Toolkit — 2.5d

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));

public float parallaxFactor = 0.5f; // lower = slower movement private Vector3 camStart; void Start() => camStart = Camera.main.transform.position; 2.5d toolkit

Or use Unity's (Project Settings → Graphics → Set 2.5D Sorting Axis to (0,1,0) ). 3. Parallax Backgrounds Create a parallax layer controller: return new Vector3(Mathf.Round(x)

Convert mouse click to 2.5D grid cell:

For trees, particles, or UI labels:

// Simple Y-axis sorting void Update() spriteRenderer.sortingOrder = (int)(-transform.position.y * 100); public float parallaxFactor = 0.5f
