给大家贡献一些好♂玩的代码，可以在自己的地图作品中招♂待一些朋友；

1.喵锁定器

const targetList = ['喵1号'];
targetList.push('替换为你想锁定的人');
targetList.push('可以复制无数条');
const lockPosition = new Box3Vector3(喵, 12, 喵);

world.onPlayerJoin(async ({entity}) => {
    if (targetList.includes(entity.player.name)) {
        while (1) {
            await sleep(喵);
            entity.position = lockPosition ;
        }
    }
});

这段代码可以让指定的人在某个位置动弹不得，人名直接替换即可，可以复制；锁定的位置在第4行的三个数字，也可以自行修改。

2.喵诱捕器

const targetList = ['吉吉喵'];

world.onPlayerJoin(async ({entity}) => {
    if (targetList.includes(entity.player.name)) {
        entity.position = new Box3Vector3(喵, 12, 喵); ;
    }
});

这一段代码呢，会首先在空白地图中央生成一个9*9*9的“VIP房间”，咳咳，用来准备招待我们尊贵的客人； 然后会检查新加入的玩家是不是我们设置的尊贵的客人，也就是代码中targetList的部分啦； 如果是尊贵的客人，就会请他到VIP房间里玩♂一玩；   请注意！这两段代码没有做兼容性检查哦！请考虑合适的使用时机！   实际效果可以参考这里的demo（有效期为24小时，超时看不到就算啦！等我发布地图吧！）   https://box3create.codemao.cn/games/6b4a7e15dcab7beb5d74?p=iPxcNQPqUOh0gYt1ajDJyLLQ6e4pvUKQpALNNV%2Ffz5A9Po3wbeLgVndWVzdA%3D%3D   当然了为了让大家都能体验到效果，这个demo里面的代码和上面的略有区别，以这篇post写的为准哦！
