スクリプタブル ブラシ

スクリプタブルブラシの作成

Create a new class inheriting from GridBrushBase (or any useful subclasses of GridBrushBase like GridBrush). Override any required methods for your new Brush class. The following are the usual methods you would override:

  • Paint allows the Brush to add items onto the target Grid.
  • Erase allows the Brush to remove items from the target Grid.
  • FloodFill allows the Brush to fill items onto the target Grid.
  • Rotate ― ブラシ内に設定されたアイテムを回転させます。
  • Flip ― ブラシ内に設定されたアイテムをフリップします。

ScriptableObject.CreateInstance<(Your Brush Class>() を使用して、新しく作成したクラスのインスタンスを作成してください。 AssetDatabase.CreateAsset() を呼び出せば、この新しいインスタンスをエディター内でアセットに変換でき、繰り返し使用することができるようになります。

ブラシ用にカスタムエディターを作成することもできます。これは、スクリプタブル オブジェクト用のカスタムエディターと同じように機能します。カスタムエディターを作成する場合にオーバーライドするメソッドの主要なものは以下の通りです。

  • You can override OnPaintInspectorGUI to have an Inspector window appear on the Palette when the Brush is selected to provide additional behaviour when painting.
  • You can also override OnPaintSceneGUI to add additional behaviours when painting on the SceneView.
  • You can also override validTargets to have a custom list of targets which the Brush can interact with. This list of targets is shown as a dropdown list in the Palette window.

When created, the Scriptable Brush is listed in the Brushes dropdown menu in the Palette window. By default, an instance of the Scriptable Brush script is instantiated and stored in the Library folder of your project. Any modifications to the brush properties are stored in that instance. If you want to have multiple copies of that Brush with different properties, you can instantiate the Brush as Assets in your project. These Brush Assets are listed separately in the Brush dropdown menu.

You can add a CustomGridBrush attribute to your Scriptable Brush class. This allows you to configure the behavior of the Brush in the Palette window. The CustomGridBrush attribute has the following properties:

  • HideAssetInstances - Set this to true to hide all copies of created Brush Assets in the Palette window. This is useful when you want only the default instance to show up in the Brush dropdown menu in the Tile Palette window.
  • HideDefaultInstances - Set this to true to hide the default instance of the Brush in the Palette window. This is useful when you want only created Assets to show up in the Brush dropdown menu in the Tile Palette window.
  • DefaultBrush - Set this to true to set the default instance of the Brush as the default Brush in the project. This makes this Brush the default selected Brush whenever the project starts. Note: Only set one Scriptable Brush as the Default Brush. Setting more than one Default Brush may cause your Scriptable Brushes to behave incorrectly.
  • DefaultName - Set a name to this to have the Brush dropdown menu use the set name as the name for the Brush instead of the name of the Brush’s class.

If you want your Scriptable Brush class to use only certain tools, you can add a BrushTools attribute to your class with a list of compatible TilemapEditorTools types. This ensures that your Scriptable Brush only activates with these specific tools from the Tile Palette toolbar.

Note: Remember to save your project to ensure that your new Brush Assets are saved!
