Warning

Project is currently in a weird transition state. Removing the force direction and focusing on just making it a clean simple node editor. The information below is out of date.

A scriptable object framework and node graph UI that lets you easily create complex branching trees of data.

Force Directed

Nodes are positioned automically using a force-direction algorithm.

Nodes can be pinned freezing them in place.

Scriptable Objects

A Graph object can contain Node and Connection objects that connect with each other to create a tree.

Inside the Graph object you define what sort of nodes and connection the class supports, and any connection rules between the two you require.

using Less3.ForceGraph;
public class GenerationGraph : ForceGraph
{
    public override List<(string, Type)> GraphNodeTypes()
    {
        return new List<(string, Type)>
        {
            ("GenNode" , typeof(GenerationNode))
        };
    }
    public override Dictionary<Type, List<(string, Type)>> GraphConnectionTypes()
    {
        return new Dictionary<Type, List<(string, Type)>>
        {
            {typeof(GenerationNode), new List<(string,Type)>() {
                ("Gen Connection", typeof(GenerationConnection))
            }}
        };
    }

    public override bool ValidateConnectionRequest(ForceNode from, ForceNode to, Type connectionType)
    {
        return true;// assume all connections are valid
    }
}

Connections and Nodes behave as simple scriptable objects you can fill with whatever data you need.

public class GenerationNode : ForceNode
{
    public float exampleData;
}

public class GenerationConnection : ForceConnection
{
    public float helloThere;
}
