public static function DrawLines(lineSegments:
Vector3[]):
void;
public static void DrawLines(Vector3[] lineSegments);
Parameters
| lineSegments | A list of pairs of points that represent the start and end of line segments. |
Description
Draw a list of line segments.
"Draw multiple lines in sceneview.".
The following example uses DrawLines to draw a line between objects defined in a list.
To use this example, save the following script into the Assets/Editor folder:
using UnityEngine; using UnityEditor;
[CustomEditor( typeof( DrawLines ) )] public class DrawLinesEditor : Editor { void OnSceneGUI( ) { DrawLines t = target as DrawLines;
if( t == null || t.GameObjects == null ) return;
Vector3[] lineSegments = new Vector3[t.GameObjects.Length * 2]; int pointIndex = 0;
for( int i = 0; i < t.GameObjects.Length - 1; i++ ) { if( t.GameObjects[i] != null && t.GameObjects[i+1] != null ) { lineSegments[pointIndex++] = t.GameObjects[i].transform.position; lineSegments[pointIndex++] = t.GameObjects[i+1].transform.position; } }
Handles.DrawLines( lineSegments ); } }
...then attach this script to the anchor object which you would like to see lines eminate from. Drop GameObjects you would like lines drawing to into the array in the script's inspector, and adjust the gap between the dotted lines accordingly:
using UnityEngine;
[ExecuteInEditMode] public class DrawLines : MonoBehaviour { public GameObject[] GameObjects; }
public static function DrawLines(points:
Vector3[],
segmentIndices: int[]):
void;
public static void DrawLines(Vector3[] points,
int[] segmentIndices);
Parameters
| points | A list of points. |
| segmentIndices | A list of pairs of indices to the start and end points of the line segments. |
Description
Draw a list of indexed line segments.

if( t == null || t.GameObjects == null ) return;
Vector3[] points = new Vector3[t.GameObjects.Length]; int[] segmentIndices = new int[t.GameObjects.Length * 2]; int pointsIndex = 0;
for( int i = 0; i < t.GameObjects.Length; i++ ) { if( t.GameObjects[i] != null ) points[pointsIndex++] = t.GameObjects[i].transform.position; }
for( int i = 0; i < pointsIndex - 1; i++ ) { int segmentIndex = i * 2;
segmentIndices[segmentIndex] = i; segmentIndices[segmentIndex+1] = i+1; }
Handles.DrawLines(points, segmentIndices ); } }
