So, I am using the wall jump function fromthe Lerpz tutorial for my new player controller script, however, the one from the lerpz tutorial allows walljumping on anything you collide with to the side. I want to limit the wall jumping to ony certian onbject only. From what I can see, this is what allows that:

// Store when we first touched a wall during this jump
if (collisionFlags == CollisionFlags.CollidedSides)
{
    touchWallJumpTime = Time.time;
}

I want to only allow walljumping on objects in a particular layer (or tag) only so that the player can't walljump on any object. Here is the complete function:

function ApplyWallJump ()
    {
        // We must actually jump against a wall for this to work
        if (!jumping)
            return;

        //if (!letGo)
        //  return;

        // Store when we first touched a wall during this jump
        if (collisionFlags == CollisionFlags.CollidedSides)
        {
            touchWallJumpTime = Time.time;
        }

        // The user can trigger a wall jump by hitting the button shortly before or shortly after hitting the wall the first time.
        var mayJump = lastJumpButtonTime > touchWallJumpTime - wallJumpTimeout && lastJumpButtonTime < touchWallJumpTime + wallJumpTimeout;
        if (!mayJump)
            return;

        // Prevent jumping too fast after each other
        if (lastJumpTime + jumpRepeatTime > Time.time)
            return;


        if (Mathf.Abs(wallJumpContactNormal.y) < 0.2)
        {
            wallJumpContactNormal.y = 0;
            moveDirection = wallJumpContactNormal.normalized;

            // Wall jump gives us at least trotspeed
            moveSpeed = Mathf.Clamp(moveSpeed * 1.5, trotSpeed, runSpeed);
        }
        else
        {
            moveSpeed = 0;
        }

        verticalSpeed = CalculateJumpVerticalSpeed (jumpHeight);
        DidJump();
        SendMessage("DidWallJump", null, SendMessageOptions.DontRequireReceiver);
        Debug.Log("Stupid Wall!");
    }
