Detailed Description

Aggregates multiple physical inputs into logical actions.

Allows binding several keys/buttons/axes to one logical name. Booleans are OR‑combined, axes keep the highest absolute value, vector inputs overwrite.

Member Function Documentation

BindInput()

void InputSystem::BindInput	(	const std::string &	name,
		const Input &	input )

Adds an input to a logical binding.

Parameters

name	Logical action name.
input	Input description (device, key, type).

Multiple inputs can be bound to the same name.

GetBoolInput()

std::optional< bool > InputSystem::GetBoolInput

(

const std::string &

name

)

Returns the boolean state of a logical binding.

Parameters

name	Action name.

Returns

std::nullopt if binding does not exist, otherwise the current boolean state.

GetNumberInput()

std::optional< float > InputSystem::GetNumberInput

(

const std::string &

name

)

Returns the float axis state of a logical binding.

Parameters

name	Action name.

Returns

std::nullopt if binding does not exist, otherwise the current axis value.

GetVectorInput()

std::optional< Vec2< float > > InputSystem::GetVectorInput

(

const std::string &

name

)

Returns the vector (position/delta) state of a logical binding.

Parameters

name	Action name.

Returns

std::nullopt if binding does not exist, otherwise the current vector.

SetScaling()

void InputSystem::SetScaling	(	const float	scale,
		const Vec2< float >	offset )

Sets mouse scaling and offset for POSITION/DELTA queries.

Parameters

scale	Scale factor applied to mouse coordinates.
offset	Pixel offset added before scaling.

UnbindInput()

void InputSystem::UnbindInput

(

const std::string &

name

)

Removes a logical binding entirely.

Parameters

name	Action name.

Update()

void InputSystem::Update ( const float deltaT )

overridevirtual

Updates all input states.

Parameters

deltaT

Time since last update (unused).

Reads current mouse position (scaled), then evaluates every bound input and aggregates the results into per‑name InputState structures.

Implements System.
