Detailed Description

Configure node components.

This interface represents a node component host that can have node components. To add functionality to a node, attach node components to that node.

You can create these node components:

• Triggers react to messages or events and apply logic.
• Animation node components (Animation Player, Property Driven Animation Player, and Property Target Interpolator) animate specific properties of the node and its child nodes.
• Input Manipulator node components (Click Manipulator, Multi-Click Manipulator, Key Manipulator, Long-Press Manipulator, and Pan Manipulator) enable and configure gesture and keyboard input recognition for the node.
• Custom node components implement custom functionality that you define in a Kanzi Engine plugin.

This function is the equivalent of calling Project.CreateNodeComponent.

You can find the available node component types in Project.NodeComponentTypeLibrary.

Parameters

name	The name of the node component.
nodeComponentType	The type of the node component.

Returns

The node component you create with this function.

Examples

To create an Animation Player:

        public void Execute(PluginCommandParameter parameter)
        {
            // Get the RootPage node in the Screens/Screen node.
            var rootPage = studio.ActiveProject.GetProjectItem("Screens/Screen").GetChild<Page>("RootPage");
            // Get the Animation Player node component type.
            var animationPlayerType = studio.ActiveProject.NodeComponentTypeLibrary.GetItemByName(NodeComponentTypeNames.AnimationPlayer);
            //  In the RootPage node create an Animation Player named Root Animation Player.
            rootPage.CreateNodeComponent(rootPage.GenerateUniqueChildName("Root Animation Player"), animationPlayerType);
        }

To create and configure a Property Target Interpolator:

        public void Execute(PluginCommandParameter parameter)
        {
            // Get the RootPage node in the Screens/Screen node.
            var rootPage = studio.ActiveProject.GetProjectItem("Screens/Screen").GetChild<Page>("RootPage");
            // Get the Property Target Interpolator node component type.
            var propertyTargetInterpolatorType = studio.ActiveProject.NodeComponentTypeLibrary.GetItemByName(NodeComponentTypeNames.PropertyTargetInterpolator);
            // In the RootPage node create a Property Target Interpolator named Root Property Target Interpolator.
            var propertyTargetInterpolator = rootPage.CreateNodeComponent(
                rootPage.GenerateUniqueChildName("Root Property Target Interpolator"), propertyTargetInterpolatorType);
            // Set the Interpolated Property Type property to Node2D.RenderTransformation
            propertyTargetInterpolator.Set(
                propertyTargetInterpolator.PropertyTypes.PropertyTargetInterpolatorInterpolatedPropertyType,

            propertyTargetInterpolator.Set(
                propertyTargetInterpolator.PropertyTypes.PropertyTargetInterpolatorInterpolatedPropertyField,
                AnimationTargetPropertyAttributeEnum.ROTATION_Z);
            // Set the value of the Acceleration property to 7.
            propertyTargetInterpolator.Set(propertyTargetInterpolator.PropertyTypes.PropertyTargetInterpolatorAcceleration, 7);
            // Set the value of the Drag property to 10.
            propertyTargetInterpolator.Set(propertyTargetInterpolator.PropertyTypes.PropertyTargetInterpolatorDrag, 10);
        }

            // Get the RootPage node in the Screens/Screen node.
            var rootPage = studio.ActiveProject.GetProjectItem("Screens/Screen").GetChild<Page>("RootPage");

            // In the RootPage node create an Image node.
            var image = studio.ActiveProject.CreateProjectItem<Image2D>(rootPage.GenerateUniqueChildName("Image"), rootPage);
            // In the Image node add and enable the Hit Testable property.
            // Kanzi uses hit testing to determine the nodes that receive input.
            image.Set(Properties.NodeHitTestable, true);

            // Get the Multi-Click Manipulator node component type.
            var multiClickManipulatorType = studio.ActiveProject.NodeComponentTypeLibrary.GetItemByName(NodeComponentTypeNames.MultiClickManipulatorComponent);
            // In the Image node create a Multi-Click Manipulator.
            var multiClickManipulator = image.CreateNodeComponent(image.GenerateUniqueChildName("Multi-Click Manipulator"), multiClickManipulatorType);
            // In the Multi-Click Manipulator set the value of the Multi-Click Timeout property to 300 ms.
            multiClickManipulator.Set(multiClickManipulator.PropertyTypes.MultiClickManipulatorComponentTimeout, 300);

            // To create a Multi-Click trigger in the Image node, create a Message Trigger and set the value of the Message Trigger Message Type property to Multi-Click.
