Question by sarah22 · Aug 20, 2017 at 05:00 AM · raycastmathdirection

How to get the direction vector given a point and rotation?

So basically I have the player position and its rotation value. How can I get the facing direction so i can use that for raycast.

Thank you.

You should be able to use .forward in order to raycast in the direction you are facing.

To further elaborate on this, transform.forward is already calculated like this by Unity:

 // This is already the value of transform.forward -- you don't need to actually use this
 transform.forward = transform.rotation * Vector3.forward;
