Detailed Description

Use a Property Target Interpolator when you want to dynamically set the target value of a property and want to interpolate the current value to the target value over time.

With a Property Target Interpolator you can automatically animate the change of a property value to achieve a smooth transition. Without a Property Target Interpolator Kanzi immediately applies a new value to a property. For example, when you use the Object::setProperty() function, Kanzi immediately applies a new value.

Use the InterpolatedPropertyTypeProperty to set the property type that you want the Property Target Interpolator to interpolate in the node to which you attach the Property Target Interpolator.

Property Target Interpolator emulates the behavior of a spring-damper system which never overshoots. Use these properties to control the behavior of the interpolation:

  • AccelerationProperty sets the force with which the spring moves the object. The larger the value of the Acceleration property is, the faster the property reaches its new value.
  • DragProperty sets the damping coefficient. The larger the value of the Drag property is, the lower is the maximum interpolation speed.

The Property Target Interpolator applies the InterpolatedPropertyTypeProperty, AccelerationProperty, and DragProperty properties only when you attach the Property Target Interpolator to a node. You cannot change the target property or interpolation behavior of the Property Target Interpolator by setting the values of these properties after the Property Target Interpolator is already attached to a node.

Examples

To create a Property Target Interpolator and set its target property and interpolation settings:

// Create property target interpolator.
// Set type name of property which should be interpolated on the node where interpolator will be attached.
interpolator->setInterpolatedPropertyType(Node2D::OpacityProperty.getName());
// Adjust interpolation settings.
interpolator->setAcceleration(2.0f);
interpolator->setDrag(1.0f);

To attach a Property Target Interpolator to a node:

node->addNodeComponent(interpolator);

Member Data Documentation

MessageType<CompletedMessageArguments> kanzi::PropertyTargetInterpolator::CompletedMessage
static

The node to which the Property Target Interpolator is attached sends the Completed message when the Property Target Interpolator completes the interpolation.

PropertyType<string> kanzi::PropertyTargetInterpolator::InterpolatedPropertyTypeProperty
static

Sets the property type that you want interpolate with a Property Target Interpolator in the node to which you attach the Property Target Interpolator.

The default value of this property is "".

setInterpolatedPropertyType(), getInterpolatedPropertyType(), InterpolatedPropertyFieldProperty
PropertyType<KzuPropertyBinaryTargetAttribute> kanzi::PropertyTargetInterpolator::InterpolatedPropertyFieldProperty
static

Sets the property field of the property type that you want to interpolate with a Property Target Interpolator.

The default value of this property is "".

setInterpolatedPropertyField(), getInterpolatedPropertyField(), InterpolatedPropertyTypeProperty
PropertyType<float> kanzi::PropertyTargetInterpolator::AccelerationProperty
static

Sets the speed at which the interpolated property reaches its new value.

Property Target Interpolator emulates the behavior of a spring-damper system which never overshoots. The Acceleration property sets the force with which the spring moves the object. The larger the value of the Acceleration property is, the faster the property reaches its new value. The default value is 1.0f.

PropertyType<float> kanzi::PropertyTargetInterpolator::DragProperty
static

Controls the maximum interpolation speed.

Property Target Interpolator emulates the behavior of a spring-damper system which never overshoots. The Drag property sets the damping coefficient. The larger the value of the Drag property is, the lower is the maximum interpolation speed. The default value is 0.0f.
