How Do I Find a Location Given A Distance and a Vector?

Unity Engine

Hi, math question:

I need to find an end point location, given the following information:

Starting point
Vector of travel
Distance traveled

With these three pieces of info, how do I find the (x, y, z) location of the end point? Do I have to do some complex math, or is there a way to do this simply in Unity?

Is the vector of travel normalized?

If your travel vector is normalized:

startingPoint + vectorOfTravel * distanceTraveled

If it’s not normalized:

startingPoint + vectorOfTravel.normalized * distanceTraveled

I think you may be able to just multiply the normalized vector of travel by the distance, then add that product to the starting point.

Edit: Hairball beat me to it and was less lazy about it.

Excellent - thank you guys!
