Selection Commands
A selection command is a type of CueScript command that is used to refer to objects in the system.
Selection commands can be used in conjunction with action commands to perform actions, or selection
commands can be used by themselves to query an object’s value.
Selecting Objects To Perform Actions
As CueScript is being interpreted by the system, selection commands are used in conjunction with action
commands to get things done. First, one or more objects are
selected by using a selection command, and
then one or more action commands are used to operate on those selected objects.
For instance, the following CueScript does two things. First, it selects a button. Second, it performs the
On
action.
Button 1 On
Note that the On action turns “on” the currently selected objects, which in this case happens to be Button 1.
The next CueScript selects playback number 3 with a selection command, then the action command
At 75
sets the playback’s submaster to 75%.
Playback 3 At 75
More than one action can be performed on a selected object. The following example shows the selection
command
Channel 1
followed by four action commands:
Time 0
,
At 100
,
Time 5
, and
At 0
. In other
words, Channel 1 is selected, then the fade time is set to zero, then Channel 1’s value is set to 100%, then
the fade time is set to 5 seconds, then Channel 1’s value is set to 0%.
Channel 1 Time 0 At 100 Time 5 At 0
Stringing multiple actions together that refer to the same selected object is a powerful way to express
compound actions that you want to apply to one or more objects.
Referring To Objects To Determine Their Value
Another powerful way to use selection commands is to refer to one or more object to retrieve their value.
