Handles.DrawPolyLine

Description

Рисует линию через список всех точек (/points/).

Важно: Используйте HandleUtility.GetHandleSize если вам нужны маркеры постоянного размера.


PolyLine that connects all the objects in the Scene view.

The following example uses DrawPolyLine to draw a line between a number of GameObjects in the Scene view.

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

using UnityEngine;
using UnityEditor;

[CustomEditor( typeof( DrawConnectedLine ) )]
public class DrawConnectedLineEditor : Editor
{
	// Draw lines to the connected game objects that a script has.
	// if the target object doesnt have any game objects attached
	// then it draws a line from the Last checked object to 0,0,0

	void OnSceneGUI( )
	{
		DrawConnectedLine   t = target as DrawConnectedLine;

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

		Vector3[] positions = new Vector3[t.GameObjects.Length];

		for( int i = 0; i < t.GameObjects.Length; i++ )
		{
			if( t.GameObjects[i] != null )
				positions[i] = t.GameObjects[i].transform.position;
			else
				positions[i] = Vector3.zero;
		}

		Handles.DrawPolyLine( positions );
	}
}

...and attach the following script to a GameObject in the Scene. Drag and drop GameObjects onto the GameObject's array inspector, corresponding to the objects where you would like to see the line drawn between:

using UnityEngine;

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