template<typename Value, typename Property, class PropertyManager>
bn::loop_value_template_action class

Modifies the property of a value by delta from a minimum to a maximum. When the property is equal to the given final state, it goes back to its initial state and vice versa.

Template parameters
Value Value to modify.
Property Property of the value to modify.
PropertyManager Reads and writes the property of the value to modify.

Constructors, destructors, conversion operators

loop_value_template_action(const Value& value, int duration_updates, const Property& final_property) protected
Constructor.
loop_value_template_action(Value&& value, int duration_updates, const Property& final_property) protected
Constructor.

Public functions

void reset()
Resets the property to its initial state.
void update()
Adds or subtracts ((final_property - initial_property) / duration_updates) to the property.
auto duration_updates() const -> int
Returns how much times the action has to be updated before changing the direction of the property delta.

Protected functions

auto value() const -> const Value&
Returns the value to modify.
auto final_property() const -> const Property&
When the property is equal to the returned parameter, it goes back to its initial state and vice versa.

template<typename Value, typename Property, class PropertyManager>
bn::loop_value_template_action<Value, Property, PropertyManager>::loop_value_template_action(const Value& value, int duration_updates, const Property& final_property) protected

Constructor.

Parameters
value Value to copy.
duration_updates How much times the action has to be updated before changing the direction of the property delta.
final_property When the property is equal to this parameter, it goes back to its initial state and vice versa.

template<typename Value, typename Property, class PropertyManager>
bn::loop_value_template_action<Value, Property, PropertyManager>::loop_value_template_action(Value&& value, int duration_updates, const Property& final_property) protected

Constructor.

Parameters
value Value to move.
duration_updates How much times the action has to be updated before changing the direction of the property delta.
final_property When the property is equal to this parameter, it goes back to its initial state and vice versa.

template<typename Value, typename Property, class PropertyManager>
void bn::loop_value_template_action<Value, Property, PropertyManager>::update()

Adds or subtracts ((final_property - initial_property) / duration_updates) to the property.

When the property is equal to final_property, it goes back to its initial state and vice versa.
