how do you target every game object with the same tag name?

Unity Engine

Basically, my question is the same as the title.

Does any one know?

GameObject[] gameObjects = GameObject.FindGameObjectsWithTag("tag name")

Thanks for the reply, but I’m a bit confused about how to add it correctly.

What I am trying to do is located right here.

This is my code. I’m not sure what is wrong with it, but it keeps telling me I have an error:

var all : GameObject = GameObject.FindGameObjectsWithTag("alien");
		all.transform.Translate(0, moveV * Time.deltaTime, 0);

You should have a look in the documentation, Unity - Scripting API: GameObject.FindGameObjectsWithTag

GameObject.FindGameObjectWithTag returns a list of all GameObjects with the tag you specify. You then have to iterate through that list to access each and every one of those objects.

I don’t work with javascript myself, but I think the code you’re looking for is something along the lines of

var all : GameObject[] = GameObject.FindGameObjectsWithTag("alien");
for (var alien : GameObject in all)
   alien.transform.Translate(0, moveV * Time.deltaTime, 0);

So rather than reference objects directly you always have to work with arrays?

The documentation for FindGameObjectsWithTag specifically says it returns a GameObject array. So in this case, yes.

You can always make a variable equal one of the objects in that array though. So, no, you do do not always have to work with arrays.
