Public Pointers in Unreal c++

Development Programming & Scripting
2

In your header, something like:

public:
    UPROPERTY()
    AMyWeapon *myWeapon;

If you want it to be blueprint accessible, you need to add the proper tags in the UPROPERTY. Then just spawn the actor as you are doing. With this exception, obviously:

// Don't declare a local variable, just assign it to the one in the class.
 myWeapon = GetWorld()->SpawnActor<AMyWeapon>(AMyWeapon::StaticClass(), spawnParams);

You probably should study up on your C++ some more.
