Scheduler help {solved]

I'm trying to get a value from an event into a delayed scheduler. However when I try to do this, it says I "Cannot refer to a non-final variable player inside an inner class defined in a different method"

I can't set the variable to final though, but I still need it referenced in the task every time it gets called.

Code:

 
Map<Player, Boolean> Immune = new HashMap<Player, Boolean>();   
     
public void onEntityDamage (EntityDamageEvent event) {
Player player = (Player) event.getEntity()
 
plugin.getServer().getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
 
                public void run() {
                    Immune.put(player, false);
                       
                }
            }, 20L);
}

How would I reference "player" in the task?

 

First of all: Map<Something, Boolean> is a wrong collection design! You only need 2 states: yes or no. And you can use a HashSet for that: if a player is in there, it is true, otherwise false.
So you should use a HashSet<String>, with the values being the active player names.

Regarding your actual problem: You could either pass the player('s name) to your class that implements Runnable, or just make the local variable final, as you IDE suggested. I can't see a reason why you wouldn't be able to.

You could just do:

Code:

final String playerName = player.getName();

And then use that String in your run() method.

 

Oh, yeah. I was thinking it would create a variable that could never be changed, but it's re-created every time the event is called...(I think)

Thanks.
