One of the only functions I could think of that would fit the name and structure is one that handles the cocking of a gun. I know that Godot is primarily for 2D games, and Hotline Miami-likes are the most common 2D shooters I've been seeing recently.
Is it dynamically typed tho?
Its missing the return type of the function (which i left out because its only there to be called from a signal so it doesnt matter too much & because the Godot editor didn't bother adding it when it inserted the function to receive the signal).
But otherwise its already statically typed right?
(COCK is a constant in the script that i did give a type and stream and play() are part of the AudioStreamPlayer3D node)
