ULevelSequence and ALevelSequenceActor failed to compiled?

I simply defined the following variables in the .h file, and only quoted the source file in .cpp.
But this can’t compile successfully, I wanna how to fix it? Thanks for your help.:slight_smile:

UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = “Communication”)
class ULevelSequence* AnimSeq;
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = “Communication”)
class ALevelSequenceActor* AnimSeqActor;

#include “Runtime/LevelSequence/Public/LevelSequence.h”
#include “Runtime/LevelSequence/Public/LevelSequenceActor.h”
