An ImGui.NET wrapper for Monogame

Monogame.ImGui

This is a Monogame wrapper for the ImGui.NET Library (https://github.com/mellinoe/ImGui.NET). Monogame.ImGui lets you build graphical interfaces for your Monogame games using a simple immediate-mode style.

Disclaimer: This code wasn't written by me, I just fixed a few things and uploaded it to a GitHub and NuGet. The code of the user I got it from: https://twitter.com/BinaryEyesDev

Usage

To use Monogame.ImGui, download this library using NuGet inside your Monogame project. In your Game1, Initialize ImGuiRenderer like so:

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using MonoGame.ImGui;



namespace YourGame
{
    public class Game1 : Game
    {
        public GraphicsDeviceManager graphics;
        SpriteBatch spriteBatch;

        public ImGUIRenderer GuiRenderer; //This is the ImGuiRenderer
    }
    
    protected override void Initialize()
    {
        GuiRenderer = new ImGUIRenderer(this).Initialize().RebuildFontAtlas();
        
        base.Initialize();
    }
...

And then in the Draw event, you need to add GuiRenderer.BeginLayout(gameTime); and GuiRenderer.EndLayout(); Like so:

...
protected override void Draw(GameTime gameTime)
{
    graphics.GraphicsDevice.Clear(Color.Coral);

    spriteBatch.Begin();
    //Your regular Game draw calls
    spriteBatch.End();

    base.Draw(gameTime);
    
    GuiRenderer.BeginLayout(gameTime);

    //Insert Your ImGui code

    GuiRenderer.EndLayout();

}
...

Dear ImGui is a bloat-free graphical user interface library for C++. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline enabled application. It is fast, portable, renderer agnostic and self-contained (no external dependencies).

Dear ImGui is designed to enable fast iterations and to empower programmers to create content creation tools and visualization / debug tools (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal, and lacks certain features normally found in more high-level libraries.

Dear ImGui is particularly suited to integration in games engine (for tooling), real-time 3D applications, fullscreen applications, embedded applications, or any applications on consoles platforms where operating system features are non-standard.
