camera_controller_first_person_euler

Mouse and keyboard control of a camera_first_person_euler (walk in a scene).

Derives from: camera_controller_generic_base

Fields and methods

Members of the struct camera_controller_first_person_euler. Most of what you do with a CGP type goes through the free functions listed below.

camera_first_person_euler camera_model Euler-angle first person camera driven by the controller.

`camera_generic_base const& camera() const` `camera_generic_base& camera()`	Returns camera_model as a read-only camera_generic_base. src
`void action_mouse_move()`	Updates the camera from the mouse displacement when the cursor is not on the GUI; left drag (or any move in cursor-captured mode) changes yaw and pitch, Ctrl + left drag twists axis_of_rotation, right drag moves forward/backward. src
`void set_rotation_axis(vec3 const& rotation_axis)`	Sets the axis_of_rotation (up direction when pitch = 0) of the camera. src
`void set_rotation_axis_x()`	Sets the axis_of_rotation of the camera to (1,0,0). src
`void set_rotation_axis_y()`	Sets the axis_of_rotation of the camera to (0,1,0). src
`void set_rotation_axis_z()`	Sets the axis_of_rotation of the camera to (0,0,1). src
`void action_keyboard()`	Toggles the cursor-captured mode with Shift+C (Escape releases the cursor). src
`void idle_frame()`	Moves the camera at 2 units per second while keys are held; W/S and up/down arrows forward/backward (Ctrl + up/down moves up/down), A/D and left/right sideways, R/F up/down, Q/E twist axis_of_rotation at 2 radians per second. src
`void look_at(vec3 const& eye, vec3 const& center, vec3 const& unused = vec3())`	Places the camera at eye looking toward center; the third argument is ignored (the up vector is set by axis_of_rotation). src
`std::string doc_usage() const`	Returns a text describing the mouse and keyboard controls of the Euler first person camera. src

Inherited from camera_controller_generic_base (5 members)

`bool is_active = true`	Enables the controller, true by default; when false the mouse and idle actions return without moving the camera.
`input_devices* inputs = nullptr`	Pointer to the global keyboard/mouse state, nullptr until initialize() is called.
`window_structure* window = nullptr`	Pointer to the global window state, nullptr until initialize() is called.

`void initialize(input_devices& inputs, window_structure& window)`	Stores pointers to the global inputs and window; must be called before any action function. src
`void action_mouse_click()`	Handles a mouse button press or release event; does nothing in the base class. src
