public static void DrawLineList(ReadOnlySpan<Vector3> points)

Parameters

points

ReadOnlySpan<Vector3>

Pairs of points to use as the beginning and end of each line to draw. Unity throws an exception if

points

contains an odd number of elements.

Remarks

This function provides a more efficient way to draw multiple lines than repeatedly calling the Gizmos.DrawLine function for each one.

Each pair of points from the

points

span represents the start and end of each line, so Unity draws the first line from

points[0]

points[1]

, the next from

points[2]

points[3]

, and so on.


using UnityEngine;using System.Collections;public class ExampleClass : MonoBehaviour{    Vector3[] points;    void Start()    {        points = new Vector3[4]        {            new Vector3(-100, 0, 0),            new Vector3(100, 0, 0),            new Vector3(-100, 100, 0),            new Vector3(100, 100, 0)        };    }    void OnDrawGizmosSelected()    {        // Draws two parallel blue lines        Gizmos.color = Color.blue;        Gizmos.DrawLineList(points);    }}
