I want to create a visual link to another 3D room or URL

For links, you can either use the builtin <link> tag in your JML, or you can create a custom object that teleports the user to your room of choice, using javascript:

<FireBoxRoom>
    <Room>
        <Link js_id="my-link" pos="5 0 0" href="./mycoolroom.html" title="Go to My Cool Room" />
    </Room>
</FireBoxRoom>

<FireBoxRoom>
    <Assets>
        <AssetImage id="mycoolroompng" src="./mycoolroom.png" />
    </Assets>
    <Room>
        <Object js_id="my-custom-link" id="cube" collision_id="cube" image_id="mycoolroompng" onclick="location.href='mycoolroom.html';"/>
    </Room>
</FireBoxRoom>
