How to calculate direction between 2 objects

Hi guys, I’m trying to figure out how to calculate the direction between 2 objects. I already got this.

		Debug.DrawLine (camera.transform.position, this.transform.position, Color.red, Mathf.Infinity);

With this code i get a DrawLine between object 1 (camera) and object 2 (my object)
But i need the line to go further then just object 2, so I need to know the direction/angle or something.

So my question is:
How to calculate the direction/angle or something between these objects.

Let’s say camera is your point A, and this is your point B.

Vector3 AB = B - A. Destination - Origin.

This is a direction and a distance. To have only the direction (and a distance of 1), you have to normalize it.

AB = AB.normalized OR AB.Normalize()

In your case :

Vector3 pos = camera.transform.position
Vector3 dir = (this.transform.position - camera.transform.position).normalized
Debug.DrawLine (pos, pos + dir * 10, Color.red, Mathf.Infinity);
