Detailed Description

Abstract base for all terrain brush components.

Handles creation and cleanup of TerrainSystem brushes, including automatic spline-path support: if an ezSplineComponent exists on the same game object the brush stamps along the spline instead of acting as a single brush. Properties common to 2D and 3D brushes are declared here and inherited by both ezTerrainBrush2DComponent and ezTerrainBrush3DComponent.

Member Function Documentation

◆ DeserializeComponent()

void ezTerrainBrushBaseComponent::DeserializeComponent ( ezWorldReader & inout_stream )

overridevirtual

Override this to load the current state of the component from the given stream.

The active state will be automatically serialized. The 'initialized' state is not serialized, all components will be initialized after creation, even if they were already in an initialized state when they were serialized.

Reimplemented from ezComponent.

Reimplemented in ezTerrainBrush2DComponent, and ezTerrainBrush3DComponent.

◆ FillBrushSpecificProperties()

virtual void ezTerrainBrushBaseComponent::FillBrushSpecificProperties	(	ezTerrainData_Brush &	brush,
		float	fHalfSizeX
	)

protectedpure virtual

Subclass fills: ModifyMode, m_vHalfExtents.y, m_fHalfExtentYTop, m_fHalfExtentZ.

Implemented in ezTerrainBrush2DComponent, and ezTerrainBrush3DComponent.

◆ OnActivated()

void ezTerrainBrushBaseComponent::OnActivated ( )

overridevirtual

This method is called when the component gets activated.

By default a component is active, but it can be created in an inactive state. In such a case OnActivated() is only called once a component is activated. If a component gets switched between active and inactive at runtime, OnActivated() and OnDeactivated() are called accordingly. In contrast Initialize() and Deinitialize() are only ever called once.

See also: OnActivated(), OnDeactivated(), Initialize(), Deinitialize(), OnSimulationStarted()

Reimplemented from ezComponent.

◆ OnDeactivated()

void ezTerrainBrushBaseComponent::OnDeactivated ( )

overridevirtual

This method is called when the component gets deactivated.

Upon destruction, a component that is active first gets deactivated. Therefore OnDeactivated() should be used for typical game code cleanup.

See also: OnActivated(), OnDeactivated(), Initialize(), Deinitialize(), OnSimulationStarted()

Reimplemented from ezComponent.

◆ SerializeComponent()

void ezTerrainBrushBaseComponent::SerializeComponent ( ezWorldWriter & inout_stream ) const

overridevirtual

Override this to save the current state of the component to the given stream.

Reimplemented from ezComponent.

Reimplemented in ezTerrainBrush2DComponent, and ezTerrainBrush3DComponent.
