Function Documentation

GetAxisDirection()

u8 rex::hid::GetAxisDirection ( u8 axis_slot )

constexpr

Returns the direction of a stick row slot, 0 to kAxisDirections - 1.

Parameters

axis_slot

A 1 based slot from InputSource::axis_slot.

GetAxisSlot()

u8 rex::hid::GetAxisSlot ( u8 direction, u8 alternate )

constexpr

Returns the stick row slot of a key half. The slot is 1 based, to store in InputSource::axis_slot.

Parameters

direction	The direction, 0 to kAxisDirections - 1.
alternate	Which key of the direction, 0 for the first and 1 for the second.

GetBindableKeys()

REX_HID_API std::span< const VirtualKey > rex::hid::GetBindableKeys

(

)

Returns the keys and mouse buttons a binding can name, in ascending VirtualKey order. Modifier keys are not listed.
