Question by dAnk_shEEt · Apr 14, 2015 at 06:22 AM · camerabackgroundartifacts

2D Game: When moving the camera the background glithces

Hello Unity Community!

I am working on a 2D side-scroller. I have started to work on the script for the camera. I am pretty much done with it, but I have noticed something while testing.

When I run the application, and move my player the background seems to tare. At this point in time I am using simple solid colored squares with a black outline. The outline is there so I could make sure that there was no overlapping in their placement.

When I move the player left and right I notice that I am getting an artifact from the background moving. It looks as if there is Z's. The odd part is I don't get this when I am moving up and down.

Screenshots will not show this, but here is my code.

 using UnityEngine;
 using System.Collections;
 
 public class CameraController : MonoBehaviour {
     Vector3 zero = Vector3.zero;
     // Use this for initialization
     void Start () {
     }
 
 
     // Update is called once per frame
     public void Update (Vector3 playerPosition) {
         float positionDifX = Mathf.Abs (playerPosition.x - transform.position.x);
         float positionDifY = Mathf.Abs (playerPosition.y - transform.position.y);
         if (positionDifX > 0.5f || positionDifY > 0.5f) {
             
             Vector3 newCameraPosition = new Vector3(playerPosition.x,playerPosition.y,-10f);
             camera.transform.position = Vector3.SmoothDamp(camera.transform.position,newCameraPosition,ref zero,0.1f);
     }
 }

Any input will be greatly appreciated. Thanks for reading.
