Save Hashmap to config.yml

So I'm making an xray detector plugin where it stores the amount of emeralds, diamonds, gold, and iron the player has mined. Everytime I reload / restart the data resets in the hashmap. Then when I type the command in game " /xraycheck (name)" it says some data is null. I need some help, thanks anyway!

 

Config:

Code:java

<playername>:
  <item name>:<item amount>
  <item name>:<item amount>
<playername>:
  <item name>:<item amount>
  <item name>:<item amount>

Code:

Code:java

getConfig().set(player.getUniqueID().toString() + "." + materialName, amount);

Show your code!

During the onDisable method, make sure to loop through the HashMap, saving the "keySet" to a file.

Then, during the onEnable, simply loop through the keys of the config, storing them in a HashMap. :3

 

Sorry valon750 & TheMcScavenger I don't really understand it, I've never really made a plugin with a config. How would I make it so it says http://pastebin.com/2NF5tYyN

 

I already posted the code, it's not that hard.

 

How do I make the config.yml like that, that's the part I don't understand TheMcScavenger

This:

 

So I post that on the onEnable? mythbusterma

You put that whenever you need to save it, don't forget to follow it with saveConfig() (I think that's what it is...).

 

So that's how I "generate" the config? mythbusterma

 

The configuration file is automatically generated on "saveConfig()" when it doesn't exist.

 

Also here is my code, if you needed that to help me...

So I would put the code you said on the onDisable, cause that's where you save it?

That depends when you want to save it lol.

Also when a Player logs off and you free the map entry. Also, you should probably not be using the Player's name to store the associated values, as the switch to a UUID-based system is imminent.

 

I have no idea what I'm doing right now, cause I'm really confused...

I don't really know what to tell you, we've explained how to do this about as well as we can.

 

Could you take my code, and add it where you would? mythbusterma

Bump

CBaer4848 mythbusterma He's not going to spoon feed, 2 or more people have it explained it clearly to you now.

 

I've tried the code, and I get an error when I try to apply it. I'm just asking him / her where they would put it. Maved

So I've figured out how to make it work with the config, but it doesn't update in game with the command. Any help?
