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 Scene view.
The following example uses DrawDottedLines to draw a line between GameObjects defined in a list.
To use this example, save the following script into the Assets/Editor folder:
#pragma strict @CustomEditor(DrawDottedConnectedLines) public class DrawDottedConnectedLinesEditor extends Editor { function OnSceneGUI() { var t: DrawDottedConnectedLines = target as DrawDottedConnectedLines; if (t == null || t.GameObjects == null)return ; var lineSegments: Vector3[] = new Vector3[t.GameObjects.Length * 2]; var pointIndex: int = 0; for (var i: int = 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); } }
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 GameObject which you would like to see lines come from. Drop GameObjects you would like the lines to go to into the array in the script's inspector, and adjust the gap between the dotted lines accordingly:
#pragma strict @ExecuteInEditMode public class DrawDottedConnectedLines extends MonoBehaviour { public var GameObjects: GameObject[]; public var DashSize: float = 4; }
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. |
Description
Draw a list of indexed dotted line segments.
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:
#pragma strict @CustomEditor(DrawDottedConnectedLinesUsingPoints) public class DrawDottedConnectedLinesUsingPointsEditor extends Editor { function OnSceneGUI() { var t: DrawDottedConnectedLinesUsingPoints = target as DrawDottedConnectedLinesUsingPoints; if (t == null || t.GameObjects == null)return ; var points: Vector3[] = new Vector3[t.GameObjects.Length]; var segmentIndices: int[] = new int[t.GameObjects.Length * 2]; var pointsIndex: int = 0; for (var i: int = 0; i < t.GameObjects.Length; i++) { if (t.GameObjects[i] != null) points[pointsIndex++] = t.GameObjects[i].transform.position; } for (var i: int = 0; i < pointsIndex - 1; i++) { var segmentIndex: int = i * 2; segmentIndices[segmentIndex] = i; segmentIndices[segmentIndex + 1] = i + 1; } Handles.DrawDottedLines(points, segmentIndices, t.DashSize); } }
using UnityEngine; using UnityEditor;
[CustomEditor( typeof( DrawDottedConnectedLinesUsingPoints ) )] public class DrawDottedConnectedLinesUsingPointsEditor : Editor { void OnSceneGUI( ) { DrawDottedConnectedLinesUsingPoints t = target as DrawDottedConnectedLinesUsingPoints;
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.DrawDottedLines(points, segmentIndices, 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:
#pragma strict @ExecuteInEditMode public class DrawDottedConnectedLinesUsingPoints extends MonoBehaviour { public var GameObjects: GameObject[]; public var DashSize: float = 4; }
using UnityEngine;
