Camera Types

The Untold Engine provides several types of camera, such as a First Person Camera, Third Person Camera and a Basic Follow Camera.

Third Person Camera

To implement a Third Person Camera, you need to create Camera of type U4DEngine::U4DCameraThirdPerson (line 1) and set its parameters using the method U4DEngine::U4DCameraThirdPerson::setParameters() as shown in line 2. The parameters determine the offset position between the camera and the target 3D model. Once the Camera Type has been created, you attach the behavior to the Camera object as shown in line 3.

//Instantiate the camera
U4DEngine::U4DCamera *camera=U4DEngine::U4DCamera::sharedInstance();

//Line 1. Instantiate the camera interface and the type of camera you desire
U4DEngine::U4DCameraInterface *cameraThirdPerson=U4DEngine::U4DCameraThirdPerson::sharedInstance();

//Line 2. Set the parameters for the camera. Such as which model the camera will target, and the offset positions
cameraThirdPerson->setParameters(astronaut,0.0,5.0,10.0);

//Line 3. set the camera behavior
camera->setCameraBehavior(cameraThirdPerson);

The Untold Engine will create a Third Person camera as shown below:

First Person Camera

To implement a First Person Camera, you need to create Camera of type U4DEngine::U4DCameraFirstPerson (line 1) and set its parameters using the method U4DEngine::U4DCameraFirstPerson::setParameters() as shown in line 2. The parameters determine the offset position between the camera and the target 3D model.

Once the Camera Type has been created, you attach the behavior to the Camera object as shown in line 3.

Note that the z-offset position represents the z-axis distance in front of the target 3D model.

//Instantiate the camera
U4DEngine::U4DCamera *camera=U4DEngine::U4DCamera::sharedInstance();
                    
//Line 1. Instantiate the camera interface and the type of camera you desire
U4DEngine::U4DCameraInterface *cameraFirstPerson=U4DEngine::U4DCameraFirstPerson::sharedInstance();

//Line 2. Set the parameters for the camera. Such as which model the camera will target, and the offset positions
cameraFirstPerson->setParameters(astronaut,0.0,0.5,0.5);

//Line 3. set the camera behavior
camera->setCameraBehavior(cameraFirstPerson);

The Untold Engine will create a First Person camera as shown below:

Basic Follow

To implement a Third Person Camera, you need to create Camera of type U4DEngine::U4DCameraBasicFollow (line 1) and set its parameters using the method U4DEngine::U4DCameraBasicFollow::setParameters() as shown in line 2. The parameters determine the offset position between the camera and the target 3D model.

Once the Camera Type has been created, you attach the behavior to the Camera object as shown in line 3.

Note that the Basic Follow Camera does not rotate whenever the target 3D model rotates. It only follows it across the screen.

//Instantiate the camera
U4DEngine::U4DCamera *camera=U4DEngine::U4DCamera::sharedInstance();
                   
//Instantiate the camera interface and the type of camera you desire
U4DEngine::U4DCameraInterface *cameraBasicFollow=U4DEngine::U4DCameraBasicFollow::sharedInstance();

//Set the parameters for the camera. Such as which model the camera will target, and the offset positions
cameraBasicFollow->setParameters(astronaut,0.0,5.0,-10.0);

//set the camera behavior
camera->setCameraBehavior(cameraBasicFollow);

The Untold Engine will create a Basic Follow camera as shown below:
