Nested Radials

Sorry for the late response, but nested radial menus should actually work You could just call player.showRadialMenu() in the callback again. Just make sure that in the outer radial menu "closeOnSelect" is set to false, otherwise it won't work properly:

player.showRadialMenu(icons, entries, null, false, (selection) -> {
    player.showRadialMenu(icons2, entries2, true, (selection2) -> {
        System.out.println("Selected: " + selection2);
    });
});

We'll also add a new player.hideRadialMenu() method with the next update which gives more control over showing and closing radial menus
