Methods

addComponent<T extends Component>(int entity, T component) → void
Adds a component to the entity.
inherited
addComponents<T extends Component>(int entity, List<T> components) → void
Adds components to the entity.
inherited
addEntity(int entity) → void
Adds a int entity to this world.
inherited
addManager(Manager manager) → void
Add a manager into this world. It can be retrieved later. World will notify this manager of changes to entity.
inherited
addSystem(EntitySystem system, {bool passive = false, int group = 0}) → void
Adds a system to this world that will be processed by process(). If passive is set to true the system will not be processed by the world. If a group is set, this system will only be processed when calling process() with the same group.
override
createEntity<T extends Component>([List<T> components = const []]) → int
Create and return a new or reused int instance, optionally with components.
inherited
deleteAllEntities() → void
Removes all entities from the world.
inherited
deleteEntity(int entity) → void
Mark an entity for deletion from the world. Will be deleted after the current system finished running.
inherited
deleteManager(Manager manager) → void
Deletes the manager from this world.
inherited
deleteSystem(EntitySystem system) → void
Removed the specified system from the world.
inherited
destroy() → void
Destroy the World by destroying all EntitySystems and Managers.
inherited
frame([int group = 0]) → int
Returns the current frame/how often the systems in group have been processed.
inherited
getComponents(int entity) → List<Component>
Get all components belonging to this entity.
inherited
getManager<T extends Manager>() → T
Returns a Manager of the specified type T.
inherited
getPerformanceStats() → List<PerformanceStats>
Returns the PerformanceStats for every system and and the PerformanceStats for changes to ints that require updates to other EntitySystems and Managers.
getSystem<T extends EntitySystem>() → T
Retrieve a system for specified system type.
inherited
initialize() → void
Makes sure all managers systems are initialized in the order they were added.
inherited
moveComponent<T extends Component>(int srcEntity, int dstEntity) → void
Moves a Component of type T from the srcEntity to the dstEntity. if the srcEntity does not have the Component of type T nothing will happen.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
process([int group = 0]) → void
Processes all changes to entities and executes all non-passive systems.
override
removeComponent<T extends Component>(int entity) → void
Removes a Component of type T from the entity.
inherited
time([int group = 0]) → double
Returns the time that has elapsed for the systems in the group since the game has started (sum of all deltas).
inherited
toString() → String
A string representation of this object.
