Make a per player based boolean?

Hey guys

I wanted to create a boolean that is only accessible per player. Currently I have a regular boolean and when triggered by an event, goes to true. Problem is, everyone on the server gets the true, I only want the player who triggered it to get the "true".

How would I do this?

 

In order of efficiency/sense:
Store their names in a set.
Store their names in a list.
Store them in a hashmap<string, boolean>.
Make a custom player wrapper object.

 

Im no expert, but a couple ideas.

1 - Have a seperate instance of the class for each player needed the boolean.
2 - Keep a map<String, Boolean> to keep track. So you could do if (map.getValue(PlayerName)) .

 

Edit: Already beaten to it.

HashMap.

HashMap<String, Boolean> PlayerBoolean = new HashMap<String, Boolean>();

then...

PlayerBoolean.put(player.getName(), true/false);

 

Ha, alright lemme try to do it. I'm not sure how :$

Just for general housekeeping variables are like helloWorld not HelloWorld, which implies it's a class/object etc

 

Alright, how do I return the value? I have the HashMap setup (new to this) but now I need to check if the player's data is true or false

 

Code:

Boolean someBoolean = yourHashMap.get(player.getName());

 

It would be easier to use a Set<String>:

Code:

Set<String> playerStuff = new HashSet<String>();

playerStuff.add(player.getName()); // set to "true"

boolean playerHasStuff = playerStuff.contains(player.getName());

playerStuff.remove(player.getName()); // set to "false"

Because with hashmap you'd have to also handle null value which comes when the key-value pair does not exist (or the value is actually null).

 

A Set would be best

 

I used set and it worked, problem now is I'm getting issues like:

Might not be related to your plugin.

 

It is, I removed it and it never happened :/

 

Qwahchees
Coincidence maybe... do serval tests with it on/off and see if it happens again, otherwise it was just a packet error as the name suggests.

 

Alright, thanks Digi!
I cleaned up the code and removed some redundant if statements, will that help?

 

Hey I am really new to HashMaps and HashSets so can you help me explain what to do? Can Qwahchees post the code for your hashset?
