Gizmos.DrawLineList

Parameters

Description

Draws multiple lines between pairs of points.

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] to points[1], the next from points[2] to 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);
    }
}
