Description
Base class for authoring data on a grid with grid painting tools like paint, erase, pick, select and fill.
Inheriting this class and/or creating brush asset instances from your inherited class, you can create custom brushes which react to high level grid events like paint, erase, pick, select and fill.

// Paints two prefabs in checkerboard pattern
[CreateAssetMenu]
public class CheckerboardBrush : GridBrushBase
{
public GameObject prefabA;
public GameObject prefabB;
public override void Paint(GridLayout grid, GameObject brushTarget, Vector3Int position)
{
bool evenCell = Mathf.Abs(position.y + position.x) % 2 > 0;
GameObject toBeInstantiated = evenCell ? prefabA : prefabB;
if (toBeInstantiated != null)
{
GameObject newInstance = Instantiate(toBeInstantiated, grid.CellToWorld(position), Quaternion.identity);
newInstance.transform.SetParent(brushTarget.transform);
}
}
