Help create a trail to follow a gameobject

Hi just wanted to know or can you guys can suggest me how can i leave a trail to follow that certain object . Just like here i want my GameObject to leave a trail so that my character can follow it. and i have read some scripts but it just make my gameobject and my character attract to each other.

 

Code (csharp):

1. TrailRenderer

 

yeah ive read about that but how do you apply it?

 

Create a new scene and look up a good tutorial on Trail Renders. That might be overkill because it literally takes 1 min to understand what it does and how to work it. But create a new scene and try to practice a bit on using it. Also, when you say that the trail render makes your AI and player attract to each other, that is a problem on your part and you have a bug. Either post the script here or on the Unity Answers page but if not, we really can't help you much
