Hi, I am trying to detect if food object contains to my player object’s sight, but angle is wrong by 90.
I wrote the same code as in this tutorial:

but when I log the angle is greater by 90:

So here is my code:
I don’t know what I am doing wrong really, object in the same layer and parent.

            var player = players*;*

var oneFood = food[j];
var foodToPlayer = oneFood.transform.position - player.transform.position;
var angle = Vector3.Angle(foodToPlayer, player.transform.forward);
Debug.Log(angle);

I found solution. Just switched x and z position. But I don’t know reason of this. So if anyone can explain me, I will be very grateful.
new code is:

            var foodToPlayer = oneFood.transform.position - player.transform.position;

            var playerForward = player.transform.forward;

            var angle = Vector3.Angle(foodToPlayer, new Vector3(playerForward.z, playerForward.y, playerForward.x));
