So i was wondering if someone could make a plugin that freezes the players you want to freeze, and then you can write like "/unfreeze start" and then the countdown start from like 5sec and at 0 they all are unfreezed. Like if you want some kind of race etc. Thanks.
If you want it for racing, there is plugins for that. As for a freeze plugin, you can try this one. http://dev.bukkit.org/server-mods/freeze/
