+# Respin View
+
+## Overview
+
+* The `RespinView` class is responsible for the presentation layer of the respin feature. It extends the core `View` component and can be customized to display visual feedback related to respins.
+
+## Description:
+
+* Initializes a new instance of RespinView.
+* Calls the base View constructor.
+* [p4f-slotty-core/src/view/respin-view.js#L5](https://gitea.plp19.com/cocos-core/p4f-slotty-core/src/commit/7fbf58bf2ad8edec4258757b353151b638c96652/src/view/respin-view.js#L5) |
