScreen or roImagecanvas, but each of those choices require more questions. Go through the examples in the Roku SDK. Find things that look interesting and side-load them and look at the source code, you'll find many answers there.
