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.
bool	systems::consumePendingGrenadeThrow ()
	Consume and clear the queued grenade throw request.
bool	systems::consumePendingGrenadeCycleNext ()
	Consume and clear the queued "cycle to next grenade" request.
bool	systems::consumePendingGrenadeCyclePrev ()
	Consume and clear the queued "cycle to previous grenade" request.
bool	systems::consumePendingGamepadWeaponSwap ()
	Consume and clear the latched tap-Y gamepad weapon swap request.
int	systems::consumePendingEmote ()
	Consume and clear the latched emote-play request (-1 = none).
bool	systems::consumePendingAbilitySelectLeft ()
	Consume and clear the queued left ability-choice request.
bool	systems::consumePendingAbilitySelectRight ()
	Consume and clear the queued right ability-choice request.
void	systems::emoteWheelApplyPointing (float dx, float dy, bool accumulate)
	Resolve emoteWheelSelection from a pointing input.
void	systems::runEmoteWheelKey (const InputBindings &bindings)
	Track the Emote binding (keyboard/mouse) to open/close the wheel.
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)
	Sample keyboard state into the weapon flags.
void	systems::runInputSample (Registry &registry, const InputBindings &bindings, float mouseSensitivity=user_settings::kDefaultMouseSensitivity)
	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::runGamepadEmoteWheel (SDL_Gamepad *gamepad, const InputBindings &bindings, bool swapSticks=false)
	Track the Emote binding (controller) to open/close the wheel and pick a sector from the right stick.
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::prevGrenadeCycleKey = false
	Previous-frame CycleGrenade (H) / ThrowGrenade (G) key state for edge detection (keyboard/mouse).
bool	systems::prevGrenadeThrowKey = false
bool	systems::prevGamepadGrenadeCycleKey = false
	Gamepad equivalents: CycleGrenade (D-pad Left) / ThrowGrenade (B).
bool	systems::prevGamepadGrenadeThrowKey = false
bool	systems::pendingGrenadeThrow = false
	Latched throw request, consumed once per frame by the game loop.
bool	systems::pendingGrenadeCycleNext = false
	Latched cycle next/prev requests, consumed once per frame by the game loop.
bool	systems::pendingGrenadeCyclePrev = false
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::pendingAbilitySelectLeft = false
	Latched ability choice requests, consumed once per sent input batch.
bool	systems::pendingAbilitySelectRight = false
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.
bool	systems::prevGamepadPickupKey = false
	Gamepad Y (Pickup binding) tap-vs-hold state: tap swaps weapon, hold picks up.
Uint64	systems::gamepadPickupDownMs = 0
	SDL_GetTicks at the Y press, for hold-duration timing.
bool	systems::gamepadPickupHoldFired = false
	Set once the press crossed the hold threshold (suppresses tap-swap).
bool	systems::pendingGamepadWeaponSwap = false
	Latched tap-Y weapon swap, consumed once per frame by the game loop.
float	systems::gamepadLookAccel = 0.0f
	COD-style look acceleration progress in [0, 1]; ramps while the look stick is held near full deflection and resets when it eases off.
bool	systems::emoteWheelOpen = false
	True while the emote wheel is open (Emote binding held on any device).
int	systems::emoteWheelSelection = -1
	Currently highlighted emote sector while the wheel is open, or -1 (none).
