You don’t have a script called Enemy. You need to have such a script to call FindObjectsOfType<Enemy>().

Also, please use Code tags next time :slight_smile: They will make your code in the forum easier to read - example:

using System;

namespace HelloWorld
{
  class Program
  {
    static void Main(string[] args)
    {
      Console.WriteLine("Hello World!");
    }
  }
}
