Need help with data management

I need help, I need to store and get 3 variable,
The variables are :

String name;
Player player;
Integer amount;

I can't store them on a config file because they cannot be initialized until the admin executes a command.

 

How long are these variables needed? Are they just these three or do you need a copy of these three variables for each player? Online players online or online and offline players?

Well, you may not be able to store them in the plug-in's configuration file, but you may still be able to store them in a YML file or another form of flat file.

 

What I need it to do is :

1. player types a command (done)
2. check if command is right (done)
3. check if the name exists (done)
4. if it does assign two values : Player and amount (my probelm)

Can you pleas teach me how to do that?

 

@Mixcoatl
I don't even think a Player can be stored, regardless (though obviously you just work around it with the player's name)

As for the OP, like Mix said, it would help greatly if we knew what your actual intent was with the variables

EDIT:
Ah, already did before I posted

 

Do you want me to send the code I wrote up to this point?

 

@beatcomet
Source is always useful, yes.
Helps us see the 'greater picture', so we know exactly what your intent is (and often, this helps solve issues you haven't even come across, before they happen)

 

I'm assuming you're storing this mapping in memory presently and just need to be able to save them and load them back up when necessary?

There are two sides to this: saving and loading. Since I don't know what you're data structure looks like it's hard for me to give you code that will just work. I would provide pseudocode but I'm not sure that will be helpful. How are you keeping this data in memory right now?

Correct; you wouldn't attempt to write the player object, itself. You would have to use its name or some other uniquely identifying characteristic. But we don't even know how the information is being represented in memory, yet.

 

Here :

BTW, now I noticed that I wrote the messages worngly ([redeened] instead of [redeemed]) xD
note that it's not done yet

yes

Check the code above

That is the plan

anyone?

Edit : Iv'e been thinking, and I think I found a solution :

I will add a PlayerJoinEvent, and because all the code generated buy my plugin are set to be keys, I can get a key list and add each player's name to the key with a certain value.
It may be a little messy but I think it will work

Edit 2 : I got an event better idea :

When a player executes a command it will check if the key (code) contains the players name, if the player is not there it will add him with the default value!
