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.

using UnityEngine;

// 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); } } }
