enemy teams used FindGameObjectWithTag("teamx");

hello peopple i´m noob in unity and i have a problem to make a combat team sistem.
i try to make all units of team1 (for example) can attack to a random unit of team 2 .

in my code all units of the team attack the same unit and i have no idea how to make the units to attack ramdomly.

Code (csharp):

1.  
2.  
3. var Estado : int = 0;
4.  
5. var Target: GameObject; //El objetivo
6.  
7. private var RotInic : Quaternion;
8. var RotSpeed : float;
9.  
10. var VelMov : float;
11. var gravity : float = 9.8;
12.  
13. private var DistanciaCont : float;
14. var DistEnem : float = 0.5;
15.  
16. private var contador = 0.0;
17.  
18. //Animaciones
19.  
20. var IdleAnim : AnimationClip;
21. var RunAnim : AnimationClip;
22. var GuardAnim : AnimationClip;
23. var AttackAnim : AnimationClip;
24.  
25. var MuerteAnim : AnimationClip;
26.  
27. function Start ()
28. {
29.    //wrapMode puede ser: Once, Loop, PingPong, Default o ClampForever
30.    animation[IdleAnim.name].speed = 1;
31.    animation[IdleAnim.name].wrapMode = WrapMode.Loop;
32.  
33.    animation[RunAnim.name].speed = 1;
34.    animation[RunAnim.name].wrapMode = WrapMode.Loop;
35.  
36.    animation[GuardAnim.name].speed = 1;
37.    animation[GuardAnim.name].wrapMode = WrapMode.Loop;
38.  
39.    animation[AttackAnim.name].speed = 1;
40.    animation[AttackAnim.name].wrapMode = WrapMode.Once;
41.  
42.    animation[MuerteAnim.name].speed = 1;
43.    animation[MuerteAnim.name].wrapMode = WrapMode.ClampForever;

FindGameObjectWithTag only returns the first available object with that tag. Why not try using FindGameObjectsWithTag and then picking a random entry from the array that returns? Make sure you cache the results though, you don't want to be finding an array of objects like that every frame.

http://docs.unity3d.com/ScriptReference/GameObject.FindGameObjectsWithTag.html

 

mmm i read the documentation but i dont understand how to make what you say

 

if i put this in update fuction
var gos : GameObject[];
gos = GameObject.FindGameObjectsWithTag("Enemy");

its work fine or make an error?

or i need make another function and return a random numer,and that number is the number of the enemy unit?

 

That will return an array of GameObjects with the tag "Enemy". If that's what you're trying to do then you got it

 

i dont not if i can use this in the function update but i will try
var gos : GameObject[];
gos = GameObject.FindGameObjectsWithTag("Enemy");

ok i will do that , thanks to all

 

tks ,
its work
