API UI functions Reference

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.

WA.ui.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.room.onEnterZone('myZone', () => {
    WA.ui.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.room.onLeaveZone('myZone', () => {
    helloWorldPopup.close();
});

Add custom menu

WA.ui.registerMenuCommand(menuCommand: string, callback: (menuCommand: string) => void): void

Add a custom menu item containing the text commandDescriptor in the main menu. A click on the menu will trigger the callback. Custom menu exist only until the map is unloaded, or you leave the iframe zone of the script.

Example:

WA.ui.registerMenuCommand("test", () => {
    WA.chat.sendChatMessage("test clicked", "menu cmd")
})

Awaiting User Confirmation (with space bar)

WA.ui.displayActionMessage(message: string, callback: () => void): ActionMessage

Displays a message at the bottom of the screen (that will disappear when space bar is pressed).

Example:

const triggerMessage = WA.ui.displayActionMessage("press 'space' to confirm", () => {
    WA.chat.sendChatMessage("confirmed", "trigger message logic")
});

setTimeout(() => {
    // later
    triggerMessage.remove();
}, 1000)

Please note that displayActionMessage returns an object of the ActionMessage class.

The ActionMessage class contains a single method: remove(): Promise<void>. This will obviously remove the message when called.

class ActionMessage {
    /**
     * Hides the message
     */
    remove() {};
}
