Looping through generic list and comparing index with random number?

Scripting
1

I want to iterate through a generic list and compare the current index with a random number. The code below doesn’t run as it tries to compare type Door with type Int. I want to compare the index position (integer?) with an integer number, not the type itself. Any help is appreciated!

public Door door;
public Vector3 pos;
public List<Door> doors = new List<Door>();

...

Door newDoor = Instantiate (door, pos, Quaternion.identity) as Door;
doors.Add(newDoor);

...

int num = Random.Range (0, doors.Count);
for (int i = 0; i < doors.Count; i++) {
    if (doors[i] == num) {
        // Do this
    }
}
2 
if(i == num) {
    // Do this
}

Or…don’t loop at all?

doors[num]

That’s … even better. To add to my question, I want to change these two variables of the instantiated door in my list at the position num. However, I can’t for the life of me figure out how to do that.

I would want to write door[num].doorTag = “something” but that doesn’t work, I seem only to be able to change the variables for the class itself, not the instantiated object.

public class Door : MonoBehaviour(){

    public string doorTag;
    public bool isTagged;

}

You’re trying to change the tag on the GameObject?

doors[num].gameObject.tag = "something";

I am trying to change my custom variables that the GameObject inherits from my custom class, but only on that instantiated GameObject in index position num. That variable is a string called doorTag, not the tag on the GameObject (confusing variable names on my part).

Then what you wrote should work fine.

Just got home and tried it. Thank you very much! :slight_smile:
