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;
        this._forward[1] *= this.speed;
        this._forward[2] *= this.speed;
        this.object.translate(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;

    _forward = new Float32Array(3);

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

For Library Maintainers

To ensure the user of your library can use a range of API versions with your library, use "peerDepenedencies" 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 whichever version has all the features you need) until 2.0.0.

Also see the Writing JavaScript Libraries Tutorial.

API <> Runtime Versioning

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 probably not with API 1.1.0.
