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;
}
