impl EntityAttributeInstance

pub fn new(attribute: EntityAttribute) -> Self

Creates a new instance of an Entity Attribute.

pub fn new_with_value(attribute: EntityAttribute, base_value: f64) -> Self

Creates a new instance of an Entity Attribute with a value.

pub fn attribute(&self) -> EntityAttribute

Gets the attribute.

pub fn base_value(&self) -> f64

Gets the base value of the attribute.

pub fn compute_value(&self) -> f64

Gets the computed value of the attribute.

pub fn with_add_modifier(&mut self, uuid: Uuid, modifier: f64) -> &mut Self

Sets an add modifier.

If the modifier already exists, it will be overwritten.

Returns a mutable reference to self.

pub fn with_multiply_base_modifier( &mut self, uuid: Uuid, modifier: f64, ) -> &mut Self

Sets a multiply base modifier.

If the modifier already exists, it will be overwritten.

Returns a mutable reference to self.

pub fn with_multiply_total_modifier( &mut self, uuid: Uuid, modifier: f64, ) -> &mut Self

Sets a multiply total modifier.

If the modifier already exists, it will be overwritten.

Returns a mutable reference to self.

pub fn with_modifier( &mut self, uuid: Uuid, modifier: f64, operation: EntityAttributeOperation, ) -> &mut Self

Sets a value modifier based on the operation.

If the modifier already exists, it will be overwritten.

Returns a mutable reference to self.

pub fn remove_modifier(&mut self, uuid: Uuid)

Removes a modifier.

pub fn clear_modifiers(&mut self)

Clears all modifiers.

pub fn has_modifier(&self, uuid: Uuid) -> bool

Checks if a modifier exists.

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
