No, my variables were well instantiated. There was no null pointer.
I think for some reason it’s just not possible to use a timeline from within a component. At least from a Bluprint it is not possible.
However the people in the attached post did it. Or so it seems…
Well, in my case the sine function did the job quite well. I even think it is more efficient and requires fewer resources.
But I recognize that if the curve is more complicated than the sine it can be a big disadvantage.
So I really don’t know what’s going on, but the truth is that it doesn’t work.
It’s a shame
