Classes
struct	systems::JoystickAxis
	Gamepad axis mapping configuration for look and move axes, used to support stick swapping in user settings. More...

Namespaces
namespace	systems
	Client-only input sampling system — split into two halves so mouse look can run every iterate() (smooth camera at any FPS) while movement keys run once per physics tick group (server-consistent).
namespace	systems::gamepad

Functions
JoystickAxis	systems::getLookJoystickAxes (bool swapSticks)
	Return the SDL axes used for camera look, honoring the stick-swap setting.
JoystickAxis	systems::getMoveJoystickAxes (bool swapSticks)
	Return the SDL axes used for movement, honoring the stick-swap setting.
bool	systems::gamepadConnected (SDL_Gamepad *gamepad)
	True when a gamepad handle is non-null and still connected.
std::uint8_t	systems::grenadeRadialIndexFromAim ()
	Convert the current grenade radial aim vector into a grenade slot index.
bool	systems::consumePendingGrenadeThrow ()
	Consume and clear the queued grenade quick-throw request.
void	systems::runMouseLook (Registry &registry, float mouseSensitivity, bool gravityFlipped=false)
	Sample mouse delta and accumulate into yaw / pitch.
void	systems::runMovementKeys (Registry &registry, const InputBindings &bindings, bool gravityFlipped=false)
	Sample keyboard state into the movement flags.
void	systems::runDeadInput (Registry &registry, const InputBindings &bindings)
	Sample skip-respawn input while the local player is dead.
void	systems::runWeaponKeys (Registry &registry, const InputBindings &bindings, float dt=0.0f)
	Sample keyboard state into the weapon flags.
void	systems::runInputSample (Registry &registry, const InputBindings &bindings, float mouseSensitivity=0.001f)
	Legacy combined sampler — calls both runMouseLook and runMovementKeys.
float	systems::gamepad::normaliseAxis (Sint16 raw, float deadzone=k_stickDeadzone)
	Convert SDL's int16 axis value to a deadzoned float in [-1, 1].
void	systems::runGamepadLook (Registry &registry, SDL_Gamepad *gamepad, float pitchSensitivity, float yawSensitivity, float deadzone, float dt, bool gravityFlipped=false, bool swapSticks=false)
	Sample the right stick into yaw / pitch.
void	systems::runGamepadMovement (Registry &registry, SDL_Gamepad *gamepad, const InputBindings &bindings, float deadzone, bool gravityFlipped=false, bool swapSticks=false)
	Sample gamepad buttons / left stick into the movement flags.
void	systems::runGamepadWeapon (Registry &registry, SDL_Gamepad *gamepad, const InputBindings &bindings)
	Sample gamepad buttons / right trigger into the weapon flags.
void	systems::runGamepadDeadInput (Registry &registry, SDL_Gamepad *gamepad, const InputBindings &bindings)
	Sample controller skip-respawn input while the local player is dead.

Variables
bool	systems::prevKillSelfKey = false
	Tracks previous-frame key state for edge detection.
bool	systems::prevGrenadeKey = false
	Tracks previous-frame G key state for grenade quick-throw / radial behavior.
float	systems::grenadeHeldSeconds = 0.0f
	Seconds the grenade key has been continuously held.
bool	systems::grenadeRadialActive = false
	True while the grenade radial selector is open.
glm::vec2	systems::grenadeRadialAim {0.0f, -1.0f}
	Current mouse-relative aim vector inside the grenade radial selector.
bool	systems::pendingGrenadeThrow = false
	Latched quick-throw request consumed by HUD/gameplay code.
constexpr float	systems::k_grenadeRadialHoldSeconds = 0.24f
	Hold duration before the grenade quick-throw becomes radial selection.
constexpr float	systems::k_grenadeRadialDeadzone = 18.0f
	Minimum radial aim distance required to choose a grenade slot.
constexpr float	systems::k_grenadeRadialMaxDistance = 130.0f
	Maximum stored cursor distance from the grenade radial center.
bool	systems::prevAbilitySelectLeft = false
	Tracks previous-frame Alt+LMB state for ability choice edge detection.
bool	systems::prevAbilitySelectRight = false
	Tracks previous-frame Alt+RMB state for ability choice edge detection.
bool	systems::prevGamepadAbilitySelectLeft = false
	Tracks previous-frame gamepad left ability-select chord for edge detection.
bool	systems::prevGamepadAbilitySelectRight = false
	Tracks previous-frame gamepad right ability-select chord for edge detection.
constexpr float	systems::gamepad::k_stickDeadzone = 0.15f
	Stick deadzone as a fraction of full deflection.
constexpr float	systems::gamepad::k_triggerThreshold = 0.5f
	Trigger threshold for treating an analog trigger as "pressed".
