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
