Add->Actor To Sequencer as C++ code

What is the C++ code for the menu action Sequencer->Add->Actor To Sequencer?

I tried

ActorGUID = scene->AddPossessable(ActorName,actclass);

to add an actor which exists in the level.
But this gives me a red label of the actor name (=ID) on the track, saying:
“The object bound to this track is missing”

2

Does this error appers when actor exists?

You’re pretty close. You also need to get the movie scene sequence and bind the possessable, in your case something like this:

MovieSceneSequence->BindPossessableObject(ActorGUID, *Actor);

Seems not to be enough, its still red, when I BindPossessableObject to my LevelSequence.
Maybe its a better idea, to use FLevelSequenceEditorToolkit::AddActorsToSequencer(AActor*const* InActors, int32 NumActors).
How would I create or get this toolkit?

You dont create it, you use once that are open. You can access it via

FLevelSequenceEditorToolkit::OpenToolkits

or

IterateOpenToolkits(TFunctionRef<bool(FLevelSequenceEditorToolkit&)> Iter);

Note that this is editor code and so this will work only in editor and you need to make you module editor only or put code using this APIs under

#if WITH_EDITOR
//stuff here
#endif

or else you will have errors in packageing

Thanks, it’s Editor-only code, so no problem. :slight_smile:

I tried your suggestion and added “LevelSequenceEditor” to my module names but get a linker error:
Error: Couldn’t find parent type for ‘AnimationConduitGraphSchema’ named ‘UEdGraphSchema_K2’ in current module or any other module parsed so far

‘UEdGraphSchema_K2’ is in “BlueprintGraph”, so I added this module, too.
But this didn’t help, same error.

Which modules are needed to solve this error?

7

can you show your code where you refrence that?

I want to add an actor to the sequencer in C++.
Don’t understand, why every simple step which is already implemented in an editor menu or blueprint is so hard to do in C++.
I gave up here, thanks for helping @anonymous_user_f5a50610.

I did it like this:

ULevelSequence *LevelSequence; 
AActor *Actor;
FGuid Guid;
Guid = LevelSequence->MovieScene->AddPossessable(Actor->GetActorLabel(), Actor->GetClass());
LevelSequence->BindPossessableObject(Guid, *Actor, Actor->());

Thanks, that’s what I did. I tried again and it now is actually working. Don’t know what the problem was, probably sth to do with the actor’s label.

This is a funny signature problem for someone who just want to get a toolkit.

static void IterateOpenToolkits(TFunctionRef<bool(FLevelSequenceEditorToolkit&)> Iter);
