Wonderland Engine API

The bindings between Wonderland Engine's WebAssembly runtime and custom JavaScript or TypeScript components.

Learn more about Wonderland Engine at https://wonderlandengine.com.

💡 The Wonderland Engine Runtime is compatible on all patch versions of the API, but the major and minor versions are required to match.

Example: You will be able to use Wonderland Editor 1.0.4 with API version 1.0.0 or 1.0.9 for example, but not with API 1.1.0. 💡

Usage

Wonderland Engine projects usually come with this package pre-installed. Install via npm or yarn:

npm i --save @wonderlandengine/api
# or:
yarn add @wonderlandengine/api

To update the API to the latest version use

npm i --save @wonderlandengine/api@latest

Writing a Custom Component

JavaScript

import {Component, Property} from '@wonderlandengine/api';

class Forward extends Component {
    static TypeName = 'forward';
    static Properties = {
        speed: Property.float(1.5)
    };

    _forward = new Float32Array(3);

    update(dt) {
        this.object.getForward(this._forward);
        this._forward[0] *= this.speed*dt;
        this._forward[1] *= this.speed*dt;
        this._forward[2] *= this.speed*dt;
        this.object.translateLocal(this._forward);
    }
}

TypeScript

import {Component} from '@wonderlandengine/api';
import {Component} from '@wonderlandengine/api/decorators.js';

class Forward extends Component {
    static TypeName = 'forward';

    @property.float(1.5)
    speed!: number;

    private _forward = new Float32Array(3);

    update(dt) {
        this.object.getForward(this._forward);
        this._forward[0] *= this.speed*dt;
        this._forward[1] *= this.speed*dt;
        this._forward[2] *= this.speed*dt;
        this.object.translateLocal(this._forward);
    }
}

For Library Maintainers

To ensure the user of your library can use a range of API versions with your library, use "peerDependencies" in your package.json:

"peerDependencies": {
    "@wonderlandengine/api": ">= 1.0.0 < 2"
},

Which signals that your package works with any API version >= 1.0.0 (choose the lowest version that provides all features you need) until 2.0.0.

Installation

Make sure to install dependencies first:

npm i

Build

To build the TypeScript code, use one of:

npm run build
npm run build:watch

Test

To run all the tests, use:

npm run test -- --deploy path/to/wonderland/deploy

It's required to pass the Wonderland Editor deploy folder as a CLI argument using the --deploy argument.

If no such flag is passed, the test framework will assume that the deploy folder is located in ../../deploy.

Test Projects

Some tests use projects as inputs, e.g.,

  • animation.tests.ts
  • component.tests.ts
  • mesh.tests.ts
  • scene.test.ts
  • scene-gltf.test.ts

Those projects are required to be built before the tests can run. You can build all projects using:

npm run test:build -- path/to/wonderlandengine

Each projects deploy/ will be copied into test/resources/projects.

Test File

To run the tests in a file, use:

 npm run test -- [PATH] --deploy path/to/wonderland/deploy

Example with the component file:

npm run test -- ./test/component.test.ts --deploy path/to/wonderland/deploy

Watch

It's possible to watch one/multiple test(s) using --watch:

npm run test -- --deploy path/to/wonderland/deploy --watch

Grep

The runner uses Mocha, which supports filtering tests using regexp.

You can provide a regexp using --grep or -g:

npm run test -- -g 'MeshComponent'

The grep flag can be mixed with the positional file argument:

npm run test -- ./test/component.test.ts -g 'MeshComponent'

This command will only run the tests matching the "MeshComponent" string in the test/component.test.ts file.
