Enum CameraFollow 

pub enum CameraFollow {
    Node {
        id: NodeId,
        offset: Vec3,
        look_at: bool,
    },
    Free,
}

Camera tracking mode for super::ViewportRuntime.

When set, the runtime computes a suggested camera center after each step and emits it as a super::CameraFollowTarget event on super::RuntimeOutput::events. The app reads the event by calling output.events.read::<CameraFollowTarget>() and applies the suggestion however fits the application (typically by setting camera.center).

Set via super::ViewportRuntime::set_camera_follow or super::ViewportRuntime::with_camera_follow.

Variants

Node

Track a scene node.

The suggested center is node_world_pos + offset. Orbit camera distance and orientation are unaffected; the camera pivots around the moving target.

Fields

id: NodeId

Node to follow.

offset: Vec3

World-space offset added to the node’s position.

look_at: bool

Unused by the runtime itself. Apps may use it to decide whether to orient the camera toward the node.

Free

No tracking. The runtime does not emit CameraFollowTarget.
