Classes

Name Remarks
FActorModifierRenderStateUpdateExtension This extension tracks specific actors for render state updates, when an update happens it will invoke IAvaRenderStateUpdateExtension function
FActorModifierSceneTreeUpdateExtension This extension tracks specific actors for render state updates, when an update happens it will dirty the modifier it is attached on if filter passes
FActorModifierTransformUpdateExtension This extension tracks specific actors for transform updates, when an update happens it will invoke the IAvaTransformUpdateExtension function
TActorModifierPropertyChangeDispatcher Used to map properties to member functions that will get executed once a property changes
UActorModifierArrangeBaseModifier Abstract base class for modifiers dealing with arrangement and attachment actors on self
UActorModifierAttachmentBaseModifier Abstract base class for all modifiers that deal with attachments
UActorModifierRenderStateUpdateHandler  
UActorModifierSceneTreeUpdateHandler  
UActorModifierTransformShared Singleton class for transform modifiers to share data between each other Used because multiple modifier could be watching/updating an actor We want to save the state of that actor once before any modifier changes it and restore it when no other modifier is watching it
UActorModifierTransformUpdateHandler  
UActorModifierVisibilityShared Singleton class for visibility modifiers to share data between each other Used because multiple modifier could be watching/updating an actor We want to save the state of that actor once before any modifier changes it and restore it when no other modifier is watching it
