Enabling/Disabling Blood from Commands.

I have my blood effects all set-up, but I'd like players to be able to enable and disable the blood with a command. I'd like to use only one command for this (/blood). How would I go about doing this? Would it be easy to just use HashMaps and check if the player isn't in the hashmap, add them to it and disable to blood. or is there a much easier way to do it?

Blood:

Code:java

@EventHandler
    public void onDamage(EntityDamageEvent event) {
        Entity e = event.getEntity();
        if(e.getType().isAlive()) {
            e.getWorld().playEffect(e.getLocation().add(0, 1, 0), Effect.STEP_SOUND, 55);
        }
    }

All help is appreciated!

List<String> showFor = new ArrayList<String>();

Use player names.

 

TryB4 Alright, Thanks!

 

To finish the hint from above:

Code:java

if(showFor.contains(sender)) {
//code to turn it off
showFor.remove(sender);
}
 
else {
showFor.add(sender)
}

This is writting on my tab so some mistakes are possible :-$

 

TryB4 Ok, I tried this:

Code:java

public static List<String> blood = new ArrayList<String>();
@EventHandler
    public void onDamage(EntityDamageEvent event) {
        Entity e = event.getEntity();
        if(e.getType().isAlive()) {
            if(blood.contains(event.getEntity())) {
                event.setCancelled(true);
            } else {
                e.getWorld().playEffect(e.getLocation().add(0, 1, 0), Effect.STEP_SOUND, 55);
            }
        }
    }
public boolean onCommand(CommandSender sender, Command cmd, String string,
            String[] args) {
        Player player = (Player) sender;
        if(cmd.getName().equalsIgnoreCase("blood")) {
            if(Handlers.blood.contains(player.getName())) {
                Handlers.blood.remove(player.getName());
                player.sendMessage(ChatColor.GREEN + "Blood was " + ChatColor.RED + "Enabled!");
            } else {
                player.sendMessage(ChatColor.GREEN + "Blood was " + ChatColor.RED + "Disabled!");
                Handlers.blood.add(player.getName());
            }
        }
        return false;
    }

I get the messages (Blood enabled, Blood Disabled) but its not actually disabling the blood. Any suggestions?

You're checking if it has an entity ^_^
Firstly, check if it's a player.

Code:java

if (e.getEntity() instanceof Player){
if (blood.contains(((Player)e.getEntity()).getName()) { // list has player
 
}
 
}

 

TryB4 This is what I did, but it still shows effects...

Code:java

if (event.getEntity() instanceof Player){
if (blood.contains(((Player)event.getEntity()).getName())) {
event.setCancelled(true);
} else {
e.getWorld().playEffect(e.getLocation().add(0, 1, 0), Effect.STEP_SOUND, 55);
}
}

Does it have to be something other than event.setCancelled(true);?

 

Epicballzy Because you are just canceling the event if it contains the Player's name. You need to have the code that displays the blood in the if statement, not the else. You shouldn't be canceling the event at all, since all you are doing is displaying blood
