Detailed Description

The Camera class represents a camera in the game world.

Represents a camera component that can be attached to a game object.

Constructor & Destructor Documentation

Camera()

Camera::Camera

(

GameObject *

go

)

Constructor for the Camera class.

Parameters

go	The game object to attach the camera to.

Member Function Documentation

Capture()

void Camera::Capture

(

)

Captures the camera.

Captures current scene (see currentScene variable in Scene class)

ChangeOrtho()

void Camera::ChangeOrtho	(	float	sizeX,
		float	sizeY )

Changes the orthographic size of the camera.

Parameters

sizeX	The new size along the X-axis.
sizeY	The new size along the Y-axis.

Deserialize()

int Camera::Deserialize ( std::fstream * data, int offset )

overridevirtual

Deserialize the object from the file.

Parameters

data	The file stream to read the serialized data from.
offset	The offset in the file to start reading the serialized data.

Returns

The number of bytes read from the file, or -1 if an error occurred.

Reimplemented from Serialized.

GetType()

static std::string Camera::GetType ( )

inlinestatic

Gets the type of the camera.

Returns

The type of the camera.

MoveTo()

void Camera::MoveTo	(	Vector2< int >	target,
		float	interpolationTime )

Moves the camera to the target position with interpolation.

Parameters

target	The target position to move the camera to.
interpolationTime	The time taken for the interpolation.

Serialize()

int Camera::Serialize ( std::fstream * data, int offset )

overridevirtual

Serialize the object and write it to the file.

Parameters

data	The file stream to write the serialized data to.
offset	The offset in the file to start writing the serialized data.

Returns

The number of bytes written to the file, or -1 if an error occurred.

Reimplemented from Serialized.

Update()

void Camera::Update ( )

virtual

Updates the camera.

Reimplemented from GameComponent.

UpdateActiveCamera()

void Camera::UpdateActiveCamera ( )

static

Updates the active camera.

This static method calls capture on ActiveCamera if not null.
