Event Nodes (Manually)

This guide will walk you through creating event nodes in Jungle manually. Let's get started!

Step 1: Create a New C# Script​

First, create a new C# script in your Unity project.

Step 2: Inherit from EventNode​

Next, make your new class inherit from the EventNode class. This will form the foundation of your event node.

using Jungle;

//                         ↓↓↓↓↓↓↓↓↓
public class MyEventNode : EventNode
{

}

Step 3: Implement OnStart and OnUpdate​

Now, you need to implement the OnStart and OnUpdate methods.

using Jungle;

public class MyEventNode : EventNode
{
    //                      ↓↓↓↓↓↓↓
    protected override void OnStart()
    {

    }

    //                      ↓↓↓↓↓↓↓↓
    protected override void OnUpdate()
    {

    }
}

Step 4: Add the EventNode Attribute​

Add the EventNode attribute to your class. This defines the output ports.

using Jungle;

// ↓↓↓↓↓↓↓
[EventNode(
    OutputPortNames = new []
    {
        "My Output 1",
        "My Output 2"
    },
    OutputPortTypes = new []
    {
        typeof(OUTPUT_TYPE),
        typeof(OUTPUT_TYPE)
    }
)]
public class MyEventNode : EventNode
{
    protected override void OnStart()
    {

    }

    protected override void OnUpdate()
    {

    }
}

Step 5: Add the NodeProperties Attribute​

Finally, add the NodeProperties attribute to your class. This defines additional properties such as the title, description, and category of your node.

using Jungle;

// ↓↓↓↓↓↓↓↓↓↓↓↓
[NodeProperties(
    Title = "My Event Node",
    Description = "This is an Event node.",
    Category = "My Nodes/Event",
    Color = Green
)]
[EventNode(
    OutputPortNames = new []
    {
        "My Output 1",
        "My Output 2"
    },
    OutputPortTypes = new []
    {
        typeof(OUTPUT_TYPE),
        typeof(OUTPUT_TYPE)
    }
)]
public class MyEventNode : EventNode
{
    protected override void OnStart()
    {

    }

    protected override void OnUpdate()
    {

    }
}

With these steps, you've created a basic event node in Jungle. Feel free to customize the output properties to suit your needs!
