MonoBehaviour.InvokeRepeating

Description

在 time 秒后调用 methodName 方法，然后每 repeatRate 秒调用一次。

注意：如果将时间刻度设置为 0，该函数不起作用。

using UnityEngine;
using System.Collections.Generic;

// Starting in 2 seconds.
// a projectile will be launched every 0.3 seconds

public class ExampleScript : MonoBehaviour
{
    public Rigidbody projectile;

    void Start()
    {
        InvokeRepeating("LaunchProjectile", 2.0f, 0.3f);
    }

    void LaunchProjectile()
    {
        Rigidbody instance = Instantiate(projectile);

        instance.velocity = Random.insideUnitSphere * 5;
    }
}
