UnityEvents for UdonSharp

⚠️ VUdon Events is heavily experimental and may break without a notice! Use at your own risk.

VUdon - Events

VUdon Events ("UdonEvents") allows you to nearly natively implement UnityEvents into UdonSharp.

How to use VUdon Events

using UdonSharp;
using UnityEngine;
using VRC.SDK3.Data;
using VRC.SDKBase;

namespace Varneon.VUdon.UdonEvents
{
    public class UdonEventTest : UdonSharpBehaviour
    {
        // Declare a serialized hidden field for the event handler singleton
        [SerializeField, HideInInspector]
        private UdonEventHandler udonEventHandler;

        // Declare a serialized DataList field for each UdonEvent
        [SerializeField, UdonEvent]
        private DataList onPlayerTriggerEntered;

        // Add UdonEventAttribute to the DataList fields for overriding
        // the property drawer with the UdonEvent drawer
        [SerializeField, UdonEvent]
        private DataList onPlayerTriggerExited;

        public override void OnPlayerTriggerEnter(VRCPlayerApi player)
        {
            // Invoke the UdonEvent's persistent calls stored in the DataList field
            udonEventHandler.Invoke(onPlayerTriggerEntered);
        }

        public override void OnPlayerTriggerExit(VRCPlayerApi player)
        {
            // UdonEventHandler can invoke a list of calls by providing it the DataList
            udonEventHandler.Invoke(onPlayerTriggerExited);
        }
    }
}

📦 UdonSharp scripts in a UPM package will need an assembly definition reference to Varneon.VUdon.Events.Runtime
