Problem calling method

Unity Engine
1

I have a very basic horse race game (cube race actually). My ‘horse’ has a script

using UnityEngine;
using System.Collections;

public class Horse : MonoBehaviour 
{

	
	public void Run()
	{
		transform.position += new Vector3(Random.Range(0,0.1f), 0, 0);
	}
}

and I have an empty GameObject with a script

using UnityEngine;
using System.Collections;

public class Race : MonoBehaviour 
{
	public GameObject[] horses;

	void Start () 
	{
		horses = GameObject.FindGameObjectsWithTag("horse");
	}
	
	void Update () 
	{
		for(int i=0;i<horses.Length;i++)
		{
			horses[i].Run();
		}
	}
}

but Unity does not want to run my Run() method. Something about no extensino method or missing assembly reference etc. Is there some magic word I should be using? The code is very incomplete at this stage, but I need to get this working first.

It’s because “horses” is an array of game objects. You have to get the Horse component from the game objects.

horses*.GetComponent().Run()*

Thank you, much appreciated :smile: I’m coming to this from Java and still getting my head around the Unity engine/Scripting interactions.
