All Actions in the project can be accessed and modified via scripting. Use the GetAction function to get a reference to the action:

  • BaseAction GetAction(string actionName)

Note: It's possible for a project to contain multiple actions that have the same name. If that is the case for your project, the first Action created with a name is returned. Make sure to use unique names when accessing actions through scripting.

Every Action type has these generic properties:

Action type

Description

string Name

The title of the action.

string Description

By default this is the type of action (for example, "Key", "Chroma", "Image" etc.). When assigned to a TransformationAction and visible on the SET view, this field is used as a tooltip when the mouse hovers over the element.

int ExecutionDelay

Expressed in milliseconds, minimum delay is 0 (default), maximum delay is 10000 (10 seconds).

Every Action type has these generic methods:

  • void Execute(): Executes the action.

  • void Preview(): Executes the action on the preview channel.

  • void QueryState(): Queries the current state of the action from the Editing Engine. For example, if the action is a transformation action, it retrieves the current transformation from the editing engine's scene tree and updates the UI accordingly.

The example below shows how to set the alpha value to 75% of an Alpha Action called AlphaText and execute the action from scripting:

Sample

var alphaAction = GetAction("AlphaText");
alphaAction.Alpha = 75.0;
alphaAction.Execute();
