Vector3.Angle

Parameters

Description

Возвращает угол в градусах между векторами from и to.

The angle returned is always the non reflex angle between the two vectors - ie the smaller of the two possible angles between them and never greater than 180 degrees.

using UnityEngine;

public class AngleExample : MonoBehaviour
{
	public Transform     target;

	// prints "close" if the z-axis of this transform looks
	// almost towards the target

	void Update ()
	{
		Vector3 targetDir = target.position - transform.position;
		float angle = Vector3.Angle( targetDir, transform.forward );

		if( angle < 5.0f )
			print( "close" );
	}
}
