Vector3.Distance

Parameters

Returns

float The scalar distance between points a and b.

Description

Calculates the distance between two three-dimensional points.

This method calculates the shortest distance between the two input points. Both points should be defined in the same coordinate space. Vector3.Distance(a,b) returns the same result as (a-b).magnitude. The resulting value is always >= 0.

using UnityEngine;

public class Vector3DistanceExample : MonoBehaviour
{
    // the first point is this transform's position
    public Transform other;

    void Start()
    {
        if (other)
        {
            // the second point is the position of the MonoBehaviour's transform
            float dist = Vector3.Distance(other.position, transform.position);
            print("Distance to other: " + dist);
        }
    }
