foreach loop with an array of GameObjects
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
{
//enemies[i].active = true;
}
}

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.
Thanks. Never got the hang of foreach statements but now I think I know what they are about.
Actualization to 2019
void OnTriggerEnter(Collider collider)
{
//activate enemies
foreach (GameObject enemy in enemies)
{
enemy.SetActive(true);
}
}
