UActorComponent::PostApplyToComponent

function Engine Since unknown

#include "Components/ActorComponent.h"

Access: public Specifiers: virtual

Description

Called after ApplyToComponent has run during construction script re-runs. Override to restore state that was cached in GetComponentInstanceData and lost during reconstruction.

Caveats & Gotchas

• Only called when a component survives a RerunConstructionScripts pass — it is not called on initial component creation.
• The counterpart GetComponentInstanceData must also be overridden to cache the data you want to restore here; without it, PostApplyToComponent has nothing to act on.

Restoring cached runtime state after construction script re-run C++

    if (CachedMaterial)
    {
        SetMaterial(0, CachedMaterial);
    }
}
