So i Wanted an actor class to contain another actor , so i have 2 actors one called Aapples and ATree.

Aapples is just a actor generated code by editor.

Atree code here it is :

```
#include "apple.h"
#include "GameFramework/Actor.h"
#include "Tree.generated.h"
UCLASS()
class ATree : public AActor
{
	
public:

	Aapple apples[100]

GENERATED_UCLASS_BODY()
};

```

this generates this error : `Error 1 error : In Tree: Missing ‘\*’ in Expected a pointer type

So i replaced it with pointers to object so later i can initalize them in my code so i changed it to :  
Aapple\* apples[100]

But i dont know how to initalize apples in the code i tried this in Tree.cpp :  
in middle of code:  
apple[0] = new Aapple();

ofcourse there is no constructor with this arguments as all actor constructors are like this :

```
  Aapple::Aapple(const class FPostConstructInitializeProperties& PCIP)
    	: Super(PCIP)
    {
    
    }

```

So i tried this  
apples[0]= new Aapple(PCIP);  
but PCIP is not defiend , so how do i initalize an acotr class ?

apples[0] = GetWorld()-\>SpawnActor(AApple::StaticClass());  
Also, make sue you call that in BeginPlay() and not the constructor, because the world will not be valid in the constructor and crash.
