Roku Developer Program

[DavidAW]

Hi all,
I am just starting looking into Roku development. I looked at the sample video player, and then the new "Simple Grid And Video" example from the SceneGraph example here:

https://blog.roku.com/developer/2016/03 ... /#more-964

When I download this sample and run it though it does not work. It fails as shown below:

BrightScript Debugger> next
022:     scene.gridContent = ParseXMLContent(list)

BrightScript Debugger> s
022:     scene.gridContent = ParseXMLContent(list)

Current Function:
014:              ContentList : oneRow
015:          }
016:          {
017:              Title:"Second row"
018:              ContentList : oneRow
019:          }
020:      ]
021:      
022:*     scene.gridContent = ParseXMLContent(list)
023:  
024:      while true
025:          msg = wait(0, port)
026:          print "------------------"

The problem seems to be that the scene isn't valid.

screen = CreateObject("roSGScreen")
scene = screen.CreateScene("HomeScene")

The "HomeScene" is defined in a separate file. Maybe it needs to be imported or something? I am new to BrightScript.

Thanks for any help. This SceneGraph model seems cleaner than writing the whole app in one file.

If you are using Eclipse IDE, make sure that you have selected the components, images and source folders on export. Sometimes they don't get selected properly and the app crashes because the files were not included in the package.
