protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); _spriteBatch.Begin(); knight.Draw(_spriteBatch); _spriteBatch.End(); base.Draw(gameTime); } } This example gives you a basic idea of creating a new entity (in this case, a knight) in a MonoGame project. For Hollow Knight, which is much more complex and uses a custom version of MonoGame, integrating directly would require deep knowledge of its codebase and potentially modifications to its source code.
