Say for example you’re developing a pets game and you have a class
You’ve made a function
ClassType) that returns an array of all the animal instances of a given
Normally in Blueprints if you called this function, you would be returned an array of `AAnimal instances, and before using them you would have to cast them to the animal you expected. Not the end of the world, but kind of annoying
The undocumented meta property
DeterminesOutputType lets you fix that, and
return an array of “pre-cast” instances in Blueprints, removing the need for
casting each element to the expected class type.
