I cant get wall jumping to work in my 2D platformer (C#)

I coded this script in C#

I've pasted below the code for my entire player controller. Jumping and double jumping works fine but whenever i wall jump it just go's up the wall but doesn't push away from it. I am trying to get wall jumping similar to supermeatboy.

I thought it had something to do with the "moveVelocity = 0f;" which would just stop the player in mid air but i don't think that is the only problem because i put that in a "If (WallJumped == false)" so that if you did wall jump then it shouldn't stop your velocity. Any help would be greatly appreciated thanks.
