Getting all items from an ArrayList

To obtain all elements from an arraylist, you can utilize a for loop.

Code (Text):

for(Player players : arrayList) {}
 

Then of course, you can use players and execute any methods to all elements in the arraylist.

 

either

Code (Text):

for(Player player : playerList) {
//Do stuff
}

Or (Java 8 only):

Code (Text):

playerList.forEach(player -> {
//Do stuff
});

 

Is the List a List<String> or a List<Player>?

 

Are there any values in the list?

 

Are there any errors in the console or anything like that?

 

Is the "r" message being broadcasted? If so, it means that getPlayer(player) is returning null, which means the string name does not match any online player.

If "r" is not being broadcasted, it means the list is empty. I suggest you add a null check inside the loop, and a length check before it, for debugging.

Code (Java):

Player getp = Bukkit.getPlayer(player);
if(getp != null)
    getp.teleport()....

Oh, if this is meant to store long-lasting data, use UUIDs instead of player names, to anticipate player name changes. player.getUniqueId().toString(); and UUID.fromString(); i believe are the methods used.

 

That's not a valid String list, that's why. A string list in yaml would be

Code (Text):

Teams:
    Red:
        - Something
        - Something Else

 

I am not at all familiar with yml (i use .txt or .nbt, because .yml is a flaming disaster with highly fallible formatting), but that looks like a list of named booleans, not strings.
Also make sure the indentation is correct and there are no newlines/tab whitespace, yml hates that stuff.

 

With the kind of format that I showed you
