Utilizing the namespace importation method correctly

Question

Utilizing the namespace importation method correctly

How can I efficiently utilize classes from a namespace that may be the same or different from the current file's namespace?

I currently have the following two files.

TypeA.ts:

export namespace Game {
@ccclass
export class TypeA extends cc.Component {

    protected onLoad(): void {
        // do something
    }
}}

TypeB.ts:

import * s from "some url";

export namespace Game {
@ccclass
export class TypeB extends s.Game.TypeA {

    protected onLoad(): void {
        // do something
    }
}}

In the import section, Visual Studio Code is expecting 'as' but I am able to enter any string and it still works. Additionally, the extension of TypeB looks messy and lengthy due to the nested namespaces.

Is there a way to simplify the syntax to just have TypeB extend TypeA since both are within the same namespace? I have many other classes/components planned to be placed under the same namespace - should I proceed with this approach or remove the export namespace part for easier accessibility?

Similar to any other form of declaration, two namespaces with matching names are only considered "the same namespace" if they are declared within the same scope: whether it be global or under the same parent namespace or external module. In this scenario, there are two distinct namespaces named Game, each residing in a different module. If you desire to extend the same namespace from both modules, you could employ the following approach in TypeA.ts:

declare global {
    namespace Game {
        class TypeA extends cc.Component {
            onLoad(): void;
        }
    }
}
Game.TypeA = <any>function(this: Game.TypeA) {
    // constructor
};
Game.TypeA.prototype.onLoad = function() {
    // perform an action
};

A similar procedure would be followed in TypeB.ts. However, this method becomes quite convoluted since the declare global statement can solely accommodate declarations and the actual implementation has to be separately appended. It may be wiser to heed Cerberus's advice and opt for either namespaces or external modules exclusively.
