Member Function Documentation

◆ GetEffectiveScopeHint()

AttributeScopeHint Urho3D::Component::GetEffectiveScopeHint ( ) const

Evaluate effective attribute scope. It is a hint for the Editor to know what is affected by the component addition/removal so it can generate optimal undo/redo actions.

◆ GetID()

unsigned Urho3D::Component::GetID ( ) const
inline

Return ID.

◆ GetNode()

Node* Urho3D::Component::GetNode ( ) const
inline

Return scene node.

◆ HasAuxiliaryData()

virtual bool Urho3D::Component::HasAuxiliaryData ( ) const
inlinevirtual

Return whether the component provides auxiliary data. Only components directly attached to the Scene can have auxiliary data. Auxiliary data is not supported in prefabs.

◆ IsEnabled()

bool Urho3D::Component::IsEnabled ( ) const
inline

Return whether is enabled.

◆ IsEnabledEffective()

bool Urho3D::Component::IsEnabledEffective ( ) const

Return whether is effectively enabled (node is also enabled).

◆ SetEnabled()

void Urho3D::Component::SetEnabled ( bool  enable)

Set enabled/disabled state.

◆ SetID()

void Urho3D::Component::SetID ( unsigned  id)
protected

Set ID. Called by Scene.
