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]
to 
points[1]
, the next from 
points[2]
to 
points[3]
, and so on.
