Assign players to 1 of 8 teams

Hello everyone, I'm making a UHC plugin. I'm almost done except I can't figure out a way to assign players to their teams. Forgive me if this task sounds too easy, but I've been knee deep in code for the past week since I'm also trying to integrate this plugin with a server's Game API. My brain is exhausted, and I just can't fiure out a way. There are 8 teams, and when the game starts, players are randomly assigned to their teams. How would i go about doing this?

How many players in the game?

I would:
1) Loop through all the online players.
2) Generate a random number
3) Create ints for each team.
4) If the int goes above online players.size(); / 8 then generate another random number...
5) Add them to the team.

Seems confusing

 

No, it seems completely un-confusing (if that's a word) to me. Thanks a lot for the solution.

 

thecreator153 mark as solved please

 

thecreator153 please note that CraftCreeper6 solution won't create equal sized teams.

Uhm, I am pretty sure it will.

It's selecting a team randomly and your not saying to do anything about not selecting the same team until all the others are selected.

 

CraftCreeper6 No it won't. It will create a random number for each player. Technically, there's a chance that every player will be assigned to the same team.

I would do it like this:

Code:java

ArrayList<UUID> players = new ArrayList<UUID>();
for(Player p:Bukkit.getOnlinePlayers())
players.add(p.getUniqueId());
Iterator<UUID> it = players.iterator();
for(int ind = 0;ind<(players.size()/8)+1;ind++)
for(int i = 1;i<=8;i++)
if(it.hasNext()){
//Add player to team using
//Bukkit.getPlayer(it.next());
}

 

I would create a new list containing all the players that will be added to teams, shuffling it, then adding players to each team. Collections.shuffle(List<?>) is what you want to use. Then you can either divide up the collection and add each few players to each team, or circle through all the teams and add players one at a time.

I think you'll find that I said check if the size of the Integer is lower or equal online players / 8

 

This still won't do anything. A random number is random lol. There's no way to make sure that the teams will be equally distributed.

You also edited your post like 30 minutes ago

I edited what post 30 minutes ago?

 

That is so you could add a player to a list that the number corresponds to. Using Random.nextInt(8) or even
((int)(Math.random() * 10) % 8)) would be better. You didn't specify on how to generate a random number and I just listed 2 good ways, both ways not needing to check if the number is above 8.

An equal way to distribute players among teams evenly would be:

• Create List with all online players in it
• http://docs.oracle.com/javase/7/docs/api/java/util/Collections.html#shuffle(java.util.List)
• Make an int equal to List.size() / 8
• Make another int
• Loop through the online players list and add the players to the 1st team.
• When you add a player, increment the other int and when it goes above the list.size() / 8, move to the next list.

I had this in mind if you are storing your teams (a collection of some sort) in an ArrayList.
