How do you use the Unity commission?

In Unity, delegates are a type used for callback functions. They allow you to pass a function as a parameter to another function and call these functions when needed.

Here are common methods for using delegation:

1. Declare a delegate type: Declare a delegate type in the code, specifying the signature of the methods that the delegate can reference.

public delegate void MyDelegate(int parameter);

2. Create a delegate instance: Use a delegate type to create a delegate instance and specify the method to be invoked.

MyDelegate myDelegate = new MyDelegate(MyMethod);

3. Define a callback function: Create a method in the code that matches the signature of the delegate.

void MyMethod(int parameter)
{
    // 做一些操作
}

4. Invoking a delegate: Using a delegate instance to call the method referenced by the delegate.

myDelegate(10);

The above is the basic method of using delegates in Unity. Delegates can be used for event handling, multicast delegates, and other scenarios that require callback functions.
