title: How can I check if an object exists at a specific position in unity C#?
body: <p>In this case I am looking to full an empty area with an object but I do not want to place an object there if the area is not empty.
  This is specifically talking about a cube so I am not sure if the checkSphere() works.
  I am a beginner and I had a lot of trouble finding an answer to this question so although I know it is probably online I had trouble finding something that explained the code in a way I understood and even finding that code. </p>
