Detailed Description

Stores per-frame keyboard and mouse input state.

Owned by the Engine singleton. Game code reads state; only the Engine writes state (it is a friend). Arrays are sized for 512 keys and 16 mouse buttons, matching GLFW's key-code range.

)

const

Retrieve the cursor position for the current frame.

Subtract GetMousePositionOld() to get a per-frame delta suitable for camera rotation.

Returns

Screen-space cursor coordinates.
