// Simple Y-axis sorting void Update() spriteRenderer.sortingOrder = (int)(-transform.position.y * 100);

public float parallaxFactor = 0.5f; // lower = slower movement private Vector3 camStart; void Start() => camStart = Camera.main.transform.position;

void LateUpdate() transform.rotation = Quaternion.LookRotation(transform.position - Camera.main.transform.position); // Optional: lock rotation axes

void LateUpdate() Vector3 delta = Camera.main.transform.position - camStart; transform.position = new Vector3(transform.position.x + delta.x * parallaxFactor, transform.position.y + delta.y * parallaxFactor, transform.position.z);

Or use Unity's (Project Settings → Graphics → Set 2.5D Sorting Axis to (0,1,0) ). 3. Parallax Backgrounds Create a parallax layer controller:

Vector3 GetGridPosition(Vector3 worldPos) float tileSize = 1f; float x = (worldPos.x / tileSize + worldPos.z / tileSize) / 2; float z = (worldPos.z / tileSize - worldPos.x / tileSize) / 2; return new Vector3(Mathf.Round(x), 0, Mathf.Round(z));
