Sprite jitter in 2.5D projects often stems from inconsistent handling of physics-driven movement. To address this, it is crucial to delegate all movement updates for objects managed by the physics engine exclusively to the Rigidbody2D API.

1. Configure the Rigidbody2D component by setting the interpolation mode to Interpolate. This ensures the visual representation remains smooth between physics calculation steps.
2. Transition all movement logic from Transform.position to Rigidbody2D.MovePosition or Rigidbody2D.velocity. Directly modifying the transform bypasses the physics solver and breaks interpolation.
3. Ensure that your character controller scripts are not resetting the localPosition of the child sprite object every frame, as this overrides physical smoothing.
4. Access position data through the Rigidbody2D.position property instead of the Transform, as the former is synchronized with the interpolation state.

If these guidelines are adhered to, physics-related inconsistencies are less likely to be the root cause of the jitter.

Beyond physics considerations, it is imperative to meticulously review all associated scripts, especially those interacting with collisions. Unintended side effects can arise from scripts that dynamically add components (such as colliders) or activate specific logic immediately following a collision. Such actions can introduce unexpected modifications to an object’s state or hierarchy, leading to visual instability.

For a systematic debugging approach, consider incrementally removing elements from the scene, starting with your character controller scripts, until the jitter ceases, thereby isolating the problematic component.

Additional Tips

• Set your Camera follow logic to LateUpdate to ensure it targets the final calculated position of the sprite after interpolation.
• Avoid adding or removing Collider2D components at runtime during collisions; instead, use the enabled property or layers to manage state without forcing a physics rebuild.
• If using the Pixel Perfect package, verify that Upscale Render Texture is enabled to minimize snapping artifacts during interpolation.
