Fast forward: I have a car and it has an object reference to a spline path actor. It gets a vector of the path’s first point.
The problem is: the object reference can be empty. Right now, the car always tries to get the vector, so in case there’s no referenced path, errors begin to appear (obviously).
I struggle to find the condition to test its emptiness. Somewhere I found “Is valid” but it doesn’t work for me (maybe I used it wrongly?). I was looking for something like “The path equals nothing” or “The path doesn’t equal its class” but nothing worked.
Please, any suggestion what should I look for?
