Roku HD2000 manual Roku Objects, Examples

9. If you want the script to autorun upon boot, rename it “autorun.bas”

Roku Objects

As well as the BrightScript language itself, BrightSign relies upon a library of “Roku Objects” to expose the hardware to the scripting language. Each Roku Object provides access to certain capabilities. For example, there is a roVideoPlayer object and a roTouchScreen object. To create an object in a script, the CreateObject() function is used.

Refer to the following two manuals when writing scripts:

•Roku BrightScript Reference -- this describes the actual scripting language

•Roku Object Reference -- this describes the Roku Objects, such as “roVideoPlayer”

Examples

A good way to learn BrightScript is to look at or modify existing scripts. You can find links to example scripts at www.rokulabs.com/brightsign. The BrightSign Demo “autorun.bas” is an example of a more sophisticated script.

You can also test BrightScript commands using the shell. Here is an example:

Welcome to the Roku Shell version 1.1.28 Release

Type '?' for help or 'help <command>' for help on <command>.

Roku> script

BrightScript Micro Debugger.

Enter any BrightScript statement, debug commands, or HELP.

BrightScript> print "hello" hello

BrightScript> ? "hello" hello

BrightScript> ?5+6 11

BrightScript> ?type(5) rotINT32

BrightScript> if 1=1 then print"1 does equal 1!" else print "strange!" 1 does equal 1!

BrightScript> ?right("abcdef",3) def

BrightScript> exit Roku>
