Description 描述

Implement OnDrawGizmos if you want to draw gizmos that are also pickable and always drawn.

This function does not get called if the component is collapsed in the inspector.

JavaScript:

function OnDrawGizmos() {
	// Draw a yellow sphere at the transform's position
	Gizmos.color = Color.yellow;
	Gizmos.DrawSphere (transform.position, 1);
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void OnDrawGizmos() {
        Gizmos.color = Color.yellow;
        Gizmos.DrawSphere(transform.position, 1);
    }
}
