Instruction

Setting up

Fork this repo, clone it, and then run npm install and npm start. HUD should start on the 3500 port. For this to work have HUD Manager opened so it will pass CS2 data to the HUD.

Identifying HUD

In /public directory edit hud.json so it fits you - fill HUD's name, author, version, specify the radar and killfeed functionalities. At the end replace the thumb.png with your icon :)

Building & distributing

To build version to distribute and move around, in the root directory run npm run pack. It will create the zip file for distribution. Now you can just drag and drop this file into the HUD Managers upload area.

Signing

To create Signed HUD to prevent at least from modyfing compiled Javascript files run npm run sign. It's the same as npm run pack command but with additional step of signing .js and .css files and hud.json.

File structure

The HUD is seperated into two parts - the API part, that connects to the HUD Manager API and communicate with it: src/App.tsx file and src/api directory. Usually, you don't want to play with it, so the whole runs without a problem. The second part is the render part - src/HUD, src/fonts and src/assets are the directories you want to modify. In the src/HUD each element of the HUD is seperated into its own folder. Styles are kept in the src/HUD/styles. Names are quite self-explanatory, and to modify style of the element you should just find the styling by the file and class name.

panel.json API

To get the incoming data from the HUD Manager, let's take a look at the src/HUD/SideBoxes/SideBox.tsx component:

const Sidebox = ({side, hide} : { side: 'left' | 'right', hide: boolean}) => {
    const [ image, setImage ] = useState<string | null>(null);
    const data = useConfig('display_settings');

    useOnConfigChange('display_settings', data => {
        if(data && `${side}_image` in data){
            const imageUrl = `${apiUrl}api/huds/${hudIdentity.name || 'dev'}/display_settings/${side}_image?isDev=${hudIdentity.isDev}&cache=${(new Date()).getTime()}`;
            setImage(imageUrl);
        }
    }, []);

    if(!data || !data[`${side}_title`]) return null;
    return (
        <div className={`sidebox ${side} ${hide ? 'hide':''}`}>
            <div className="title_container">
                <div className="title">{data[`${side}_title`]}</div>
                <div className="subtitle">{data[`${side}_subtitle`]}</div>
            </div>
            <div className="image_container">
                {image ? <img src={image} id={`image_left`} alt={'Left'}/>:null}
            </div>
        </div>
    );
}

You can just read data from the HUDs settings by using useConfig hook. Everything is now strictly typed. If you make a change to panel or keybinds JSON files, Vite server will automatically generate types for you, so useConfig should always be up to date.

If you want to listen for a change in settings, you can use useOnConfigChange. In this case we are using this to force refresh src attribute of the img element.

If you want to listen for action input, you can just use useAction hook, like here in Trivia.tsx:

useAction('triviaState', (state) => {
   setShow(state === "show");
});

For the action input we need to import the actions object and create listener with the parameter on it.

keybinds.json API

Keybinds API works in very similiar to panel.json action API. This time the example will be from RadarMaps.tsx:

useAction('radarBigger', () => {
   setRadarSize(p => p+10);
}, []);

useAction('radarSmaller', () => {
   setRadarSize(p => p-10);
}, []);

Killfeed

Because our csgogsi has the ability to process input from HLAE's MIRV, listening for kills is very easy. We can see than in src/HUD/Killfeed/Killfeed.tsx:

componentDidMount() {
	GSI.on("kill", kill  => {
		this.addKill(kill);
	});
}

The Killfeed component basically just keeps kills in the state during the round, and after the round it cleans the state. Kills have CSS animation, that makes them gently show, and after a few seconds disappear, the experience is very smooth. You can fiddle with the styling in the killfeed.css This killfeed detects who killed whom, if there was an assist (flash assist as well), used weapon, headshot and wallbang.

Radar

Radar is custom React-based component, made by Hubert Walczak, and is easily editable from css.
