Camera

Open 3D Engine (O3DE), the successor to Lumberyard, is now available in Developer Preview. Download O3DE or visit the AWS Game Tech blog to learn more.

The Camera component allows an entity to be used as a camera. To use the Camera component, you must first add a Camera Framework gem to your project. For information, see Camera Framework Gem.

Camera Component Properties

The Camera component has the following properties:

Name	Description

Near clip distance	Distance to the near clip plane of the view frustum in meters. Default value: 0.2
Far clip distance	Distance to the near far plane of the view frustum in meters. Default value: 1024
Be this camera	Editor uses the selected camera as its view. For more information, see Changing the Camera View.

EBus Request Bus Interface

Use the following request functions with the event bus (EBus) interface, CameraRequestBus, to communicate with other components of your game.

For more information, see Working with the Event Bus (EBus) system.

Request Name	Description
GetFov	Gets the current field of view.
SetFov	Sets the current field of view.
GetNearClipDistance	Gets the current near clip distance.
SetNearClipDistance	Sets the current near clip distance.
GetFarClipDistance	Gets the current far clip distance.
SetFarClipDistance	Sets the current far clip distance.

The following is an example of script using the Request Bus Interface.

local camerasample =
{
    Properties =
    {
    }
}
 
function camerasample:OnActivate()
    CameraRequestBus.Event.SetFov(self.entityId, 85)
    local nearClip = CameraRequestBus.Event.GetNearClipDistance(self.entityId)
    CameraRequestBus.Event.SetFarClipDistance(self.entityId, nearClip + 1024)
end
 
return camerasample

Creating Camera Entity from View

You can create a static camera view from a specific entity by right-clicking an entity in the viewport and choosing Create camera entity from view. This places a new entity with a camera component at the same point. You can adjust the view of the camera by modifying its transform component.
