Question by Genesis4545 · Feb 13, 2017 at 09:45 AM · backgroundscrollingparallax

2D scrolling background

Hi everyone! I'm currently trying to figure out a way to make my backgrounds scroll ONLY when the player is at a certain portion of the screen (right side). This is how I'm currently doing it:

     void Update()
     {
         if (player.transform.position.x > 2)
         {
             float x = Mathf.Repeat(Time.time * scrollSpeed, 1);
             Vector2 offset = new Vector2(x, savedOffset.y);
             GetComponent<Renderer>().sharedMaterial.SetTextureOffset("_MainTex", offset);
         }
     }

Now the problem I'm having is that whenever I cross that line where the players position.x becomes >2 there's a slight sort of freeze. The game runs just fine but the background stays static for a split second then jumps forward ever so slightly and continues to scroll normally. It's like it starts scrolling just a little bit before I can actually see it scrolling, and so it looks like the backgrounds just jump forward a little bit. Is the code I'm using just too slow to keep up or?

Any help is greatly appreciated, thank you!
