Tilemap.GetCellCenterWorld

Parameters

Returns

Vector3 Center of the cell transformed into world space coordinates.

Description

Get the logical center coordinate of a Grid cell in world space.

In a rectangular grid layout, a call to GridLayout.CellToWorld with Vector3Int parameter, returns a Vector3 coordinate that represents the bottom-left of the cell. This is mathematically correct, but when for example instantiating a GameObject into the grid, you prefer the center of the cell instead.

// Snap the GameObject to parent Tilemap center of cell
using UnityEngine;
using UnityEngine.Tilemaps;

public class ExampleClass : MonoBehaviour
{
    void Start()
    {
        Tilemap tilemap = transform.parent.GetComponent<Tilemap>();
        Vector3Int cellPosition = tilemap.WorldToCell(transform.position);
        transform.position = tilemap.GetCellCenterWorld(cellPosition);
    }
}
