Member Function Documentation

◆ applyMouseMovement()

void CameraFPS::applyMouseMovement	(	float	x,
		float	y
	)

Applies mouse movement to the first person camera.

Parameters

x	The horizontal difference of the mouse position.
y	The vertical difference of the mouse position.

◆ update()

void CameraFPS::update ( float dt )

virtual

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

Parameters

dt	Time step.

Reimplemented from Camera.

Member Data Documentation

◆ m_attached

bool CameraFPS::m_attached

private

Attache the first person camera to a kart.

That means moving the kart also moves the camera.

◆ m_lin_velocity

core::vector3df CameraFPS::m_lin_velocity

private

Linear velocity of the camera, used for end and first person camera.

It's stored relative to the camera direction for the first person view.

◆ m_target_angular_velocity

float CameraFPS::m_target_angular_velocity

private

Target angular velocity.

Used for smooth movement in fps perpective.
