Safe casts in Unreal Engine
How to safely cast between pointer types.
Actor to Character
Say you have a pointer to an Actor and you’d like to cast this to a Character so you can call your function. Unreal has the Cast function template to do this safely:
ACharacter* Character = Cast<ACharacter>(GetOwner());
if (!Character)
{
return;
}In the above case GetOwner() returns an AActor* which the Cast turns into a nullptr if it’s not an ACharacter (or a child) object.
That is all.
