Theme

The Theme API allows mods to create and register custom themes, change the active theme at runtime, and inject custom CSS into the game.

Importing

import { Theme } from "@hotbunny/hackhub-content-sdk";

Registering a Theme

Create a custom theme by providing a partial configuration. Any property you don't specify will automatically inherit from the Default (Bear OS) theme.

Theme.register("my-dark-theme", {
    name: "My Dark Theme",
    colors: {
        taskbarBg: "#0a0a0f",
        accentColor: "#e94560",
        windowTitlebar: "#1a1a2e",
        windowBg: "#16213e",
    },
    taskbar: {
        position: "floating",
        borderRadius: "1rem",
        blur: true,
    },
    windows: {
        controlsStyle: "traffic-light",
        controlsPosition: "left",
        borderRadius: "0.75rem",
    },
});

Activating a Theme

Theme.setActive("my-dark-theme");

Getting the Active Theme

const current = Theme.getActive();
console.log(current.id); // "my-dark-theme"
console.log(current.colors.accentColor); // "#e94560"

Listing All Themes

const themes = Theme.getAll();
themes.forEach(t => console.log(t.id, t.name));

Injecting Custom CSS

For advanced customization beyond the config, you can inject raw CSS:

const cssId = Theme.injectCSS(`
    .my-custom-widget {
        background: rgba(0, 0, 0, 0.8);
        border-radius: 12px;
        backdrop-filter: blur(10px);
    }
`);

// Later, remove the injected CSS
Theme.removeCSS(cssId);

Notes

• Theme registration should be done in your Bootstrap.OnModPackageLoaded() method.
• The player can always switch back to built-in themes from Settings.
• Mod themes appear alongside built-in themes in the Settings panel.
• Use injectCSS sparingly — prefer the config properties for most customizations.
