A Wii Remote interface for Godot4 using GDExtension.

This is based on the godot-cpp template, a quickstart template for GDExtension development with Godot 4.0+.

This project targets the latest verison of godot (4.1).

This repository was primarily created to perform wii remote head tracking using IR data from a static wii remote. While supporting additional functions of the wiimote are preferred, I am not familiar enough with godot to know what the best way to do this is - contributions are absolutely welcome!

• An Godot project for demonstrating the functionality (demo/)
• godot-cpp as a submodule (godot-cpp/) to integrate with the WiiUse C++ library
• GitHub CI/CD confirm build functionality and upload library packages when creating a release (.github/workflows/builds.yml)
• source code for C++ GDExtension (src/)

In order to build, you must ensure dependencies are installed/available on your system.

Ensure the WiiUse library is installed in a location that can be found by your system

Wiiuse may also depend on additional things based on your platform, see the wiiuse README for more detailed, platform-specific instructions.

git clone https://github.com/wiiuse/wiiuse.git
cd wiiuse
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -DBUILD_EXAMPLE_SDL=NO -DBUILD_SHARED_LIBS=TRUE
make wiiuse
sudo make install

see unix instructions, except use the following cmake command if you want support for universal binaries (for both intel and Apple Silicon macs): cmake .. -DCMAKE_BUILD_TYPE=Release -DBUILD_EXAMPLE_SDL=NO -DBUILD_SHARED_LIBS=TRUE "-DCMAKE_OSX_ARCHITECTURES=x86_64;arm64"

The build process should be realtively straghtforward since this project adheres to the typical GDExtension convention of using scons as a build system. For most platforms, the build process should just involve running the scons command.

To add the extension to a godot 4.1+ project, open the project and import the .zip file [TBD, see #6] or the .gdextension file using the import button on the AssetLib tab of Godot.

A minimal example of how to use the extension can be found in the demo directory

When you start the demo by pressing the play button you will see the godot engine logo for longer than you may be used to (about 5 seconds) - as soon as you see this, hit the 1+2 buttons on your wii remote to make it discoverable. If it successfully discovers and connects to your remote, youll get a little vibration/buzz (like a real wii does) and the player 1 light on the wiimote will turn on.

If you successfully connect to a wiimote, then it should be looking for IR sensor data (such as from the sensor bar, or really any two IR sources spaced about that far apart - two candles may work in a pinch) to change the position of the camera (like Johnny Lee's wiimote head tracking demo)
