The radial-menu is part of the Gameface custom Components suite.


npm i coherent-gameface-radial-menu

Usage with UMD:

<script src="./node_modules/coherent-gameface-radial-menu/dist/radial-menu.production.min.js"></script>
  • add the radial-menu Component to your html:

This is all! Load the file in Gameface to see the radial-menu.

Usage with JavaScript:

If you wish to import the RadialMenu using JavaScript you can remove the script tag and import it like this:

import { RadialMenu } from 'coherent-gameface-radial-menu';

or simply

import 'coherent-gameface-radial-menu';

Note that this approach requires a module bundler like Webpack or Rollup to resolve the modules from the node_modules folder.

Features and Configuration

The radial menu has a few data-* attributes by which it is configured.

Here is an example with all available attributes:

	data-name="Radial Menu"

The id attribute is added so the radial menu instance can be accessed later for providing the items to it. It is not required.


Set the name by providing data-name="Example Name". This will be visualized at the center of the menu.

Assign Open Key

Set a key for opening the menu by directly providing a keyCode value to the data-open-key-code attribute or use some of the defined names in the components.KEYCODES object e.g. HOME, CTRL, SPACE.

Populate Items

Create segments in the menu by providing an exposed array of items to the instance of the targeted radial menu on the items property like so:

const radialMenuOne = document.getElementById('radial-menu-one');
// Provide the items.
radialMenuOne.items = itemsModel.items;


The radial-menu-center slot specifies the element in the middle of the menu. By default there is a circle background - bullseye and a text. You can customize them. Currently the slot in the template contains:

<component-slot class="guic-radial-menu-center" data-name="radial-menu-center">
    <div class="guic-radial-menu-center-bullseye"></div>
    <div class="guic-radial-menu-center-text">Radial Menu</div>

You can add an element with a background image for example:

<gameface-radial-menu id="radial-menu-one">
    <div slot="radial-menu-center" class="radial-menu-center">
        <div class="radial-menu-center-bullseye"></div>
        <div class="radial-menu-center-image"></div>

The the styles for radial-menu-center-bullseye, radial-menu-center-image and radial-menu-center are:

.radial-menu-center-bullseye {
    position: absolute;
    width: 80%;
    height: 80%;
    background-color: #4a9cc5;
    border-radius: 50%;

.radial-menu-center-image {
    position: absolute;
    width: 80%;
    height: 80%;
    background-image: url('./images/GameMessage_AchievmentIcon.png');
    background-size: cover;
    background-repeat: no-repeat;

.radial-menu-center {
    position: absolute;
    width: 23.7vh;
    height: 23.7vh;
    display: flex;
    justify-content: center;
    align-items: center;

Note: Any additional elements in the slot should have a position property in order to be visible in this case i.e. to be higher in the stacking (context) order.


  • Provide the name of the event that will be emitted by the component (instance) when another item is highlighted to the data-change-event-name attribute.

  • Provide the name of the event that will be emitted by the component (instance) when an item is selected to the data-select-event-name attribute.

A basic approach which allows executing code through the event and the code or the attached functions are decoupled from the component itself.

Listener for Opening

If case there is a need to disable the radial menu from opening, just get the component Element object and call removeOpenKeyEvent().


const radialMenuOne = document.getElementById('radial-menu-one');

Then re-add the listener with radialMenuOne.addOpenKeyEvent() when needed.

In case the key with which the radial menu should be opened needs to change, before adding the event, change the keyCode with radialMenuOne.openKeyCode = <number>;

Specifications Overview

  • Event listeners for mousemove, click, resize and keyup are added on opening the menu and removed when it is closed.

  • The topmost item's segment id is 0 and the first item from the provided array is created there.

  • Multiple menus can be created.

  • The menu is hidden with visibility: hidden so it is more light when it is opened again.

Add the Styles

<link rel="stylesheet" href="coherent-gameface-components-theme.css">
<link rel="stylesheet" href="style.css">

To overwrite the default styles, simply create new rules for the class names that you wish to change and include them after the default styles.
