The camera primitive places the user somewhere within the scene. It is an entity that prescribes the camera component with mappings to controls-related components.
|Attribute||Component Mapping||Default Value|
To position the camera, set the position on a wrapper
<a-entity>. Don’t set the position directly on the camera primitive because controls will quickly override the set position:
When we use the camera primitive, A-Frame will not prescribe a default camera.
Note the default camera is positioned at
0 1.8 4 whereas the camera primitive will be positioned at
0 0 0. In the example below, we would see a box:
But if we prescribe our own camera and do not adjust its position:
Then both the cube and camera wll be positioned at
0 0 0, the camera will be inside the cube, and thus the box won’t be visible without moving the camera. So make sure the have the camera well-positioned.
We can use the look-at component to make another entity rotate towards the user:
Whenever the user (and thus the camera) moves, then the entity will update its rotation.
