How can I fix the camera jitter issue caused by physics updates in my game’s engine?

Fixing Camera Jitter Caused by Physics Updates in Unity

Camera jitter is a common issue in games that arises due to discrepancies between camera updates and physics calculations. In Unity, there are several strategies to address this:

1. Smooth Camera Movement

• Interpolate Camera Position: Use interpolation techniques to ensure smoother camera transitions. Implement this by lerping between the camera’s current and target positions.
• FixedUpdate synchronization: Align your camera updates with physics updates by moving your camera logic to the FixedUpdate() method, which is synced with physics calculations.

2. Physics Settings Adjustments

• Physics Time Step: Increase the physics time step value in the Unity editor under Edit > Project Settings > Time to reduce the frequency of state updates, thereby mitigating jitter.

3. Rigging and Animation Improvements

• Cinemachine: If you’re using Cinemachine, ensure to check the update method. Set it to LateUpdate or configure it to use a custom blend for smooth transitions.

4. Code Enhancement

public class CameraFollow : MonoBehaviour { public Transform target; public float smoothSpeed = 0.125f; public Vector3 offset; void FixedUpdate() { Vector3 desiredPosition = target.position + offset; Vector3 smoothedPosition = Vector3.Lerp(transform.position, desiredPosition, smoothSpeed); transform.position = smoothedPosition; } }

Use this script snippet to implement a basic camera follow system with smoothing to reduce jitter effects.
