Question by hwale · Aug 28, 2015 at 11:11 AM · c#camera gameobject blinking

Why are my 2D sprite GameObjects blinking and how do I fix this problem?

Hello. Firstly, I'd like to apologize because my code may be sloppy. I am a beginner. I wanted to have the camera follow the player game object which is a 2d sprite so I found a c# script online to work with. I only wanted the camera to follow the object along the Y-Axis and stay put along the X-Axis so I edited the script a bit. Before I made my changes, the 2d sprite game objects did not blink on play. After I made changes so that the camera did not move along the X-Axis, my 2d sprite game objects started to blink on play. Here is a video: https://youtu.be/0B9kkjXAPDs

Here is my code:

 using UnityEngine;
 using System.Collections;
 
 public class SmoothCamera : MonoBehaviour {
     
     public float dampTime = 0.15f;
     private Vector3 velocity = Vector3.zero;
     public Transform player;
     
     Vector3 currentPos;
     
     private float xCam;
     
     void Start() {
     
     xCam = GetComponent<Camera>().ViewportToWorldPoint(new Vector3(0.5f, 0, 0)).x;
     
     }
     
     void FixedUpdate () 
     {
             Vector3 point = GetComponent<Camera>().WorldToViewportPoint(player.position);
             Vector3 delta = player.position - GetComponent<Camera>().ViewportToWorldPoint(new Vector3(0.5f, 0.5f, point.z));
             Vector3 destination = transform.position + delta;
             currentPos = new Vector3(xCam, transform.position.y, point.z);
             transform.position = Vector3.SmoothDamp(currentPos, destination, ref velocity, dampTime);
     }
 }

I fixed it. I made some more changes to the code I found.

 using UnityEngine;
 using System.Collections;
 
 public class SmoothCamera : $$anonymous$$onoBehaviour {
     
     public float dampTime = 0.15f;
     private Vector3 velocity = Vector3.zero;
     public Transform player;
     
     Vector3 currentPos;
     Vector3 destination;
     
     private float xCam, zCam;
     
     void Start() {
     
     xCam = GetComponent<Camera>().ViewportToWorldPoint(new Vector3(0.5f, 0, 0)).x;
     zCam = transform.position.z;
     
     }
     
     void FixedUpdate () 
     {
             destination = new Vector3(xCam, player.position.y, zCam);
             currentPos = new Vector3(xCam, transform.position.y, zCam);
             transform.position = Vector3.SmoothDamp(currentPos, destination, ref velocity, dampTime);
     }
 }
