Entity class
A container that holds components essentially.
Constructors
- Entity(String guid, EntitySystem system)
Properties
-
components
→ BehaviorSubject<
Map< Type, Component> > -
final
- guid → String
-
final
- hashCode → int
-
The hash code for this object.
no setterinherited
-
isDestroyed
→ BehaviorSubject<
bool> -
Used internally for verifying Entity has not been destroyed before
mutating any values.
final
-
props
→ List<
Object> -
The list of properties that will be used to determine whether
two instances are equal.
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- stringify → bool?
-
If set to
true, the toString method will be overridden to output this instance's props.no setterinherited - system → EntitySystem
-
The system where this entity is contained.

Methods
-
componentDiff(
Entity e) → Set< Type> - Compares the component list between entities and returns a list of types of components that "a" has that "b" does not.
-
destroy(
) → void - Destroy an entity which will lead to following steps:
-
get<
T extends Component> () → T - Returns a matching component from type T.
-
has<
T extends Component> () → bool - If entity has a component of type T
-
hasComponent(
Type type) → bool - Checks if entity has a component of the type of the given object.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
remove<
T extends Component> () → void - For cascade
-
set(
Component component) → void - For cascade
-
toJson(
) → Map< String, dynamic> -
toString(
) → String -
A string representation of this object.

Component component) → Entity - Adds component to the entity.
-
operator -(
Type t) → Entity - Removes component from the entity.
