Here's my situation. I'm coding scripts for a turn-based game that has an initiative system. Sometimes I need all of the planes to go first, sometimes the ground units, sometimes all the enemies, etc. The FindObjectsWithTag has such good functionality, but tagging an object based on its vehicle type means I can't tag it "player" or "enemy" (which makes things harder in other areas). Is there any way to have more than one tag so that I can iterate through my objects easily? Or is there another strategy in Unity that will get me what I want (simply iterating through planes.Move() after defining "planes" with FindObjectsWithTag is sooo convenient...).
i have a strange solution for you, check here:-
it's a script that allows you to put in Multiple tags on an object...
Angad do you still have that script, the website is tits up. Can you post it here for records?
dead link. Please remove the answer or reupload.
I was looking for a way to do this multi-tag thing as well and happened across the correct URL.
Scroll down to where it says "Unity script that allows multiple tags".
I have yet to try it. Looks pretty basic though.

It is not currently possible, but i use a work-around.
On gameObjects that i need more than one tag on, i add an empty game objects as a child for each tag i need, and give each of these separate tags.. Then you can still search for tags using FindGameObjectsWithTag then just reference the parent object.. as an example in C#
sensedObjects = GameObject.FindGameObjectsWithTag(theTag);
foreach (GameObject foundOne in sensedObjects)
GameObject objectMain = foundOne.transform.parent.gameObject;
That's a really good idea! I'll give it a shot. Thanks!
Brilliant! :D That will help me a lot! :D
awesome idea dude...i'll implement this...

When i want to multi-tag something i create Acronyms for the tags
Ally = All
Minion = Min
Champion = Chm
So when i want for some object to have multiple tags i tag it with a string containing several of them.
ex : "EnChm" (for Enemy Champion) contains "Ch" , and i get by with doing the regular checks :
I like this better. Seems like it will have way better performance... although there should be a best practice on this kind of object tagging and search.
I would even put a tag separator character between tags just for clearance. Also I would avoid using acronyms for better readability.
HAHA good idea! I liked it
If you had a lot of tags, this would begin to get really difficult to manage since you have to input new tags manually in the editor.

I created a simple asset called Tag Frenzy that allows you use multiple tags in Unity. It is (in my opinion) as easy to use as the built in tag system. You can see it in action here. I'd encourage you to check it out if you don't want to manually add child gameobjects like in the solution above.

Or you could use FindObjectsOfType instead
var planes = FindObjectsOfType<Plane>();
I love this in concept, but according to Unity docs FindObjectsOfType is very slow...

A GameObject has onlyOne tag It cannot contain more than one tag. There r many different ways to find that tag. e.g compare tag. findgameobject with tag etc
