GetRTChannels(integer[,boolean] OR handle[,boolean])

Description

The GetRTChannels Lua function returns a table with RT Channel indexes or a table with handles to the RT Channel objects. There are two different types of arguments for this function.

Arguments

• Integer:
  The integer should be the index number for a (sub)fixture.

• Boolean (Optional):

  • True:
    The returned table contains handles for RT Channel objects.
  • False (default):
    The returned table contains integers index values to the RT Channel objects.

- OR -

• Handle:
  The handle should relate to a (sub)fixture object.

• Boolean (Optional):

  • True:
    The returned table contains handles for RT Channel objects.
  • False (default):
    The returned table contains integers index values to the RT Channel objects.

Return

• Table:
  The returned table can be a list of RT Channel indexes or handles to the same RT Channels.

Examples

Example 1

This example prints a list of RT Channel indexes for the first fixture in the selection. It uses an index number as input:

Copy CodeLua
```
return function()

-- Get the index number for the first fixture in the current selection
local fixtureIndex = SelectionFirst()
-- Get the indexes of the RT channels
local rtChannels = GetRTChannels(fixtureIndex, false)
-- Print an error message if returnd table is nil
if rtChannels == nil then
    ErrPrintf("Please select a fixture and try again")
    return
end
-- Print the table content
for key,value in ipairs(rtChannels) do
    Printf("List index number ".. key .." : RTChannel index number = ".. value)
end

end

### Example 2

This example prints a list of RT Channel indexes and attributes for the first fixture in the selection. It uses a handle as the input:
