Declaration

public void InvokeRepeating(string methodName, float time, float repeatRate);

Parameters

Parameter	Description
methodName	The name of a method to invoke.
time	Time to wait in seconds before the first invocation.
repeatRate	Interval in seconds between method invocations.

Description

Invokes the specified method after a specified delay, then repeatedly at the specified rate.

To cancel InvokeRepeating, use MonoBehaviour.CancelInvoke.

The time and repeatRate parameters depend on Time.timeScale. For example, a Time.timeScale of 2 effectively halves the real-time values of time and repeatRate, while a Time.timeScale of 0.5 doubles them. If Time.timeScale is 0, then the method is never invoked.

You can't change the value of the repeatRate interval while InvokeRepeating is running. You must cancel and re-invoke to change it.

using UnityEngine;
using System.Collections.Generic;// After an initial 2 second wait, launch a projectile every 0.3 seconds
public class ExampleScript : MonoBehaviour
{
    public Rigidbody projectile;
    void Start()
    {
        InvokeRepeating(nameof(LaunchProjectile), 2.0f, 0.3f);
    }
    void LaunchProjectile()
    {
        Rigidbody instance = Instantiate(projectile);
        instance.velocity = Random.insideUnitSphere * 5;
    }
}
