Integrate imgui_bundle with the Blender Game Engine (and variants) Currently works with RanGE engine, UPBGE 0.2.5, and UPBGE 0.4+.
To use in your game, simply add the my_game folder alongside your game blend. Not much documentation, but there are some comments in the python scripts and some example files to help you.
⚠ NOTE FOR UPBGE USERS: If you are using the new Eevee-next renderer, in-game texture UI elements are not supported because the
bge.texturemodule is broken. ⚠ The newgpumodule is the alternative, however it is feature-incomplete and lacks working documentation for rendering to textures. If you can find better documentation, please let me know and I can add a fix. Full-screen UI elements still work fine in Eevee-next AFAIK
To make a custom GUI for your game, extend BGEImguiWrapper class and
override the setup_gui() and draw() methods.
An example is shown in my_gui.py, and a usage example in main.py.
If you just want a simple example for how to use imgui_bundle/pyimgui, refer to
simple.py.
For both UPBGE and RanGE, the example's logic bricks look roughly like this:
But you can of course use Python Components or scripts however you want. By default, the BGEImguiWrapper stores the instance of itself in bge.logic.gui to make it easy to access from other scripts.
In order to set up imgui_bundle to work correctly in your game, there are a few steps involved.
First, you'll need to install imgui_bundle and a few other libraries into the engine's python install.

Next, read simple_gui.py and simple.py to see how to make your own GUI class and run it in-game.
