Get the offset value of the camera and the previous frame

Each layer of the background compensation movement of the speed of different, I the greater the speed of compensation will be greater

Float BACKGROUNDTARGETPOSX = backgrounds[i].position.x + Parallax * (i * parallaxreductionfactor + 1);

Y axis not moving

Vector3 Backgroundtargetpos = new Vector3 (BACKGROUNDTARGETPOSX, BACKGROUNDS[I].POSITION.Y, backgrounds[i].position.z );

Smooth movement

Backgrounds[i].position = Vector3.lerp (backgrounds[i].position, Backgroundtargetpos, smoothing * Time.deltaTime);

}

Update the position of the previous frame camera previouscampos = cam.position; } }
