Exclude self in 'findgameobjectswithtag' ?

Question

I have multiple characters with the same tag that needs to pick a random other character and interact with them. Kind of like how the puppies in nintendogs would randomly pick another dog to play with. How do I exclude them from including themselves in the found objects?

ie

 enter code here

var peoples:GameObject[];
var person : GameOject;

Update(){
peoples = GameObject.FindGameObjectsWithTag("Humans");
}

function Interact(){
person = peoples[Random.Range(0, peoples.length)] // (except yourself somehow...);
// go and talk to random person

}

thank you

An easy fix would be to just tag your player to somet$$anonymous$$ng other than "Human". However, im sure you already structured code to use t$$anonymous$$s method for regularly called functions. Sounds like you will need to switch to Array(), convert the array to be re-sized then convert back, or use the Generic List so you can remove the slot in the array. Again, if possible, just switch the tag of your player.

@superventure Hey there! :) I have a pretty late answer (5 years :D ), but someone who stumbles upon t$$anonymous$$s may found use of it.

     var people : GameObject[];
     var person : GameObject;
 
     function Update(){
         t$$anonymous$$s.gameObject.tag = "Counter"; //temporary tag
         people = GameObject.FindGameObjectsWithTag("Human"); //find everyt$$anonymous$$ng
         Debug.Log("Found "+people.length+" people.");
         t$$anonymous$$s.gameObject.tag = "Human"; //change your tag back
     }
 
     function Interact(){
         person = people[Random.Range(0, people.length)];
         // go and talk to random person
         Debug.Log("Random person: "+person.name);
     }
