This script adds a customizable weapon. It can be used in versions 1.9 onwards (with modifications it can be compatible with previous versions). COMMANDS:

/weapon (mcjs.commands.weapon)

        .permission("commands.command")
        .target(CommandTarget.ALL)
        .async(false)
        .build(), function (context) {
            API.message(context.getSender(), "&aHello World!");
            return true;
        });
