API Reference

Sending a message in the chat

sendChatMessage(message: string, author: string): void

Sends a message in the chat. The message is only visible in the browser of the current user.

• message: the message to be displayed in the chat
• author: the name displayed for the author of the message. It does not have to be a real user.

Example:

WA.sendChatMessage('Hello world', 'Mr Robot');

Listening to messages from the chat

onChatMessage(callback: (message: string) => void): void

Listens to messages typed by the current user and calls the callback. Messages from other users in the chat cannot be listened to.

• callback: the function that will be called when a message is received. It contains the message typed by the user.

Example:

WA.onChatMessage((message => {
    console.log('The user typed a message', message);
}));

Detecting when the user enters/leaves a zone

onEnterZone(name: string, callback: () => void): void
onLeaveZone(name: string, callback: () => void): void

Listens to the position of the current user. The event is triggered when the user enters or leaves a given zone. The name of the zone is stored in the map, on a dedicated layer with the zone property.

The `zone` property, applied on a layer

• name: the name of the zone, as defined in the zone property.
• callback: the function that will be called when a user enters or leaves the zone.

Example:

WA.onEnterZone('myZone', () => {
    WA.sendChatMessage("Hello!", 'Mr Robot');
})

WA.onLeaveZone('myZone', () => {
    WA.sendChatMessage("Goodbye!", 'Mr Robot');
})

Opening a popup

In order to open a popup window, you must first define the position of the popup on your map.

You can position this popup by using a "rectangle" object in Tiled that you will place on an "object" layer.

openPopup(targetObject: string, message: string, buttons: ButtonDescriptor[]): Popup

• targetObject: the name of the rectangle object defined in Tiled.
• message: the message to display in the popup.
• buttons: an array of action buttons defined underneath the popup.

Action buttons are ButtonDescriptor objects containing these properties.

• label (string): The label of the button.
• className (string): The visual type of the button. Can be one of "normal", "primary", "success", "warning", "error", "disabled".
• callback ((popup: Popup)=>void): Callback called when the button is pressed.

Please note that openPopup returns an object of the Popup class. Also, the callback called when a button is clicked is passed a Popup object.

The Popup class that represents an open popup contains a single method: close(). This will obviously close the popup when called.

class Popup {
    /**
     * Closes the popup
     */
    close() {};
}

Example:

let helloWorldPopup;

// Open the popup when we enter a given zone
helloWorldPopup = WA.onEnterZone('myZone', () => {
    WA.openPopup("popupRectangle", 'Hello world!', [{
        label: "Close",
        className: "primary",
        callback: (popup) => {
            // Close the popup when the "Close" button is pressed.
            popup.close();
        }
    });
}]);

// Close the popup when we leave the zone.
WA.onLeaveZone('myZone', () => {
    helloWorldPopup.close();
});

Disabling / restoring controls

disablePlayerControls(): void
restorePlayerControls(): void

These 2 methods can be used to completely disable player controls and to enable them again.

When controls are disabled, the user cannot move anymore using keyboard input. This can be useful in a "First Time User Experience" part, to display an important message to a user before letting him/her move again.

Example:

WA.onEnterZone('myZone', () => {
    WA.disablePlayerControls();
    WA.openPopup("popupRectangle", 'This is an imporant message!', [{
        label: "Got it!",
        className: "primary",
        callback: (popup) => {
            WA.restorePlayerControls();
            popup.close();
        }
    }]);
});

Opening a web page in a new tab

openTab(url: string): void

Opens the webpage at "url" in your browser, in a new tab.

Example:

WA.openTab('https://www.wikipedia.org/');

Opening a web page in the current tab

goToPage(url: string): void

Opens the webpage at "url" in your browser in place of WorkAdventure. WorkAdventure will be completely unloaded.

Example:

WA.goToPage('https://www.wikipedia.org/');

Opening/closing a web page in an iFrame

openCoWebSite(url: string): void
closeCoWebSite(): void

Opens the webpage at "url" in an iFrame (on the right side of the screen) or close that iFrame.

Example:

WA.openCoWebSite('https://www.wikipedia.org/');
// ...
WA.closeCoWebSite();

Load a sound from an url

loadSound(url: string): Sound

Load a sound from an url

Please note that loadSound returns an object of the Sound class

The Sound class that represents a loaded sound contains two methods: play(soundConfig : SoundConfig|undefined) and stop()

The parameter soundConfig is optional, if you call play without a Sound config the sound will be played with the basic configuration.

Example:

var mySound = WA.loadSound("Sound.ogg");
var config = {
    volume : 0.5,
    loop : false,
    rate : 1,
    detune : 1,
    delay : 0,
    seek : 0,
    mute : false
}
mySound.play(config);
// ...
mySound.stop();

Show / Hide a layer

WA.showLayer(layerName : string): void
WA.hideLayer(layerName : string) : void

These 2 methods can be used to show and hide a layer.

Example :

WA.showLayer('bottom');
//...
WA.hideLayer('bottom');

Set/Create properties in a layer

WA.setProperty(layerName : string, propertyName : string, propertyValue : string | number | boolean | undefined) : void;

Set the value of the propertyName property of the layer layerName at propertyValue. If the property doesn't exist, create the property propertyName and set the value of the property at propertyValue.

Example :

WA.setProperty('wikiLayer', 'openWebsite', 'https://www.wikipedia.org/');

Listen to player movement

onPlayerMove(callback: HasPlayerMovedEventCallback): void;

Listens to the movement of the current user and calls the callback. Sends an event when the user stops moving, changes direction and every 200ms when moving in the same direction.

The event has the following attributes :

• moving (boolean): true when the current player is moving, false otherwise.
• direction (string): "right" | "left" | "down" | "top" the direction where the current player is moving.
• x (number): coordinate X of the current player.
• y (number): coordinate Y of the current player.

callback: the function that will be called when the current player is moving. It contains the event.

Example :

WA.onPlayerMove(console.log);

Getting informations on the current user

getCurrentUser(): Promise<User>

Return a promise that resolves to a User object with the following attributes :

• id (string) : ID of the current user
• nickName (string) : name displayed above the current user
• tags (string[]) : list of all the tags of the current user

Example :

WA.getCurrentUser().then((user) => {
    if (user.nickName === 'ABC') {
        console.log(user.tags);
    }
})

Getting informations on the current room

getCurrentRoom(): Promise<Room>

Return a promise that resolves to a Room object with the following attributes :

• id (string) : ID of the current room
• map (ITiledMap) : contains the JSON map file with the properties that were setted by the script if setProperty was called.
• mapUrl (string) : Url of the JSON map file
• startLayer (string | null) : Name of the layer where the current user started, only if different from start layer

Example :

WA.getCurrentRoom((room) => {
    if (room.id === '42') {
        console.log(room.map);
        window.open(room.mapUrl, '_blank');
    }
})

Add a custom menu

registerMenuCommand(commandDescriptor: string, callback: (commandDescriptor: string) => void): void

Add a custom menu item containing the text commandDescriptor. A click on the menu will trigger the callback.

Example :

WA.registerMenuCommand('About', () => {
    console.log("The About menu was clicked");
});

Working with group layers

If you use group layers in your map, to reference a layer in a group you will need to use a / to join layer names together.

Example :

The name of the layers of this map are :

• entries/start
• bottom/ground/under
• bottom/build/carpet
• wall
