The Plugin Message event specifies the action that occurs when a message is received from a custom script plugin that is attached to the presentation. See the Parsers and Plugins tech note for more information on creating custom scripts that send plugin messages.

  • Plugin name: Use the dropdown menu to determine which plugin the event can receive messages from. You can also use the <*> wildcard to match some or all of the plugin message string (i.e. entering "<*>" in this field will match all plugin messages, while entering "mycommand_<any>" will match any plugin message that begins with "mycommand_").
  • Plugin message: Enter the message string that will trigger the event.

Modifying User Variables

You can use the Plugin Message event to modify the values of User Variables. To enable these options, click the Advanced tab:

  • Assign input to variable?: Check this box to assign the content of the plugin message to a User Variable.
    • Input specifies variable: The plugin message string will dynamically specify which User Variable to modify. The plugin message string must be sent in the form of <variable name> : <variable value>.
    • Specify fixed variable: The plugin string will modify a fixed User Variable. Use the dropdown list to choose which User Variable the plugin message will modify. The plugin message string must be sent in the form of <variable value>.

Tip

You can use the Input specifies variable option to modify more than one User Variable with a single event. Use the following string: <variable name> : <variable value> !! <variable name> : <variable value>

  • Assign wildcard to variable?: Check this box to specify the value of a User Variable using the <any> wildcard. Select the User Variable to modify using the dropdown menu to the right. The Plugin Message field must contain the <any> wildcard, either by itself or with additional text (e.g. "message_<any>").

Note

It is possible to check both Assign input to variable and Input specifies variable boxes for more complex functionality. For example, you can use Specify fixed variable to assign the entire message string to one variable, while at the same time using Assign wildcard to variable to assign a subset of that string to another variable.
