Im trying to make a Java script that detects how many tags of Enemy are still alive. How exactly do i do that?

Questions & Answers

I have a tag named enemy. The script is supposed to detect how many enemy tags are alive and if there are none, the game loads the next scene.

var Enemy = tag {
if (Enemy = 0) {

Application.Loadlevel(“win”);

}
}

You could use the following:

var enemiesLeft:int;

function Update()
{
	for(var badGuys : GameObject in GameObject.FindGameObjectsWithTag("Enemy"))
    	{//Find anything with the tag Enemy
        	enemiesLeft++;
        	//Every time you find an enemy add it to a the total number of enemies
        }
            
    Debug.Log(enemiesLeft);
    //Use Debug.Log to keep a track of numbers while testing and debuging.
	//Delete once you know the code is sound

    if (enemiesLeft==0)
    {
                Application.Loadlevel("win");
    }
}

But Crazydadz is correct. This will take up a bit of juice.

You’re better doing something along the lines of the following
Have a script called “LevelControl”(this is important for later):

static var enemiesLeft[:int;

function Start()
{//This will happen once at the beginning of each level just to find total number
for(var badGuys : GameObject in GameObject.FindGameObjectsWithTag("Enemy"))
	{
	enemiesLeft++;
	}
}

function Update()
{
if (enemiesLeft==0)
    {
     Application.Loadlevel("win");
    }
}

Then have a script attached to the enemy that when they’re destroyed the following line is actioned.

LevelControl.enemiesLeft--;
//When dead take one away from the enemiesLeft variable in the script LevelControl

Hope that solves your problem.

What I do with pretty much all my instantiable classes now is this:

using System.Collections.Generic;

public class Mine : MonoBehaviour {
  public static List<Mine> instances = new List<Mine>();

  void OnEnable() {
    instances.Add(this);
  }
  void OnDisable() {
    instances.Remove(this);
  }
}

...

Debug.Log("There are currently " + Mine.instances.Count + " mines");
