MonoGeometry is a simple, low impact primitive drawing add-on for the Monogame game engine. It provides a collection of options for drawing simple shapes to the screen, which is a feature that's a bit verbose to achieve normally.

It also provides structures for handling simple 2D shapes that aren't present in Monogame by default, like triangles and circles.

In the future, this project will be expanded with more shape structures, and more options for drawing simple primitives.

MonoGeometry can be installed throught the NuGet package manager, with the following command:

dotnet add package MonoGeometry --version 1.0.1

This package's NuGet page is available here.

The basis of MonoGeometry is the PrimitiveBatch class. Its usage is much the same as the SpriteBatch class provided by default.

Create a private PrimitiveBatch instance, and initialize it in the LoadContent method:

private PrimitiveBatch _primitiveBatch;

protected override void LoadContent()
{
  this.Content.RootDirectory = "Content";
  this._primitiveBatch = new(this.GraphicsDevice);
}

Primitives can now be drawn to the screen in the Draw method, with the same begin and end syntax as SpriteBatch:

protected override void Draw(GameTime gameTime)
{
  this._primitiveBatch.Begin();
  this._primitiveBatch.FillColor = Color.Black;
  //Draw a circle with center coordinates (100, 100) and a radius of 5
  this._primitiveBatch.Circle(new Vector2(100, 100), 5);
  this._primitiveBatch.End();
  base.Draw(gameTime);
}
