Handles.DrawDottedLine

public static void DrawDottedLine(Vector3 p1, Vector3 p2, float screenSpaceSize);

Parameters

p1 The start point.
p2 The end point.
screenSpaceSize The size in pixels for the lengths of the line segments and the gaps between them.

Description

Draw a dotted line from p1 to p2.


Draw Line in the Scene view.

The following example uses DrawDottedLine to draw a line between a GameObject and the Game Objects defined in a list.

To use this example, save the following script into the Assets/Editor folder:

using UnityEngine;
using UnityEditor;

[CustomEditor( typeof( DrawDottedConnectedLine ) )]
public class DrawDottedConnectedLineEditor : Editor
{
	void OnSceneGUI( )
	{
		DrawDottedConnectedLine   t = target as DrawDottedConnectedLine;

		if( t == null || t.GameObjects == null )
			return;

		Vector3 center = t.transform.position;

		for( int i = 0; i < t.GameObjects.Length; i++ )
		{
			if( t.GameObjects[i] != null )
				Handles.DrawDottedLine( center, t.GameObjects[i].transform.position, 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:

using UnityEngine;
          
[ExecuteInEditMode]
public class DrawDottedConnectedLine : MonoBehaviour
{
	public GameObject[] GameObjects;
	public float DashSize = 4;
}
