Handles.DrawDottedLine

Parameters

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:

#pragma strict
@CustomEditor(DrawDottedConnectedLine)
public class DrawDottedConnectedLineEditor extends Editor {
	function OnSceneGUI() {
		var t: DrawDottedConnectedLine = target as DrawDottedConnectedLine;
		if (t == null || t.GameObjects == null)return ;
		var center: Vector3 = t.transform.position;
		for (var i: int = 0; i < t.GameObjects.Length; i++) {
			if (t.GameObjects[i] != null)
				Handles.DrawDottedLine(center, t.GameObjects[i].transform.position, t.DashSize);
		}
	}
}

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:

#pragma strict
@ExecuteInEditMode
public class DrawDottedConnectedLine extends MonoBehaviour {
	public var GameObjects: GameObject[];
	public var DashSize: float = 4;
}

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