Web, Mobile, and API development is a crazy maze of technological choices. While discussing technologies and various options, Non-Technical people struggle to make any sense out of these terms because these are mere words for them.

Dynamic  Components in Angular | Tudip

What are the Dynamic Components:

Dynamic components are instantiated and used in an application at runtime. They are reusable and used in any framework/library making building large-scale apps way easier.

How to use Dynamic Components in Angular Project:

Firstly, Generate a new Angular project, and make sure that you have the angular CLI installed and setup accordingly.

Examples:

ng-template :

It allows declaring a part of the HTML in the Angular Template. So, it is a better way to give a chance to use dynamism in our component which will be used in other components.

In your app.component.html file, Add ng-template in your HTML file.

<ng-template #test></ng-template>

If you run your application, you will not see text rendering on your component. This is because the text is not loaded yet in your DOM. Currently, ng-template grabbed it and used it in other components where it was needed.

How to grab the HTML template in your component:

Steps:

1. Viewchild:

This is an Angular Decorator that will configure the view query. It matches the selector that view in the DOM. It also takes the local variables as a parameter.

Import ViewChild from ‘angular/core’;

export class AppComponent implements OnInit, AfterViewInit{ @ViewChild(‘test’, { read: ViewContainerRef }) container;}

2. ViewContainerRef:

ViewContainerRef is a reference for a container. It stores a reference to the template element.

<ng-template #test></ng-template> <button (click)="addComponent('success')">Create success alert</button> <button (click)="addComponent('danger')">Create danger alert</button>

Before we go to the click method , we need to add a new service The ComponentFactoryResolver service exposes one primary method, resolveComponentFactory.

3. ComponentFactoryResolver:

Generally, the Angular compiler generates a ComponentFactory for any component referenced in a template. They load at runtime because there are no selector references in the templates for dynamically loaded components.

constructor(private resolver: ComponentFactoryResolver) {}

addComponent (type) { this . container . clear (); const factory : ComponentFactory = this .resolver. resolveComponentFactory (TestComponent); this . componentRef = this . container . createComponent ( factory ); this . componentRef . instance . type = type; // this.componentRef.instance.output.subscribe(event => console.log(event)); } 

The resolveComponentFactory() method takes a component and returns a ComponentFactory.

Details:

1. this. container. clear ();

While loading another view, we have to remove the previous view, otherwise, it will append more components to the container.

2. const factory : ComponentFactory = this .resolver. resolveComponentFactory (TestComponent);

The resolveComponentFactory() method takes a component and returns the recipe for how to create a component.

3. We are calling the addComponent() method with the recipe. Internally this method will call the create() method from the factory and will append the component as a sibling to our container.

this. componentRef = this . container. createComponent ( factory );

Now we have got a reference to other components, and we can set the type Input as:

this. componentRef . instance. type = type;

4. You can also subscribe to a component Output like this:

this.componentRef.instance.output.subscribe(event => console.log(event));

5. And don’t forget to destroy the component:

ngOnDestroy() { this.componentRef.destroy(); } 

6. Add your dynamic components to the entry components section:

@NgModule({ entryComponents: [ TestComponent ], }) export class AppModule {}

Challenge

The main challenge in Bubble Trouble Roku was to shoot the bubble then bubble splits into smaller bubbles, and each bubble should be destroyed to complete the level. To design the game board which would consist of the shooter, timing bar and bubbles. Also handle the left, right and OK click controls. To implement the multiple bubble poster nodes during the game play and set the circular moving animation to it. The score to be calculated based on two different conditions, i.e. the number of balls destroyed and saved time in the total allocated time.

Progress:

Initially we designed the game board having shooter, timing bar and ball using the scene graph’s different renderable nodes. We used different scene graph roSG Node to create the multiple poster and animation nodes during the game play and set the circular moving animation of bubbles. Implemented logic in brightscript to calculate a position to move the bubble poster nodes in a circular pattern. Implemented logic in BrightScript for calculating the number of balls destroyed and remaining time of the total allocated time.

Result:

Successfully designed the game board and handle the left, right, and ok click control to move the shooter and shoot to bubble. Completed the smooth animation for moving the bubble in a circular pattern using multiple poster and animation nodes created during the game play. Bubble Trouble lovers finally found their favorite game at the Roku Channel Store.
