We had great craic at Dublin Gamecraft on Saturday 16th February 2024 creating games, music and art, and eating pizzas. Me and my long-time collaborator and great friend Darren Fitzpatrick created a pass-through MR game where you use a slingshot to pop alien-shaped balloons created by a weird, golden musical instrument powered by a hand crank. We used FOSS: Godot, Blender, Audacity and XR Toolkit and got most of the mechanics working within the time and everyone got to try it out! Looking forward to polishing our game and releasing it in the coming days! Godot is honestly a fantastic tool for XR prototyping. Huge thanks to TU Dublin Computer Science for sponsoring lunch and the pizzas and TU Dublin Chaplaincy for providing a beautiful and historic setting to inspire us!
