Is any invoke on methodName pending?

	// Instantiates a project after 2 seconds when Space key was pressed
	// and it will only call the function after the function has ended its execution
	var projectile : Rigidbody;
	function Update() { 
		if(Input.GetKeyDown(KeyCode.Space) && !IsInvoking("LaunchProjectile"))
			Invoke("LaunchProjectile", 2);
	}
	function LaunchProjectile () {
		var instance : Rigidbody = Instantiate(projectile);
		instance.velocity = Random.insideUnitSphere * 5;
	}

using UnityEngine;
using System.Collections;

public class Example : MonoBehaviour {
    public Rigidbody projectile;
    void Update() {
        if (Input.GetKeyDown(KeyCode.Space) && !IsInvoking("LaunchProjectile"))
            Invoke("LaunchProjectile", 2);
        
    }
    void LaunchProjectile() {
        Rigidbody instance = Instantiate(projectile);
        instance.velocity = Random.insideUnitSphere * 5;
    }
}

import UnityEngine
import System.Collections

public class Example(MonoBehaviour):

	public projectile as Rigidbody

	def Update() as void:
		if Input.GetKeyDown(KeyCode.Space) and (not IsInvoking('LaunchProjectile')):
			Invoke('LaunchProjectile', 2)

	def LaunchProjectile() as void:
		instance as Rigidbody = Instantiate(projectile)
		instance.velocity = (Random.insideUnitSphere * 5)

Is any invoke pending on this MonoBehaviour?
