public static function DrawDottedLines(lineSegments:
Vector3[],
screenSpaceSize: float):
void;
public static void DrawDottedLines(Vector3[] lineSegments,
float screenSpaceSize);
Parameters
| lineSegments | A list of pairs of points that represent the start and end of line segments. |
| screenSpaceSize | The size in pixels for the lengths of the line segments and the gaps between them. |
Description
Draw a list of dotted line segments.
"Draw multiple dotted lines in sceneview."
The following example uses DrawDottedLines 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( DrawDottedConnectedLines ) )] public class DrawDottedConnectedLinesEditor : Editor { void OnSceneGUI( ) { DrawDottedConnectedLines t = target as DrawDottedConnectedLines;
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.DrawDottedLines( lineSegments, t.DashSize ); } }
...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 DrawDottedConnectedLines : MonoBehaviour { public GameObject[] GameObjects; public float DashSize = 4; }
public static function DrawDottedLines(points:
Vector3[],
segmentIndices: int[],
screenSpaceSize: float):
void;
public static void DrawDottedLines(Vector3[] points,
int[] segmentIndices,
float screenSpaceSize);
Parameters
| points | A list of points. |
| segmentIndices | A list of pairs of indices to the start and end points of the line segments. |
| screenSpaceSize | The size in pixels for the lengths of the line segments and the gaps between them. |
