How do i dynamically change a variable in the editor

[ImagineX12]

So i have a variable in cpp which i edit in blue print

how would i make it so that when i change the pick up mesh in the editor the materials array dynamically updates to the meshes default materials like how the static mesh component works

Override PostEditChangeProperty().

AActor::PostEditChangeProperty | Unreal Engine 5.2 Documentation

Example for changing a class property enum called “_type” in a class called ConfigurableActor.

#if WITH_EDITOR

/**
* Called when a property on this object has been modified externally.
* NOTE: requires #if WITH_EDITOR or development/shipping binaries will not compile.
*/
virtual void PostEditChangeProperty(struct FPropertyChangedEvent& propertyChangedEvent) override;

#endif

#if WITH_EDITOR
void AConfigurableActor::PostEditChangeProperty(FPropertyChangedEvent& propertyChangedEvent)
{
	// get the property name from the property changed event
	const FName changedPropertyName = (propertyChangedEvent.Property ? propertyChangedEvent.MemberProperty->GetFName() : NAME_None);

       // "type" property changed
	if (changedPropertyName == GET_MEMBER_NAME_CHECKED(AConfigurableActor, _type))
	{
		ConfigureComponents(); // custom function where actor is configured
	}

	Super::PostEditChangeProperty(propertyChangedEvent);
}

#endif
