Function cellAt

cellAt(
    shape: GridShape3D,
    x: number,
    z: number,
    tileSize?: number,
): { x: number; y: number }
The integer grid cell nearest world position (x, z) - the inverse of gridPoint3D. Nearest-cell rounding, not an exact point-in-hexagon test for the hex shape: consistent with rpg.Collision's own choice of simple axis sweeps over a full polygon solver, since every tile a capsule actually stands on is far larger than the rounding error near an edge.
Parameters
- shape: GridShape3D
- x: number
- z: number
- tileSize: number = 1
Returns { x: number; y: number }
Example
```
import { cellAt } from '@datamoc/mwg/3d';

console.log(cellAt('square', 3.4, 1.6, 2)); // { x: 2, y: 1 }
```
