[1.7.2] Select random online player

[MrTeddy]

After failing to find any well written documentation I turned to the next best thing, the source and still came up empty handed with what I'm trying to do. Essentially I am trying to select a random player who is online on the start of a mini-game as long as there are at least 3 players online. I'd also need away to store this player in a variable and be able tell when they are killed, as well as how many players are still alive.

 

I don't even know if its possible so I guess my questions are: is it possible to do this? If so, can anyone help point me in the right direction into figuring this out. I'm not that good yet with Java but I don't really learn by reading or watching videos, I learn best by doing so some hint of the right way to look into this would be extremely helpful.

 

Thanks!

You might want to check how Command Blocks track players on a server; I think this will be of the most help to you. As for accessing that code, maybe use events? Anyway, the first thing I would do is look at the Command Block functions.

Not sure you need a mod for this, like MrArcane says you may be able to do it just with command blocks in a map.

 

If you actually want to mod it, then you should look at these methods:

All players on the server: MinecraftServer.getServer().getConfigurationManager.playerEntityList

All players in a world: world.playerEntities

 

You can get the lists, get the size, generate a random number between 0 and size-1 and then get the playerEntity that has that position in the list.

It isn't the only thing in the mod, just for a feature in the mod. Thank you however for the tip, I'll take a look!

 

Update: That was the right place to look, easier than I figured. Got it all working, thanks!
