What is playsmart-unity-uitoolkit-extensions?

Playsmart UI Toolkit Extensions is a small code library for Unity, the game engine, that adds a couple of missing features to Unity's UI Toolkit system for building game interfaces. It focuses on two things: spacing between elements and slanted shapes. The first feature, called Gap, solves a common annoyance. Unity's UI Toolkit does not support the gap property that web developers use to add even spacing between items in a row or column. This library brings that spacing back in a way that automatically works whether the container arranges its items horizontally or vertically, and it keeps layouts clean by making sure the last item in a list does not get an extra bit of spacing it does not need. The second feature, called Skew, lets a developer draw slanted, parallelogram shaped panels and buttons instead of plain rectangles, a look often used in game menus and sports style interfaces. You can control the angle and size of the slant, the fill color, and the border color and width. There is also a SkewButton, a clickable version of the shape that behaves like a normal Unity button but registers clicks accurately even though its edges are angled rather than straight. Both features work through custom style properties written directly in Unity's USS stylesheets, similar to how CSS works on a website, so a programmer sets things up once and a designer can then adjust spacing, angles, and colors without touching any code. Installing the library happens through Unity's Package Manager by adding it from a Git URL, so no manual file copying is needed. Once installed, the new elements can be used directly inside Unity's UXML markup files alongside standard UI Toolkit elements. The project is written in C# and is released under the MIT license, meaning it can be used freely, including in commercial games, as long as the copyright notice is kept.
