Air nodes

This page uses Vector3 from Unity. The glossary says what each one is.

An air node is a waypoint on a drone’s route. Drones.Nodes() lists them so your mod can find a node id to send a drone to.

Drones the air nodes in the scene

Call Drones.Nodes() to list the air nodes in the scene, and pass a node’s Id to SetTarget.

public static class Drones
{
    public static List<AirNodeInfo> Nodes();
}

Method	Returns	What it does
`Nodes()`	`List<AirNodeInfo>`	Every air node in the scene you are in.

AirNodeInfo a snapshot of one air node

Drones.Nodes() gives you one of these for each node. LinkedNodeIds lists the nodes it connects to, in route order.

public sealed class AirNodeInfo
{
    public string Id { get; }
    public Vector3 Position { get; }
    public List<string> LinkedNodeIds { get; }
}

Property	Type	What it means
`Id`	`string`	Names this node. It is the same kind of id as `DroneInfo.Id`.
`Position`	`Vector3`	Where the node is, in world coordinates.
`LinkedNodeIds`	`List<string>`	The ids of the nodes this one links to, in route order.

Things to know

Nodes() only lists the nodes in the scene you are in, and you can’t change that. A node in another scene is not listed. (It uses FindObjectsByType, so inactive objects are left out.)
LinkedNodeIds lists every node this one links to, not just the one the drone will take next. A node with no links gives an empty list. (It is the full Air_Node.nextNodes list, with empty entries skipped. The node the game picks next depends on Air_Node.activeNodeIndex.)
The ids match the ones DroneInfo.TargetNodeId and SetTarget use. You can take an id from Nodes() and pass it straight to SetTarget.

You can’t change which nodes link to which. The links are set when the map is built, so to move a drone along a different route, send it to a node with SetTarget. (nextNodes is set in the Unity editor, and the framework has no node-link writer.)
