SphereCollider.radius

描述

以对象局部空间为单位测量的球体半径。

球体半径将按变换的缩放比例进行缩放。

using UnityEngine;

//Always attach a SphereCollider component to your GameObject
public class Example : MonoBehaviour
{
    //This declares your SphereCollider
    SphereCollider myCollider;

    void Start()
    {
        //Assigns the attached SphereCollider to myCollider
        myCollider = GetComponent<SphereCollider>();
    }

    void OnTriggerEnter(Collider other)
    {
        //This increases the Collider radius when the GameObject collides with a trigger Collider
        myCollider.radius += 2f;
    }
}
