uNode is a powerful visual scripting solution for Unity. It allows you to create complex game logic, AI behaviors, and interactions without writing a single line of code. Whether you're a beginner or an experienced developer, uNode empowers you to build interactive systems using a visual interface.
Download: latest | pro version
- No Coding Required : With uNode, you can express your ideas visually using nodes and connections. Say goodbye to syntax errors and debugging headaches!
- Flexibility : uNode seamlessly integrates with Unity existing components. You can create custom nodes, extend functionality, and even integrate C# scripts when needed.
- Performance : uNode generates optimized C# code behind the scenes, ensuring that your visual graphs run efficiently in your game.
| Feature | Description |
|---|---|
| Flow Graphs | Powerful flow graphs for low-level logic and complex tasks. |
| State Graphs | Powerful state graphs which combine Flow, State Machine, and Behavior Tree into one graphs. |
| Macros | Create a graph once and reuse them in entire graphs with different parameters |
| Runtime Graphs | Graph that can be run with Reflection or Native C#. It provide quick prototyping, live editing and fast compiling. This has many graph types for different scenario, see more at: here |
| C# Graphs | Graph that intended only for produce c# script for more advanced task. |
| ECS Graph | (Experimental) DOTS support for uNode. You need to install it before it can be used. |
More graph info can be found on: https://docs.maxygames.com/unode3/manual/basic-concepts/graphs.html
| Feature | Description | Availability |
|---|---|---|
| C# Script Generation | Graphs will be automatically converted to C# scripts in order to maximize runtime performance. | ✅ |
| Fast Enter Play Mode | Support fast enter play mode, By fast enter/exit play mode you can quickly test and prototype ideas. | ✅ |
| Dynamic Nodes | Use automatically generated nodes for all and any Unity functionality, your code and 3rd party APIs. Including Methods, Properties, Fields, Unity Events, C# Events, Generic Methods, Constructors and Operators. |
✅ |
| Built-in Documentation | Get instant access to Unity and custom documentation directly from the Editor. | ✅ |
| Live Editing | Modify any part of your graphs while in playmode to quickly prototype and test ideas | ✅ |
| Instant Node Search | Get instant node searching without the need to rebuild node library. The node library is instantly refreshed based on using namespaces in each graph or can be customized in preference. |
✅ |
| Graph Organizing | Use namespace, variable & function grouping, region / node group, comment, and notes to fully organize your graphs. | ✅ |
| Graph Inheritance | Enables you to create new graph that reuse, extend, and modify the behavior defined in other graph | ✅ |
| Graph Debugging | Insert breakpoints, watch connection, and watch variable changed in a graphs. It can also debug connection and log to console with specific message when it reach the connection ( Pro Only ) |
✅ |
| C# Parser | Quickly convert c# script into uNode graphs file, with support most of c# syntax. You can find c# script in the internet or use ChatGPT to generate c# script and then use C# Parser to convert it to uNode graph. |
Pro Only |
| Realtime C# Preview | Preview generated c# script in realtime with syntax highlighting. It will also highlight parts of the C# code that correspond to the selected graph elements in your graph. There's c# preview for free version but the feature are limited. |
Pro Only |
| Find References | Quickly find all references/usages for variable, property, function, graph and nodes in project | Pro Only |
| Graph Hierarchy | Easily navigate through your graph, find functions, macros, and see which nodes are currently active. | Pro Only |
| Graph Search | Search all graph members ( graph, variable, property, etc ) in project easily. | Pro Only |
| Graph Trimming | Minimize build size by trimming graph at build time useful for targeting WebGL and mobile builds. | Pro Only |
Supported Type: All Type are supported ( Classes, Structs, Enums, Collections, Interfaces, etc ).
uNode has 2 options to run the graphs:
- Native C# (Auto in Build). The performance is same or near to handwritten c# script and it's by far the most faster visual scripting for Unity.
- Optimized Reflection Slow compared to native c# but its live editable.
- Development Platforms: Support all platforms that Unity support.
- Works on Unity Pro and Free
- uNode 3 uses of Odin Serializer, therefore API compatibility level .NET 4.x is required.
- uNode 3 is not compatible with uNode 2.
- Unity 2022.3 or later
- Open Package Manager from Window > Package Manager.
- Click the "+" button > Add package from git URL.
- Enter the following URL:
https://github.com/wahidrachmawan/uNode.git?path=Assets/uNode3
Alternatively, open Packages/manifest.json and add the following to the dependencies block:
{
"dependencies": {
"com.maxygames.unode": "https://github.com/wahidrachmawan/uNode.git?path=Assets/uNode3"
}
