Method Details

getViewToRender

public abstract technology.sola.ecs.view.View<V> getViewToRender(technology.sola.ecs.World world)

Returns a View of Entity that need to be rendered via renderEntity(Renderer, V, TransformComponent)

Parameters:

world - the World

Returns:

the view of entities

renderEntity

public abstract void renderEntity(Renderer renderer,
 V viewEntry,
 TransformComponent cameraModifiedEntityTransform)

Called on each Entity to render it. A TransformComponent instance with the camera's transform applied is provided for each entity. If an entity has a LayerComponent it will be rendered to its layer.

Parameters:

renderer - tbe Renderer instance

viewEntry - the ViewEntry containing the Entity to render

cameraModifiedEntityTransform - a TransformComponent with the camera's transform applied to the entity's transform

renderEntity

public void renderEntity(Renderer renderer,
 V viewEntry,
 Matrix3D cameraScaleTransform,
 Matrix3D cameraTranslationTransform)

Called on each Entity to render it. It calculates a TransformComponent instance with the camera's transform applied which is then passed into the renderEntity(Renderer, ViewEntry, TransformComponent) method. If an entity has a LayerComponent it will be rendered to its layer.

Parameters:

renderer - tbe Renderer instance

viewEntry - the ViewEntry containing the Entity to render

cameraScaleTransform - the camera's scale

cameraTranslationTransform - the camera's translation

renderMethod

public void renderMethod(Renderer renderer,
 technology.sola.ecs.World world,
 Matrix3D cameraScaleTransform,
 Matrix3D cameraTranslationTransform)

Description copied from class: SolaGraphicsModule

The specific render method for a graphics module that is called once per frame if active.

Specified by:

renderMethod in class SolaGraphicsModule

Parameters:

renderer - tbe Renderer instance

world - the World instance

cameraScaleTransform - the camera's scale

cameraTranslationTransform - the camera's translation

getTransformForAppliedCamera

protected TransformComponent getTransformForAppliedCamera(TransformComponent entityTransform,
 Matrix3D cameraScaleTransform,
 Matrix3D cameraTranslationTransform)

Utility method for calculating the transform when a camera's transform is applied to another transform.

Parameters:

entityTransform - the Entity's transform

cameraScaleTransform - the camera's scale

cameraTranslationTransform - the camera's translate

Returns:

the resulting TransformComponent
