There is also a [Java version](https://github.com/zachbarth/minimalist-game-framework-java) of this framework.\n\n# Getting Started #\n\n1. Clone the repo.\n2. Add your assets (images, fonts, sounds, and music) to the Assets folder. These files will be automatically synchronized to your build directory by a post-build step in Visual Studio.\n3. Start writing your game in the `Game` class.\n\nAll functions and properties listed below are members of the static `Engine` class. For example, if you wanted to draw a line, you could call `Engine.DrawLine()` from anywhere in your code.

Sometimes also called \"nine-patches\" or \"border textures\", these are textures that are divided into nine areas (specified at load time as numerical offsets from the edges) so that they can be drawn at different sizes without distorting the edges. The following example creates a resizable texture of a button and then draws it four times with different sizes:\n\n```C#\nResizableTexture button = Engine.LoadResizableTexture(\"button.png\", 20, 20, 20, 40);\nEngine.DrawResizableTexture(button, new Bounds2(10, 40, 50, 80));\nEngine.DrawResizableTexture(button, new Bounds2(70, 20, 100, 60));\nEngine.DrawResizableTexture(button, new Bounds2(180, 10, 70, 100));\nEngine.DrawResizableTexture(button, new Bounds2(260, 30, 120, 90));\n```\n\n![Resizable Textures Example](Docs/resizable-textures.png)\n" } ]
