[ONLY WORKS ON WINDOWS] This is Input Overlay On Love2D, Allowing To Show Advanced Animations on Input Overlay! The Only Limit is Imagination!
Copy Love2d, then rename to something else. Run The Command (3 button for example):
(path to your cloned and renamed love2d executable) (path to input overlay) --3btn
On OBS, Add The Game capture and Set the Mode "Capture specific window", then on Window, find "[your cloned and renamed love2d executable]: (null)" and click on it. Disable "Use anti-cheat compatibility hook", This Thing does not use anti-cheat! Also, Allow Transparency. This Window Supports Transparency, just not visible on viewing thing. Adjust to your liking, and You are Done!
