DELEGATES IN UNITY:

A delegate is a reference pointer to a method. When it is called, it gives notification to all methods that reference the delegate. It allows us to treat a method as a variable and pass method as a variable for a callback. The basic idea of a delegate is exactly the same as a subscription magazine. Anyone can subscribe to the services and they will receive the update at the right time automatically.

TYPES of Delegate:

1.Single Delegate:- It can reference to only single method at a time.

2.Multicast Delegate:- It can store the reference of multiple methods at a time.

SYNTAX :

//Defining Delegates

public delegate void OnMouseClickDelegte();

public static OnMouseClickDelegte mouseClickDelegate;

//Subscribing to a delegate

// eg. of singlecast delegate

mouseClickDelegate = myExampleMethod;

//eg. of multicast delegate

mouseClickDelegate += myExampleMethod;

mouseClickDelegate +=myAnotherExampleMethod;

//Calling delegates

mouseClickDelegate();

//UnSubscribing to delegates

mouseClickDelegate -= myExampleMethod;

mouseClickDelegate -=myAnotherExampleMethod;
