Detailed Description
Scene which contains a set number of SceneEntities. The Scene is what contains all of the elements to be drawn at a time. The SceneEntities are stored in a SceneGraph with a SceneNode as the root node, where transformations are composed to find the child transformations. Multiple scenes may be created (and probably should), but a DrawHandler can only have one scene set at a time.
Constructor & Destructor Documentation
psastras::engine::graphics::Scene::Scene |

) |
[inline] |
The scene constructor. Currently doesn't do anything. A scene must be created by adding items to the root node.
Member Function Documentation
void psastras::engine::graphics::Scene::addEntity |
( |
SceneEntity |
e |
) |
[inline] |
Adds an entity to the scene. When adding entities, touch and physics handlers should be already applied, otherwise they may not necessarily have any effect.
- Parameters:
-
void psastras::engine::graphics::Scene::draw |
( |
final Canvas |
c, |
|
|
final Engine |
e, |
|
|
final Viewport |
v | |
|
) |
| | [inline] |
Responsible for calling the draw methods of all the entities contained within the scene that should appear on the screen. If the root node is null, this returns, doing nothing. Otherwise, it checks if the scene is dirty (objects have been added or removed since the last draw), and if it is dirty, it prepares the scene for drawing by zsorting all of the scene entities, and culling objects outside of the viewport. Finally, it draws all of the SceneEntities.
- Parameters:
-
| c | The application drawing canvas. |
| e | The Engine instance. |
| v | The current viewport. |
