You can achieve that by doing something like this:
Basically, find the direction vector from your previous frame location to current location. Then multiply it by the total trace distance required and add the resulting vector to the previous frame location. So this should give you a point ahead of the actor in the direction that you’re traversing. I hope that is what you were asking for.
As for the previous frame location, you can store it in a variable after you’ve performed your trace operation so that it can be used in the next frame. Also make sure that you’re using a trace channel that is not blocked by the actor.
