虚幻引擎 C++ UPaperSprite 数组？

Question

I'm trying to put some sprite in an Array like in my blueprint enter image description here

But it doesn't work and I can't find solution in UE4 documentation Whent I'm trying to do this:

UPROPERTY()
TArray <UPaperSprite*>  spriteArray;

I have some errors like this:

error C2065: 'UPaperSprite'?: Undeclared identifier
error C2059: syntax error?: '>'

Thanks you guys:)

You need to go Project->Properties->IncludeSearchPath->Edit Enter 3 lines as below assume that your unreal engine is in D drive

D:\Program Files\Epic Games\UE_4.24\Engine\Plugins\2D\Paper2D\Source\Paper2D\Classes
D:\Program Files\Epic Games\UE_4.24\Engine\Plugins\2D\Paper2D\Source\Paper2D\Public
D:\Program Files\Epic Games\UE_4.24\Engine\Plugins\2D\Paper2D\Source\Paper2D\

Now you can include #include "PaperSpriteComponent.h"
