Handles.DrawLine

Parameters

Description

Draw a line from p1 to p2.

Draw Line in the Scene View.

The following example uses DrawLine to draw a line between an object and the objects defined in a list. To use this example, save the following script into the Assets/Editor folder:

using UnityEngine;
using UnityEditor;

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

		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.DrawLine( center, t.GameObjects[i].transform.position );
		}
	}
}

...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:

using UnityEngine;


[ExecuteInEditMode]
public class DrawLine : MonoBehaviour
{
	public GameObject[] GameObjects;
}
