Elements.pyECSS.ECSSManager.ECSSManager¶

class Elements.pyECSS.ECSSManager.ECSSManager[source]¶

Singleton Manager class to provide factory creation methods for all Entities, Components, Systems, as an alternative way and hide the scenegraph complexity.

__init__()[source]¶: Construct initial data structures for scenegraph elements

Methods

`__init__`()	Construct initial data structures for scenegraph elements
`addComponent`(entity, component)	Adds a component to an Entity in a scenegraph and in the ECSS data structures
`addEntityChild`(entity_parent, entity_child)	Adds a child Enity to a parent one and thus establishes a hierarchy in the underlying scenegraph.
`createEntity`(entity)	Creates an Entity in the underlying scenegraph and adds it in the ECSS data structures.
`createIterator`(entity[, dfs])	Creates and returns a scenegraph traversal node iterator
`createSystem`(system)	Creates a System and adds it in the ECSS data structures
`print`()	pretty print the contents of the ECSS
`traverse_visit`(system, entity[, dfs])	Traverse whole scenegraph by iterating every Entity/Component and calling a specific System on each different element.
`traverse_visit_pre_camera`(camUpdate, camera)	Specifically run a CameraSystem on a Camera Component attached in a scenecegraph, in order to calculate the MR2C root2camera matrix that is an essential part of the local2camera matrix.
