I’m not sure what I am doing wrong

error CS0030: Cannot convert type UnityEngine.GameObject' to int’

Code:

public GameObject[] enemies; //dragged 6 GameObjects into Inspector

void OnTriggerEnter(Collider collider)
{
	//activate enemies
	foreach (int i in enemies) //the line the error is pointing to
	{

  • }*
    }

The right way to do it is:

void OnTriggerEnter(Collider collider)
{
    //activate enemies
    foreach (GameObject enemy in enemies)
    {
       enemy.active = true;   
    }
}

The instruction foreach loops through all elements in the group using internal pointers or indexes; you just supply a variable of the correct type, and foreach assigns to it a new element each iteration.

Actualization to 2019

    void OnTriggerEnter(Collider collider)
        {
            //activate enemies
            foreach (GameObject enemy in enemies)
            {
               enemy.SetActive(true);   
            }
        }
