CE GraphBridge

CE.GraphBridge exposes C# methods and properties to graph tooling via attributes and editor generators.

Quick Start

using UdonSharp.CE.GraphBridge;
using UnityEngine;

public static class MathNodes
{
    [GraphNode("Math/Lerp Vector3")]
    public static Vector3 LerpVector3(
        [GraphInput("Start")] Vector3 a,
        [GraphInput("End")] Vector3 b,
        [GraphInput("T")] float t)
    {
        return Vector3.Lerp(a, b, t);
    }
}

Run the generator from the Unity menu: Udon CE/Graph Bridge/Generate Nodes.

API Reference

Node Attributes

Attribute	Description
GraphNode	Expose a method as a node.
GraphInput	Customize input ports and defaults.
GraphOutput	Customize output ports for out parameters.
GraphFlowOutput	Define flow outputs for branching nodes.
GraphProperty	Expose properties as Get/Set nodes.
GraphEvent	Expose methods as graph events.
GraphCategory	Group node classes under a menu category.
GraphTypeConstraint	Restrict generic parameter types.

Editor Tools

Menu Path	Purpose
Udon CE/Graph Bridge/Node Browser	Explore generated nodes.
Udon CE/Graph Bridge/Validate Nodes	Validate node definitions.
Udon CE/Graph Bridge/Generate Nodes	Generate node assets.
Udon CE/Graph Bridge/Generate Wrappers	Generate wrappers for graph access.
Udon CE/Graph Bridge/Generate Documentation	Generate graph node docs.

Common Pitfalls

Bad

[GraphNode("Math/Hidden")]
private static float Hidden(float v) { return v; } // Private methods are not exported

Good

[GraphNode("Math/Visible")]
public static float Visible(float v) { return v; }
