public void Invoke (string methodName, float time);



If time is set to 0, the method is invoked at the next Update cycle. In this case, it's better to call the function directly.

For better performance and maintability, use Coroutines instead.

using UnityEngine;
using System.Collections.Generic;

public class ExampleScript : MonoBehaviour { // Launches a projectile in 2 seconds

Rigidbody projectile;

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

void LaunchProjectile() { Rigidbody instance = Instantiate(projectile); instance.velocity = Random.insideUnitSphere * 5.0f; } }
