Member Function Documentation

GetCam2D()

Camera * CameraManager::GetCam2D ( )

private

Retrieval of current 2D camera.

This function retrieves the 2D camera, for uses such as rendering sprites.

Returns

Camera*

GetCurrCam()

Camera * CameraManager::GetCurrCam ( )

private

Retrieval of current camera.

This function retrieves the current active camera, for uses such as rendering models.

Returns

Camera*

MoveCam()

void CameraManager::MoveCam ( Vect up, Vect lookAt, Vect pos )

private

Moves main camera and changes orientation.

This function is set up to allow users to change where the camera is located as well as what the camera is facing. This does not automatically call UpdateCam().

Parameters

up
lookAt
pos

SetCurrCam()

void CameraManager::SetCurrCam ( Camera * newCam )

private

Swaps main Camera.

Allows for the current active camera to be swapped with a user generated camera. Users are now responsible for deletion of the new camera.

Warning

NearClipPlane, FarClipPlane, and FOV must be set to do screen picking

Example:

Camera* tmpCam = new Camera(Camera::Type::PERSPECTIVE_3D);
tmpCam->setViewport(0, 0, Game::GetWidth(), Game::GetHeight());
tmpCam->setPerspective(35.0f, float(Game::GetWidth()) / float(Game::GetHeight()), 1.0f, 5000.0f);
 
// Orient Camera
Vect up3DCam(0.0f, 1.0f, 0.0f);
Vect pos3DCam(50.0f, 50.0f, 150.0f);
Vect lookAt3DCam(0.0f, 0.0f, 0.0f);
 
SceneManager::GetCurrScene()->SetCurrCam(tmpCam);
SceneManager::GetCurrScene()->MoveCam(up3DCam, lookAt3DCam, pos3DCam);
SceneManager::GetCurrScene()->UpdateCam();
 
//THESE MUST BE SET FOR SCREEN PICKING
SceneManager::GetCurrScene()->setNearClipPlane(1.0f);
SceneManager::GetCurrScene()->setFarClipPlane(5000.0f);
SceneManager::GetCurrScene()->setFOV(35.0f);

Parameters

newCam

UpdateCam()

void CameraManager::UpdateCam ( )

private

Responsible for updating the main camera.

Allows changes made by MoveCam() to take effect within the scene.
