Hello, I hope whoever reads this post is safe and well in this difficult times.
I’m fairly new to blueprints and anything related to code so I have a question that might not be that interesting, in advance I’m sorry for that.
My questions are in regards of Timelines:
Thank you very much for you time in advance, stay safe!
Hi -
Timelines are basically a more systematic way of using tick. In other words, the Update pin runs every frame.
Using lots of timelines is not a problem, but something computationaly heavy on the update pin is.
Just like with tick.
Also timelines are using curves. I don’t think curves are “baked”, so they get evaluated every time you get a value from it. In a curve are polynomes (I guess) like a + bt + ct² + dt³ +… So with very much timelines respectively curves there could be much to compute. Maybe it’s better to “bake” the timeline to the memory (in an own class) and store the values in an array and later make a simple interpolation. E.g. if the curve is t² then “bake” the timeline with a predefined stepsize, e.g. 0.5, to an array with the values y = 0.25, 1, 2.25, 4, 6.25, 9, … and use these values. If you want to evaluate it at t = 1.2, then use the nearest y-value, so y = 1. If t = 1.3, then use y = 2.25. Just a guess that this could be more performant. But this should only matter if using really much timelines and/or curves.
