Extended Events is an event system that allows you to serialize almost any method and data type. It allows creating multiple callback types in a single event object and invoking events with a delay.
Render pipeline compatibility
The Built-in Render Pipeline is Unity’s default render pipeline. It is a general-purpose render pipeline that has limited options for customization. The Universal Render Pipeline (URP) is a Scriptable Render Pipeline that is quick and easy to customize, and lets you create optimized graphics across a wide range of platforms. The High Definition Render Pipeline (HDRP) is a Scriptable Render Pipeline that lets you create cutting-edge, high-fidelity graphics on high-end platforms.

Description

[Documentation] [Forum] [Demo]


Extended Events is an event system that allows you to setup and configure persistent event callbacks via the Inspector.

Based on UnityEvents it has fewer restrictions and allows you to serialize almost any method or data type.


1. Methods

Extended Events supports any method or operator with up to 8 parameters (up to 7 for instance methods). Also supports instance methods defined on structs.

Extended Events allows methods with any return type and allows the returned value to be used as a parameter in other methods.


2. Parameter Types and serialization

Extended Events support methods that take any type as the parameters. It also allow to natively serialize following parameters:

bool, int, float, string, types derived UnityEngine.Object and interfaces defined on those types, enums, uint, LayerMask, Vector2, Vector3, Vector4, Color, Quaternion, character, Type, Rect, AnimationCurve, Gradient.

Extended Events also allows users to create their own serializers and PropertyDrawers to serialize any type (such as custom structs or classes).


3. Multiple callback types

Extended Events allows to create multiple callback types in a single event object. (for example if you want to have both “OnTriggerEnter” and “OnTriggerExit” callbacks on the same event object).


4. Invoking with a Custom argument

Extended Events allows methods to be invoked with a custom parameter (such as Collision for OnCollisionEnter/Exit or Collider for OnTriggerEnter/Exit messages).


5. Timeline, coroutines and iteration

Extended Events allows methods to be invoked with a delay and it also can start/stop a coroutine without using a separate method

Extended Events also allows user to invoke an event on an enumerator (including lists and arrays).


6. Custom ParameterDrawers

Extended Events allows user to define custom parameter drawers for any parameter on any method. PropertyDrawers can also be used for method parameters.
