UI要素をScriptから作成

2019.01.23
Unity
script, UI

　Scriptでゲームオブジェクトを作成し、そのオブジェクトに必要なコンポーネントを追加することで、新たにUI要素を作成します。しかし、この方法でUI要素を作成すると、デフォルトの画像を使用する際に問題が生じます。Editorで実行する場合に限れば以下のコードからデフォルトの画像を取得できます。

UnityEditor.AssetDatabase.GetBuiltinExtraResource<Sprite>("ファイルパス");

1	UnityEditor.AssetDatabase.GetBuiltinExtraResource<Sprite>("ファイルパス");

当然、Build後には使用できません。そのため、public変数を用意した後にInspectorからデフォルトの画像を指定し、その変数を用いてUI要素に画像を設定する必要があります。以下に掲載されているScriptでは、Editorで実行する場合はUnityのリソースから、Build後は変数に入れられている画像を使用します。

1. Canvas
2. Text
3. Image
4. RawImage
5. Button
6. Toggle
7. Slider
8. Scrollbar
9. Dropdown
10. InputField
11. Panel
12. Scroll View
13. 全てまとめたScript
