How to add a custom node
- Create a class library.
- Add the usual UnityEngine and Assembly-CSharp references
- Add a reference to KSPComputer.dll
- Inherit from one of the following classes (Namespace: KSPComputer.Nodes):
- Node: Data node, no execution. Provides data in OnUpdateOutputData()
- RootNode: A node without an incoming execution connector. Base class for "Event-Type" nodes. Needs to call "Execute()" on itself
- ExecutableNode: A node which will be executed via an incoming connector and has at least one outgoing connector. Create executable nodes via In/Out<Connector.Exec>("Name", true/false); (true/false -> for exec connectors, multiple outputs is reverted)
- When done, create an json file, named after your node, including the namespace. E.g. "MyNodeNamespace.NodeMyNode.json"
- Place the .dll in the Plugins folder and the node xml in one of the category folders (or create your own category)
- Your node MUST be [Serializable]
- Done
Node syntax overview:
- If you want to add connectors (or other initialization code), override OnCreate() and add connectors via In("name") or Out("name"). Currently all math nodes use double as type, so you best stick to that. Other useful types are bool, vector3 and quaternion. More may be added later.
- To get input data, use In("name").AsSomeType(). No need to check for null here, a default value will always be provided.
- Execute any active code in (if your node inherits from RootNode or ExecutableNode) OnExecute(). Update output node data in OnUpdateOutputData()
- To output data use Out("ConnectorName", value)
- To access game data, use "Program." (for example Program.Vessel, Program.VesselInfo...)
