Unity2D raycast to check for a wall, Issues. ~Still not solved...Anybody?~

Hello my fellow Unity friends I have an issue.

I'm using a basic blink (teleport) ability which just directly shifts the player's transform. the problem is I have certain walls I don't want the player to be able to teleport through. I'm trying to use the below script to prevent the player when they are at a 1.5 distance from the "Barriers". This distance is the exact blink distance the player can move. Edit: This function is called in a fixed update

If any more information is needed, I have more. Thank you all in advance! :D

Edit (1/1/2018): Code now gives the error: NullReferenceException: Object reference not set to an instance of an object Blink.BarrierCheck () (at Assets/Scripts/Hope/Abilities/Blink.cs:41) Blink.FixedUpdate () (at Assets/Scripts/Hope/Abilities/Blink.cs:30)
