GridBrushBase

描述

用于使用网格绘制工具（如绘制、擦除、拾取、选择和填充）创建网格上数据的基类。

继承此类和/或从继承的类创建笔刷资产实例，您可以创建对高层网格事件（如绘制、擦除、拾取、选择和填充）做出反应的自定义笔刷。

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);
        }
    }
}
