Unreal Engine 4.x Scripting with C++ Cookbook - Second Edition

How to do it...

Say we have a UCLASS() macro as follows:

UCLASS() 
class MYPROJECT_API AWarrior : public AActor 
{ 
  //TArray< FSoundEffect > Greets; // Incorrect 
  UPROPERTY() TArray< FSoundEffect > Greets; // Correct 
}; 

You'd have to list the TArray member as UPROPERTY() for it to be properly reference-counted. If you don't do so, you'll get an unexpected memory error-type bug sitting about in the code.
