Multicast delegate API

Effect

The calling end takes effect

Example usage: Create a script called "MultidelExample", open the script, enter the following code to save, run the game, and print out a+b:5.

ts
@Component
 export default class MultidelExample extends Script {

     // Example function that satisfies the DelegateFuncType constraint
     public addNumbers(a: number, b: number): number {
         let c = a + b;
         console.log("a+b:"+ c);
         return c;
     }
     protected onStart(): void {

         // Instantiate MulticastDelegate class
         const delegateInstance = new MulticastDelegate<typeof this.addNumbers>();
         // Method for adding MulticastDelegate instance
         delegateInstance.add(this.addNumbers);
         // Method for broadcasting MulticastDelegate instances
         delegateInstance.broadcast(2,3);
     }
 }
@Component
 export default class MultidelExample extends Script {

     // Example function that satisfies the DelegateFuncType constraint
     public addNumbers(a: number, b: number): number {
         let c = a + b;
         console.log("a+b:"+ c);
         return c;
     }
     protected onStart(): void {

         // Instantiate MulticastDelegate class
         const delegateInstance = new MulticastDelegate<typeof this.addNumbers>();
         // Method for adding MulticastDelegate instance
         delegateInstance.add(this.addNumbers);
         // Method for broadcasting MulticastDelegate instances
         delegateInstance.broadcast(2,3);
     }
 }
