    Hi guys, I need some help here,
    I need help checking if a config node exists, but I have no idea how (I'm not using fixed nodes, I depands on the command executer).
    If it's better to use anything other that a config file just tell me :)
    Here is how I need it to work :

    1. A player uses a command
    2. Check if the node exists, if not set a node with the player's name with a value of 1.

    This is it, the rest should be easy to do.

    thanks guys :)

    Use a hashmap.

    HashMap<player, boolean> hashmap = new HashMap<player, boolean>();
    hasmap.put(player, true); //Puts the value true for the player in the hashmap

    if (hashmap.get(player)) { //returns true if value is "true" for the player
    //stuff
    }

    if (hashmap.get(player) == null) { //The get method returns null if the player is not in there

    Something like (for a yml configuration):
    Code:
    if (config.getString("node", null) == null){
            config.setProperty("node", "1");
}

    Can I do something like this :

    Code:java
    1.  
    2. HashMap<String, Integer> hashmap = new HashMap<String, Integer>();
    3. String name = player.getName();
    4.  
    5.  
    6. if(hashmap.get(name) == null
    7. {
    8. hashmap.put(name, 1)
    9. }
    10. if(hashmap.get(name) == 1)
    11. {
    12. player.sendMessage("you can do it")
    13. hashmap.put(name, 0);
    14. }
    15. if(hashmap.get(name) == 0)
    16. {
    17. player.sendMessage("you cannot use it any more")
    18. }
    19.

    why not use "hashmap.containsKey(name);" ?

    should I use instead of using the null check?

    I'm trying to limit the amount of times a player can redeem a code buy using the HashMap, but It allows me to redeem it just once no matter what I do.
