UnityEventAddListener

UnityEventAddListener is a method used in the Unity game engine to add a listener to a UnityEvent. UnityEvent is a class that allows for the creation of custom events in Unity, which can be used to trigger functions or methods when certain conditions are met. The AddListener method is used to subscribe a method to the event, so that when the event is invoked, the subscribed method is called.

The AddListener method takes a single parameter, which is a delegate representing the method to be called when the event is invoked. The delegate must have the same signature as the event, meaning it must have the same return type and parameters. The method to be called can be an instance method, a static method, or an anonymous method.

When the event is invoked using the Invoke method, all of the subscribed methods are called in the order they were added. If a method is added multiple times, it will be called multiple times as well. The RemoveListener method can be used to unsubscribe a method from the event, so that it is no longer called when the event is invoked.

UnityEventAddListener is a powerful tool for creating custom events and managing the flow of data and control in a Unity project. By using events and listeners, developers can create more modular and reusable code, and make it easier to manage complex interactions between different parts of a game or application.
