Wall jumping problem

Hey guys!

Im having an issue I hope you can help me out with, currently I'm making a game that has a ball that you can control and jump. The problem is that when I jump on a wall it glides all the way up!

I tried using tags for the ground and such but that does not help as there will be obstacles you must jump over so you can still glide over those.

I also tried to use a character controller, but this just broke the entire thing and it just floats there?

The object I'm trying to control has the attached script, a rigidbody and sphere collider

Thanks for taking a look at my problem!

 var power = 50.0;  //speed of the ball
 var drag = 2.0; //how much to slow down when not controlling
 private var grounded = false; 
 var once = 0;  //var to set the direction of ball jump only once
 var jumpForce;  //var to set how high the ball should bounce
 
 function FixedUpdate () {
  // Only apply forces if the ball is on the floor
  if (grounded) {
   // Calculate the direction in which we want to roll the ball
   // * It is relative to the camera
   // * we remove the y component because we really want to apply forces only on the 2D plane

   else
    rigidbody.drag = 0; 
  }
  // Every frame set grounded to false. OnCollisionStay will enable it again if
  // the rigidbody collides with anything

  grounded = true;
  }
