title: Suggestions on making a HUD radar overlay in unity
body: <p>I've been getting a lot of help by reading questions on the forum, but got to a point that what I'm looking for does not appear to be asked, so, here goes my first question.</p>
  
  <p>I'm quite a rookie at coding, and I'm trying to make an small 3D game. Everything's going well so far, but I'm stuck at making a radar overlay.</p>
  
  <p>This is an example of what I'm going for. <a href="https://drive.google.com/file/d/1AoGYRegc8hI8tC0-GJM2OjXfSg2VBUxj/view?usp=sharing" rel="nofollow noreferrer">https://drive.google.com/file/d/1AoGYRegc8hI8tC0-GJM2OjXfSg2VBUxj/view?usp=sharing</a></p>
  
  <p>I want to create an overlay over every enemy with a tag "Enemy". Can get an array with every GameObject with the tag, but have not found a way to create a GameObject over every item on the list and delete it whenever it's not on the list anymore.</p>
  
  <p>Any suggestions?</p>
