Member Function Documentation

◆ ControllerAxisPivotValImpl()

float Karma::LinuxInput::ControllerAxisPivotValImpl	(	int	axis,
		int	cID )

overrideprotectedvirtual

Linux implementation of ControllerAxisPivotVal function.

Parameters

axis	The horizontal/vertical directional deflection of the axis (GLFW axes). GLFW_GAMEPAD_AXIS_LEFT_Y is an example.
cID	The ID of the attached controller, defined in GLFW

Since: Karma 1.0.0

Implements Karma::Input.

◆ GetMousePositionImpl()
