Detailed Description

Constructor & Destructor Documentation

◆ CameraNormal()

CameraNormal::CameraNormal	(	Camera::CameraType	type,
		int	camera_index,
		AbstractKart *	kart
	)

private

Constructor for the normal camera.

This is the only camera constructor except for the base class that takes a camera type as parameter. This is because debug and end camera use the normal camera as their base class.

Parameters

type	The type of the camera that is created (can be CM_TYPE_END or CM_TYPE_DEBUG).
camera_index	Index of this camera.
Kart	Pointer to the kart for which this camera is used.

Member Function Documentation

◆ getCameraSettings()

void CameraNormal::getCameraSettings	(	float *	above_kart,
		float *	cam_angle,
		float *	sideway,
		float *	distance,
		bool *	smoothing,
		float *	cam_roll_angle
	)

private

Determine the camera settings for the current frame.

Parameters

above_kart	How far above the camera should aim at.
cam_angle	Angle above the kart plane for the camera.
sideway	Sideway movement of the camera.
distance	Distance from kart.
cam_roll_angle	Roll camera for gyroscope steering effect.

◆ moveCamera()

void CameraNormal::moveCamera	(	float	dt,
		bool	smooth,
		float	cam_angle,
		float	distance
	)

private

Moves the camera smoothly from the current camera position (and target) to the new position and target.

Parameters

dt	Delta time,
if	false, the camera instantly moves to the endpoint, or else it smoothly moves

◆ positionCamera()

void CameraNormal::positionCamera	(	float	dt,
		float	above_kart,
		float	cam_angle,
		float	side_way,
		float	distance,
		float	smoothing,
		float	cam_roll_angle
	)

private

Actually sets the camera based on the given parameter.

Parameters

above_kart	How far above the camera should aim at.
cam_angle	Angle above the kart plane for the camera.
sideway	Sideway movement of the camera.
distance	Distance from kart.
cam_roll_angle	Roll camera for gyroscope steering effect.

◆ update()

void CameraNormal::update ( float dt )

virtual

Called once per time frame to move the camera to the right position.

Parameters

dt	Time step.

Reimplemented from Camera.

Reimplemented in CameraDebug, and CameraEnd.
