The member `Clock.creaturesArray' cannot be used as method or delegate

Question

I was looking around and couldn't find an answer to what the above error means. I am trying to send a message in a script to the first object in an array and I get this error at the send message. Here's the script.

 using UnityEngine;
 using System.Collections;
 
 public class Clock : MonoBehaviour {
 
     public int hour;
     public int minute;
     public int second;
     public bool PM;
     public int n;
     public ArrayList playerCreatures;
     public object[] creaturesArray;
     
     // Use this for initialization
     void Start () {
     
         hour = 12;
         minute = 0;
         PM = false;
         second= 0;
         n=1;
         playerCreatures.Add(GameObject.Find("Bullark_Elec_v1"));
         creaturesArray = playerCreatures.ToArray();
         
     }
     
     // Update is called once per frame
     void Update () {
     
         if ( Time.time >= second){
             second ++;
             minute++;    
             
         }
         
         if ( minute == 60){
             hour++;
             minute = 0;    
             
         }
         if (hour > 23){
         hour = 0;    
             
         }
     
         if ( second == n*4){
             
             
             creaturesArray(1).SendMessage(Stamina, hour);
             
             n++;
             
         }
     }
 }

thanks for an explanation!

First of your creatureArray is of type "object". An Object doesn't have a SendMessage function. It should be of type GameObject since SendMessage is a function of GameObject.

Your actual problem is that you used round brackets which are only used for methods. You need square brackets [].

creaturesArray[1].SendMessage(Stamina, hour);

Keep in mind that index 1 is the second object in the array. 0 is the first one. Also don't forget if you try to use an index that doesn't exist you'll get a runtime error.

edit
Well, another problem is this line:

creaturesArray = playerCreatures.ToArray();

because you use the ArrayList. The ArrayList class stores untyped objects. You better use a generic list instead:

public List<GameObject> playerCreatures;

Don't forget to include this namespace:

using System.Collections.Generic;

I don't get why you even use a containerclass. It contains one element, so you can just put it into the array.

In Start() you can do this:

creaturesArray = new GameObject[] { GameObject.Find("Bullark_Elec_v1") };

or

creaturesArray = new GameObject[1];
creaturesArray[0] = GameObject.Find("Bullark_Elec_v1");

If you plan to store more than one object, you can just use the List<>. Why do you even use an array? ;)

i keep getting this error though when i put it as a GameObject. I think thats why i changed it to object Cannot implicitly convert type object[]' to UnityEngine.GameObject[]'. An explicit conversion exists (are you missing a cast?)
