Detect if player is facing an Object
i'm making a game where my player will change position if he is facing an object (90°) any help to make that detection ?
An alternate to @DajBuzi's solution:
var v = object.position - transform.position;
if (Vector3.Angle(v, transform.forward) <= 45.0) {
Debug.Log("I'm facing the object");
}
This is 45 degrees either size for a total of 90. If you want a full 180 degrees, you can use Vector3.Dot() and look for a positive result. Also if the pivot points are different heights, you might want to zero out the 'y' value before doing the comparison. Note sure of your goal.

Hello,
I would recomment you to use Raycast:
Ray ray = new Ray(transform.position, transform.forward);
RaycastHit hit;
if(Physics.Raycast(ray, out hit, 100)){
//check if it hits desired object
// and do some logic
}
Attach this to your player and check the results.
transform.position is your player position transform.forward is your player forward direction
