Detailed Description

Configure transitions between states.

When you configure transitions between states you can set the start and end states of a transition, transition duration, how you want Kanzi to handle interruptions of a transition, the direction to which the transition applies, and manage transition animations.

Examples

To configure a state transition:

        public void Execute(PluginCommandParameter parameter)
        {
            // Get the State Managers library which stores state managers used in a Kanzi Studio project.
            var stateManagerLibrary = studio.ActiveProject.StateManagerLibrary;
            // Create a state manager named MyStateManager in the State Managers library.
            var myStateManager = studio.ActiveProject.CreateProjectItem<StateManager>(
                stateManagerLibrary.GenerateUniqueChildName("MyStateManager"), stateManagerLibrary);
            // Create a state group named MyStateGroup in the MyStateManager state manager.
            var myStateGroup = studio.ActiveProject.CreateProjectItem<StateGroup>(
                myStateManager.GenerateUniqueChildName("MyStateGroup"),
                myStateManager);
 
            // Create five states in the MyStateGroup state group
            var myStates = new List<State>();
            for (int i = 0; i <= 4; i++)
            {
                myStates.Add(studio.ActiveProject.CreateProjectItem<State>(
                    myStateGroup.GenerateUniqueChildName("MyState" + i),
                    myStateGroup));
            }
 
            // Create a transition between the first and second state in the MyStateGroup state group.
            var stateTransition = myStateGroup.CreateTransition(myStates[0], myStates[1]);
 
            // Configure the transition between states you just created.
            // Set the state from which the transition starts to the third state.
            stateTransition.StartState = myStates[2];
            // Set the state with which the transition ends to the fifth state.
            stateTransition.EndState = myStates[4];
            // Set the transition to last 1500 milliseconds.
            stateTransition.Duration = 1500;
            // Wait 1000 milliseconds before starting the transition.
            stateTransition.StartTime = 1000;
            // When an interruption occurs use the entire time set in the Duration to transition to the state.
            stateTransition.TimePolicy = InterruptTimePolicy.COMPLETED_IF_INTERRUPTED;
            // Make the transition only from the start state to the end state.
            stateTransition.Direction = DirectionType.UNIDIRECTIONAL;
            // Use the Smooth Step easing function for the transition.
            stateTransition.AnimationType = StateTransitionAnimationType.SMOOTH_STEP;
        }

ClearAnimations()

void ClearAnimations

(

)

Deletes all animations in a state transition.

DeleteAnimation

CreateAnimation()

TransitionAnimation CreateAnimation	(	string	targetPath,
		Property	property )

Creates an animation in a state transition.

A state transition animation animates the value of a property in a node which the animation targets. Before you can create an animation in a state transition, make sure that both states in the state transition contain a state object which targets the same node and the same property.

Parameters

targetPath	The path to the node to which Kanzi applies the animation.
property	The property to which Kanzi applies the animation.

Returns

The transition animation.

Examples

To create an animation in a state transition:

        public void Execute(PluginCommandParameter parameter)
        {
            // Get the State Managers library which stores state managers used in a Kanzi Studio project.
            var stateManagerLibrary = studio.ActiveProject.StateManagerLibrary;
            // Create a state manager named MyStateManager in the State Managers library.
            var myStateManager = studio.ActiveProject.CreateProjectItem<StateManager>(
                stateManagerLibrary.GenerateUniqueChildName("MyStateManager"), stateManagerLibrary);
            // Create a state group named MyStateGroup in the MyStateManager state manager.
            var myStateGroup = studio.ActiveProject.CreateProjectItem<StateGroup>(
                myStateManager.GenerateUniqueChildName("MyStateGroup"),
                myStateManager);
 
            // Create a state named MyState1 with a state object.
            var myState1 = studio.ActiveProject.CreateProjectItem<State>(myStateGroup.GenerateUniqueChildName("MyState1"), myStateGroup);
            var myStateObjectState1 = studio.ActiveProject.CreateProjectItem<StateObject>(
                myState1.GenerateUniqueChildName("MyStateObject"),
                myState1);
            // Add the Node.Opacity property to the state object. This is the property you animate with the transition animation you create at the end of this snippet.
            // If you do not set a value when you add a property, the property uses its default value. In this case, the value is 1.
            // Leave the value of the property set to the default value. You set a different value in the other state object.
            myStateObjectState1.AddProperty(Properties.NodeOpacity);
 
            // Create a state named MyState2 with a state object.
            var myState2 = studio.ActiveProject.CreateProjectItem<State>(myStateGroup.GenerateUniqueChildName("MyState2"), myStateGroup);
            var myStateObjectState2 = studio.ActiveProject.CreateProjectItem<StateObject>(
                myState2.GenerateUniqueChildName("MyStateObject"),
                myState2);
            // Add the Node.Opacity property to the state object.
            myStateObjectState2.AddProperty(Properties.NodeOpacity);
            // Set the value of the Node.Opacity property to 0.
            myStateObjectState2.Set(Properties.NodeOpacity, 0);
 
            // Create a transition between the MyState1 and MyState2 states in the MyStateGroup state group.
            var stateTransition = myStateGroup.CreateTransition(myState1, myState2);
 
            // Set the transition to last 1500 milliseconds.
            stateTransition.Duration = 1500;
            
            // Wait 2000 milliseconds before starting the transition.
            stateTransition.StartTime = 2000;
 
            // Create an animation which animates the value of the Node.Opacity property in the node to which you attach the state manager.
            stateTransition.CreateAnimation(".", Properties.NodeOpacity);
        }
