一个可以在聊天区输入代码的代码，和普通的不太一样

const admin = ['', '1223455']
global.find = n => world.querySelectorAll('player').find(e => e.player.name == n);
global.kick = n => find(n).player.kick();
global.AP = world.querySelectorAll('player')

world.onChat(async ({ entity, message }) => {
    if (message.startsWith("/")) {
        if (!entity.isPlayer || message[0] != '/') return;
        const code = message.trim().slice(1);
        try {
            world.say('<~ ' + eval(code));
        }
        catch (e) {
            if (e instanceof SyntaxError)
                world.say('语法错误\n<~ ' + e);
            else if (e instanceof InternalError)
                world.say('内部错误（一般是喵循环或者爆栈）\n<~ ' + e);
            else if (e instanceof RangeError)
                world.say('值不在集合中\n<~ ' + e);
            else if (e instanceof ReferenceError)
                world.say('引用错误\n<~ ' + e);
            else if (e instanceof TypeError)
                world.say('类型错误\n<~ ' + e);
            else
                world.say(e);
        }
    }
});
